Exporting Mushrooms from Canada to US: FDA and USDA Guide

Exporting mushrooms from Canada to the United States means navigating a layered regulatory framework where a single misstep on a permit, certificate, or tariff classification can halt a shipment at the border. Fresh Agaricus mushrooms carry the heaviest compliance burden: they require a USDA APHIS import permit, a CFIA phytosanitary certificate for every load, FDA Prior Notice filed within strict time windows, and an FSVP program managed by the U.S. importer. At the same time, antidumping and countervailing duty cash deposit rates, currently zero percent for all Canadian producers, must be verified before every shipment because they can change after each administrative review. Processed forms such as dried, frozen, and prepared mushrooms shift the regulatory load: they drop the USDA permit but add FDA canning regulations for preserved products and keep full FSVP obligations across every category. This guide walks through each requirement in the order exporters encounter them, from CFIA licensing and USDA permits through ACE entry filing, USMCA origin certification, and the extra documentation needed for organic shipments under the COR-NOP equivalency.

2024 AD/CVD Duty Rates by Canadian Producer

Antidumping and countervailing duty cash deposit rates apply to fresh and chilled Agaricus mushrooms from Canada and vary by named producer. The U.S. Department of Commerce assigns individual rates to mandatory respondents and a single "All Others" rate to non-investigated companies. Deposits are collected at entry and reconciled after administrative reviews. Exporters should verify the latest Federal Register notices before every shipment because rates can change after each review cycle. Canada exported 70.1 million kilograms of Agaricus mushrooms in 2024 according to Statistics Canada making duty exposure a significant cost factor.

AD/CVD rate table by producer with combined deposit percentages

Producer	Antidumping Duty Rate	Countervailing Duty Rate	Combined Cash Deposit
Champ's Mushrooms	0.00%	0.00%	0.00%
Farmers' Fresh Mushrooms	0.00%	0.00%	0.00%
Highline Mushrooms	0.00%	0.00%	0.00%
All Others	0.00%	0.00%	0.00%

The table reflects the most recent published rates where all named respondents and the All Others category received zero percent combined deposits. Cash deposits are calculated on the entered value and held by CBP pending liquidation. Importers must post a continuous bond sufficient to cover potential liability if rates increase in a future review.

How Commerce assigns producer-specific vs. all-others rates

Commerce selects mandatory respondents based on export volume during the period of investigation. Those companies receive individual margins calculated from their questionnaire responses. All non-investigated producers receive the All Others rate which is typically the volume-weighted average of the individual respondent rates. A producer can request a separate rate certification if it demonstrates independence from government control and provides complete sales and cost data.

Where to verify rate changes in Federal Register notices

Final results of administrative reviews are published in the Federal Register and summarized in Commerce's International Trade Administration case docket for A-122-804 and C-122-805. Exporters should monitor the ITA case timeline for preliminary and final results. The Federal Register notice includes the effective date for new cash deposit rates and instructions for CBP implementation. Subscribing to the ITA email alerts for these case numbers ensures timely notice of changes.

USDA APHIS Permits and Phytosanitary Certificates for Fresh Mushrooms

Exporters must secure a USDA APHIS import permit (PPQ Form 587) to ship fresh mushrooms from Canada to the United States. This permit authorizes the entry of specific mushroom commodities and must be obtained by the U.S. importer before the first shipment arrives. A phytosanitary certificate issued by the Canadian Food Inspection Agency accompanies each shipment to certify freedom from quarantine pests. The regulatory framework supports a massive trade volume, as Canadian mushroom growers sold 163,769 short tons of mushrooms in 2024 according to Statistics Canada. This scale underscores the necessity of strict permit compliance for market access.

PPQ 587 permit application timeline and renewal requirements

The U.S. importer submits PPQ Form 587 through the APHIS ePermits system or by mail to the Plant Protection and Quarantine Permit Unit. Processing typically takes 30 to 60 days, so you should apply well before the first planned shipment. The permit is valid for up to three years and lists the approved commodities, origin, and port of entry. Renewal requires a new application before the expiration date. Amendments for additional commodities or ports require a written request to the permit unit.

Phytosanitary certificate issuance by CFIA for each shipment

The Canadian exporter requests a phytosanitary certificate from the CFIA for every consignment. The certificate must reference the USDA import permit number and confirm the mushrooms were inspected and found free of regulated pests. CFIA inspectors verify the growing facility meets U.S. entry requirements including substrate treatment and sanitation protocols. The original paper certificate travels with the shipment and is presented to CBP and PPQ at the port of entry. This process facilitates the export of 70.1 million kilograms of Agaricus mushrooms in 2024, according to Statistics Canada.

