Hastelloy C-276 Nickel Alloy Foil
Hastelloy C-276 nickel alloy foil, ultra-thin (under 0.15 mm), hot-rolled and not cold-formed, for chemical processing gaskets and linings. This nickel alloy foil does not meet the specific criteria of subheading 7506.20.10 (which requires less than 60% nickel for unworked foil), as Hastelloy C-276 has a higher nickel content. Therefore, it is classified under 7506.20.90 as 'other' nickel alloy foil.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the foil is unworked and contains less than 60% nickel by weight
Subheading 7506.20.10 specifically covers unworked nickel alloy foil with less than 60% nickel, which could apply if the alloy composition differs.
If the foil is cut to shape and becomes an article of another heading
If the foil is processed beyond the rolling mill state, it may be classified as an article rather than foil.

Import Tips & Compliance
• Measure the foil thickness precisely, as the 0.15 mm threshold is critical for classification
• Provide a certificate of analysis showing nickel content, as Hastelloy C-276 typically has over 50% nickel
• Ensure the foil is not 'worked' (e.g
• perforated or coated) to avoid reclassification
