EC Grade Aluminum Alloy Grain Refiner
EC grade aluminum alloy grain refiner, a master alloy of aluminum with titanium and boron, in rod or pig form for producing electrical conductor wire. The aluminum content predominates, and the titanium/boron additions exceed the alloy limits, so it is an unwrought aluminum alloy.

Import Tips & Compliance
• Confirm the product is in unwrought form (pig or rod) and not further processed
• Provide a detailed composition breakdown to show it is an alloy, not a mixture
• Note that grain refiners may also be classified under heading 3815 if presented as chemical preparations
