What customs data cannot confirm
Shipment counts, buyers and recency show trade activity only. They do not verify product quality, certifications, production capacity, minimum order quantities, pricing, lead times, or whether a company will take on a new buyer. Use the evidence to shortlist, then verify directly. Nor do they state whether a company sells wholesale or holds stock today.
