Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing 3 or fewer parts per pitch
Simpler roller chains with ≤3 parts/pitch go to the parallel 'other' subheading 7315.11.0075.
If for bicycle-specific chain
Chains designed exclusively for bicycle use classify as bicycle parts under Chapter 87.
If as part of conveyor system
If imported as an integral conveyor part, it may fall under machinery parts in 8431.

Import Tips & Compliance
• Label with exact ANSI standard and pitch measurement; CBP may measure samples to enforce pitch limits
• Include material certificates confirming iron/steel composition to avoid misclassification to Chapter 73 non-chain items
• Watch for preferential tariff treatment under USMCA if from qualifying North American origins
