U.S. imports of knit t-shirts, singlets & tank tops of other textile materials (HS 610990) totaled $134.5M in April 2026, traded with 106 countries.
Importers of Knit T-Shirts, Singlets & Tank Tops of Other Textile Materials paid $24.7M in duties in April 2026 — an effective duty rate of 30% on $83.5M in dutiable value, based on actual customs collections rather than the published tariff schedule. Knit T-Shirts, Singlets & Tank Tops of Other Textile Materials imports of $134.5M in April 2026 ran 10% below the year-to-date monthly average of $149.7M.
Last updated: April 2026 dataManmade fiber, wool, silk, and other non-cotton knit T-shirts and tank tops fall under this residual heading, which carries the most complex 10-digit structure in the chapter — 27 active lines covering manmade fiber garments by gender and garment type, wool garments with long sleeves, silk-content articles at 70% or more, and all remaining textile materials. Manmade fiber T-shirts, particularly polyester performance and athleisure styles, dominate commercial volume. Vietnam leads US supply, with Honduras and Nicaragua — CAFTA-DR partners — ranking second and third, reflecting significant regional production of synthetic-blend activewear.

When manmade fibers (such as polyester) predominate by weight, the garment is classified under heading 610990 rather than 610910 (cotton). The applicable 10-digit line within 610990 then depends on gender and garment type — for example, 6109901007 for men's T-shirts of manmade fibers. Fiber content certification from the mill is the standard supporting document.
The US schedule includes specific lines (e.g., 6109901510 through 6109901550) for wool garments with long sleeves, reflecting a construction distinction from short-sleeve T-shirt styles. A long-sleeve wool undershirt or thermal top falls under these lines, while a short-sleeve wool T-shirt would fall under the general 'other textile materials' lines. Sleeve length and garment construction details on the commercial invoice are therefore classification-relevant.
