Import Tips

Verify fiber content exceeds 50% cotton via lab tests to confirm Chapter 61 classification and avoid reclassification to synthetic headings

Ensure no drawstring, ribbed waistband, or bottom tightening features, as per heading 6109 notes, to prevent shift to other T-shirt subheadings

Label garments clearly as 'men's' based on left-over-right front closure or cut, per chapter notes, for proper statistical suffix (352)