Trichoderma Verticillium and nematode mitigation on substrate

Growing media such as peat moss and composted substrate can harbor Trichoderma, Verticillium, and nematode species that are quarantine concerns for APHIS. Producers must use pasteurized or treated substrate and maintain facility sanitation to prevent contamination. CFIA inspection focuses on substrate handling records and pest monitoring logs. Shipments found with contaminated substrate at the border are subject to re-export, treatment, or destruction at the importer's expense. Effective mitigation is critical given that almost all (99.6%) of Canada's Agaricus mushroom exports in 2024 were destined for the United States according to Statistics Canada.

FDA Prior Notice Facility Registration and FSVP Importer Obligations

Prior Notice submission windows for land vs air cargo

Prior Notice submission timing depends on the mode of transport. For land crossings from Canada the FDA requires submission no less than two hours before arrival at the border. For air cargo the window is no less than four hours before arrival. The notice is filed electronically through the FDA Prior Notice System Interface or the CBP ACE system and must include the food facility registration number, product description, quantity, lot codes, shipper, consignee and anticipated port of entry. A confirmation number is generated and must accompany the shipment. Failure to file on time results in refusal of admission and the shipment is held at the port until compliance is met or the goods are re-exported or destroyed. Ontario and British Columbia together accounted for 92.8% of Canada's total mushroom sales in 2024 according to Statistics Canada (source).

Food Facility Registration renewal for Canadian mushroom facilities

Every Canadian facility that manufactures, processes, packs or holds mushrooms for export to the United States must register with the FDA under the Bioterrorism Act. Registration is completed online through the FDA Food Facility Registration module and must be renewed during the biennial renewal period from October 1 to December 31 of each even numbered year. The registration number must appear on Prior Notice submissions and on shipping documents. If a facility changes ownership, location or the responsible agent the registration must be updated within 60 days. FDA may suspend registration if a facility is found to pose a serious health risk which would block all shipments from that site until the suspension is lifted.

FSVP importer obligations and qualified auditor requirements

The US importer of record is the FSVP importer and must develop, maintain and follow a Foreign Supplier Verification Program for each Canadian mushroom supplier. The program requires a written hazard analysis, approval of suppliers based on their food safety performance, and verification activities such as onsite audits, sampling and testing or review of the supplier’s food safety records. A qualified auditor who has the technical expertise to perform the audit must conduct onsite audits. The importer must document the basis for determining that the auditor is qualified. FSVP records must be kept for at least two years and made available to FDA upon request. Importers who are also the owners or consignees at the time of entry are responsible for compliance even if a customs broker files the entry.

USMCA Rules of Origin for Duty-Free Mushroom Treatment

Wholly obtained criterion for fresh mushrooms grown in Canada

Fresh mushrooms grown and harvested in Canada qualify as wholly obtained goods under USMCA Article 4.3. This means they meet the origin criterion without any further processing requirements. The grower must be able to demonstrate that the mushrooms were cultivated entirely in Canada using Canadian substrate, water and labor. Supporting records include farm production logs, seed or spawn purchase receipts, and harvest dates. When claiming preferential treatment the importer certifies that the good is wholly obtained and the exporter maintains the underlying documentation for a minimum of five years. No regional value content calculation is required for fresh whole mushrooms classified under HS 0709.51.

Tariff shift rules for dried frozen and value-added products

Processed mushrooms such as dried, frozen or value-added products must satisfy the applicable tariff shift rule in the USMCA product specific rules of origin. Dried mushrooms under HS 0712.30 typically require a change to heading 0712 from any other chapter. Frozen mushrooms under HS 0710.80 require a change to heading 0710 from any other chapter. Value-added products such as mushroom sauces or prepared meals fall under different headings and may require a change to the applicable heading from any other heading or a regional value content test. The exporter must verify the correct HS classification and apply the specific rule for that classification. A tariff shift is met when all non-originating materials used in production undergo the required change in tariff classification.

Certificate of origin completion and record retention

The USMCA does not prescribe a mandatory certificate of origin form. Instead the importer, exporter or producer may complete a certification of origin containing nine minimum data elements including the certifier name and contact information, exporter and producer details, importer details, description and HS code of the good, origin criterion, blanket period if applicable, authorized signature and date. The certification can be provided on a commercial invoice or a separate document. Records supporting the claim must be retained for at least five years from the date of importation. Canadian exporters should prepare a blanket certification covering multiple shipments over a 12 month period when supplying the same US importer regularly. The certification must be presented to CBP upon request during a verification or audit.

