Classification of men's synthetic knit overalls under HS 6103.43
Men's synthetic knit overalls are classified under HS code 610343. This classification follows the General Interpretative Rules (GIR) of the Harmonized System, specifically focusing on the garment's construction and fiber content. Chapter 61 is dedicated to articles of apparel and clothing accessories that are knitted or crocheted. This is a fundamental distinction in the textile industry, as knitted fabrics are formed by interlocking loops of yarn, providing inherent stretch and flexibility. Heading 6103 is the primary category for men's or boys' suits, ensembles, jackets, blazers, trousers, bib and brace overalls, breeches, and shorts. Within this heading, the system further differentiates products based on their constituent materials. Subheading 610343 is explicitly reserved for garments made of synthetic fibers. Synthetic fibers, as defined in the Section XI notes, include organic polymers such as polyamides (nylon), polyesters, and polyurethanes. To qualify for this code, the synthetic fiber must be the predominant textile material by weight. If a garment is a blend of 60% polyester and 40% cotton, it remains under this code. The 'bib and brace' designation refers to the specific silhouette of overalls that include a front chest panel and shoulder straps, distinguishing them from standard trousers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
