Last updated: August 2026 dataCotton knit T-shirts, singlets, and tank tops form one of the highest-volume apparel categories in US import trade, with the tariff schedule subdivided across 18 active 10-digit lines separating gender, age group, underwear versus outerwear function, and color (all-white versus other). Bangladesh leads US supply by a wide margin, reflecting its dominant position in basic cotton knit apparel, with Honduras and Nicaragua — both CAFTA-DR partners — also major sources. The underwear/outerwear distinction is a persistent classification issue: all-white singlets (6109100007) are treated as underwear, while colored or printed versions typically fall under the outerwear T-shirt lines.

CBP applies a totality-of-circumstances test considering color (all-white is a strong indicator of underwear), fabric weight, construction, and marketing. All-white singlets sold in multi-packs as underwear typically fall under 6109100007, while white T-shirts marketed as outerwear or bearing graphics may be classified under the outerwear lines. Packaging, labeling, and commercial invoices describing end use are key supporting documents.
Honduras and Nicaragua are CAFTA-DR partners, and qualifying cotton T-shirts that meet the agreement's yarn-forward rule of origin may enter duty-free. To claim CAFTA-DR preference, the importer must have a valid certification of origin and the goods must satisfy the applicable textile rule — generally requiring that the yarn, fabric, and cutting/sewing all occur within CAFTA-DR territory. Importers should confirm rule-of-origin compliance with their customs broker before claiming the preference.
