CBP looks at design features, marketing, and intended use. Garments marketed and designed for sleeping — such as those with longer hemlines, lightweight fabric, and sleepwear-style packaging — are more likely to be accepted as sleepwear under 6207913010. Plain, shorter garments sold as undershirts classify under 6207913020. Importers should retain product catalogs, hang tags, and marketing materials to support the intended-use determination.

Yes. In addition to the Textile Fiber Products Identification Act labeling (fiber content, country of origin, manufacturer identity), bathrobes sold in the US retail market may be subject to flammability standards under CPSC regulations, particularly for children's sizes. Importers should confirm compliance with applicable CPSC flammability rules before the goods enter commerce.
