Import Tips
• Include precipitation hardening alloy certification with Cu/Nb content for proper stainless identification
• Avoid bulk packaging that distorts dimensions; measure in entry condition per HTS requirements
• Differentiate from tool steels (U.S
• Note e) by confirming not meeting specific high-carbon/high-Cr criteria
