HS 850161 AC generators (alternators), other than photovoltaic generators
Quick Answer: AC generators, other than photovoltaic generators, imported under HS 850161 enter the UK duty-free, the EU at 2.70% ad valorem, and the US at 2.5% ad valorem under the MFN rate. This classification covers alternators, which are machines that convert mechanical energy into alternating current electrical energy, excluding those that generate electricity directly from sunlight. Importers should be aware of potential variations in duty rates based on preferential trade agreements, particularly for US entries where numerous countries benefit from duty-free access. CustomTariffs aggregates this data, highlighting the importance of verifying specific country-of-origin rules for accurate duty assessment.

How to Classify This HS Code?
What products does HS 850161 cover?
This subheading covers AC generators (alternators) with a power output not exceeding 75 kVA. According to the World Customs Organization's Harmonized System Nomenclature, this category specifically excludes photovoltaic generators. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these are machines that convert mechanical energy into alternating current electrical energy, with a defined power capacity limit. This includes a wide range of generators used in various applications, from small portable units to those powering backup systems.
What falls outside HS 850161?
The following products are excluded from HS 850161: AC generators with a power output exceeding 75 kVA, which are classified under HS 850162 or 850163 depending on their capacity. Photovoltaic generators, which convert sunlight directly into electricity, are classified under HS 850180. Additionally, DC generators (dynamos) are classified under HS 850110 or 850120. Motors, which convert electrical energy into mechanical energy, are also classified under different headings within 8501, such as 850131 for DC motors up to 750 W.
What are common classification mistakes for HS 850161?
A common error is misinterpreting the power output threshold of 75 kVA. Importers may incorrectly classify generators exceeding this limit under 850161, or conversely, classify smaller units under higher-capacity subheadings. This often stems from a lack of precise technical specifications or a misunderstanding of the unit of measurement (kVA vs. kW). Following General Rule of Interpretation (GRI) 1, the classification is determined by the terms of the heading and any relative section or chapter notes, ensuring the power output is accurately verified against the official definitions.
How should importers classify products under HS 850161?
The correct procedure for classifying AC generators under HS 850161 involves several key steps. First, identify the product's primary function as an AC generator. Second, determine its power output in kVA. If the output is 75 kVA or less, and it is not a photovoltaic generator, then HS 850161 is likely applicable. Importers and customs brokers must consult the official tariff schedule of the importing country (e.g., USITC HTS, EU TARIC) and review the specific wording of the subheading and any relevant explanatory notes or rulings to confirm the classification.
How is the duty calculated for products under HS 850161?
A 10 kVA portable AC generator, declared at a customs value of $1,500 USD, would attract a US duty of $75.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value. The calculation is: 5.0% × $1,500 = $75.00. This rate is published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) under subheading 850161.0000. Note that specific importations may be subject to additional duties or taxes.
Which trade agreements reduce duties for HS 850161?
Several free trade agreements may reduce the applicable duty rate for HS 850161, including the United States-Mexico-Canada Agreement (USMCA), which can offer duty-free entry for qualifying goods originating from Canada or Mexico. The EU's Generalized Scheme of Preferences (GSP) can also provide reduced or free entry for goods from certain developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a EUR.1 movement certificate for EU preferences, depending on the specific agreement and importing jurisdiction.

FAQ
What are the typical import duty rates for HS code 850161 (AC generators, other than photovoltaic)?
The Most Favored Nation (MFN) duty rate for HS code 850161 can vary by country. For example, the United States applies a 0.00% MFN duty rate. The European Union, under the TARIC system, also generally has a 0.00% duty rate for most AC generators of this type. The United Kingdom's Trade Tariff typically lists a 0.00% duty rate. However, it is crucial to verify the specific rate for the importing country and the origin of the goods, as preferential rates under trade agreements can differ significantly. Always consult the official tariff schedule of the importing country for the most accurate and up-to-date information.
How is the duty for HS code 850161 calculated, and can you provide an example?
The duty calculation for HS code 850161 typically depends on whether the duty is ad valorem (a percentage of the value) or specific (a fixed amount per unit). If the duty is ad valorem, the calculation is: Duty = (Customs Value of Goods) × (Ad Valorem Duty Rate). For example, if an AC generator valued at $10,000 is imported into a country with a 2.70% ad valorem duty rate, the duty would be $10,000 × 0.0270 = $270. If the duty is specific, the calculation is: Duty = (Quantity of Goods) × (Specific Duty Rate per Unit). Always refer to the specific tariff entry for the applicable duty basis and rate.
What are the key classification criteria for HS code 850161, and what distinguishes it from other generator codes?
HS code 850161 specifically covers 'AC generators (alternators), other than photovoltaic generators'. The primary classification criteria are that the machine must generate alternating current (AC) and must not be a photovoltaic generator (which converts light directly into electricity and falls under HS code 8541.43). This code includes alternators, which are a type of AC generator commonly found in vehicles and power generation systems. It excludes DC generators (HS code 8501.40) and complete photovoltaic power generators (HS code 8501.62).
What common trade agreements offer preferential duty rates for HS code 850161, and how can importers benefit?
Many trade agreements provide preferential duty rates for goods classified under HS code 850161. For instance, under the USMCA (United States-Mexico-Canada Agreement), goods originating from Canada or Mexico may benefit from duty-free entry into the United States. Similarly, agreements like the EU's with various partner countries (e.g., EFTA, Turkey) often reduce or eliminate duties. To benefit, importers must ensure the AC generators meet the rules of origin stipulated in the relevant trade agreement and possess the necessary proof of origin documentation, such as a certificate of origin or a declaration on the invoice, as required by the importing country's customs authority.
What documentation is typically required for importing AC generators under HS code 850161?
Standard import documentation for HS code 850161 generally includes a commercial invoice, a packing list, and a bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be required to claim preferential duty rates under a trade agreement. Importers should also be prepared to provide technical specifications or datasheets for the AC generator to confirm its classification and compliance with any national standards or safety regulations. It is advisable to consult the customs authority of the importing country or a customs broker for a comprehensive list of required documents.
