Specifications to agree with your supplier
When buying PET chips, agree in writing on the grade, applicable standard, packaging, delivery term (Incoterm) and acceptance criteria. Ask for a certificate of analysis (COA) for every lot, the technical data sheet (TDS) and, where relevant, the safety data sheet (SDS).
How to source reliably
Work with verified (KYC) suppliers, request samples and a trial lot before large volumes, use independent inspection (SGS, Bureau Veritas, etc.) and tie payment terms to shipping milestones. The platform deal room keeps offer history, the digital contract and delivery steps on record in one place.
Transport, storage & customs
Customs usually classify PET chips under HS heading 3907.61; always confirm the exact code in your importing country’s tariff. Store the goods dry, protected from moisture and direct sunlight with packaging intact, and ask for loading photos and the bill of lading (B/L) before shipment.
