The UK depends on EU potato starch to meet roughly half of its domestic demand, creating a stable, high-volume trade lane governed by two distinct regulatory regimes since Brexit. Great Britain operates its own SPS controls through IPAFFS and the CHED-P certificate, while Northern Ireland remains aligned with EU rules via TRACES.NI and the CHED-PP model. Misunderstanding this split, or the Rules of Origin proof required for zero tariff under the TCA, leads to Border Control Post holds, duty re-assessment, and rejected loads. This guide covers the complete compliance chain for HS 110813 shipments from the EU: mandatory certificates, IPAFFS and TRACES.NI workflows, acrylamide and contaminant limits that differ from EU standards, GVMS and transit procedures, and the document pack that satisfies both customs and letter of credit requirements.
You will learn how to classify native versus modified starch correctly, secure preferential origin with an EUR.1 or valid statement on origin, navigate the GB MRL register divergences for glyphosate and chlorpropham, route containers through Sevington or LoLo ports with a valid GMR, and leverage the NI landbridge only when starch qualifies as Northern Ireland goods. Practical timelines, field-level CHED-P guidance, and the exact proof-of-origin wording from Annex ORIG-4 are included so exporters and importers can move compliant loads without costly delays.
The UK remains a significant net importer of starch products, relying heavily on EU supply chains to meet domestic demand. UK demand for starch is approximately 1.45 million tonnes, against estimated UK production of 700 000 tonnes according to Starch Europe. This structural deficit creates a consistent baseline requirement for imported native potato starch, with EU origins dominating the HS 110813 trade flows due to geographic proximity and regulatory alignment under the TCA.
The Netherlands, Germany, France, Denmark, and Poland consistently rank as the top five EU suppliers of potato starch to the UK market. These origins benefit from established logistics corridors via Channel ports and the Eurotunnel, allowing for short transit times that preserve product quality. In 2016 the EU starch industry exported more than 868 000 tonnes of starch products to the UK according to Starch Europe, illustrating the scale of the trade relationship that continues to define current souring patterns.
Native potato starch typically commands a larger import volume share compared to modified variants, driven by its broad application in food processing, paper manufacturing, and adhesives. Modified starches, classified under separate HS codes, attract higher unit values but lower overall tonnage. Exporters should verify the specific HS classification with UK buyers early, as misclassification between native and modified codes triggers incorrect duty assessment and potential SPS inspection delays at the Border Control Post.
Great Britain operates a distinct SPS regime built on retained EU law but managed through domestic digital systems. Importers must pre-notify shipments via the Import of Products, Animals, Food and Feed System (IPAFFS) and obtain a Common Health Entry Document for Plants (CHED-P) before arrival at a GB Border Control Post. A GB-specific health certificate, issued by the competent authority in the EU member state of origin, accompanies each consignment certifying compliance with GB contaminant limits and acrylamide benchmarks.
Northern Ireland continues to apply EU Sanitary and Phytosanitary rules directly under the Windsor Framework. Consignments destined for NI are pre-notified on TRACES.NI and move under standard EU intra-community trade procedures without a CHED-P. The health certificate follows the EU model (CHED-PP equivalent) and references EU maximum residue levels and contaminant regulations, simplifying the administrative burden for exporters shipping directly to Belfast or Warrenpoint.
Qualifying Northern Ireland goods enjoy unfettered access to the Great Britain market, meaning potato starch produced or customs-cleared in NI can move to GB without additional SPS checks or IPAFFS pre-notification. However, starch originating in the EU that merely transits through NI without substantial processing does not qualify. Exporters using the NI landbridge must maintain commercial evidence of NI origin or processing to claim the exemption when the haulier presents the Goods Movement Reference at the GB port.
Exporters must assemble a complete document pack before the consignment departs the EU to avoid delays at the British Border Control Post. The checklist covers three pillars: mandatory SPS certificates, pre-notification via IPAFFS, and commercial paperwork that satisfies both customs and the buyer’s letter of credit requirements. Total EU-27 starch potato cultivation was estimated at 201.000 hectares in 2024, the lowest in eight years according to Boerenbusiness, tightening raw material availability and making compliant logistics even more critical.