Step-by-Step First Shipment Checklist from CFIA to Border Release

Complete 12-step workflow for first-time exporters covering CFIA registration, permit acquisition, broker selection, ACE filing, and border release procedures.

CFIA export registration and facility licensing steps 1-3

Step 1 requires the Canadian facility to hold a valid Safe Food for Canadians Regulations (SFCR) licence issued by the Canadian Food Inspection Agency (CFIA) for the activity "Exporting Food". Step 2 mandates that the facility develop, implement, and maintain a written Preventive Control Plan (PCP) addressing biological, chemical, and physical hazards specific to mushroom cultivation and packing. Step 3 involves requesting an official export certificate through the CFIA My CFIA portal; for fresh mushrooms destined for the US, this is typically a Phytosanitary Certificate issued under the USDA APHIS pre-clearance arrangement, which verifies freedom from regulated pests such as mushroom phorid flies and nematodes.

USDA permit FDA registration and broker engagement steps 4-7

Step 4 confirms the US importer has secured a USDA APHIS PPQ Form 587 permit for fresh mushroom importation, listing the specific Canadian production site. Step 5 requires the foreign facility to register with the FDA under the Bioterrorism Act, obtaining a unique facility registration number that must be renewed biennially between October 1 and December 31 of even-numbered years. Step 6 designates a US-based FSVP Importer who develops a Foreign Supplier Verification Program evaluating the Canadian supplier's hazard analysis and preventive controls. Step 7 engages a licensed US Customs Broker with a valid CBP permit and Automated Commercial Environment (ACE) access to file entry documents and manage the Single Transaction Bond or Continuous Bond requirements.

ACE entry filing border inspection and release steps 8-12

Step 8 instructs the broker to file the ACE entry summary (CBP Form 7501) prior to arrival, transmitting the HS code, commercial invoice value, USDA permit number, FDA Prior Notice confirmation, and USMCA certification of origin data elements. Step 9 triggers the FDA Prior Notice submission via the Prior Notice System Interface (PNSI) at least two hours before land border arrival or four hours before air cargo arrival. Step 10 prepares the shipment for potential CFIA inspection at the point of origin or USDA PPQ inspection at the first US port of entry, ensuring pallets are accessible and phytosanitary certificates accompany the load. Step 11 addresses CBP examination holds; if selected for intensive exam, the broker coordinates container devanning at a Centralized Examination Station (CES). Step 12 achieves border release when CBP issues the "Entry Summary Accepted" status and FDA issues "May Proceed", allowing the carrier to deliver to the US importer's warehouse.

Product Classification Fresh vs Dried vs Frozen vs Value-Added

HS code decision matrix for mushroom products including fresh (0709.51), dried (0712.31), frozen (0710.80), and prepared (2003.10) with regulatory differences for each.

HS code matrix with regulatory agency jurisdiction per category

Fresh or chilled mushrooms of the genus Agaricus classify under HS 0709.51.00 and fall under USDA APHIS phytosanitary jurisdiction for pest risk and FDA food safety jurisdiction. Dried mushrooms under HS 0712.31.00 lose the fresh pest risk profile, removing USDA APHIS permit requirements but retaining FDA oversight for sanitation and labeling. Frozen mushrooms under HS 0710.80.00 (uncooked or cooked by steaming or boiling in water) require FDA registration and Prior Notice but generally do not require a USDA phytosanitary certificate if commercially sterile. Prepared or preserved mushrooms under HS 2003.10.00 (vinegar, brine, or sauce) are regulated solely by FDA as low-acid canned foods if hermetically sealed, triggering Food Canning Establishment (FCE) registration and Process Filing (SID) requirements.

Product Form	HS Code	USDA APHIS Permit	FDA Prior Notice	FSVP Required	AD/CVD Scope
Fresh/Chilled	0709.51.00	Yes (PPQ 587)	Yes	Yes	Yes (Certain Preserved)
Dried	0712.31.00	No	Yes	Yes	No
Frozen	0710.80.00	No*	Yes	Yes	No
Prepared/Preserved	2003.10.00	No	Yes	Yes	Yes (Subject)

*Frozen may require a permit if not commercially sterile or if soil/debris is present. The table illustrates that fresh mushrooms carry the heaviest regulatory burden requiring dual USDA and FDA clearance. Dried and frozen forms simplify border entry by eliminating the phytosanitary certificate but retain full FDA FSVP obligations. Prepared mushrooms under 2003.10 face unique FDA canning regulations and fall within the scope of the Antidumping and Countervailing Duty orders on Certain Preserved Mushrooms from Canada, unlike the fresh, dried, or plain frozen categories.

