About Sinya International Trade Co., Ltd - Agriculture Supplier in China
Sinya International Trade Co., Ltd operates out of China and currently lists five active products in its catalogue. The company is classified as an imported supplier with a harbor trust tier, indicating a moderate level of verification by trade platforms. Its product portfolio includes items that fall under industrial safety and metalworking equipment, rather than traditional agricultural goods. The catalogue entries are limited to product names without detailed specifications, HS codes, or declared certifications. Buyers can locate these five items under the single top‑level category of Agriculture as reported in the source data.
Product Range and Specialties of Sinya International Trade Co., Ltd
The listed items comprise a safety helmet, mill rolls, casting grinding balls, centrifugal casting rolls, and a copper mould tube. Safety helmets for construction and manufacturing typically conform to standards such as ANSI Z89.1 or EN 397 and are made from high‑density polyethylene or polycarbonate with a weight of 1.0‑1.5 kg. Mill rolls used in rolling mills are usually forged carbon steel or alloy steel, hardened to a Brinell hardness of 250‑350 HB and supplied in lengths of 1 m to 2 m. Casting grinding balls are steel balls graded by hardness (e.g., 45 HRC, 55 HRC) and size range from 5 mm to 30 mm, often supplied in bulk bags of 20 kg. Centrifugal casting rolls and copper mould tubes are components for casting processes, generally fabricated from high‑strength steel or copper‑nickel alloys, with dimensions customized to the caster’s requirements.
Trade and Export Information - Sinya International Trade Co., Ltd
China remains a major exporter of industrial safety gear and metalworking components, shipping to regions such as Southeast Asia, the Middle East, Europe and North America. Products like safety helmets and grinding media are classified under HS chapters 65 and 73 respectively, and buyers commonly request CE marking, ISO 9001 quality management certificates, and material test reports. Export logistics for these items usually involve containerised shipments in 20‑ft or 40‑ft units, with standard packaging of cardboard boxes or wooden crates, and Incoterms such as FOB Shanghai or CIF Hong Kong. Import regulations often require conformity to local occupational safety standards and, for metal products, compliance with REACH or RoHS where applicable. Typical importers include construction firms, automotive parts manufacturers, and metal‑processing plants that need reliable, specification‑driven components.
Sourcing from Sinya International Trade Co., Ltd - Buyer Guidance
When sourcing from Sinya International Trade Co., Ltd, buyers should request the specific safety standard certificates for helmets (e.g., ANSI Z89.1 test report) and material certification for metal parts (e.g., mill test certificates, hardness reports). For grinding balls and casting rolls, ask for grade identification, size distribution tables, and chemical composition analysis to confirm compliance with industry grades such as 45 HRC or 55 HRC. Verify that the supplier can provide ISO 9001 or equivalent quality system documentation before placing a purchase order. Clarify minimum order quantities, lead times for tooling or custom dimensions, and preferred packaging (e.g., bulk bags for balls, wooden pallets for rolls) to align with logistics planning.
