Galvanized Steel Roofing Flashing
Pre-cut galvanized steel strips used for weatherproofing roof joints, with zinc coating applied via hot-dip galvanizing process. Falls under HTS 7212.30.10.90 as flat-rolled nonalloy steel, width under 300 mm, thickness over 0.25 mm, and zinc-coated. The cladding provides corrosion resistance essential for outdoor roofing applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If width of 300mm or more but less than 600mm
Wider galvanized sheets fall under the 300-600mm subheading in heading 7210 for similar products.
If further fabricated into structural profiles or bars
Once bent or shaped beyond flat-rolled form, classified as structures in Chapter 73 rather than Chapter 72 semi-finished.
If coated with aluminum-zinc alloy instead of pure zinc
Aluzinc or Galvalume coatings use different metallizing process, moving to the 'other metal-coated' subheading.

Import Tips & Compliance
• Verify zinc coating thickness and method (hot-dip vs electro) meets ASTM A653 standards to avoid reclassification
• Provide mill test certificates confirming nonalloy steel composition and dimensions under 300mm width
• Watch for over 600mm widths which shift to 7210, causing higher duties; measure precisely before entry