The Common Health Entry Document for Products of Animal Origin (CHED-P) is the single mandatory SPS certificate for native potato starch entering Great Britain. It must be issued by the competent authority in the EU member state of dispatch and reference the specific EU establishment approval number, the HS code 110813, and the attestation that the product complies with GB contaminant limits for acrylamide, heavy metals, and mycotoxins. The original signed CHED-P travels with the load; a copy is uploaded to IPAFFS during pre-notification. Missing or mismatched establishment codes are the most common cause of BCP holds.
IPAFFS pre-notification must be submitted at least 24 hours before the consignment arrives at the GB Border Control Post, though 48 hours is standard practice to allow for BCP slot booking. The submission generates a Unique Notification Number (UNN) that the haulier must present in the Goods Vehicle Movement Service (GVMS) to create the Goods Movement Reference (GMR). Without a valid UNN linked to the CHED-P, the GMR cannot be finalised and the vehicle will be turned away at the check-in gate. Amendments after submission require a new UNN and restart the clock.
The commercial invoice must show the buyer and seller EORI numbers, Incoterms 2020, net and gross weight per pallet, and a declaration of EU preferential origin to claim zero duty under the TCA. The packing list details pallet count, dimensions, and batch codes traceable to the CHED-P. A technical specification sheet listing moisture, starch content, pH, viscosity, and acrylamide test results supports the SPS attestation. Transport documents, CMR, bill of lading, or rail consignment note, must match the vehicle registration and trailer number declared in GVMS.
Setting up IPAFFS access and mastering CHED-P completion are prerequisite operational capabilities for any EU starch shipper targeting Great Britain. The process involves business verification, user role assignment, and precise data entry aligned with the HS 110813 commodity code. Germany's starch potato area was set to fall by more than 2.800 hectares to 53.100 hectares according to Boerenbusiness, reflecting a consolidating supply base where efficient digital compliance becomes a competitive differentiator.
Register the legal entity on the GOV.UK IPAFFS portal using the Great Britain EORI number (starting with GB) and the company registration number from the EU member state. The primary account holder completes identity verification via Government Gateway and assigns roles: "Submitter" for daily CHED-P filing, "Viewer" for logistics partners, and "Approver" for final sign-off. Each role requires a separate Government Gateway login. Verification typically completes within one working day but can extend to five days if Companies House cross-checks flag discrepancies.
In the CHED-P commodity section enter HS code 110813 and the description "Native potato starch, not chemically modified". Reference the EU establishment approval number exactly as it appears on the health certificate (format: CC-NNNN). Input the net weight in kilograms, number of packages, and pallet identifiers. Attach the PDF of the signed official certificate and the acrylamide test report. The "Transport" tab requires the vehicle registration, trailer number, BCP of entry, and estimated date and time of arrival. Any mismatch between the CHED-P and the CMR triggers an automatic documentary check.
Submit the CHED-P on IPAFFS no later than 24 hours before the estimated arrival at the BCP; the system rejects submissions with an arrival timestamp in the past. Once submitted, the UNN is valid for 72 hours, if the shipment is delayed beyond this window, a new pre-notification is mandatory. At the BCP, the haulier presents the GMR and the original CHED-P for documentary identity and physical checks. Physical check rates for native starch are currently low but any detection of non-compliance triggers a 100 percent check regime on subsequent consignments from the same establishment.
Potato starch classified under HS 110813 qualifies as "wholly obtained" when the potatoes are grown and harvested in the EU, satisfying the product-specific rule in Annex ORIG-2 of the EU-UK Trade and Cooperation Agreement. If starch is produced from imported potatoes, the non-originating material must undergo sufficient processing, specifically a change of tariff classification from Chapter 07 (potatoes) to Heading 1108, which is met by the manufacturing process. Denmark, the European number two, had 47.000 hectares of starch potatoes with area stable according to Boerenbusiness. Exporters must ensure the entire production chain from tuber to dried starch occurs within the EU customs territory to claim preferential origin without relying on tolerance rules.
