Last updated: April 2026 dataKnit construction — typically elastane-blended fabrics such as nylon/spandex — defines this category and distinguishes it from woven swimwear for classification purposes. Buyers should note that fiber content, fabric weight, and the presence of built-in bra cups or padding can shift classification between swimwear and other knitted garments. Quota history and textile visa requirements under bilateral agreements have historically affected sourcing decisions for this performance-oriented category.

Fiber composition matters because swimwear with a high elastomeric content (e.g., spandex/Lycra blends) must still meet the principal-fiber rule for textile classification. If the garment's chief weight is nylon, it classifies under nylon provisions; if polyester predominates, it falls under polyester provisions. Misidentifying fiber content is a common audit trigger — lab testing at entry is advisable for mixed-fiber styles.
Generally, minor functional features like removable padding or shelf bras do not move a garment out of the swimwear heading, provided the article is still commercially recognizable as swimwear. However, structured underwire bras sewn into a two-piece top can invite scrutiny; CBP has ruled on similar garments case by case, so a binding ruling request is advisable for novel designs.
