1. The Commercial Invoice (CI)
This is the primary document used by customs to determine import duties. Ensure the CI clearly states the buyer and seller details, a precise description of the goods, HS codes, unit prices, and total value. Undervaluing goods on the CI is illegal and risks seizure.
2. The Packing List (PL)
The Packing List must match the Commercial Invoice perfectly but focuses on the physical metrics: net weight, gross weight, CBM, and the exact number of cartons. Customs officers use this to verify what is inside the container.
3. The Bill of Lading (B/L)
Issued by the freight carrier, the B/L acts as a receipt for the cargo and the title of ownership. You cannot claim your goods at the destination port without it. Decide whether you need an Original B/L (requires physical mailing) or a Telex Release (electronic).
4. Certificates of Origin (C/O)
Depending on your country's trade agreements with China, a Certificate of Origin (like Form A or Form E) may entitle you to reduced import duties. Request this from your supplier well before shipment, as it requires processing by Chinese authorities.
5. Compliance and Testing Certificates
If your products require specific safety standards (e.g., CE, RoHS, FCC, FDA), ensure the supplier provides the valid test reports from an accredited laboratory. Customs can and will hold shipments if mandatory compliance documents are missing.
