About Qingdao Jasper Inernational Trading Co., Ltd. - Automobile Bolts, Nuts, Springs & Bearings Supplier in China

Qingdao Jasper Inernational Trading Co., Ltd. is based in China and currently lists five active products. The catalogue focuses on automotive suspension components, specifically three series of leaf springs - Uk dai, Siertai and Man - plus a Faw Jiefang J6 series leaf spring and a line of transverse stabilizer bars. These items fall under the broader category of automobile bolts, nuts, springs and bearings as well as truck and four‑wheeler spare parts. The supplier’s catalogue does not provide HS code numbers, but the products correspond to the typical HS chapter 73 families for metal springs and bars. All five items are presented without additional accessories or ancillary hardware.

The product list consists solely of leaf spring models and a stabilizer bar, indicating a specialization in chassis suspension hardware. Leaf springs are generally classified under HS code 7318.10 (spring steel products) while stabilizer bars are often covered by HS code 7308.92 (metal bars). No other component categories such as bolts or nuts appear in the current offering, so the supplier’s active range is narrowly focused on these suspension parts.

Product Range and Specialties of Qingdao Jasper Inernational Trading Co., Ltd.

The catalogue includes three distinct leaf‑spring series - Uk dai, Siertai and Man - each typically manufactured from high‑carbon spring steel meeting SAE grades 65, 80 or 100. Industry practice specifies heat‑treated steel with a tensile strength of 1,600‑2,000 MPa, a yield strength of 1,200‑1,500 MPa, and a hardness of 30‑35 HRC. Common dimensions for passenger‑car leaf springs range from 1.0 m to 1.5 m in length, 30‑50 mm in width, and thicknesses of 2‑4 mm, with load capacities from 500 kg to 1,500 kg per leaf. Transverse stabilizer bars are usually fabricated from cold‑drawn steel or alloy steel, with diameters between 20 mm and 35 mm and a typical torsional rigidity of 1,200‑2,500 Nm/deg. Buyers often request specifications such as overall length, eye‑hole spacing, and spring rate (N/mm).

Trade and Export Information - Qingdao Jasper Inernational Trading Co., Ltd.

China is a leading exporter of automotive suspension components, supplying Europe, North America and Southeast Asian markets. Leaf springs and stabilizer bars are shipped in 20‑foot containers, typically packed in wooden crates with protective film to prevent corrosion. The HS‑code families most relevant are 7318 (spring steel products) and 7308 (bars, rods, angles). Importers frequently require ISO 9001 quality‑management certification, ISO/TS 16949 for automotive suppliers, and CE marking for EU entry, although the supplier’s own certifications are not listed. Standard Incoterms used for these goods include FOB Qingdao port or CIF to the buyer’s destination, with load‑bearing pallets designed for 1,200 kg per pallet.

Sourcing from Qingdao Jasper Inernational Trading Co., Ltd. - Buyer Guidance

When sourcing leaf springs or stabilizer bars, request a Material Test Report (MTR) confirming chemical composition, tensile strength and hardness. Verify dimensions, eye‑hole spacing and spring rate against the buyer’s vehicle specifications, and ask for compliance documentation such as SAE J119 for leaf springs or ISO‑specific test certificates for stabilizer bars. Typical minimum order quantities in the industry range from 500 to 1,000 units, with lead times of 30‑45 days after order confirmation, subject to material availability. Sampling is commonly offered in single‑unit or small‑batch form, allowing verification of finish, straightness and mechanical performance before larger orders are placed.
