HS 382764 Other, not included in the subheadings above, containing 30 % or more by mass of 1,1,1,2-tetrafluoroethane (HFC-134a) but not containing unsaturated fluorinated derivatives of acyclic hydrocarbons (HFOs)
Quick Answer: Refrigerants containing 30% or more 1,1,1,2-tetrafluoroethane (HFC-134a) but no unsaturated fluorinated derivatives of acyclic hydrocarbons (HFOs) imported under HS 382764 enter the UK at 6.00%, the EU at 6.50%, and the US at 3.7% (MFN). This classification specifically applies to mixtures where HFC-134a is a significant component, excluding those with HFOs. Importers should be aware of potential variations in duty rates based on preferential trade agreements, particularly in the US where some agreements offer duty-free entry. CustomTariffs aggregates this data, highlighting the importance of verifying specific country-of-origin rules for accurate tariff application.

How to Classify This HS Code?
What products does HS 382764 cover?
This subheading covers mixtures and other preparations containing 30% or more by mass of 1,1,1,2-tetrafluoroethane (HFC-134a) that do not contain unsaturated fluorinated derivatives of acyclic hydrocarbons, commonly known as hydrofluoroolefins (HFOs). According to the World Customs Organization's Harmonized System Nomenclature, these are typically refrigerant blends or specialized chemical formulations where HFC-134a is the primary component by weight, and they are not classified under more specific subheadings within heading 3827. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database provide further detail on the specific chemical composition and intended use for precise classification.
What falls outside HS 382764?
The following products are excluded from HS 382764: mixtures containing less than 30% by mass of 1,1,1,2-tetrafluoroethane (HFC-134a), or those that contain unsaturated fluorinated derivatives of acyclic hydrocarbons (HFOs), even if HFC-134a is present. Pure HFC-134a itself is classified under a different subheading. Additionally, products where HFC-134a is not the predominant fluorinated hydrocarbon component, or where other chemical compounds are present in higher concentrations, would also fall outside this specific classification. For instance, refrigerant blends primarily composed of HFOs would be classified elsewhere.
What are common classification mistakes for HS 382764?
A common error is misinterpreting the percentage threshold for 1,1,1,2-tetrafluoroethane (HFC-134a) or failing to identify the presence of unsaturated fluorinated derivatives of acyclic hydrocarbons (HFOs). Importers may incorrectly classify mixtures containing less than 30% HFC-134a under this code, or overlook the exclusion criteria related to HFOs. According to General Rule of Interpretation (GRI) 3(b) of the Harmonized System, mixtures are often classified by their essential character, which in this case is heavily dictated by the specific percentage of HFC-134a and the absence of HFOs.
How should importers classify products under HS 382764?
The correct procedure for classifying products under HS 382764 involves a detailed analysis of the product's chemical composition. Importers and customs brokers must obtain a precise breakdown of all constituent chemicals, specifically verifying the mass percentage of 1,1,1,2-tetrafluoroethane (HFC-134a). Crucially, they must also confirm the absence of unsaturated fluorinated derivatives of acyclic hydrocarbons (HFOs). Consulting the Safety Data Sheet (SDS) and the manufacturer's technical specifications is paramount to ensure accurate declaration and compliance with customs regulations.
How is the duty calculated for products under HS 382764?
A shipment of 100 kilograms of "R-134a Refrigerant Blend," declared at a customs value of $500 USD, would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7% ad valorem, applied to the declared customs value ($500 USD × 0.07 = $35.00). This calculation is based on the USITC Harmonized Tariff Schedule, where this specific type of refrigerant blend, meeting the criteria of HS 382764, is subject to this rate. Always verify the current MFN rate for your specific import destination.
Which trade agreements reduce duties for HS 382764?
Several free trade agreements may reduce the applicable duty rate for HS 382764, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada and Mexico can enter the United States duty-free. To claim this preference, a valid USMCA country of origin certification statement is required. While not directly applicable to this specific chemical classification for all countries, general GSP (Generalized System of Preferences) provisions might apply to certain developing nations, potentially offering reduced rates, requiring a GSP Form A for documentation.

FAQ
What are the typical import duty rates for HS code 382764, and how do preferential rates apply?
For HS code 382764, the Most Favored Nation (MFN) duty rate is generally 6.00% ad valorem. However, preferential rates can significantly reduce this. For example, under certain trade agreements, countries like Australia (AU), Chile (CL), South Korea (KR), and Singapore (SG) may benefit from a Free (0%) duty rate. It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the origin of the goods and the relevant Free Trade Agreement (FTA).
What are the key classification criteria for goods under HS code 382764?
To be classified under HS code 382764, a product must meet two primary criteria: 1) It must be a mixture or product not specified in preceding subheadings within Chapter 38. 2) It must contain 30% or more by mass of 1,1,1,2-tetrafluoroethane (HFC-134a). 3) Crucially, it must not contain unsaturated fluorinated derivatives of acyclic hydrocarbons, commonly known as Hydrofluoroolefins (HFOs). Verification of the product's composition, particularly the percentage of HFC-134a and the absence of HFOs, is essential for correct classification.
What documentation is typically required for importing goods classified under HS code 382764?
Standard import documentation for HS code 382764 includes a commercial invoice, packing list, and bill of lading or air waybill. Additionally, a Certificate of Origin is often required to claim preferential duty rates under FTAs. Depending on the importing country's regulations and the specific nature of the product (e.g., if it's considered a refrigerant or a chemical with environmental implications), further documentation such as a Safety Data Sheet (SDS) or specific import permits related to ozone-depleting substances or greenhouse gases might be necessary. Always check the importing country's customs authority for precise requirements.
How is the import duty calculated for HS code 382764, and can you provide an example?
The import duty for HS code 382764 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 customs value of a shipment is $10,000 USD, the duty would be calculated as: $10,000 USD (Customs Value) × 0.06 (Duty Rate) = $600 USD (Import Duty). If the product were eligible for a Free (0%) preferential rate, the duty would be $0 USD.
Which common trade agreements offer preferential duty rates for HS code 382764, and what is the general outcome?
Several trade agreements provide preferential duty rates for goods classified under HS code 382764. Examples include agreements with Australia (AU), Chile (CL), Colombia (CO), South Korea (KR), and Singapore (SG). Under these agreements, the duty rate is often reduced to Free (0% ad valorem). Importers and customs brokers must ensure that the goods meet the rules of origin stipulated in the respective FTA to qualify for these reduced rates. Consulting the specific tariff schedule for the importing country, often accessible through official government trade websites like the USITC or EU TARIC, is essential for confirming eligibility and specific rate reductions.
