Import Tips

Submit chemical analysis certificate proving alloy status (Ni 1.65-2%, Cr 0.4-0.8%) and non-stainless (<10.5% Cr)

Verify coil form and no further working (e.g

no pickling beyond hot-rolling scale); document hot-rolling process

Avoid common pitfall of thickness mismeasurement leading to duty reassessment under 7225.30.80 for thicker products