Preferential origin is proven either by an EUR.1 movement certificate issued by EU customs authorities or by a statement on origin made out by the exporter on a commercial document such as the invoice. The statement on origin must replicate the exact wording in Annex ORIG-4 of the TCA, including the exporter's Registered Exporter (REX) number if the consignment value exceeds €6,000. For consignments below €6,000 any EU exporter may issue the statement without a REX number. The EUR.1 remains valid for 10 months from issue date and must be presented to UK customs within that window. UK importers should verify the exporter's REX status via the EU TAXUD database before relying on a statement on origin for high-value loads.
The UK importer claims preferential duty by declaring the preference code "100" in Data Element 1/10 of the Customs Declaration Service (CDS) entry and retaining the proof of origin for six years after the declaration date. HMRC may request the original EUR.1 or a copy of the invoice bearing the statement on origin during a post-clearance audit. If the importer uses a statement on origin, they must also hold evidence that the exporter was approved under the REX system at the time of export. Failure to produce valid proof converts the duty liability to the standard third-country rate of €17.70 per 100 kg for HS 110813 plus potential penalties. Importers should embed origin verification into their supplier onboarding checklist and archive documents electronically linked to the CDS Movement Reference Number.
Retained EU Regulation 2017/2158 sets an acrylamide benchmark level of 400 µg/kg for potato starch placed on the GB market, measured on the product as sold. Food business operators must demonstrate through their HACCP-based mitigation measures that levels are consistently below this benchmark, targeting as low as reasonably achievable (ALARA). Mitigation evidence includes varietal selection of low-reducing-sugar potatoes, controlled storage temperatures above 6 °C, blanching parameters, and drying time-temperature profiles. UK official controls may request the processor's acrylamide monitoring records and sampling plan covering at least one sample per production batch. Exporters should attach the latest accredited laboratory test report (ISO 17025) to the commercial documentation pack to accelerate documentary checks at the BCP.
Great Britain maintains its own MRL statutory register which diverges from the EU database for several active substances relevant to potato production. Glyphosate MRL for potato tubers remains at 0.1 mg/kg in GB while the EU applies a temporary 0.5 mg/kg level pending review. Chlorpropham (CIPC) is not approved in GB and the default MRL of 0.01 mg/kg applies, whereas the EU also sets 0.01 mg/kg but with a different legal basis. Exporters must screen raw potatoes against the GB register published on the HSE website before shipment; any detection above the GB limit renders the consignment non-compliant regardless of EU compliance. Importers should require a pre-shipment multi-residue analysis covering the GB pesticide scope from an ISO 17025 laboratory.
Retained EU Regulation 1881/2006 sets maximum levels for lead at 0.2 mg/kg, cadmium at 0.1 mg/kg, and arsenic at 0.2 mg/kg in potato starch, aligned with current EU limits. Ochratoxin A is not specifically regulated in starch but general food safety obligations require monitoring if risk assessment indicates potential contamination. The UK official feed and food control sampling plan for starch products follows a risk-based frequency: high-risk establishments (previous non-compliance) face increased physical check rates at BCPs while compliant operators typically see documentary checks only. Sampling follows Commission Regulation 401/2006 methods for mycotoxins and Regulation 333/2007 for heavy metals. Exporters should maintain a rolling three-year analytical trend file for each contaminant to demonstrate consistent compliance during UK audits.
Sevington (Ashford) is the primary Border Control Post for plant products arriving via Eurotunnel freight shuttles and handles the highest volume of EU starch shipments with dedicated cold-store and laboratory facilities. Dover operates a plant product BCP at the Western Docks for RoRo traffic but capacity is constrained during peak periods so hauliers should pre-book slots via the GVMS calendar. Eurotunnel's Folkestone terminal processes accompanied and unaccompanied trailers through the same Sevington BCP infrastructure. Hull and Immingham serve LoLo container routes from Rotterdam and Zeebrugge with full plant product inspection capability including sampling bays for starch. Heathrow handles air freight consignments but volumes for potato starch are negligible compared to sea and Channel routes.
