Last updated: August 2026 dataKnitted and crocheted underpants and briefs for men and boys represent a high-volume, price-sensitive segment of the US apparel import market, where cost competitiveness is closely tied to origin and fiber mix. Section 301 tariffs have affected sourcing economics for shipments from certain origins, prompting supply-chain shifts toward alternative manufacturing countries. Correct classification requires distinguishing these articles from swimwear or athletic shorts, which are governed by separate headings based on intended use and construction.

CBP guidance focuses on the article's primary design and intended use: briefs and underpants are designed as undergarments, while swimwear is constructed with features like a lining, drawstring, or water-resistant fabric suited for aquatic use. Athletic shorts worn as outerwear are similarly classified separately. Misclassification between these categories is a common audit finding.
The US eliminated most textile and apparel quotas for WTO members after 2005, but certain bilateral agreements and safeguard mechanisms may still apply depending on origin. Importers should verify current CBP and OTEXA guidance for the specific country of manufacture, as requirements can change with trade policy developments.
