5 Pre-Shipment Checks Every Auto Parts Buyer Should Run Before the Container Leaves China

Match part numbers against the packing list

Ask your supplier to confirm every SKU, quantity and OE/interchange number against the final packing list — line by line, not by carton count alone. A single wrong digit in an OE number can mean a whole carton of filters that fit nothing in your market.

Inspect samples from every carton layer

Damage and mix-ups hide at the bottom of cartons. A proper check pulls samples from the top, middle and bottom of cartons across each product line — filters, cables, clips, wiper blades and brake pads alike. Ask what the sampling rate is, and request photos of the opened cartons.

Check the packaging, not just the product

Export transit is rough. Confirm before loading: sturdy export cartons, sealed and strapped; moisture protection for sea freight; clear carton markings — part number, quantity, and made-in-China origin marking where required.

Weak packaging is the most common cause of arrival damage — and the easiest to prevent.

Verify labels and markings

Labels should match the product inside, in the language your market requires, with no mixed-up barcodes. If you sell under your own brand, confirm the private-label artwork on a sample before the full run is packed.

Get photo and video proof of loading

Before the container doors close, ask for dated photos or a short video of the loaded container: carton stacks, remaining space, and the seal number. This is your evidence if anything arrives short or damaged.
