Product classification
HS code for Dental floss: 3306.20
Oral or dental hygiene preparations, yarn used to clean between the teeth (dental floss).
Classification of dental floss under HS 3306.20
Dental floss is classified under HS code 3306.20. This code is part of Chapter 33, which covers essential oils and resinoids, perfumery, cosmetic, or toilet preparations. Specifically, heading 3306 is dedicated to preparations for oral or dental hygiene. While one might assume dental floss belongs in a textile category due to its yarn-like structure, the Harmonized System explicitly places \"yarn used to clean between the teeth (dental floss)\" within the oral hygiene preparations heading. This classification applies regardless of whether the floss is flavored, waxed, or packaged for retail sale. The logic behind this placement is that the primary use of the product is for the maintenance of dental health and hygiene rather than for general textile applications. The Explanatory Notes to the Harmonized System (ENHS) for heading 3306 clarify that this subheading includes yarn used to clean between the teeth, provided it is in packages of a kind sold by retail for such use. If the yarn is not prepared for retail sale as dental floss, it might be classified elsewhere, but for the vast majority of commercial dental floss products, 3306.20 is the mandatory code. This classification reflects the transition of a raw material (yarn) into a specialized health product through specific processing and packaging. The inclusion of dental floss in this chapter highlights the importance of oral care products within the global cosmetic and toilet preparation market.

Codes often confused with 3306.20
Common mistake. Dental floss is often misclassified under Chapter 54 (Man-made filaments) or Chapter 55 (Man-made staple fibers), specifically codes like 5402.11, because it is essentially a high-tenacity yarn. However, Note 4 to Chapter 33 and the specific wording of 3306.20 clarify that dental floss is excluded from textile chapters and must be classified here. Another confusion arises with 3306.10, which is for dentifrices (toothpaste); while both are oral hygiene products, floss has its own dedicated subheading that must be used to ensure accurate customs declarations.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
