Export Documents Explained: COA, SDS, Third-Party Inspection

Bitumen is bought on trust in documents long before it is seen on site. These are the documents that matter in an export shipment from China, and what each one actually proves.

Certificate of Analysis (COA)

The COA reports the test results of the shipped batch — penetration, softening point, ductility, flash point and the other items in the grade specification — measured by the producer or exporter laboratory. Check three things: the batch/lot reference matches your packing list, the test methods match your specification (ASTM, EN or JTG), and every value sits inside the specified range, not just near it.

Safety Data Sheet (SDS)

The SDS describes hazards, handling, storage and first-aid for the product. Shipping lines and destination customs may request it, and your site safety file needs it — hot bitumen burns are the main hazard it covers. Keep the SDS with the shipment file and brief your site team from it.

Third-party inspection

An inspection company (commonly SGS or BV) can witness sampling and testing, verify quantity and supervise container loading and sealing. It costs a fee and a day of schedule, and for first orders or large project supply it is money well spent: the report is independent evidence both sides can rely on.

The rest of the file

Commercial invoice, packing list (with drum/bag counts and net weights), bill of lading and, where required, a certificate of origin complete the standard set. Before the vessel sails, reconcile names, weights and container numbers across all documents — most customs delays are clerical, and they are avoidable.

We issue the COA and SDS with every shipment and can arrange third-party inspection on request — mention it in your inquiry so it is built into the quotation.
