AISI 4340 Hot-Rolled Nickel-Chromium-Moly Steel Coil
Hot-rolled coil of AISI 4340 alloy steel (Ni-Cr-Mo) with 2.5 mm thickness and 1500 mm width, used for structural components. Falls under HTS 7225.30.70.00 as other hot-rolled alloy steel coils, width ≥600 mm, thickness <4.75 mm, excluding high-strength specs.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If meets high-strength steel definition
Minimum yield strength exceeds thresholds in US Note 72(a) for structural-grade high-strength applications.
If surface-treated (e.g., oiled or phosphatized)
Chemical surface treatments qualify as 'further worked' per US Chapter Note, shifting from hot-rolled category.
If insufficient alloy elements
If total alloying < required minimums, reclassifies as carbon steel under heading 7208.

Import Tips & Compliance
• 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
