H4 Fixring
The H4 fixring supplied by Zhejiang Invitech Precision Technology Co., Ltd is a stainless‑steel adapter that anchors H4 headlamp bulbs in Korean‑specification lighting assemblies. According to the listing, the component is machined from SUS 430 stainless steel and features a height of 2 mm with a tolerance of ±0.2 mm, an outside diameter of 25.2 mm ±0.2 mm and an inside diameter of 24.05 mm ±0.1 mm. Two additional ventilation holes are incorporated to improve heat dissipation, and the part complies with the VDA 6.3 audit and IATF 16949 certification. Packaging is supplied as 5,000 pieces per carton, and the listed FOB term is Shanghai.
SUS 430 is a ferritic stainless steel commonly used for automotive lighting components because of its typical corrosion resistance and cost‑effectiveness. The dimensional tolerances of ±0.2 mm for height and diameter are within standard limits for precision stamped lamp adapters, ensuring consistent bulb seating. The extra ventilation holes are a design adaptation that aligns with Korean market requirements for enhanced thermal management, a typical solution for high‑power H4 bulbs that can generate up to 60 W of heat. Production employs progressive die stamping, a standard high‑speed method for achieving tight tolerances in large volumes.
The fixring is primarily targeted at OEMs and aftermarket distributors supplying replacement parts for Korean vehicle models such as Hyundai and Kia. Importers should verify the component’s compatibility with the specific vehicle’s headlamp housing, especially the inner diameter of 24.05 mm, before confirming an order. While the supplier states a minimum order of 50,000 pieces, exact lead times and payment conditions must be negotiated, with FOB Shanghai being the default shipping term. Buyers may also request custom packaging or OEM branding if required for their market.

Sourcing H4 Fixring from Zhejiang Invitech Precision Technology Co., Ltd - China Import Guide
Importers should first obtain the material test report confirming the SUS 430 composition and request the VDA 6.3 and IATF 16949 audit certificates to validate the supplier’s quality system. The technical drawing that details the height, outside and inside diameters, as well as the location of the ventilation holes, should be reviewed to ensure compatibility with the target vehicle’s headlamp housing. A pre‑shipment sample inspected for dimensional accuracy and surface finish can prevent costly re‑work.
The standard shipping arrangement for the fixring is FOB Shanghai, but buyers must confirm the exact incoterm and arrange sea freight to their destination port. Lead times depend on the order volume and mould availability; therefore, discuss production scheduling and any required tooling lead time with the supplier. Payment terms are typically negotiated as a bank transfer deposit followed by balance against documents, but the precise arrangement should be agreed in the contract.
