Beach cover-ups and sarongs are generally not classified as swimwear under this heading unless they are specifically designed and marketed as swimwear components. Most cover-ups are classified as dresses, skirts, or other garments depending on their construction and design. Only articles that function as swimwear — designed to be worn in or immediately around water — qualify for the swimwear heading. Importers should ensure product descriptions and labels accurately reflect the garment's intended use.

Structural elements such as underwire or boning do not typically redirect a woven one-piece swimsuit out of the swimwear heading, provided the garment's overall character remains that of swimwear. The swimwear heading is broad enough to accommodate structured designs. However, if the article more closely resembles a bodysuit or foundation garment with only incidental swimwear features, reclassification could be considered. Clear swimwear labeling and marketing documentation support the swimwear classification.
