Import Tips
• Obtain mill test certificates verifying chemical composition and mechanical properties for stainless steel grade compliance
• Ensure documentation specifies end-use in boilers or heat exchangers to avoid reclassification as general tubing
• Check for anti-dumping duties on certain stainless steel tubes from specific countries like China or India
