4203.29.30.10 - Not lined

This HTS category, 4203.29.30.10, specifically classifies men's gloves, mittens, and mitts that are not lined. The primary material of these items must be leather or composition leather, and they fall under the broader classification of men's apparel and clothing accessories. The "not lined" designation is a crucial differentiator, meaning these articles lack an inner textile or other material lining for added warmth, comfort, or structure.

This subcategory is distinguished from its sibling, 4203.29.30.20, by the explicit absence of lining. While both classify men's leather or composition leather gloves, mittens, and mitts, the presence or absence of an internal lining is the sole distinguishing feature at this level of detail. This distinction is vital for accurate tariff application and revenue collection.

As this is a leaf node in the HTS classification database, there are no further subcategories. Therefore, the classification concludes with the determination of whether the men's leather or composition leather gloves, mittens, or mitts are lined or unlined. Practical classification will focus on examining the physical construction of the article to confirm the absence of any internal lining material.
