Buy & Import Chains from Jingjiang Dastong International Co., Ltd. - Wholesale Supply

Jingjiang Dastong International Co., Ltd. supplies industrial and motorcycle chains in standard sizes including 25H(04CH), 415, 415H, 420, 420H, 428, 428H, 520, 520H, 525, 525H, 530, and 530H. These chains are manufactured with carbon steel bodies and hardened pins, offering tensile strength suitable for medium to heavy-duty applications. The pitch and roller diameter conform to ANSI B29.1 standards for interoperability with common sprockets.

The chains are built for use in agricultural machinery, conveyor systems, and motorcycle drivetrains. Material composition is typically medium-carbon steel with surface treatment to resist corrosion and wear. While the listing claims ISO certification, no certificate number or scope is provided. Industry-standard endurance testing follows ASTM A29 for mechanical properties, but the supplier does not publish test reports.

Buyers commonly source these chains for replacement in farm equipment and small industrial conveyors. Packaging is in polyethylene-lined cartons, with bulk quantities shipped in wooden crates. Trade terms include FOB Shanghai and CIF ports in Southeast Asia and the Middle East. Minimum order quantities are flexible but typically start at 500 meters per size. Lead time is 30 to 45 days after deposit confirmation.

Frequently Asked Questions About Chains from Jingjiang Dastong International Co., Ltd.

Sourcing Chains from Jingjiang Dastong International Co., Ltd. - China Import Guide

Before ordering, verify the exact chain size and pitch against your sprocket specifications. Request a sample to confirm roller diameter, plate thickness, and pin alignment. Do not rely on nominal size labels alone. Ask for dimensional drawings or a sample inspection report. Confirm whether the chain is designed for agricultural, motorcycle, or industrial use, as load profiles vary significantly.

Lead time is typically 30 to 45 days after deposit. Confirm Incoterms - FOB Shanghai is listed, but clarify who pays for port charges, insurance, and customs clearance. Payment terms are not stated; request a proforma invoice with payment schedule. Ensure packaging is labeled with size, quantity, and batch number. Avoid payment in full before shipment without inspection rights.

Conduct a pre-shipment inspection for chain straightness, pin rotation, and surface finish. Use a chain wear gauge to measure elongation on a sample. Check for cracks in side plates and consistent hardness across links. Request a Certificate of Conformity and material test report. Retain a sample for future comparison. Document all findings in writing before accepting delivery.
