Last updated: September 2026 dataDental floss — classified as yarn used to clean between the teeth — is a widely traded personal-care consumable that FDA regulates as a medical device under the Class II device framework, requiring 510(k) clearance or an applicable exemption before US market entry. All US imports fall under the single tariff line 3306200000. China is the dominant supplier, with Ireland and the Dominican Republic also notable sources; importers relying heavily on Chinese-origin floss should assess Section 301 tariff exposure as part of landed-cost modeling.

Yes. FDA classifies dental floss as a Class II medical device. Most conventional floss products are exempt from premarket notification (510(k)), but importers should verify that the specific product and any therapeutic claims (e.g., fluoride-coated floss) fall within the exemption. Establishment registration and device listing with FDA are generally required.
Regardless of whether the floss is made from nylon, PTFE (polytetrafluoroethylene), or natural silk, and whether it is waxed, flavored, or coated, the product classifies under 3306200000 as long as its intended use is interdental cleaning. A product marketed primarily as a textile yarn for other purposes would need to be evaluated under a different chapter.
