Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designated for permanent mold vs sand casting
Foundry process specifics influence statistical reporting.
If alloyed and shaped into bars/profiles
Any forming beyond unwrought moves to Chapter 76 bars.
If containing significant slag/impurities
Slag and dross from aluminum use 2616, not pure ingots.

Import Tips & Compliance
• Require supplier declaration of conformance to Aluminum Association standards for alloy designation
• Document end-use as foundry melting stock to prevent misclassification as semi-fabricated
• Calculate duties based on gross weight; ingot strapping adds minimal but declarable weight
