This heading captures all woven textile suits for men and boys whose chief-weight fiber is not wool or fine animal hair — including cotton, linen, polyester, rayon, and blended fabrics. Linen and cotton suits are fully within scope. The fiber content determines which specific HTS 10-digit line applies within the broader heading, so accurate fiber declaration remains essential regardless of fiber type.

Standard entry documentation includes a commercial invoice with fiber content breakdown, country of origin, and HTS classification. A textile visa or export license may be required depending on the country of origin and any applicable textile trade arrangements. Fiber content must also comply with FTC labeling requirements under the Textile Fiber Products Identification Act. For high-volume or high-value shipments, a pre-shipment inspection certificate or lab test report is advisable.
