Last updated: July 2026 dataCotton and man-made fiber T-shirts, singlets, and tank tops knitted or crocheted are among the highest-volume apparel imports entering the United States, serving everything from basic underwear to branded fashion and athletic wear. Fiber content — particularly the cotton-versus-man-made-fiber split — determines the applicable HTS subheading and duty rate, while the garment's intended use (underwear versus outerwear) can also influence classification at more granular levels. Importers should be aware that this category has historically attracted CBP scrutiny for undervaluation and fiber-content misrepresentation, given its commodity-like pricing and high import volumes.

At the SITC heading level, T-shirts and singlets are grouped together regardless of underwear or outerwear designation. At the HTS 10-digit level, however, some subheadings distinguish between underwear and other T-shirts, which can affect the applicable duty rate. The garment's construction, labeling, and marketing context are all factors CBP may consider when making this determination.
CBP frequently flags T-shirt shipments for fiber-content discrepancies (e.g., a garment declared as 100% cotton that tests as a cotton-polyester blend), undervaluation relative to market benchmarks, and country-of-origin issues where substantial transformation is claimed in a third country. Maintaining mill certifications, accurate cost documentation, and clear production records helps importers defend against these challenges.
