Import Tips

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
