6211.49.03.10 - Coveralls, jumpsuits and similar apparel:

This HTS classification, 6211.49.03.10, specifically designates coveralls, jumpsuits, and similar apparel designed for women or girls, when such garments are composed of 70 percent or more by weight of silk or silk waste. These items fall under the broader category of "other garments" within women's and girls' apparel not knitted or crocheted, and are distinguished by their material composition. The focus here is on garments that are typically worn as a single piece for recreational or performance purposes, reflecting the "recreational performance outerwear" context.

Within the sibling categories at this level, 6211.49.03.10 is distinct from items like washsuits, sunsuits, and playsuits (6211.49.03.20), which are generally designed for younger children or less performance-oriented activities. It also differs from track suits, which are typically sold as a set, and from blouses, shirts, and shirt-blouses (6211.49.03.50), which are upper body garments only. Similarly, jumpers and vests, classified under 6211.49.03.60 and 6211.49.03.70 respectively, are separate garment types. The defining characteristic for 6211.49.03.10 is the one-piece construction of coveralls or jumpsuits, combined with the specified silk content.

As this is a leaf node, there are no further subcategories. The classification is therefore definitive for garments meeting all the preceding criteria: being women's or girls' apparel, not knitted or crocheted, classified as "other garments," falling under recreational performance outerwear, and critically, being made of 70 percent or more silk or silk waste, in the form of coveralls or jumpsuits. Practical classification will rely on verifying the material composition and the garment's style and intended use.
