A ski suit presented as a matching set (jacket and trousers of the same fabric, designed and sold together for skiing) is classified as a ski suit under subheading 621120. If the jacket and trousers are sold separately or are of different fabrics, each piece is classified individually under its respective garment heading.

Woven athletic uniforms that do not fit the specific garment types enumerated in other headings (suits, trousers, shirts, etc.) are typically classified under the residual 'other garments' subheadings of 6211 (621132–621149), organized by gender and fiber content. The key is confirming woven construction and that the garment is not more specifically described elsewhere.
