Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If thickness exceeding 0.25 mm but ≤0.5 mm
Thickness threshold separates thin foil from thicker strip within same cold-rolled alloy category.
If made into welded wire mesh
Fabricated articles change classification from flat-rolled to other steel articles.
If End-use parts of electrical machinery may take 85xx classification over base material.

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.
Import Tips & Compliance
• Critical thermal expansion specs must match invoice; mismatch leads to reclassification disputes
• Foil must arrive in protective packaging; rust/discoloration gets no duty allowance per Chapter 72 note
• Verify no heat treatment post-rolling; annealing would constitute further working
