Import Tips
• 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
