Import Tips & Compliance
• Ensure the foil is 'worked' (e.g
• cut to shape, perforated, or coated) to qualify for 7506.20.90, as unworked foil under 0.15mm falls under 7506.20.10
• Provide a mill test certificate confirming the alloy composition (e.g
• UNS N06022) to support the nickel alloy classification
• Verify if the product qualifies for preferential tariff treatment under a free trade agreement by declaring the origin in the commercial invoice
