Hot-Dip Galvanized Corrugated Roofing Steel 0.6mm
Corrugated flat-rolled nonalloy steel sheet, hot-dip zinc coated, 0.6 mm thick and over 600 mm wide, designed for roofing applications. Falls under HTS 7210.49.00.91 as 'other' zinc-coated (non-electrolytic) products of thickness 0.4 mm or more; corrugation is considered a profile but base remains flat-rolled classification. Provides corrosion resistance for outdoor use.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If coated with zinc and further worked (corrugated > certain limits)
Chapter note defines 'further worked' including surface treatments; heavy profiling may qualify under 7210.41.
If painted or otherwise coated after zinc plating
Additional nonmetallic coatings (e.g., paint) over zinc classify under 7210.70 per chapter notes on further working.
If imported as finished roofing panels with accessories
Assembled or kit-form roofing shifts to fabricated metal structures in heading 7308.

Import Tips & Compliance
• Document zinc coating thickness and adhesion tests to confirm compliance with galvanizing standards
• Declare exact profile dimensions; excessive corrugation may trigger review for heading 7210.41 plated products
• Avoid common pitfall of undervaluing based on uncoated weight—use coated gross weight for valuation
