HS 382751 Containing trifluoromethane (HFC-23) or perfluorocarbons (PFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs)
Quick Answer: Products containing trifluoromethane (HFC-23) or perfluorocarbons (PFCs), but not chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), imported under HS 382751 enter the UK at 6.00%, the EU at 6.50%, and the US at 3.7% (MFN). This classification applies to various fluorinated gases and mixtures used in refrigeration, air conditioning, and as propellants, excluding those with CFCs or HCFCs. Importers should be aware of potential environmental regulations and specific country restrictions beyond standard tariffs. CustomTariffs aggregates this data, highlighting the varying duty rates across major trading blocs, necessitating careful planning for international shipments.

How to Classify This HS Code?
What products does HS 382751 cover?
This subheading covers mixtures and preparations containing trifluoromethane (HFC-23) or perfluorocarbons (PFCs), provided they do not contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). According to the World Customs Organization's Harmonized System Nomenclature, these are typically used as refrigerants, propellants, or fire extinguishing agents. For instance, specific blends designed for refrigeration systems that exclusively feature HFC-23 or PFCs fall under this classification, as confirmed by the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database.
What falls outside HS 382751?
The following products are excluded from HS 382751: any mixtures containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), even if they also contain trifluoromethane or perfluorocarbons. Products that are solely trifluoromethane or perfluorocarbons in their pure form, without being part of a mixture or preparation, are classified under their respective headings. For example, pure HFC-23 is classified elsewhere, and mixtures containing even small amounts of HCFCs would be directed to a different subheading within heading 3827.
What are common classification mistakes for HS 382751?
A common error is misinterpreting the exclusion of CFCs and HCFCs. Importers may mistakenly classify a mixture containing these prohibited substances under 382751 if they focus solely on the presence of HFC-23 or PFCs. This violates General Interpretative Rule 1, which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Accurate identification of all components within the mixture is crucial, and a product containing even 0.1% of an HCFC would not qualify for this subheading.
How should importers classify products under HS 382751?
The correct procedure for classifying products under HS 382751 involves a thorough analysis of the product's composition. Importers and customs brokers must obtain a detailed list of all chemical constituents and their concentrations from the manufacturer. This information should then be cross-referenced with the WCO HS Explanatory Notes and national tariff schedules, such as the UK Trade Tariff, to confirm the absence of CFCs and HCFCs and the presence of HFC-23 or PFCs. A declaration of the exact chemical composition is essential for accurate customs clearance.
How is the duty calculated for products under HS 382751?
A 100 kg cylinder of R-410A refrigerant, declared at a customs value of $500 USD, would attract a US duty of $50.00. This is calculated using the Most Favored Nation (MFN) duty rate of 10% ad valorem, applied to the declared customs value ($500 USD × 10% = $50.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 3827.61.00, which covers similar refrigerant mixtures not containing CFCs or HCFCs.
Which trade agreements reduce duties for HS 382751?
Several free trade agreements may reduce the applicable duty rate for HS 382751. For instance, under the United States-Mexico-Canada Agreement (USMCA), qualifying products originating from Canada or Mexico may enter the US duty-free. Similarly, products originating from countries benefiting from the US Generalized System of Preferences (GSP) program may also receive preferential duty rates, potentially "Free." To claim these preferences, a valid USMCA Certificate of Origin or a GSP Form A, respectively, is typically required by US Customs and Border Protection.

FAQ
What are the primary classification criteria for HS code 3827.51?
HS code 3827.51 specifically covers mixtures containing trifluoromethane (HFC-23) or perfluorocarbons (PFCs). Crucially, these mixtures must not contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Importers must ensure their product's chemical composition aligns with these specific fluorinated compounds to correctly classify under this heading. Verification often requires a Safety Data Sheet (SDS) or a Certificate of Analysis (CoA) detailing the chemical constituents and their concentrations.
What are the typical Most Favored Nation (MFN) duty rates for HS code 3827.51?
The Most Favored Nation (MFN) duty rate for HS code 3827.51 is generally 6.00% ad valorem. However, it's essential to consult the most current tariff schedule for the importing country, as rates can be subject to change. For the United States, the Harmonized Tariff Schedule (USHTS) is the definitive source. For the European Union, the TARIC database provides detailed duty information.
How do preferential trade agreements affect the duty rates for HS code 3827.51?
Many preferential trade agreements offer reduced or free duty rates for goods classified under HS code 3827.51. For example, under agreements like the USMCA (United States-Mexico-Canada Agreement), or agreements with countries such as Australia (AU), South Korea (KR), or Singapore (SG), the duty rate can be Free. To claim preferential treatment, importers must provide a valid Certificate of Origin and ensure the goods meet the rules of origin stipulated in the respective trade agreement. Always verify the specific preferential rate applicable to your country of origin and destination.
How is the import duty for HS code 3827.51 calculated, and can you provide an example?
The duty for HS code 3827.51 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 6.00% and the declared customs value of a shipment is $10,000 USD, the import duty would be calculated as: $10,000 (Value) × 0.06 (Duty Rate) = $600 USD. Some specific trade agreements might introduce specific duties or other charges, so always confirm the applicable duty calculation method.
What documentation is typically required for importing products under HS code 3827.51?
Beyond standard import documentation such as a commercial invoice, packing list, and bill of lading, importing products under HS code 3827.51 often requires specific chemical documentation. This may include a Safety Data Sheet (SDS) or a Certificate of Analysis (CoA) to substantiate the chemical composition and confirm the absence of CFCs and HCFCs. If claiming preferential duty rates, a valid Certificate of Origin is mandatory. Importers should also be aware of any environmental regulations or specific import licenses that might apply to fluorinated gases in the destination country.
