Quick Answer: Dental floss, classified under HS code 330620, enters the UK at 4.00%, the EU at 4.00%, and the US at a rate of 88¢/kg + 75% ad valorem, with a free rate also available under certain conditions. This specific HS code covers yarn, typically made of nylon or PTFE, designed for cleaning between teeth. Importers should be aware of the significant ad valorem component in the US duty, which can substantially increase the landed cost for higher-value floss.

How to Classify This HS Code?
What products does HS 330620 cover?
This subheading covers "Yarn used to clean between the teeth (dental floss)" as per the World Customs Organization's Harmonized System Nomenclature. Official definitions, such as those found in the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, confirm that this classification applies to filamentary materials, typically made of nylon, polyester, or PTFE, specifically designed and marketed for interdental cleaning. These products are intended for personal oral hygiene and are distinct from general-purpose threads or yarns.
What falls outside HS 330620?
The following products are excluded from HS 330620: general-purpose sewing threads, which are classified under Chapter 50-62 depending on the material; dental picks or sticks made of wood or plastic, which would fall under Chapter 44 or 39 respectively; and mouthwash or other oral hygiene preparations, which are classified under HS 330690. The key differentiator is the form and intended use; only filamentary yarn specifically for interdental cleaning falls within this subheading.
What are common classification mistakes for HS 330620?
A common error is classifying dental floss that has been impregnated with therapeutic agents, such as fluoride or antimicrobial substances, under this subheading. While the base material is yarn, the addition of active pharmaceutical ingredients may necessitate classification under Chapter 30 (Pharmaceutical products) or a more specific subheading within Chapter 33 if the primary function is therapeutic, following General Rule of Interpretation (GRI) 3(b) where mixtures are classified by their essential character.
How should importers classify products under HS 330620?
The correct procedure for classifying products under HS 330620 involves verifying that the product is indeed a yarn specifically designed for cleaning between teeth. Importers and customs brokers must examine product descriptions, marketing materials, and the physical characteristics of the item. Consulting the relevant national tariff schedule, such as the USITC HTS or the UK Trade Tariff, for specific explanatory notes and rulings is crucial to ensure accurate classification and avoid potential delays or penalties.
How is the duty calculated for products under HS 330620?
A pack of 10 spools of mint-flavored dental floss weighing a total of 100 grams and declared at a customs value of $25.00 USD would attract a US duty of $0.00. This is because the Most Favored Nation (MFN) duty rate for HS 330620 in the USITC Harmonized Tariff Schedule is 0% ad valorem. Therefore, the calculation is 0% × $25.00 = $0.00.
Which trade agreements reduce duties for HS 330620?
Several free trade agreements may reduce the applicable duty rate for HS 330620, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer preferential rates for goods from certain developing countries, potentially leading to a Free duty rate. To claim these preferences, a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries is typically required, depending on the specific jurisdiction and agreement.

FAQ
What are the typical import duty rates for dental floss (HS 330620) into the United States?
Under the Harmonized Tariff Schedule of the United States (USHTS), dental floss (HS 330620) is generally subject to a Most Favored Nation (MFN) duty rate of 4.00% ad valorem. It is crucial for importers and customs brokers to consult the latest USHTS, accessible via the U.S. International Trade Commission (USITC) website, as duty rates can change. Additionally, importers should verify if any preferential rates under Free Trade Agreements (FTAs) apply to their specific country of origin, which could result in a lower or free duty rate.
How is the duty for dental floss calculated if it has a specific weight-based component in addition to an ad valorem rate?
While the U.S. MFN rate for dental floss is typically ad valorem (based on value), some countries may apply a compound duty structure (ad valorem plus a specific rate per unit of quantity). For example, if a country's tariff listed a duty of 88¢/kg + 75% ad valorem for HS 330620, and you imported 10 kg of dental floss valued at $100 USD (assuming an exchange rate where $1 USD = 100¢), the calculation would be: (0.88 USD/kg * 10 kg) + (0.75 * $100 USD) = $8.80 USD + $75.00 USD = $83.80 USD. Importers and brokers must carefully review the specific tariff schedule of the importing country for the exact duty calculation method.
What are the key classification criteria for dental floss under HS code 330620?
HS code 330620 specifically covers 'Yarn used to clean between the teeth (dental floss)'. The primary classification criterion is the intended use: the product must be designed and marketed for interdental cleaning. This typically includes floss made of synthetic or natural fibers, often coated with wax or fluoride, and usually presented in spools or dispensers. Products that are not specifically for interdental cleaning, such as general-purpose sewing thread or cleaning rags, would not fall under this heading. Verification of product labeling and marketing materials is essential for correct classification.
What documentation is typically required for importing dental floss (HS 330620) into the EU?
When importing dental floss (HS 330620) into the European Union, importers and customs brokers must ensure they have a complete set of import documents. This typically includes a commercial invoice, a packing list, a bill of lading or air waybill, and an import declaration. Depending on the origin of the goods, a certificate of origin may be required to claim preferential duty rates under various EU trade agreements. It is also advisable to check the EU's TARIC database for any specific import licensing, sanitary, or phytosanitary requirements, although these are less common for dental floss compared to food or pharmaceutical products. Compliance with REACH regulations regarding chemical substances may also be relevant.
Are there common trade agreements that offer preferential duty rates for dental floss imported into the UK?
Yes, the United Kingdom has various trade agreements that can offer preferential duty rates for goods, including dental floss (HS 330620), depending on their country of origin. For instance, goods originating from countries with a Free Trade Agreement (FTA) with the UK may qualify for reduced or zero duty rates. Importers and customs brokers should consult the UK Trade Tariff, available on the GOV.UK website, to identify applicable FTAs and the specific rules of origin required to claim preferential treatment. Proof of origin, such as a EUR.1 movement certificate or an origin declaration on the invoice, is typically necessary.
