Import Tips
• Include material grade certificates (e.g
• ASTM A790 for duplex) to substantiate stainless steel classification
• Avoid common pitfall of declaring as 'tubing' instead of 'casing' which could lead to 7306 headings
• For sets with couplings, declare as individual lengths unless permanently assembled per GRI 2(a)
