US tariff practice generally treats 'babies'' garments as those sized for children up to approximately 24 months or body size 2T. Articles sized above that threshold are typically classified under the relevant children's or boys'/girls' garment headings. When a size range straddles the boundary, the importer should document the sizing standard used and consult a customs broker.

Clothing accessories for babies — including bibs, booties without applied soles, and similar items — are intended to be captured within 6111 alongside garments. However, booties with applied soles may be redirected to the footwear chapters. Classification of borderline accessories should be confirmed against the heading text and relevant chapter notes.
