The H4 G16T car lamp base is a precision‑engineered socket designed to secure H4 headlamp bulbs in automotive lighting assemblies. It is fabricated from stainless steel SUS 43, equivalent to AISI 430, providing corrosion resistance and thermal stability. The component conforms to HS Code 853990 and is supplied in individual cartons with optional OEM branding. The base dimensions follow the standard H4 thread profile (M14 × 1.5 mm) as typical for the sector. The supplier lists the material and packaging but does not disclose a fixed MOQ or price, so buyers should confirm those details directly.
SUS 43 offers a typical tensile strength of around 480 MPa and a typical operating temperature range from - 40 °C to +150 °C, matching automotive lighting requirements. The base is compatible with both 55 W and 60 W H4 bulbs, a standard rating for most passenger vehicles. Visual inspection is performed on 100 % of units using automated equipment to achieve a zero‑defect target. The manufacturing facility employs progressive die stamping and CNC machining, typical processes for high‑precision lamp components. The design includes a smooth finish to aid heat dissipation, a common industry practice.
Primary users are OEM lighting manufacturers and aftermarket spare‑parts distributors supplying to global markets. The product is suitable for integration into headlamp assemblies for cars sold in Europe, North America and Asia. Buyers should request FOB Shanghai terms and verify the supplier’s VDA 6.3 audit status. Packaging of one base per carton facilitates handling, while bulk orders can be coordinated with the supplier’s logistics team. Confirmation of lead time and payment conditions is required before placing an order.

Before placing an order for the H4 car lamp base, importers should obtain the supplier’s material certification confirming the SUS 43 grade, request the latest VDA 6.3 audit report, and verify the technical drawing that shows thread dimensions and tolerances. Comparing the supplier’s sample with the buyer’s own specifications helps ensure fitment with existing headlamp assemblies. Any deviation in material composition or dimensional tolerance can affect bulb sealing and heat management, so a pre‑shipment sample is advisable.
The typical shipment route for products from Zhejiang Invitech is via the port of Shanghai under FOB terms, but the exact incoterm must be agreed with the supplier. Importers should confirm the lead time for tooling and production, which may vary with order size, and negotiate payment conditions such as a 30 % deposit by T/T followed by balance against a clean Bill of Lading. Freight forwarders familiar with Chinese automotive parts can arrange container loading, taking into account the carton packaging of each base.
Upon arrival, buyers should conduct a random inspection of at least 5 % of the units, checking for visual defects, correct thread profile, and corrosion resistance using a salt‑spray test if required. Request the supplier’s inspection certificates and a test report for dimensional compliance. Retaining a copy of the supplier’s quality control plan can aid in resolving any non‑conformities and supports future audits of the supply chain.
