HS 850164 Of an output exceeding 750 kVA
Quick Answer: Generators of an output exceeding 750 kVA enter the UK duty-free, the EU at 2.70% ad valorem, and the US with rates varying from Free to 35% depending on the country of origin. This HS code specifically covers large-scale electrical generators, typically used in industrial settings or for backup power in substantial facilities, with a power output capacity greater than 750 kilovolt-amperes. Importers should be aware of potential preferential duty rates in the US based on trade agreements. CustomTariffs aggregates this information, highlighting the need for precise origin documentation for US entries.

How to Classify This HS Code?
What products does HS 850164 cover?
This subheading covers generators and converters of electricity, specifically those with an output exceeding 750 kVA. According to the World Customs Organization's Harmonized System Nomenclature, this category includes large-scale AC generators and AC/AC or AC/DC converters designed for substantial power generation or conversion applications. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this classification is based on the rated output capacity, distinguishing these high-capacity units from smaller electrical machinery.
What falls outside HS 850164?
The following products are excluded from HS 850164: generators and converters with an output of 750 kVA or less, which are classified under HS 850161 or 850162. Also excluded are electric motors (HS 8501), electric welders (HS 8515), and specialized power supplies or transformers (HS 8504) that do not meet the definition of a generator or converter as per Chapter 85 notes. For instance, a 500 kVA generator would be classified elsewhere, not under this specific subheading.
What are common classification mistakes for HS 850164?
A common error is misinterpreting the "output" specification, leading to the incorrect classification of units that do not exceed 750 kVA. Importers may also confuse generators with transformers or other electrical equipment. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. Ensuring the unit's rated output capacity is accurately identified and that it functions as a generator or converter is crucial for correct classification under HS 850164.
How should importers classify products under HS 850164?
The correct procedure for classifying products under HS 850164 involves a multi-step process. Importers and customs brokers must first identify the product's primary function as a generator or converter. Next, they must ascertain its rated output capacity, specifically confirming it exceeds 750 kVA. Reviewing the product's technical specifications, manufacturer's documentation, and consulting official tariff databases like the USITC HTS or EU TARIC are essential steps to ensure accurate classification.
How is the duty calculated for products under HS 850164?
A 1000 kVA synchronous AC generator, declared at a customs value of $50,000 USD, would attract a US Most Favored Nation (MFN) duty of $0. This is calculated using the MFN rate of 0% published in the USITC Harmonized Tariff Schedule for HS 850164. Therefore, the duty amount is $0 (0% × $50,000). For other jurisdictions, specific rates would apply, for example, the EU TARIC might list a rate of 1.7% ad valorem for similar goods.
Which trade agreements reduce duties for HS 850164?
Several free trade agreements may reduce the applicable duty rate for HS 850164, including the United States-Mexico-Canada Agreement (USMCA), which can lead to 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 for member countries. To claim these preferences, a valid origin declaration or certificate, such as a USMCA certification of origin, is typically required by customs authorities.

FAQ
What is the standard import duty rate for HS code 850164 (synchronous generators, of an output exceeding 750 kVA)?
The Most Favored Nation (MFN) duty rate for HS code 850164 is 2.70% ad valorem. This rate applies to imports from countries that do not have a specific preferential trade agreement with the importing country. For example, under the US Harmonized Tariff Schedule, this rate is currently in effect. Always verify the most current rates on the US International Trade Commission (USITC) website.
How is the duty calculated for HS code 850164, and can you provide an example?
The duty for HS code 850164 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if a generator classified under 850164 has a customs value of $100,000 and the MFN duty rate is 2.70%, the import duty would be $100,000 × 0.0270 = $2,700. It is crucial to ensure accurate valuation as per customs regulations.
What are the key classification criteria for HS code 850164, and what distinguishes it from other generator codes?
The primary distinguishing criterion for HS code 850164 is the output capacity of the synchronous generator. This specific code applies only to generators with an electrical output exceeding 750 kVA (kilovolt-amperes). Generators with lower output capacities would fall under different HS subheadings within 8501. Verification often involves checking the manufacturer's specifications and technical documentation to confirm the rated output.
Which trade agreements offer preferential duty rates for HS code 850164, and what documentation is needed?
Several trade agreements can provide preferential duty rates for HS code 850164. For example, imports from countries like Australia (AU), Japan (JP), or South Korea (KR) may benefit from reduced or free duty rates under specific agreements (e.g., US-Australia Free Trade Agreement, US-Japan Trade Agreement, US-Korea Free Trade Agreement). To claim these preferential rates, importers typically need to provide a Certificate of Origin or a declaration of origin issued by the exporter, demonstrating that the goods meet the rules of origin stipulated in the respective trade agreement. Always consult the specific trade agreement and the relevant customs authority for precise requirements.
Are there any specific documentation requirements beyond a Certificate of Origin for importing goods under HS code 850164?
Beyond a Certificate of Origin for preferential duty claims, importers of synchronous generators under HS code 850164 should be prepared to provide technical documentation that clearly states the generator's output capacity (in kVA), specifications, and manufacturer details. This helps customs authorities verify the correct HS classification. In some jurisdictions, safety certifications or compliance documents related to electrical equipment may also be required. Consulting the importing country's customs regulations and potentially engaging a customs broker is advisable to ensure all necessary paperwork is in order.
