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. Large pipe often ships breakbulk: agree loading and lashing responsibilities.
Quality documents to request
- Mill test certificate (EN 10204 3.1 or 3.2)
- Third-party inspection report
- Certificate of origin (anti-dumping duties often depend on origin)
- Coating and hydrotest reports
