Heading 6110 covers pullovers, sweatshirts, waistcoats, and similar articles typically pulled on over the head or with a partial front opening. A knit article with a full-length front opening and the character of a jacket or blazer is more likely to classify under the heading for men's or women's suits and jackets. The key test is whether the article's construction and design align with the sweater/pullover family or with outerwear jackets.

US Customs and Border Protection may require laboratory fiber analysis to confirm cashmere content. The Wool Products Labeling Act also mandates accurate fiber disclosure on labels. Importers should obtain mill certificates or fiber-content test reports from suppliers to support classification and labeling compliance.
