Woven boxer shorts worn as underwear are classified under 6207 (underpants and briefs, subheadings 620711 or 620719 by fiber). Shorts intended as outerwear — even if similar in cut — are classified under 6203. The intended use and retail presentation (underwear packaging vs. outerwear) are the primary indicators.

Classification depends on the outer fabric construction. If the outer shell is woven (not knitted), the garment falls under 6207 (subheadings 620791 or 620799). If the entire garment is terry-cloth knit, it would fall under the knitted garments chapter. The chief fabric by surface area and construction method govern.
