6109.10.00.11 - Thermal undershirts (352) 🖩

This classification covers thermal undershirts knitted or crocheted, specifically those made of cotton and intended for men or boys. These garments are designed to provide insulation and warmth, serving as an inner layer of clothing. The designation "(352)" often refers to specific statistical suffixes or reporting requirements within customs systems, which may need further consultation for detailed compliance.

This specific category for thermal undershirts is distinguished from its siblings by its primary function as thermal wear. For instance, while sibling categories like "T-shirts, all white..." or "Singlets, all white..." focus on specific styles and colors of basic t-shirts and singlets, this category prioritizes the insulating properties and thermal function of the garment. It differentiates itself from "Other T-shirts" and "Tank tops and other singlets" by its specialized thermal purpose, even if it shares some basic construction similarities.

As this is a leaf node, there are no further subcategories. Classification decisions within this code will rely on determining if the garment is indeed a thermal undershirt, made of cotton, and for men's or boys' use. The key distinguishing factor from other t-shirt and singlet classifications at the same level is the garment's inherent thermal design and purpose.
