Guidance only. The exact 6- to 10-digit code depends on the product and the importing country's tariff. Confirm with your customs broker.
Incoterms tips
For containerised goods, FCA, CPT or CIP are usually a better fit than FOB/CIF, because the seller hands over at a terminal or warehouse rather than over the ship's rail. Use DAP or DDP only if the seller can really handle delivery (and, for DDP, import clearance) in your country.
Quality documents to request
- COA
- SDS
- Technical data sheet
- End-use declaration
- Spent-catalyst return or recycling terms where relevant
