Import Tips
• Verify material composition via mill test certificates to confirm stainless steel grade and avoid misclassification as iron/steel articles
• Include detailed engineering drawings in documentation to prove it's a dedicated valve part, not a general machine component
• Watch for anti-dumping duties on certain stainless steel products from specific countries; check USTR notices
