HS 850780 Other accumulators
Quick Answer: Other accumulators imported under HS 850780 enter the EU at 2.70%, the UK at 0.00%, and the US at 3.4% or free for qualifying trade agreements. This classification encompasses a broad range of rechargeable electric accumulators not specifically listed in other headings within Chapter 85, such as certain types of nickel-cadmium, nickel-metal hydride, and lithium-ion batteries that do not fit more precise subheadings. Importers should carefully verify the specific chemistry and application of their accumulators to ensure correct classification, as variations can lead to different duty rates and potential trade restrictions.

How to Classify This HS Code?
What products does HS 850780 cover?
This subheading covers "Other accumulators," which are electrical energy storage devices not specifically classified elsewhere within HS 8507. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes and definitions found in official tariff schedules like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database, this category includes accumulators such as nickel-cadmium, nickel-metal hydride, and lithium-ion batteries that do not fit into more specific subheadings like those for lead-acid accumulators or lithium-ion accumulators of a particular type or voltage. It is a residual category for various rechargeable battery technologies.
What falls outside HS 850780?
The following products are excluded from HS 850780: primary (non-rechargeable) batteries, which are classified under HS 8506; lead-acid accumulators, classified under HS 850710; and specific types of lithium-ion accumulators that have their own dedicated subheadings, such as those for portable computers or mobile phones if they are designed for those specific devices. Batteries that are integral components of a larger machine and cannot be readily removed or replaced are also typically classified with the machine itself, not as separate accumulators.
What are common classification mistakes for HS 850780?
A common error is misclassifying specific types of lithium-ion batteries that have dedicated subheadings under HS 8507, such as those for electric vehicles or energy storage systems, into the residual "other" category. Importers may also incorrectly classify primary batteries (non-rechargeable) under this heading, whereas they belong to HS 8506. Adherence to General Interpretative Rule 3(c) of the Harmonized System, which states that goods should be classified to the heading which occurs last in numerical order among those which equally merit consideration, is crucial for accurate classification.
How should importers classify products under HS 850780?
The correct procedure for classifying accumulators under HS 850780 involves a detailed examination of the product's technical specifications and intended use. Importers and customs brokers must first consult the WCO Harmonized System Explanatory Notes and the specific tariff schedule of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff). If the accumulator is rechargeable and not specifically covered by a more precise HS code within heading 8507, then HS 850780 is likely the appropriate classification. Verification of the battery chemistry (e.g., NiCd, NiMH, Li-ion) and its specific application is paramount.
How is the duty calculated for products under HS 850780?
A pack of 10 Nickel-Metal Hydride (NiMH) rechargeable batteries, weighing 0.5 kg and declared at a customs value of $50 USD, would attract a US duty of $0.00. This is because the Most Favored Nation (MFN) duty rate for HS 850780 in the USITC Harmonized Tariff Schedule is 0% ad valorem. Therefore, the duty calculation is 0% × $50 USD = $0.00 USD. This rate is applicable for goods imported from countries not benefiting from preferential trade agreements.
Which trade agreements reduce duties for HS 850780?
Several free trade agreements may reduce the applicable duty rate for HS 850780, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada or Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, potentially Free, for qualifying goods from member countries like Vietnam. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a specific certificate of origin for other agreements, depending on the jurisdiction and the specific trade pact.

FAQ
What are the typical import duty rates for HS code 850780, 'Other accumulators'?
The Most Favored Nation (MFN) duty rate for HS code 850780, 'Other accumulators,' can vary. For instance, under the US tariff schedule, the MFN rate is 0.00%. In contrast, the EU's TARIC system may list rates such as 2.70% ad valorem. The UK Trade Tariff also shows a standard rate of 0.00% for this code. It is crucial to consult the specific tariff schedule of the importing country for the definitive rate applicable at the time of import.
How is HS code 850780 defined, and what types of accumulators fall under 'Other accumulators'?
HS code 850780 covers accumulators (storage batteries) not specifically listed under other headings within Chapter 85, such as lead-acid accumulators (8507.10) or nickel-cadmium, nickel-metal hydride, and lithium-ion accumulators (8507.60 and 8507.70). 'Other accumulators' typically include those utilizing chemistries not explicitly enumerated, such as sodium-sulfur batteries, zinc-air batteries, or other advanced or less common rechargeable battery technologies. Classification relies on the specific electrochemical system and construction of the accumulator.
What preferential duty rates are available for HS code 850780 under trade agreements, and how can importers claim them?
Many trade agreements offer preferential duty rates for goods classified under HS 850780. For example, under the US tariff schedule, preferential rates can be as low as Free (0.00%) for imports from countries like Australia (AU), Canada (C), Japan (JP), and South Korea (KR), provided the goods meet the rules of origin stipulated in the respective Free Trade Agreements (FTAs). To claim these rates, importers must possess a valid Certificate of Origin or other acceptable proof of origin documentation as required by the importing country's customs authority and the specific FTA. Documentation must be presented at the time of import or within a specified timeframe thereafter.
How is the import duty for HS code 850780 calculated, and can you provide an example?
The calculation of import duty for HS code 850780 depends on whether the duty is assessed as an ad valorem rate (a percentage of the value) or a specific rate (a fixed amount per unit). If the applicable duty rate is ad valorem, the calculation is: Duty Amount = (Customs Value of Goods × Duty Rate). For example, if the MFN duty rate is 2.70% and the customs value of the imported 'other accumulators' is $10,000, the duty would be $10,000 × 0.0270 = $270. If a specific duty rate applies (e.g., $5 per unit), the calculation would be: Duty Amount = Quantity of Units × Specific Duty Rate. Always verify the exact basis of duty assessment (ad valorem, specific, or a combination) from the importing country's tariff schedule.
Are there any specific documentation requirements beyond a commercial invoice and packing list for importing goods under HS code 850780?
While a commercial invoice, packing list, and bill of lading are standard, importing 'other accumulators' under HS code 850780 may require additional documentation. Depending on the country of import and the specific type of accumulator, this could include a Certificate of Origin (especially if claiming preferential treatment), safety certifications (e.g., compliance with electrical safety standards like UL or CE marking), or declarations regarding the battery chemistry and disposal/recycling compliance. Importers should consult the importing country's customs regulations and the relevant government agencies (e.g., environmental protection agencies) to ensure all necessary documentation is in order to avoid delays or penalties.
