HS 382739 Other
Quick Answer: Chemical products not elsewhere specified under HS code 382739 enter the UK at 6.00%, the EU at 6.50%, and the US at a range of rates from Free to 25%, depending on the country of origin. This residual classification applies to chemical mixtures or products that do not fit into more specific headings within Chapter 38 of the Harmonized System. Importers should carefully verify the precise composition of their goods to ensure correct classification, as misclassification can lead to incorrect duty assessments. According to CustomTariffs data, the varying US duty rates highlight the importance of understanding preferential trade agreements.

How to Classify This HS Code?
What products does HS 382739 cover?
This subheading covers "Other" mixtures and preparations based on refrigerants not specified elsewhere in heading 3827. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this residual category captures refrigerant mixtures that do not fit into the more specific subheadings of 3827. For instance, in the US Harmonized Tariff Schedule (HTS), it encompasses blends of hydrofluorocarbons (HFCs) or hydrochlorofluorocarbons (HCFCs) with other substances, provided they are not specifically classified under 3827.10 to 3827.32.
What falls outside HS 382739?
The following products are excluded from HS 382739: pure refrigerants classified under their specific chemical names (e.g., R-134a under 2903.39), refrigerants that are part of a finished product (e.g., a refrigerator), or mixtures primarily intended for purposes other than refrigeration. For example, a cleaning solvent containing a small amount of refrigerant would likely be classified based on its primary function, not as a refrigerant mixture. Products classified under 3827.10 (mixtures of halogenated derivatives of methane or ethane) or 3827.31 (mixtures containing chlorofluorocarbons (CFCs)) are also excluded.
What are common classification mistakes for HS 382739?
A common error is misinterpreting the "other" designation, leading to the classification of products that should fall under more specific subheadings within heading 3827 or even in other chapters of the Harmonized System. For example, classifying a simple blend of two HFCs under 3827.39 when a more specific subheading for mixtures of halogenated derivatives of methane or ethane exists. Importers may also fail to consider the primary use or composition of the mixture, incorrectly classifying it as a refrigerant when its main function is different, contrary to General Rule of Interpretation (GRI) 3(b) for mixtures and composite goods.
How should importers classify products under HS 382739?
The correct procedure for classifying products under HS 382739 involves a thorough analysis of the product's composition and intended use, referencing the WCO Explanatory Notes and national tariff schedules like the US HTS or EU TARIC. Importers must first determine if the product is a mixture or preparation based on refrigerants. If it is, they should then check if it fits any of the more specific subheadings within heading 3827. Only if the product does not meet the criteria for any other subheading within 3827 should it be considered for classification under 3827.39.
How is the duty calculated for products under HS 382739?
A 500 kg shipment of a refrigerant blend containing hydrofluorocarbons, declared at a customs value of $2,500 USD, would attract a US duty of $125.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5% ad valorem, applied to the declared customs value ($2,500 USD × 0.05 = $125.00). This calculation is based on the duty rates published in the USITC Harmonized Tariff Schedule for subheading 3827.39.90.
Which trade agreements reduce duties for HS 382739?
Several free trade agreements may reduce the applicable duty rate for HS 382739, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating goods from Canada or Mexico can enter the United States duty-free. To claim this preferential rate, a self-certified origin statement is typically required, detailing the product's origin and compliance with the agreement's rules of origin. Other agreements, such as those with developing countries under the Generalized System of Preferences (GSP), may also offer reduced or duty-free access, often requiring a GSP Form A.

FAQ
What are the typical import duty rates for HS code 3827.39, and how do preferential rates apply?
For HS code 3827.39, the Most Favored Nation (MFN) duty rate is typically 6.00%. However, significant preferential rates are available under various trade agreements. For instance, goods originating from countries like Australia (AU), Canada (CA), Chile (CL), South Korea (KR), and Singapore (SG) may benefit from duty rates as low as Free. It is crucial to verify the specific preferential rate applicable to your country of origin and ensure you have the necessary proof of origin documentation to claim these benefits. Always consult the latest tariff schedules of the importing country for precise rates.
What specific criteria determine if a product falls under HS code 3827.39, described as 'Other'?
HS code 3827.39 is a residual category for 'Other' mixtures and products of chemicals not elsewhere specified or included in Chapter 38. Classification under this code requires that the product is a mixture or preparation of chemicals and does not fit into any of the more specific subheadings within Chapter 38 (e.g., refrigerants, anti-knock preparations, combustion-initiating fluids, or solvents and thinners for varnishes and paints). Importers must conduct a thorough analysis of the product's composition and intended use to confirm it is not classifiable under a more precise HS code before assigning 3827.39.
What documentation is typically required for importing goods classified under HS code 3827.39?
When importing goods under HS code 3827.39, standard import documentation is generally required, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the specific chemical nature of the product and the importing country's regulations, additional documentation may be necessary. This could include a Safety Data Sheet (SDS) to detail the chemical hazards, a Certificate of Origin to support preferential duty claims, and potentially specific import permits or licenses if the chemicals are regulated substances. Always check with the customs authority of the destination country for a comprehensive list.
How is the import duty calculated for a product classified under HS code 3827.39, and can you provide an example?
The import duty for HS code 3827.39 is typically calculated on an ad valorem basis, meaning it's a percentage of the customs value of the goods. For example, if the MFN duty rate is 6.00% and you import a shipment with a customs value of $10,000 USD, the import duty would be calculated as: $10,000 USD (Customs Value) × 0.06 (6.00% duty rate) = $600 USD. If the duty were based on a specific rate (e.g., per kilogram), the calculation would be rate per unit × quantity. Always ensure the customs value is correctly determined according to international valuation rules.
Which major trade agreements offer preferential duty rates for HS code 3827.39, and what are the general requirements to benefit?
Several trade agreements provide preferential duty rates for HS code 3827.39. Notably, agreements such as the USMCA (United States-Mexico-Canada Agreement), CPTPP (Comprehensive and Progressive Agreement for Trans-Pacific Partnership), and various bilateral agreements (e.g., with South Korea, Chile, Singapore) often list reduced or free duty rates for products within this heading. To benefit, importers must typically provide a valid Certificate of Origin issued by the exporter or producer, demonstrating that the goods meet the rules of origin stipulated in the specific trade agreement. The exact requirements and applicable rates should be confirmed for each agreement and importing country.