For RoRo movements the haulier must create a Goods Movement Reference in GVMS before the vehicle boards the ferry or shuttle linking the CHED-P reference, the customs declaration (MUCR) and the vehicle registration. The GMR is validated at the UK check-in booth and any mismatch triggers a hold at the BCP. For LoLo container moves the shipping line lodges the Entry Summary Declaration and the haulier collects the container using a GVMS-generated GMR only if the container is selected for physical inspection at the port BCP. Hauliers without GVMS registration cannot move goods through RoRo BCPs and must use a registered carrier or freight forwarder to act on their behalf.
The Entry Summary Declaration must be pre-lodged in the UK S&GB system at least one hour before arrival for RoRo and two hours before vessel arrival for LoLo using the 23-data-set dataset including the HS 110813 commodity code and the CHED-P UUID. When starch moves under the Common Transit Convention the transit accompanying document (TAD) or transit/security accompanying document (TSAD) replaces the UK import declaration until the goods reach the authorised consignee's premises or a designated BCP for discharge. The TAD must reference the CHED-P and the guarantor must cover the potential customs duty and VAT liability calculated on the invoice value. Discharging the transit movement at an inland authorised consignee avoids a second BCP presentation but requires an authorised consignee authorisation and a guaranteed transit procedure.
Potato starch entering Northern Ireland from the EU moves under EU SPS rules and requires a CHED-PP (Common Health Entry Document for Plants and Plant Products) pre-notified in TRACES.NI by the NI-based importer or their customs agent at least 24 hours before arrival. The EU health certificate model for starch (COMMISSION IMPLEMENTING REGULATION (EU) 2020/2235) must be issued by the competent authority in the member state of origin and accompany the consignment. No physical BCP checks are applied to EU-origin starch at NI ports such as Belfast or Warrenpoint; the CHED-PP is validated electronically and the goods are released under the standard customs declaration (NI-specific CDS entry) with zero tariff under the EU-UK TCA Rules of Origin.
Upon arrival in Northern Ireland the consignment clears customs through the standard NI CDS declaration using the XI prefix EORI of the NI importer and the EU commodity code 11081300. Revenue NI applies the same zero-duty treatment as the EU provided the Rules of Origin are met and the statement on origin is included on the commercial invoice. Total UK starch exports to the EU were 115 900 tonnes, with Ireland the main importer according to Starch Europe. The absence of SPS checks at NI ports reduces border dwell time to under two hours for accompanied RoRo trailers and same-day release for LoLo containers.
Moving potato starch from Northern Ireland to Great Britain requires the goods to qualify as "qualifying Northern Ireland goods" meaning they must be in free circulation in NI and not have undergone processing beyond minimal operations. The haulier carries the commercial invoice, the original EU health certificate, the CHED-PP printout and the NI customs clearance proof (MRN) as the commercial document pack. No new CHED-P is required for the NI-GB leg but the GB importer must be prepared to present this pack if selected for a risk-based check at the GB inland destination or during a subsequent HMRC audit. Qualifying goods status preserves the zero-tariff benefit and avoids the need for a GB import health certificate.
Organic potato starch entering Great Britain requires a Certificate of Inspection (GB-COI) issued through TRACES-NT by an EU control body recognised by the UK under the EU-UK Trade and Cooperation Agreement. The EU exporter or first consignee must request the COI before the consignment leaves the EU and the GB importer must be registered with a UK organic control body such as Organic Farmers & Growers or Soil Association Certification. Each COI covers a single consignment and must accompany the CHED-P and commercial documents at the Border Control Post. Without a valid GB-COI the consignment loses organic status and can only be placed on the market as conventional starch. The TRACES-NT workflow mirrors the EU import process but uses the GB-specific certificate template and reference numbering series.
