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.

CSMC's self-operated products all use a clearly broken-down pricing method. If you purchase through our platform, we will ensure that you receive the actual product matching the quoted price.

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.

The gross and net weights of stainless steel plates are not fixed values, but depend on the actual weight of the specific plate, the packaging method, and the calculation method.

The theoretical weight of a stainless steel sheet is calculated based on the nominal dimensions and density (formerly known as specific gravity) of the steel. This is directly related to the length, cross-sectional area, and dimensional tolerances of the steel. Due to allowable deviations during the manufacturing process, the theoretical weight calculated using the formula will differ slightly from the actual weight, and therefore should only be used as a reference for estimation.

1. Gross weight is the counterpart to "net weight," and it is the total weight of the steel itself and the packaging materials. Transportation companies calculate freight charges based on gross weight. However, in steel sales, net weight is used.

2. Net weight is the counterpart to "gross weight." It is the weight of the steel after subtracting the weight of the packaging materials from the gross weight of the steel, i.e., the actual weight, and is generally calculated based on net weight in steel sales.

3. Tare weight is the weight of the steel and its packaging materials.

2B stainless steel sheet is actually a matte-finish sheet material produced by cold rolling, annealing, pickling, and then precision rolling. This process gives the sheet a smooth and uniform surface, with a slight reflective quality like frosted glass, retaining the metallic texture while being more scratch-resistant than mirror-finish sheets.
2B stainless steel sheets are generally less than 3mm thick, although 5mm, 6mm, and 8mm thick (very rare) 2B sheets are also available. 2B stainless steel sheets are typically used in applications requiring a specific surface finish.
