Product Range and Specialties of Zhejiang Invitech Precision Technology Co., Ltd

Metal stamping and deep drawing in China commonly employ carbon steel, stainless steel grades 304, 316 and 430, and aluminium alloys such as 6061‑T6, with tolerances often held to ±0.05 mm and surface roughness Ra 0.8 µm for automotive‑grade parts. Typical HS code 7326.90 covers stamped metal products, while 7415.39 is used for brass and copper alloy insert mouldings, and 7604.29 for aluminium deep‑drawn items. Buyers usually request material certificates complying with ASTM A240 (stainless steel) or EN 573 (aluminium), as well as hardness tests (Rockwell B 80‑100 for stainless steel). For precision dies made from engineering plastics, HS 3926.90 applies and the material is often an ABS/PA66 blend meeting UL 94 V‑0 flame‑retardant rating. The supplier’s listed parts such as Precision Metal Stamping Parts and Metal Insert Molding Parts align with these industry specifications. Automotive and general lighting fittings such as H4 Bulb Holders, H4 Car Lamp Bases and various adjustment rings are classified under HS 8536.29 and 8539.90, categories that typically require compliance with IEC 60061 and RoHS restrictions on lead and cadmium. Standard material selections include stainless steel SUS 202 or 430 for structural strength and nickel‑plated brass for corrosion resistance, with dimensional tolerances of ±0.03 mm for socket threads. Test reports often include electrical continuity, insulation resistance, and temperature rise under IEC 60598 testing. Injection‑moulded PVC components, while not assigned an HS code in the catalogue, are generally covered by HS 3926.90 and must meet UL 94 V‑0 or V‑1 flammability grades. These specifications are typical for suppliers serving OEMs in the automotive lighting market in Europe and North America.

Trade and Export Information - Zhejiang Invitech Precision Technology Co., Ltd

China is one of the world’s largest exporters of machined components, metal stamping parts and automotive lighting fittings, with the majority of shipments destined for Europe, North America, Southeast Asia and the Middle East. Products classified under HS 7326.90, 7415.39, 7604.29, 8536.29 and 8539.90 are routinely inspected by Chinese customs (CIQ) and often require third‑party verification such as SGS or BV certificates before loading. Common buyer‑required certifications for these categories include ISO 9001 quality management, ISO/TS 16949 for automotive‑related parts, RoHS compliance, CE marking for electrical components, and material test reports according to ASTM or EN standards. Export logistics typically involve palletized loads on 20‑ft or 40‑ft containers, with FOB or CIF terms prevailing in B2B contracts. Given the supplier’s harbor‑tier trust level, buyers can expect the company to be listed in the port‑authority verified supplier registry, which facilitates smoother customs clearance. Machined and stamped metal parts are usually packaged in anti‑corrosion paper or polymer film and placed in wooden crates with internal bracing to prevent deformation. Lighting and socket components are often shipped in sealed cardboard boxes with moisture‑absorbing packets to meet IEC humidity requirements. Importing countries frequently request pre‑shipment inspection reports (PSI) and a certificate of origin to qualify for preferential tariffs under various trade agreements. Buyers in the automotive sector typically integrate these components into chassis, lighting assemblies and interior trim, while electronics manufacturers use the plastic dies for enclosure production. Overall, the combination of HS‑code alignment, standard certifications and established logistics channels supports reliable cross‑border trade for this product mix.

Sourcing from Zhejiang Invitech Precision Technology Co., Ltd - Buyer Guidance

When sourcing metal stamping or deep‑drawn parts from this supplier, request material test certificates (MTC) that reference the exact steel grade (e.g., ASTM A240 for SS 304) or aluminium alloy standard (e.g., EN 485 for 6061‑T6). Ask for dimensional inspection reports showing compliance with the specified tolerances and surface finish, and verify that the parts have undergone hardness testing (Rockwell B/HB) as appropriate. For lighting fixtures and socket components, obtain RoHS compliance statements, CE conformity declarations and electrical safety test reports according to IEC 60598 and IEC 60061. If the catalogue entries lack HS codes, confirm the correct classification before shipment to avoid customs delays. Typical minimum order quantities for stamped metal parts range from 500 to 1,000 pieces, with lead times of 4 - 6 weeks after final artwork or drawing approval. Request a physical sample or a 3‑D CAD file for each new part type to validate fit, finish and functional performance before committing to full production. Confirm that the supplier can provide a pre‑shipment inspection report issued by an accredited third party such as SGS, especially for high‑value automotive or lighting items. Clarify packaging requirements - e.g., wooden crates with internal padding for large stamped components or moisture‑controlled cartons for electrical parts - to align with your receiving facility standards. Verify the supplier’s ability to issue a certificate of origin and, where applicable, a free‑sale certificate to satisfy import regulations. Maintain clear communication on Incoterms (FOB or CIF) and shipping schedules to coordinate customs brokerage and warehouse planning.
