Last updated: August 2026 dataSilk and specialty natural fibers define the niche commercial segment covered by this residual heading, which captures knitted men's and boys' underpants and briefs not made of cotton or manmade fibers. Vietnam and China lead US imports, with Peru also a notable source — reflecting Peru's established fine-knit alpaca and pima cotton-adjacent textile sector, though alpaca (a fine animal hair) would fall here rather than under the cotton heading. The US schedule distinguishes briefs containing 70% or more silk (6107191000) from all other textile material briefs (6107199000), making silk content verification the primary classification step for luxury underwear in this heading.

Yes. Alpaca is a fine animal hair, not cotton or a manmade fiber, so knitted men's or boys' briefs made of alpaca would fall under heading 610719 as 'other textile materials.' They would be classified under 6107199000 unless the article also contains 70% or more silk by weight, which is commercially unlikely for alpaca-dominant goods.
Importers should obtain a fiber content analysis from an accredited textile testing laboratory confirming that the article contains 70% or more silk by weight. This lab report, along with the commercial invoice and product specification sheet, should be retained in the entry records. CBP may request this documentation during a CF-28 inquiry or audit.
