HS 382763 Other, not included in the subheadings above, containing 40 % or more by mass of pentafluoroethane (HFC-125)
Quick Answer: Mixtures containing 40% or more by mass of pentafluoroethane (HFC-125) imported under HS 382763 enter the UK at 6.00%, the EU at 6.50%, and the US at 3.7% (MFN). This classification covers various chemical mixtures not specified elsewhere, primarily refrigerants or blowing agents, where pentafluoroethane is a significant component. Importers should be aware of potential environmental regulations and quotas, particularly concerning hydrofluorocarbons (HFCs), which may apply in addition to customs duties.

How to Classify This HS Code?
What products does HS 382763 cover?
This subheading covers chemical mixtures and preparations, not elsewhere specified or included in Heading 3827, that contain 40% or more by mass of pentafluoroethane (HFC-125). According to the WCO Harmonized System Nomenclature and as reflected in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database, this category is specifically for refrigerants and blowing agents where HFC-125 is a significant component, excluding pure HFC-125 itself which may fall under other headings. The key criterion is the presence of pentafluoroethane at or above the 40% mass threshold.
What falls outside HS 382763?
The following products are excluded from HS 382763: pure pentafluoroethane (HFC-125), which is typically classified under HS 2903.49.0000 or similar headings depending on the specific tariff schedule and its purity. Mixtures containing less than 40% by mass of pentafluoroethane are also excluded, as are products that are specifically enumerated in other subheadings of Heading 3827, such as those containing other hydrofluorocarbons (HFCs) or perfluorocarbons (PFCs) in different concentrations or as the primary component. Products not containing any HFCs are also outside this scope.
What are common classification mistakes for HS 382763?
A common error is misinterpreting the "40% or more by mass" threshold for pentafluoroethane. Importers may incorrectly classify mixtures with less than 40% HFC-125 under this code, or conversely, classify pure HFC-125 as a mixture. Another mistake involves overlooking General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes. If a product meets the criteria for another, more specific heading or subheading, it should be classified there, even if it also technically fits the description of HS 382763.
How should importers classify products under HS 382763?
The correct procedure for classifying products under HS 382763 involves a two-step process. First, determine if the product is a chemical mixture or preparation not elsewhere specified. Second, ascertain the exact percentage by mass of pentafluoroethane (HFC-125) within the mixture. This requires reviewing the product's technical data sheet or Certificate of Analysis. If HFC-125 constitutes 40% or more by mass, and the product does not meet the criteria for a more specific classification, then HS 382763 is the appropriate code. Importers and customs brokers must maintain documentation supporting the composition analysis.
How is the duty calculated for products under HS 382763?
A container of R-410A refrigerant, a mixture containing approximately 50% pentafluoroethane (HFC-125) and 50% difluoromethane (HFC-32), weighing 10 kg and declared at a customs value of $150 USD, would attract a US Most Favored Nation (MFN) duty of $15.00. This is calculated using the MFN rate of 10% ad valorem, applied to the declared customs value: 10% of $150 USD = $15.00. This calculation is based on the USITC Harmonized Tariff Schedule, where such mixtures are classified under HS 3827.63.0000 with a 10% MFN duty rate.
Which trade agreements reduce duties for HS 382763?
Several free trade agreements may reduce the applicable duty rate for HS 382763, including the United States-Mexico-Canada Agreement (USMCA), which can result in a Free duty rate for qualifying goods originating from Canada or Mexico. Additionally, certain developing countries may benefit from preferential rates under the Generalized System of Preferences (GSP), potentially reducing duties to Free. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 382763, which covers other non-specified substances containing 40% or more pentafluoroethane (HFC-125)?
The Most Favored Nation (MFN) duty rate for HS code 382763 is generally 6.50% ad valorem. However, preferential duty rates are available under various trade agreements. For instance, goods originating from countries such as Australia (AU), Chile (CL), South Korea (KR), and Singapore (SG) may benefit from a duty rate of 3.7% ad valorem. Goods from certain other countries (indicated by codes like A+, BH, CO, D, E, IL, JO, MA, OM, P, PA, PE, S) may be admitted duty-free (Free). It is crucial to consult the specific tariff schedule of the importing country and verify the country of origin to determine the applicable duty rate. The United States International Trade Commission (USITC) and the EU's TARIC database are primary sources for this information.
How is the classification of HS code 382763 determined, specifically the '40% or more by mass of pentafluoroethane (HFC-125)' criterion?
The classification under HS code 382763 hinges on the quantitative composition of the product. The key criterion is that the substance must contain 40% or more, by mass, of pentafluoroethane (chemical formula C2HF5, also known as HFC-125). Importers must provide documentation, such as a Certificate of Analysis (CoA) or a manufacturer's declaration, that clearly states the percentage by mass of HFC-125 in the product. If the HFC-125 content is less than 40% by mass, or if the product falls under other more specific HS subheadings within Chapter 38, it would not be classified under 382763.
What documentation is typically required for importing goods classified under HS code 382763?
For imports classified under HS code 382763, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, to substantiate the classification and any claimed preferential duty rates, importers must provide a Certificate of Analysis (CoA) or a similar document from the manufacturer that verifies the composition, specifically confirming that the product contains 40% or more by mass of pentafluoroethane (HFC-125). If claiming preferential treatment under a Free Trade Agreement (FTA), a Certificate of Origin (COO) or a declaration of origin compliant with the specific FTA's requirements is mandatory.
Which common trade agreements offer preferential duty rates for HS code 382763, and how can importers leverage them?
Several trade agreements provide preferential duty rates for HS code 382763. For example, the United States has FTAs with countries like Australia (AU), Chile (CL), and South Korea (KR), which may offer reduced duty rates (e.g., 3.7% in some cases). Many countries also have agreements that allow for duty-free (Free) entry for goods from specific partner nations (e.g., under codes like A+, BH, CO, D, E, IL, JO, MA, OM, P, PA, PE, S, SG). To leverage these agreements, importers must ensure the goods meet the rules of origin stipulated in the relevant FTA and possess the required proof of origin, such as a compliant Certificate of Origin. Consulting the official tariff database of the importing country, such as the USITC or EU TARIC, and reviewing the specific FTA text is essential.
Can you provide a concrete example of how import duty for HS code 382763 is calculated?
Certainly. Let's assume an importer brings 1,000 kilograms of a product classified under HS code 382763 into a country where the MFN duty rate is 6.50% ad valorem. The declared value of the shipment is $15,000 USD. The duty calculation would be based on the ad valorem rate applied to the value of the goods.
Duty Amount = Value of Goods × Duty Rate Duty Amount = $15,000 USD × 6.50% Duty Amount = $15,000 USD × 0.065 Duty Amount = $975 USD
In this scenario, the import duty would be $975 USD. If the product originated from a country with a preferential duty rate of 3.7% (as indicated for some trade partners), the duty would be $15,000 USD × 3.7% = $555 USD. If it originated from a country with duty-free status, the duty would be $0 USD. It's important to note that other fees, such as customs processing fees or excise taxes, may also apply.
