Import Tips & Compliance
• Require chemical analysis reports confirming high-nickel (e.g
• Ni 50-60%) to differentiate from standard stainless
• Ensure welding method documentation (e.g
• TIG welded) and inspect for circular profile to prevent misclassification
• Avoid pitfalls by labeling as 'other tubes/pipes' not fittings; check for anti-dumping duties on certain alloys