FDA USDA CFIA requirements variation by product form

Fresh mushrooms require a CFIA-issued Phytosanitary Certificate based on a growing season inspection or pre-clearance audit, a USDA PPQ 587 import permit held by the US buyer, FDA Prior Notice, and FSVP documentation. Dried mushrooms eliminate the CFIA phytosanitary certificate and USDA permit but require a CFIA export certificate under SFCR for "Exporting Food" and a certificate of free sale if requested by the US importer. Frozen mushrooms need a CFIA export certificate, FDA Prior Notice, and proof of commercial sterility or a written process schedule if blanched before freezing to avoid USDA soil restrictions. Value-added products like marinated or canned mushrooms demand FDA FCE registration (Form 2541), Process Filing (Form 2541a) for each product style and container size, CFIA export certification, and compliance with 21 CFR 113 Thermally Processed Low-Acid Foods regulations.

AD/CVD applicability across processed mushroom categories

The US Department of Commerce Antidumping and Countervailing Duty orders on Certain Preserved Mushrooms (A-122-804 / C-122-805) specifically cover mushrooms prepared or preserved otherwise than by vinegar or acetic acid, classified under HS 2003.10.0127 (buttons) and 2003.10.0131 (other). Fresh mushrooms (0709.51), dried mushrooms (0712.31), and frozen mushrooms (0710.80) are explicitly excluded from the scope. Exporters of canned, jarred, or pouched mushrooms in brine, butter, or sauce must deposit estimated duties at the cash deposit rate assigned to their specific Canadian producer (e.g., Highline Mushrooms, Monaghan Mushrooms) or the "All Others" rate. Misclassifying prepared mushrooms as dried or frozen to avoid AD/CVD deposits triggers CBP fraud penalties and retroactive liability.

Organic Mushrooms COR-NOP Equivalency and Extra Documentation

Organic mushrooms exported from Canada to the United States must satisfy the National Organic Program equivalency established by the USDA and CFIA, requiring specific documentation to prove organic integrity at every stage of the supply chain. The Canada Organic Regime and the US National Organic Program maintain a mutual recognition agreement, which allows Canadian organic operations to export directly to the US market without undergoing separate US organic certification, provided the Canadian operator holds a valid certificate from a CFIA-accredited certification body.

COR-NOP equivalency scope and certified body requirements

Canadian organic mushroom producers must hold a valid certificate issued by a CFIA-accredited certification body to export organic product to the United States. This certificate must explicitly state compliance with the Canadian Organic Standards, which are deemed equivalent to the US National Organic Program regulations. The scope of the certificate must cover the specific mushroom species being exported, the growing medium used, and all handling activities from harvest through packaging. US importers must verify that the Canadian operator's certificate is current and covers the exact products and quantities being shipped. The certification body must be listed in the USDA’s Organic Integrity Database to ensure acceptance by US customs and agricultural authorities. Any changes to the production facility or organic management plan must be reported and approved before shipment. Exporters must maintain records of all organic inputs and practices to demonstrate ongoing compliance. Failure to maintain current certification or scope coverage will result in the product being treated as conventional and subject to standard import regulations without organic status.

Organic certificate and transaction certificate for each shipment

Each shipment of organic mushrooms must be accompanied by a Transaction Certificate issued by the Canadian certification body before the goods cross the border into the United States. The Transaction Certificate serves as the primary proof of organic integrity for that specific lot, linking the physical product to the underlying organic management system. This document must include the name and address of the Canadian exporter, the name and address of the US importer, a detailed description of the goods including quantity and weight, the lot number, and the certification body’s reference number. The Transaction Certificate must be issued electronically through the USDA’s Organic Integrity Database to ensure authenticity and prevent fraud. US importers must retain these certificates as part of their FSVP records to demonstrate due diligence. The certificate must cover the entire quantity shipped, and partial shipments require separate Transaction Certificates for each lot. Exporters should request Transaction Certificates at least one week before the expected shipment date to allow time for verification. The certificate must explicitly state that the product meets the requirements of the US National Organic Program.

