Import Tips

Submit chemical analysis reports from accredited labs to prove compliance with low carbon and high Mn/Si thresholds

Label spools clearly with HTS code, alloy specs, and 'for welding use only' to aid customs inspection

Beware of rust/discoloration claims; Chapter 72 notes deny duty reductions for pre-entry corrosion on steel wire
