An inflatable article is one designed to be filled with air or gas under pressure to achieve its functional form — such as a pneumatic seal that expands when pressurized to close a gap. A hollow rubber article that is not intended to be inflated (e.g., a rubber ball with a fixed air pocket) may instead classify under 401699 or another specific heading. The article's design intent and whether it has a valve or inflation port are key indicators.

Imports from Mexico may qualify for USMCA preferential tariff treatment if the goods satisfy the applicable rules of origin, including tariff-shift and regional value content requirements. Importers must obtain a valid USMCA certification of origin and retain it for five years per CBP requirements. Given Mexico's position as the leading supplier under this heading, verifying origin compliance is a routine step for cost management.
