Last updated: July 2026 dataManmade fiber knit underpants and briefs — predominantly polyester, nylon, and microfiber constructions — are sourced primarily from Vietnam and China, with India, Sri Lanka, and Kenya also supplying the US market. The heading splits into men's (6107120010) and boys' (6107120020) lines under the general line (6107120000). Imports of Chinese-origin goods in this category are subject to Section 301 tariffs, making Vietnam and Sri Lanka attractive alternative sourcing destinations for buyers managing duty exposure on performance underwear and athletic brief styles.

Unlike some manmade fiber apparel headings (such as 610520 or 610620), heading 610712 does not subdivide by wool content in the US schedule. The lines here separate only by gender (men's vs. boys'). However, if a brief contains a very high proportion of wool, it could potentially be reclassified under heading 610719 (other textile materials), so fiber content documentation remains important.
Country of origin for knitted apparel is generally determined by where the fabric is knit to shape or where the cutting and sewing operations occur, following the 'substantial transformation' standard. For goods from countries with specific rules of origin under trade agreements or preference programs, the applicable rule may differ. Importers sourcing from multiple countries — including Vietnam, Sri Lanka, and Kenya — should maintain production records and certificates of origin to support CBP verification.
