Import Tips
• Provide evidence of intended use for infrastructure; however, classification remains based on objective characteristics like welding and galvanization
• Test for zinc coating thickness (typically 50-100 g/m²) to confirm 'galvanized' status per HTS note
• Bundle documentation including chemical analysis confirming nonalloy steel (carbon ≤0.25%, no significant alloying elements)
