Import Tips

Provide chemical analysis certificate proving alloy content (e.g

Cr, Mo) without exceeding tool steel thresholds from Chapter 72 note (e)

Declare exact dimensions; products over 600 mm width shift to different subheadings

Avoid common pitfall of assuming pickled surfaces are 'not further worked'—pickling is chemical treatment per notes
