Last updated: August 2026 dataDental cements, composite resins, glass ionomers, and bone-reconstruction preparations used in restorative and surgical dentistry are classified here, with Germany and France among the leading suppliers to the US market. FDA regulates these products as Class II or Class III medical devices, meaning 510(k) clearance or premarket approval is typically required before importation. The single 10-digit line (3006400000) covers the full range of dental filling and cementing materials, so product-specific device classification determines the applicable FDA regulatory pathway rather than tariff subheading. Importers should confirm that the foreign manufacturer holds a valid FDA device registration and that each product has the appropriate marketing authorization on file.

Yes. Dental cements and filling materials are regulated as medical devices by FDA. Foreign manufacturers must be registered with FDA, and each product must have a valid 510(k) clearance or premarket approval before it can be legally marketed or imported into the United States. Consult a licensed customs broker or regulatory counsel to confirm the specific device class and clearance status.
Dental cements and fillings are specifically enumerated in heading 3006.40 and are classified there regardless of their chemical composition (e.g., zinc oxide-eugenol, glass ionomer, resin composite). Products that are purely pharmaceutical in nature without a dental-filling or cementing function would fall under other headings in Chapter 30. The intended clinical use — restoring or cementing tooth structure — is the primary classification criterion.
