Last updated: April 2026 dataChina is the dominant supplier of children's modeling pastes entering the US, while Germany and Japan lead in the more technically demanding dental impression compounds and plaster-based dental preparations segment. The US schedule divides this heading into modeling pastes put up for children's amusement (3407002000) and dental impression compounds or waxes for retail sale (3407004000), a split that carries very different regulatory implications. Dental impression compounds and plaster-based preparations intended for clinical use are subject to FDA oversight as medical devices, requiring importers to confirm device registration and 510(k) clearance status before entry. Children's modeling pastes face CPSC safety and labeling requirements, including restrictions on certain colorants and preservatives.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Dental impression compounds and plaster-based preparations intended for professional or clinical dental use are regulated by FDA as medical devices. Importers must ensure the foreign manufacturer is registered with FDA and that the product has appropriate 510(k) clearance or is otherwise exempt. Admissibility is complex; consult a licensed customs broker or regulatory counsel familiar with FDA device requirements.
Line 3407002000 covers modeling pastes put up specifically for children's amusement (e.g., play dough), while 3407004000 covers dental impression compounds and waxes sold at retail. The distinction matters because the two lines may carry different duty rates and trigger entirely different regulatory review pathways — CPSC for children's products versus FDA for dental materials.