USDA organic seal usage and labeling compliance

The USDA organic seal may only be used on organic mushroom packaging if the product contains one hundred percent organic ingredients and the final packaging is prepared in a certified organic facility. For mushrooms that are ninety-five percent or more organic, the label may state "made with organic mushrooms" but cannot display the USDA seal. All organic mushroom labels must clearly identify the certified organic operator or producer on the information panel. The label must also list all ingredients and any processing aids used during harvest and packaging. If the mushrooms are grown in a substrate, the substrate must be approved for organic use under US regulations. The net weight declaration must be prominent and conform to US labeling standards. Any claim of organic status must be truthful and verifiable through the accompanying Transaction Certificate. Misuse of the USDA organic seal or false organic claims can result in significant fines and product seizures by the FDA. Importers must ensure that the Canadian exporter’s labeling complies with both Canadian and US requirements before the product is released into the US market.

Packaging Labeling and Traceability Requirements

Exporting mushrooms to the United States requires strict adherence to Country of Origin Labeling, net weight declarations, and lot traceability systems to ensure compliance with US Food and Drug Administration and Customs and Border Protection regulations. The packaging must clearly identify the product as grown in Canada, state the net weight in both pounds and ounces or grams, and include a unique lot code that allows for immediate traceability in the event of a food safety recall. These requirements apply to all forms of mushrooms, whether fresh, dried, frozen, or value-added, and are essential for maintaining market access and avoiding costly border delays or detentions.

COOL marking requirements for fresh and processed mushrooms

Country of Origin Labeling requires that every package of fresh mushrooms exported to the United States clearly state "Product of Canada" or "Grown in Canada" in a conspicuous location. This marking must be in English and easily visible to consumers and customs officials upon arrival at the border. For processed mushrooms such as canned or frozen varieties, the country of origin must be declared on the principal display panel or the information panel of the label. The label must also include the name and address of the US importer or distributor, which is a mandatory requirement for all food imports under FDA regulations. Processed products must additionally comply with the Nutrition Facts panel requirements, listing all ingredients in descending order by weight. Fresh mushrooms do not require a Nutrition Facts panel but must still meet all other labeling standards. The country of origin marking must be permanent and not easily removable, such as a printed label or direct printing on the container. Temporary tags or stickers that can be easily detached are generally not accepted for compliance purposes. Importers should verify that the Canadian exporter’s labeling meets these specific requirements before the product is shipped to prevent hold-ups at the border.

Lot code format for traceability and recall readiness

Every package of mushrooms exported to the United States must carry a unique lot code that links the product to its harvest date, growing facility, and packing date. This lot code is essential for traceability and must be recorded by both the Canadian exporter and the US importer to facilitate rapid recalls if a food safety issue arises. The lot code should include a combination of letters and numbers that uniquely identifies the production batch, such as the facility code, harvest date, and packing sequence. The format must be consistent across all shipments from a given facility to allow for efficient tracking. US importers must maintain records of these lot codes and link them to their purchase orders and shipping documents. In the event of a recall, the FDA requires that the lot code be used to identify the specific products affected and to notify downstream customers. Exporters should ensure that the lot code is printed clearly and legibly on all packaging levels, including inner packs and outer cartons. The lot code must be accessible and not obscured by other labeling elements. Regular audits of the lot code system should be conducted to ensure accuracy and completeness.

Net weight tolerances and package integrity standards

Net weight declarations on mushroom packages must be accurate and conform to US tolerances, which typically allow a small variance in weight to account for moisture loss or handling. The net weight must be stated in both avoirdupois pounds and ounces for fresh mushrooms, or in grams for smaller retail packs. The actual weight of the product in the package must not be less than the declared net weight, except for minor variations allowed by law. Package integrity is critical to prevent contamination and maintain product quality during transit. Packaging materials must be food-grade and suitable for the specific type of mushroom and storage conditions. Ventilation holes in fresh mushroom containers are necessary to prevent condensation and spoilage but must be designed to prevent pest entry. The packaging must withstand standard stacking and handling pressures without crushing the product. Importers should specify packaging requirements in their contracts with Canadian exporters to ensure consistency and compliance. Any damage to the packaging during transit that compromises the product or the label must be reported and addressed immediately. Proper packaging not only ensures regulatory compliance but also protects the product’s quality and marketability.

