Question 1

How do I distinguish between sorted and mixed LDPE scrap when the listing is vague?

Accepted Answer

Mixed LDPE scrap contains various polyethylene types and colors, requiring more extensive washing and separation at your facility. Sorted LDPE is pre-segregated, usually by color or resin code, reducing your processing costs. Ask the seller for a detailed breakdown of the composition percentages to determine if the lower purchase price offsets the higher processing effort.

Question 2

What happens if OCC waste paper contains too much moisture or non-paper content?

Accepted Answer

High moisture content increases shipping weight without adding value, leading to penalties from buyers or customs. Excessive non-paper contaminants like plastic or wood can cause processing jams at recycling plants. Ensure the listing specifies the moisture percentage and contaminant limits, as these factors directly impact the net tonnage you receive.

Question 3

Why does sourcing PU foam scrap from a landlocked country involve extra transit steps?

Accepted Answer

Since Paraguay has no direct ocean access, PU foam scrap must be trucked to ports in Brazil or Uruguay. This additional overland leg introduces handling risks and delays that coastal exporters avoid. You must factor in the transit time and potential for compression or damage during the road haul when planning your inventory.

Question 4

How does the sub-category choice affect the inspection requirements for scrap materials?

Accepted Answer

Agriculture scrap often requires phytosanitary certificates to prove it is free from pests and soil. Industrial or construction scrap may need chemical safety declarations or heavy metal testing. Choosing the wrong sub-category can lead to missing critical documentation, causing delays at the destination border or rejection of the shipment upon arrival.

Question 5

What specific packing format is required for baled OCC waste paper to survive transit?

Accepted Answer

OCC waste paper must be tightly baled and wrapped in weather-resistant material to prevent rain damage during overland transit. Loose bales are prone to shifting and tearing, which exposes the paper to moisture. Confirm that the seller uses high-density baling and waterproof wrapping to maintain the material's quality throughout the journey to the port.

Question 6

Why might a listing for furniture foam scrap lack specific density or flame retardancy details?

Accepted Answer

Many sellers list PU foam scrap without specifying density or chemical treatments, assuming the buyer will verify these later. However, density affects the yield during recycling, and flame retardancy determines regulatory compliance in your market. Always request a technical data sheet before agreeing to a price, as these specs are not always visible in the initial listing.

Question 7

How do customs declarations differ for mixed plastic scrap versus sorted plastic scrap?

Accepted Answer

Mixed plastic scrap often faces stricter import controls due to the difficulty in identifying specific polymer types. Sorted plastic scrap, with clear resin codes, is easier to classify and may face fewer regulatory hurdles. Misclassifying mixed scrap can lead to customs holds, fines, or the requirement for expensive on-site testing before the goods can clear.
