6109.90.80.10 - Men's or boys' (838)

This HTS code, 6109.90.80.10, specifically classifies men's or boys' knitted or crocheted singlets, tank tops, and similar garments. These are typically sleeveless or have very minimal shoulder straps, designed for casual wear or as undergarments. The key defining characteristics are the knitted or crocheted construction and their classification as singlets, tank tops, or garments of a similar basic construction.

This category is distinguished from its sibling, "Women's or girls':", by the gender and age designation of the wearer. While the garment type may be similar, the specific sizing, cut, and intended use for men or boys is the determining factor for classification under this code. Both categories fall under the broader umbrella of "T-shirts, singlets, tank tops and similar garments, knitted or crocheted: Of other textile materials: Other," indicating they are not made of cotton, synthetic, or artificial fibers, but rather from other textile materials.

As this represents a leaf node in the HTS classification, there are no further subcategories for this specific code. Therefore, the classification hinges entirely on the garment's construction (knitted or crocheted), its type (singlet, tank top, or similar), its intended wearer (men or boys), and its material composition (other textile materials). When classifying, customs officials will look for these specific attributes to ensure accurate duty assessment and trade compliance.
