Last updated: August 2026 dataPlastic closures — spanning injection-molded bottle caps, press-fit lids, child-resistant closures, and tamper-evident seals — are a high-volume packaging component serving food and beverage, pharmaceutical, personal care, and industrial chemical sectors. Classified under a single US 10-digit line (3923500000), the heading covers a wide range of resin types and closure designs, making product-specific documentation important for buyers managing material compliance (e.g., food-contact regulations). Mexico, China, and Canada are the leading import sources, with Mexico and Canada benefiting from integrated North American packaging supply chains under USMCA. Chinese-origin plastic closures have been subject to Section 301 tariffs, a factor that has driven sourcing diversification toward Mexico and other suppliers.

Chinese-origin plastic closures classified under 3923500000 have been subject to Section 301 tariffs, increasing landed costs and prompting many US importers to shift sourcing toward Mexico and Canada — where USMCA preferential treatment applies — as well as other Asian suppliers. Importers should verify current Section 301 list status and any applicable exclusions with a licensed customs broker, as the landscape has evolved through multiple rounds of review.
Plastic closures intended for direct food contact must comply with FDA regulations governing food-contact materials, including applicable food additive regulations for the resin type used. Importers typically require a food-contact compliance letter or statement from the manufacturer confirming that the closure meets FDA requirements for the intended use conditions (e.g., temperature, food type). Some buyers also require compliance with EU food-contact regulations if the product is dual-marketed.
