Import Tips & Compliance

Submit detailed chemical composition reports proving alloy status (Ni, Cr, Mo content) per Chapter 72 notes

Measure width and thickness precisely; products ≥4.75mm shift to different statistical suffixes

Avoid reclassification pitfalls by ensuring no phosphatizing or other chemical treatments occurred post-rolling
