6210.50.80.30 - Overalls and coveralls (759)

This classification pertains to women's or girls' overalls and coveralls that are constructed from specific non-woven or coated/impregnated fabrics listed in headings 5602, 5603, 5903, 5906, or 5907 of the Harmonized Tariff Schedule. The defining characteristic of goods within this subcategory is their fiber content, which must be 70 percent or more by weight of silk or silk waste. This includes garments designed as one-piece suits intended for work or as protective clothing, specifically for the female gender and youthful demographic.

In contrast to its sibling category, 6210.50.80.20, which covers women's or girls' trousers, breeches, and shorts made from similar materials, this classification is for more encompassing garment types like overalls or coveralls. It is also distinct from the sibling category 6210.50.80.40, which is a residual "Other" category for garments not otherwise specified at this level. The specific requirement of a silk content of 70 percent or more by weight is a crucial differentiator for these particular garments.

As a leaf node, this classification does not have further subdivisions. Therefore, the focus for classification within this code rests on ensuring the garment meets the definition of an overall or coverall, is intended for women or girls, is made from the specified fabric types, and crucially, contains at least 70 percent silk or silk waste by weight.