Modified potato starch is classified under HS 350510 when the starch has undergone chemical or physical treatment that changes its essential character such as oxidation, esterification, etherification or cross-linking. Native potato starch remains under HS 110813 provided it has not been altered beyond drying, sieving or simple grinding. Customs authorities examine the technical data sheet, production process description and the degree of substitution or viscosity profile to determine the correct heading. Misclassification triggers duty demands and potential penalties because HS 350510 carries a third-country duty rate while native starch qualifies for zero tariff under the TCA. Exporters should obtain a Binding Tariff Information decision from HMRC before the first shipment of a new modified grade.
Native potato starch under HS 110813 enters at zero percent duty when the EU-UK TCA Rules of Origin are met and a statement on origin appears on the commercial invoice. Modified starch under HS 350510 faces the UK Global Tariff most-favoured-nation rate of 7.7 percent ad valorem unless the product-specific rule of origin for heading 3505 is satisfied which typically requires the value of non-originating materials not to exceed 50 percent of the ex-works price. This duty differential makes correct classification and origin documentation critical for landed cost competitiveness. Importers should model both the TCA preferential route and the MFN fallback for each modified grade to avoid unexpected cost spikes at clearance.
The EU exporter engages an Official Veterinarian or Official Certifier to sign the health certificate that supports the CHED-P creation in IPAFFS. Fees vary by member state and certifier but typically range from 50 to 120 euros per consignment for native starch. The CHED-P itself carries no government fee in the UK but the certifier’s time for document review and TRACES notification is billed separately. For organic starch the EU control body charges an additional COI issuance fee of roughly 75 to 150 euros. These costs are usually passed through to the importer as part of the DDP or CIP price and must be budgeted per load rather than per tonne because they are fixed per consignment.
Hauliers apply surcharges when trailers are routed through a Border Control Post instead of the destination depot. A typical BCP diversion adds 80 to 150 euros per load for the extra kilometres and driver waiting time at the inspection hall. GVMS and ENS filing fees charged by the carrier or freight forwarder range from 15 to 30 euros per movement. If the consignment is selected for a documentary or physical SPS check the driver may wait two to six hours incurring hourly detention charges of 40 to 60 euros. Exporters should agree a cap on waiting-time charges in the transport contract and confirm the haulier’s GVMS registration status before loading.
Customs brokerage for a standard starch entry costs 45 to 85 euros per declaration depending on the number of commodity lines and whether the broker handles the CHED-P linkage. If a physical SPS check is triggered the BCP may charge a sampling fee of 120 to 250 euros plus laboratory analysis costs which are invoiced to the importer. Under the TCA native starch attracts zero duty but if origin cannot be proved the MFN rate of zero percent also applies because HS 110813 is duty-free in the UK Global Tariff. Modified starch under HS 350510 faces a 7.7 percent MFN duty which on a 600 euro per tonne CIF value adds 46.20 euros per tonne. EU starch is extracted from 22 million tonnes of EU-grown wheat, maize and starch potatoes according to Starch Europe (2024). This volume context underscores the scale at which per-tonne duty differentials impact total trade value.
The commercial invoice must show the Incoterms 2020 rule and named place of delivery, the HS code 110813 for native potato starch or 350510 for modified starch, and a preferential origin statement referencing the EU-UK TCA when claiming zero duty. Seller and buyer legal names, full addresses, VAT numbers and GB EORI numbers are mandatory. The invoice currency, total value, unit price, quantity in kilograms, and a clear description matching the CHED-P commodity line must be identical across all documents. Any discrepancy triggers a manual customs hold.
The packing list must list gross weight and net weight per pallet and for the full consignment, the exact pallet count, package type such as 25 kg multi-wall paper bags or 1000 kg big bags, and the shipping marks printed on each unit. Container number and tamper-evident seal numbers applied at the EU loading point are required for the GVMS goods movement reference and for BCP verification. If the load is palletised on EUR-pallets the pallet exchange agreement or deposit value should be noted to avoid disputes at the UK delivery depot.
