Import 304 Food Grade Stainless Steel Sheet — Buy in wholesale FOB from Supplier in China

The 304 Food Grade Stainless Steel Sheet from Shaanxi Tonghui Steel Co., Ltd is an austenitic cold-rolled or hot-rolled flat product with nominal composition of 18% chromium and 8% nickel, offering the corrosion resistance and formability that make 304 the most widely specified stainless steel in food-contact applications. The supplier lists thickness from 0.15 mm to 3.00 mm for cold-rolled (CR) and 4.00 mm to 200 mm for hot-rolled (HR), with standard widths of 1000 mm, 1219 mm, 1250 mm, 1500 mm, 1800 mm, and 2000 mm, and lengths options including 2000 mm, 2440 mm, 2500 mm, 3000 mm, 3048 mm, and 5800 mm or customised cutting. Surface finishes span No.1, 2D, 2B, BA, No.3, No.4, No.240, No.320, No.400, HL, No.7, No.8, 8K, 6K, polished, and satin, allowing buyers to match exact downstream processing requirements from deep drawing to mirror polishing.

The 304 grade (UNS S30400) stabilises its austenitic microstructure through nickel hotter nickel content rather than titanium or niobium additions, meaning it is not immune to sensitisation if held in the 450-850°C range during welding or subsequent heat treatment. For food-grade service, the critical requirement is surface cleanliness and freedom from sulphide inclusions that could harbour bacterial growth, typically verified by pickling or passivation after any thermal processing. The cold-rolled 2B finish provides a smooth, moderately reflective surface ideal for further polishing or direct use in non-visible equipment, while BA (bright annealed) offers higher reflectivity and reduced surface roughness for decorative food-service items. Hot-rolled No.1 finish is rougher, thicker, and more economical for structural or hidden components where subsequent machining or fabrication will remove the surface.

Buyers for this product include commercial kitchen equipment fabricators producing worktops, sinks, and shelving; dairy and beverage tank manufacturers requiring weldable sheet with certified material traceability; and food processing machinery builders fabricating conveyors, hoppers, and guards. Pharmaceutical packaging equipment makers also specify 304 for contact parts where 316L is not mandated by chloride exposure. Importers should pay particular attention to confirming whether the supplier provides EN 10204 3.1 or 3.2 mill certificates, as food-sector end customers increasingly demand full material traceability and compliance with EC 1935/2004 or FDA 21 CFR for food-contact materials.

Shaanxi Tonghui Steel Co., Ltd is registered at Room 2604, Unit 2, 1st Building of Jinq, Xian, Shaanxi, China, 710086, locating its office in the provincial capital of Shaanxi rather than a primary steel-producing district such as Taiyuan or Shanghai. The company holds a harbor trust tier on its marketplace profile, with a 0.00% response rate and zero recorded average response hours, so buyers should not rely on rapid digital enquiry turnaround. The supplier profile does not list factory ownership, warehouse facilities, processing equipment (slitting, cut-to-length, polishing lines), or annual turnover, meaning the extent of value-added services versus pure trading is unclear without direct inquiry.

The listing describes Shaanxi Tonghui as supplying 304 food grade stainless steel sheet sourced from major mills in Asia for global export, suggesting a trading or distribution model rather than primary mill production. No quality system certifications (ISO 9001, ISO 14001), mill partnerships, or customer references are provided in the source data. Buyers should request evidence of supplier audits, mill authorisation certificates, or long-term supply agreements with recognised producers such as TISCO, Baosteel, or Tsingshan. The custom specification mentions cold-rolled or hot-rolled sheet meeting food safety standards, but does not name the specific standard (GB 4806.9, FDA, or EC 1935/2004), so verification of compliance documentation is a critical pre-order step.
