Last updated: July 2026 dataRoller chain — the precision-linked drive chain used in bicycles, motorcycles, conveyors, agricultural machinery, and industrial power-transmission systems — is classified under SITC 74831 and is one of the more trade-remedy-sensitive mechanical components in the category. Antidumping duty orders have covered roller chain from certain origins for decades, making origin verification and scope analysis a standard step in procurement. Pitch size (measured in inches or millimeters), strand count, and tensile strength are the primary specification variables that differentiate standard, heavy-duty, and corrosion-resistant grades.

Antidumping orders on roller chain have historically defined scope by pitch range (e.g., chains with pitches from a specified minimum to maximum). Chains outside the covered pitch range may fall outside the order's scope entirely. Importers should compare their product's pitch specification against the exact scope language of any active order and consider a scope ruling if the pitch is near a boundary.
Roller chain is characterized by its cylindrical rollers that rotate on bushings between inner link plates, reducing friction with the sprocket teeth. It is distinguished from silent chain (inverted-tooth chain), leaf chain, and engineering-class conveyor chain, which occupy different tariff subheadings. The manufacturer's product designation and technical drawing are the most reliable classification evidence.
