Tangshan Yingtu Trading Co., Ltd.

China‑based Tangshan Yingtu Trading Co., Ltd. lists 31 active trailer‑related products in its catalogue. The items span electric and hydraulic brake assemblies, axle and hub components, leaf springs, and various drum and brake hardware, with several entries explicitly coded under HS 8708.30, 8708.39, 8708.40 and 8708.83 for motor‑vehicle parts. Each product description references standard dimensions - for example 10 × 2‑1/4 inches electric brakes or 12 inches hydraulic brake units - and material specifications such as steel housings, cast‑iron drums or Dacromet‑coated steel. The catalogue also includes specialty items like self‑adjusting electric brakes, override brake couplings and triple‑axle assemblies, reflecting a focus on aftermarket trailer repair and retrofit markets. The supplier’s catalogue groups products by function: brake assemblies (electric, hydraulic, self‑adjusting), brake drums and hubs (various stud patterns), axle spindles and torsion axles, and supporting components such as leaf springs and bearing kits. Where HS codes are supplied, they align with the global HS chapter 87 for vehicle parts, indicating that shipments are treated as automotive components rather than general steel goods. This structure enables buyers to locate specific trailer‑brake solutions quickly and to match them with the appropriate customs classification for import.

Tangshan Yingtu’s product list covers electric brake assemblies ranging from 7 in to 12 in diameters, hydraulic uni‑servo brakes with Dacromet coating, and cast‑iron disc‑caliper units. In the trailer‑brake market, electric brakes are commonly rated by torque output (e.g., 5‑10 Nm) and must meet ECE R90 performance standards, while hydraulic brakes are evaluated for hydraulic pressure (typically 5‑10 bar) and wear resistance. Standard drum specifications include a 6‑bolt or 5½‑inch stud pattern, a bore size that matches common hub diameters, and a minimum cast‑iron hardness of 180 HB. Leaf springs are usually graded by load capacity (e.g., 2,500 lb to 3,500 lb) and spring rate measured in N/mm. Industry practice for trailer parts from China includes offering ISO 9001 quality‑management certification, CE marking for the European market, and compliance with ASTM A108 for forged steel components. Buyers often request material test reports confirming tensile strength (≥ 450 MPa for steel housings) and coating thickness (≥ 30 µm for Dacromet). The catalogue’s mix of steel, cast iron and zinc‑flake coated parts reflects the typical material palette used to balance durability, weight and corrosion resistance in trailer applications.
