6110.20.10.22 - Men's or boys' (359)

This HTS classification covers men's or boys' vests that are knitted or crocheted, specifically those containing 36 percent or more by weight of flax fibers, and are not sweater vests. These items are designed to be worn as an outer layer or undergarment, providing warmth or as a fashion item. The key defining characteristics for this category are the gender of the wearer (men's or boys'), the construction method (knitted or crocheted), the presence of a significant flax fiber content, and the absence of sweater vest styling.

Distinguishing this category from its sibling, 6110.20.10.24, lies solely in the intended gender of the wearer. While both classifications pertain to knitted or crocheted vests with a high flax fiber content, this specific code is exclusively for items designed for males, whereas the sibling code is for females. This gender-based distinction is a crucial factor in accurate tariff classification.

As this node is a leaf node in the HTS structure, there are no further subcategories. Classification ends here, meaning that once an article meets all the criteria for this specific code – being a men's or boys' knitted or crocheted vest with at least 36% flax fiber content and not being a sweater vest – it is definitively classified under 6110.20.10.22. Importers and customs officials should ensure all these attributes are met for correct duty assessment and trade compliance.
