Import Tips
• 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
