Import Brake Lining, Brake Pad, Greening Test,4644 — Buy in wholesale FOB from Supplier in China

Tough Pro Group Limited, based in Huangshan, Anhui Province, manufactures brake linings and brake pads engineered to FMSI (Friction Materials Standards Institute) dimensional and performance benchmarks for aftermarket automotive and heavy-duty applications. The product line referenced as "4644" indicates a specific FMSI-formulated compound designation, with the greening test protocol verifying that friction materials meet environmental emissions criteria during the bedding-in phase. The supplier lists ISO and CE compliance as part of their quality framework, though buyers should request current certificate validity directly.

The friction material typically consists of a bonded composite matrix: organic fibres (aramid, glass, or mineral wool), metallic fillers (copper, brass, or steel fibres for heat conductivity), and phenolic resin binders cured under controlled temperature and pressure. The "greening test" referenced in the product name denotes a controlled bedding procedure that measures coefficient of friction stability, fade resistance, and rotor compatibility during initial break-in cycles. Standard industry practice requires a friction coefficient between 0.35 and 0.45 for passenger vehicles and 0.40 to 0.55 for commercial applications, with wear rates typically evaluated per SAE J661 or AK-Master test protocols.

Primary buyers include automotive aftermarket distributors, commercial vehicle fleet operators, and brake system rebuilders sourcing replacement friction components for drum and disc brake configurations. The Huangshan location positions the supplier within Anhui Province's manufacturing corridor, with access to Ningbo or Shanghai port logistics for export consolidation. Buyers should confirm current MOQ flexibility, validate FMSI-4644 compound-specific test data, and specify packaging requirements for moisture-sensitive friction materials prior to order placement.

Tough Pro Group Limited operates from 82 Baichuan Road in Huangshan Economic Development Zone, Anhui Province, China, a region with established automotive component manufacturing infrastructure. The supplier holds a 'harbor' trust tier classification on the marketplace platform, which indicates a baseline verification level rather than advanced supplier auditing. Notably, the response rate is recorded at 0.00 percent with zero average response hours, signalling that direct communication channels may be unmonitored or that the supplier prefers offline negotiation through alternative contact methods.

The company profile does not disclose manufacturing floor space, employee count, annual turnover, or specific OEM client relationships, so any such claims would be speculative. What the listing does indicate is a focus on FMSI-standard brake friction materials with environmental testing protocols and flexible order quantities. Buyers should conduct independent verification of factory credentials, request sample test reports for the 4644 compound, and establish direct communication before committing to volume orders given the unresponsive platform messaging status.
