Specifications to agree with your supplier
When buying Copper cathode, 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.