The technical specification sheet accompanies the CHED-P and must display moisture content, pH value, sulphur dioxide residue, Brookfield viscosity at defined concentration and temperature, particle size distribution such as D90 below 100 microns, and the latest acrylamide analysis result in micrograms per kilogram. Results must come from an ISO 17025 accredited laboratory and be no older than six months. Buyers typically require the certificate of analysis to match the lot numbers on the packing list and the CHED-P commodity description.
Successful potato starch export from Europe to the UK hinges on mastering the regulatory split between Great Britain and Northern Ireland, securing zero-duty access through rigorous EU-UK TCA rules of origin proof, and embedding the full SPS checklist into every shipment workflow. Accurate cost modelling that captures certificates, haulage surcharges, brokerage fees, and potential inspection charges prevents margin erosion. Verified buyer due diligence using Companies House, VIES, and credit insurer limits protects cash flow on open-account terms. Treat each consignment as a repeatable process: pre-lodge IPAFFS, confirm GVMS slots, and align haulier ETA with BCP operating hours. This discipline turns market access into a reliable trade lane.
Exporters must secure a GB health certificate (CHED-P) from the EU competent authority, pre-notify the shipment on IPAFFS at least 24 hours before arrival, and provide commercial documents including a preferential origin declaration. The potatoes must be grown and processed in the EU to meet Rules of Origin for zero duty under the TCA.
The core pack comprises the original signed CHED-P, commercial invoice with EORI numbers and origin statement, packing list with batch codes, technical specification sheet showing acrylamide results, and transport documents (CMR or bill of lading) matching the GVMS vehicle declaration.
No single official PDF checklist exists; operators typically build an internal control list covering CHED-P fields, IPAFFS UNN, invoice origin wording, packing list traceability, specification sheet parameters, and CMR/GVMS alignment to present to the haulier and BCP.
Typical logistics range from €40 to €70 per tonne for road transport from Northwest Europe to UK inland depots, plus €15 to €25 per consignment for CHED-P issuance and €5 to €10 per pallet for BCP documentary check fees if selected.
Enter HS 110813 with description "Native potato starch, not chemically modified", the EU establishment approval number (format CC-NNNN), net weight in kilograms, package count, pallet IDs, and attach the signed certificate PDF plus acrylamide report; the transport tab requires vehicle registration, trailer number, BCP of entry, and estimated arrival time.
Yes, a GB-specific Common Health Entry Document for Plants (CHED-P) issued by the EU member state competent authority is mandatory for every consignment of native potato starch entering Great Britain.
The UK Global Tariff code is 1108 13 00 with a third-country duty rate of €17.70 per 100 kg; under the EU-UK TCA the preferential rate is 0% provided the Rules of Origin are satisfied and proven.
Potato starch qualifies as "wholly obtained" if potatoes are grown and harvested in the EU; if non-EU potatoes are used, the manufacturing process must change the tariff classification from Chapter 07 to Heading 1108, which standard starch production achieves.
The retained EU benchmark level is 400 µg/kg for potato starch as sold; food business operators must demonstrate through HACCP-based mitigation that actual levels remain consistently below this threshold.
Key BCPs for plant products include Sevington (Dover), Eurotunnel Folkestone, Purfleet, Tilbury, London Gateway, and Hull; the CHED-P must name the specific BCP of entry and the haulier must book a slot via GVMS using the IPAFFS UNN.
Northern Ireland follows EU SPS rules directly; shipments use TRACES.NI pre-notification and an EU-model health certificate without a CHED-P, moving as intra-EU trade with no BCP checks at Belfast or Warrenpoint.
The EU exporter needs an EU EORI; the GB importer must hold a GB EORI (starting with GB) and be UK VAT registered to clear customs and account for import VAT under postponed accounting.
