This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If refined copper predominates with tin as minor addition
Copper-tin alloys like phosphor bronze are classified under copper refined metals when copper is primary.
If for high-purity tin bars used in alloy production
Non-alloyed tin (99%+ purity) is under 8001.10, not alloys.
If chemically defined as a prepared additive mixture
Certain master alloys may be seen as chemical preparations rather than base metals.

Import Tips & Compliance
• Provide detailed chemical analysis proving tin >50% by weight and alloy status
• Label shipments clearly as 'unwrought alloys' to prevent confusion with wrought forms in Chapter 81
• Check for anti-dumping duties on specific tin alloy compositions from certain origins
