About PT Wira Karya Sempurna - Car Parts Supplier in Indonesia

Indonesia, a major hub for automotive component manufacturing, hosts PT Wira Karya Sempurna which lists nine active products in its catalogue. The supplier’s active product count of nine covers a variety of automobile spare parts, including suspension components, brake assemblies, engine accessories and rubber items. Each product is classified under the automotive parts HS chapters, with two items explicitly linked to HS codes in the catalogue. The company is positioned in the “harbor” trust tier, indicating a moderate level of verified trade activity.

The catalogue details suspension parts listed under HS 8708.99 and described as carbon steel or alloy steel with zinc or phosphate coating. Brake parts appear under HS 8708.39 and are made from carbon steel or spring steel that undergoes heat treatment. Additional entries include generic bolts and nuts, engine parts, hoses, spare‑tire carriers, pipes, rare parts and rubber parts, all falling within the broader Car Parts and Automobile Spare Parts categories. Material specifications are limited to the steel families and rubber mentioned, without further grade or certification data.

Product Range and Specialties of PT Wira Karya Sempurna

The suspension parts offered are fabricated from carbon or alloy steel, a material commonly supplied to meet ASTM A572 or EN 10210 specifications for automotive chassis components. Zinc or phosphate coating is typical for corrosion protection, with industry practice targeting a coating thickness of 5‑10 µm and a minimum adhesion strength of 10 MPa. Brake components made from carbon or spring steel generally conform to ISO 6303 or DIN 17253 standards, with heat‑treated hardness in the range of 45‑55 HRC for reliable friction performance. Bolts and nuts are usually produced to DIN 933, DIN 934 or ISO 4014/4017 dimensions, with tensile strength classes ranging from 8.8 to 12.9 depending on the application. Rubber parts such as hoses and seals are frequently based on natural or synthetic rubber compounds meeting ISO 3302 or BS 1928 specifications for oil and temperature resistance.

Typical automotive spare parts from Indonesia are supplied in bulk packs, wooden crates or reinforced cardboard, sized for 20‑foot or 40‑foot containers. Buyers often request material test reports, coating thickness measurements, hardness profiles and dimensional inspection certificates to verify compliance with the above standards. While PT Wira Karya Sempurna does not list specific certifications, industry buyers normally ask for ISO 9001, ISO/TS 16949 or equivalent quality system certificates for steel components, and for REACH or RoHS compliance documentation for rubber items.

Trade and Export Information - PT Wira Karya Sempurna

Indonesia exports automotive components primarily to Southeast Asian markets, East Asian manufacturers, European vehicle assemblers and North American OEMs. The HS 8708.99 and HS 8708.39 families encompass a broad selection of suspension and brake parts, which are routinely inspected under customs regulations that reference the Harmonized System and the ASEAN‑China Free Trade Area tariff schedules. Common buyer requirements include ISO 9001 or ISO/TS 16949 quality management certification, CE marking for EU shipments, and compliance with the United Nations Convention on Contracts for the International Sale of Goods (CISG). Packaging for steel parts typically follows ISPM 15‑compliant wood treatment for pallets, while rubber items are packed in moisture‑controlled bags to prevent degradation during sea transit.

Logistics norms for Indonesian automotive parts favour FOB or CIF Incoterms, with loading on container ships from Jakarta or Surabaya ports. Container loading efficiency is enhanced by stacking steel components on wooden dunnage, achieving up to 18 tons in a 20‑foot container or 24 tons in a 40‑foot container. Buyers should anticipate inspection by the Indonesian National Agency of Drug and Food Control (BPOM) for any chemically treated rubber, and possible phytosanitary checks for wooden packaging before export.

Sourcing from PT Wira Karya Sempurna - Buyer Guidance

When evaluating PT Wira Karya Sempurna, buyers should request mill test reports for carbon and alloy steel, specifying chemical composition, tensile strength and impact energy values. Coating verification reports should detail zinc or phosphate layer thickness, surface roughness and adhesion test results. For brake parts, heat‑treatment certificates that include hardness distribution (measured in HRC) are standard. Rubber hoses and seals should be accompanied by compound data sheets showing compliance with ISO 3302, REACH registration status and oil‑resistance test outcomes.

Buyers are advised to confirm the supplier’s quality management system certification - ISO 9001 or ISO/TS 16949 - before placing large orders. Sample requests for critical components such as suspension brackets or brake calipers should include at‑least three units for dimensional inspection and functional testing. Typical minimum order quantities range from 500 to 1 000 units per SKU, with lead times of 30‑45 days after sample approval. Shipping is usually arranged in 20‑foot or 40‑foot containers, with pallets treated according to ISPM 15 and sealed with moisture‑resistant stretch film.