Conclusion

Exporting mushrooms from Canada to the United States demands precise coordination across CFIA USDA APHIS FDA and CBP systems. The critical path begins with confirming your AD CVD deposit rate by producer code and securing a valid PPQ Form 587 permit before harvest. Phytosanitary certificates must match the commodity description on the permit exactly including variety and treatment codes. FDA prior notice must be filed by the FSVP importer of record at least two hours before land arrival. USMCA duty free treatment requires a completed certification of origin referencing the correct tariff shift rule for your product form. Land crossings demand appointments at APHIS inspection stations during operating hours while air cargo requires advance notice to the port veterinarian. Landed cost models must include AD CVD cash deposits cold chain surcharges and potential re inspection fees. Organic shipments need both COR and NOP certificates with matching lot numbers. Labeling must satisfy both CFIA and FDA requirements including traceability lot codes on every master case. New exporters should conduct a test shipment under 500 kg to validate documentation flow before committing to volume programs. The Global Trade Plaza supplier directory can help identify verified US importers with active FSVP programs and mushroom specific receiving capabilities.

Frequently Asked Questions

how exporting mushrooms from canada to usa

Exporting mushrooms from Canada to the USA requires a CFIA SFCR licence, a USDA APHIS PPQ 587 import permit held by the U.S. buyer, FDA facility registration, and a phytosanitary certificate for each shipment. Fresh Agaricus mushrooms must also comply with AD/CVD cash deposit requirements and USMCA origin rules. A licensed U.S. customs broker files the ACE entry to obtain border release.

exporting mushrooms from canada to us requirements for foreigners

Foreign-owned companies must meet the same regulatory standards as Canadian firms: a CFIA SFCR licence for the facility, a written Preventive Control Plan, FDA food facility registration, and a U.S. importer of record to handle the PPQ 587 permit and FSVP obligations. The foreign entity cannot act as the U.S. importer of record without a U.S. business presence.

exporting mushrooms from canada to us requirements for tourists

Tourists cannot commercially export mushrooms; personal importation of fresh mushrooms is generally prohibited by CBP and USDA APHIS to prevent pest introduction. Commercially packaged, shelf-stable dried mushrooms may be allowed for personal use in small quantities if declared, but fresh product will be seized at the border.

exporting mushrooms from canada to us documents needed

Required documents include a commercial invoice, packing list, USDA phytosanitary certificate referencing the PPQ 587 permit number, FDA Prior Notice confirmation, and a USMCA certification of origin for duty-free treatment. The broker also files CBP Form 7501 entry summary with the HS code and AD/CVD case identifiers.

exporting mushrooms from canada to us costs

Costs include the USDA PPQ 587 permit application fee, CFIA phytosanitary certification fees per shipment, FDA Prior Notice filing (free if self-filed), customs broker fees, freight, and a continuous bond premium. AD/CVD cash deposits apply at the combined rate for the specific producer, currently zero percent for all listed Canadian firms.

what are the current antidumping duty rates for Canadian mushrooms

As of the most recent administrative review, the combined antidumping and countervailing duty cash deposit rate is 0.00% for Champ's Mushrooms, Farmers' Fresh Mushrooms, Highline Mushrooms, and the All Others category. Rates are published in the Federal Register under ITA cases A-122-804 and C-122-805 and can change after future reviews.

what is the HS code for fresh mushrooms exported to USA

The Harmonized System code for fresh or chilled mushrooms of the genus Agaricus is 0709.51.00. This classification determines the USMCA wholly obtained origin criterion and the applicability of AD/CVD orders covering fresh and chilled Agaricus mushrooms from Canada.

how does USMCA affect mushroom exports from Canada

USMCA grants duty-free entry to fresh mushrooms grown entirely in Canada under the wholly obtained criterion (HS 0709.51) without a regional value content test. Processed mushrooms such as dried (HS 0712.30) or frozen (HS 0710.80) must meet specific tariff shift rules. A certification of origin with nine data elements supports the claim.

what FDA prior notice is required for mushroom shipments

FDA Prior Notice must be filed electronically via the Prior Notice System Interface or CBP ACE at least two hours before arrival for land shipments and four hours for air cargo. The filing requires the FDA facility registration number, product description, quantity, lot codes, shipper, consignee, and anticipated port of entry.

can tourists bring mushrooms from Canada to US

No, tourists cannot bring fresh mushrooms from Canada into the U.S. because USDA APHIS prohibits personal importation of fresh produce that hosts quarantine pests. Commercially dried and packaged mushrooms may be admissible in small declared quantities, but fresh product will be confiscated and destroyed at the border.

what causes FDA detention of mushroom shipments at the border

FDA detains mushroom shipments for missing or late Prior Notice, invalid or expired food facility registration, FSVP importer non-compliance, evidence of filth or decomposition, or pesticide residues exceeding tolerances. Det
