Grade 50W Weathering Steel Plate

Hot-rolled Grade 50W high-strength low-alloy weathering steel plate, 18 mm thick, 1800 mm width, not further worked. Yield strength 50 ksi (345 MPa) qualifies as high-strength steel; atmospheric corrosion resistance from copper addition but remains nonalloy steel.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

7210.41.00.00Same rate: 35%

If identifiable as alloy steel (total alloys ≥2%)

Weathering steels with higher alloy content for corrosion resistance classify as alloy under 7210

7208.51.00Same rate: 35%

If thickness 10 mm or less but >4 mm

Thinner high-strength plates use sequential statistical suffixes within 7208.51

7308.90.95Same rate: 35%

If fabricated into structural shapes rather than flat plate

Fabricated steel structures/assemblies move to Chapter 73 heading 7308

Our AI classifier can analyze your specific product and recommend the correct HTS code with confidence.

Import Tips & Compliance

Verify total alloy content <2% to remain nonalloy steel; weathering elements like Cu/P don't change classification

Document hot-rolling process and absence of post-rolling treatments to prevent 7211 reclassification
