On-Site Verification Services
Independent verification support before shipment for battery buyers sourcing from China.
Reduce Sourcing Risk Before Shipment
Battery sourcing risk often appears late in the project: model mismatch, mixed batches, unclear labels, incomplete shipment documents, or records that do not support traceability. Thirteentrading provides on-site verification support to help overseas buyers review key shipment and supplier information before goods leave the factory.
We are not a testing laboratory and we do not replace accredited certification or full performance testing. Our role is to support practical, independent review of shipment information, traceability records, OQC evidence and commercial documents.

Important Notice
Verification services help reduce sourcing risks by improving visibility before shipment. No service can guarantee the elimination of all risks, and verification support should be used together with supplier qualification, clear purchase specifications and appropriate third-party testing where required.
