Import Brake Rotor Disc For Toyota — Buy in wholesale FOB from Supplier in China

Qingdao Long Sun Trading Co., Ltd. supplies a brake rotor disc specifically engineered for Toyota vehicles, identified by part number 43512-12620, manufactured from G300 gray cast iron with pearlitic graphite microstructure. The G300 designation indicates a minimum tensile strength of 300 MPa, suitable for passenger vehicle braking loads where thermal cycling resistance and consistent friction coefficient stability are required. The rotor is positioned as OEM-quality or genuine equivalent, targeting aftermarket distributors and OEM supply chain participants seeking direct replacement compatibility. This listing originates from Shandong province, with the supplier located in Qingdao's Shibei District near port infrastructure.

Pearlitic graphite cast iron G300 contains carbon in flake form within a ferrite-pearlite matrix, providing excellent machinability, vibration damping, and thermal conductivity, properties that make it the dominant material for brake rotor manufacture. The pearlitic structure, as opposed to ferritic, offers higher strength and wear resistance under the compressive loads generated during braking. Surface finish control is critical for this application: the friction interface must present sufficient texture for pad bedding without excessive roughness that accelerates pad wear or generates noise. The listing emphasises wear resistance and silent operation, suggesting attention to surface topography and potentially slot or hole patterns for gas and dust evacuation, though these features are not explicitly described.

The stated application is Toyota vehicle models with this specific part number cross-reference, though the exact model years and chassis codes are not listed. B2B importers, wholesalers, and auto parts distributors form the target market, with the supplier indicating suitability for both global aftermarket and OEM supply chain integration. Buyers should verify whether the supplier holds a licence agreement with Toyota or operates as an independent aftermarket manufacturer. The OEM-quality claim requires substantiation through dimensional inspection reports and material certificates, which the buyer must request directly from Qingdao Long Sun Trading Co., Ltd.

Qingdao Long Sun Trading Co., Ltd. is based at Haian Road No. 2, Shibei District, Qingdao, Shandong, China, a location with direct access to Qingdao Port, one of China's major container shipping hubs for automotive parts exports. The company holds a harbor trust tier with a 0.00% response rate and zero recorded average response hours, indicating no platform-mediated communication history. Buyers should not interpret this as negative verification but rather as an absence of data, requiring direct outreach to assess technical competence and responsiveness.

The supplier operates as a trading company rather than a direct manufacturer, based on the company name structure. This distinction matters for quality accountability: trading companies may source from multiple foundries, creating batch-to-batch variation risk. The listing provides no information about manufacturing partner audits, production capacity, years in operation, or employee count. Importers should request the actual manufacturer's name and address, factory audit reports, and evidence of long-term supply agreements. The material specification G300 gray cast iron suggests technical familiarity, but buyers must verify whether the supplier employs metallurgical expertise or relies on factory-provided certificates without independent validation.
