The price differences you observe are usually not simply a matter of "selling low and high," but are determined by multiple real cost factors.

Some suppliers attract orders with low prices first, then add costs in the following ways:
Ocean Freight Surcharges: The quoted price may be FOB, but a higher-priced freight forwarder is specified, or the buyer is passed on the increased freight costs.

Destination Port Charges: Low invoices lead to customs clearance problems, or unprofessional customs declarations result in penalties.

Order Amendment/Expedited Delivery Fees: During the later stages of production, suppliers demand additional fees to ensure timely delivery under the pretext of "rising raw material prices" or "environmental protection restrictions."
Document Discrepancies: Deliberately creating discrepancies to delay payment or demand price reductions.

Don't just look at the unit price. Request the following from the supplier:
Based on the material (specific grade, standard), whether VAT is included, packaging details (photos or videos), payment method and prepayment percentage, supporting documentation for claims in case of quality issues or delays.

Price differences among Chinese suppliers are a normal market phenomenon; the key is to understand the value behind the price. We recommend that you prioritize suppliers with reasonable prices, transparent pricing breakdowns, and the willingness to accept third-party verification.
