How to Classify This HS Code?
What products does HS 850231 cover?
This subheading covers other generating sets, specifically those powered by reciprocating internal combustion piston engines, with a power output not exceeding 75 kVA. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes portable and stationary generating sets designed for various applications, such as backup power, construction sites, and recreational use, provided they meet the specified power output threshold and are driven by the defined engine type. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC also define this category based on the engine type and power output.
What falls outside HS 850231?
The following products are excluded from HS 850231: generating sets powered by other prime movers (e.g., gas turbines, wind turbines), those exceeding 75 kVA power output, and generating sets that are integral parts of larger machinery or vehicles. For instance, a ship's onboard generator exceeding the kVA limit would be classified elsewhere, as would a portable generator that is primarily designed to be a component of a specific piece of equipment, rather than a standalone power source.
What are common classification mistakes for HS 850231?
A common error is misinterpreting the power output threshold of 75 kVA, leading to the misclassification of slightly larger generating sets. Another mistake involves confusing these generating sets with other electrical machinery under Chapter 85, such as transformers or uninterruptible power supplies (UPS), which have distinct classifications. Adherence to General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes, is crucial.
How should importers classify products under HS 850231?
The correct procedure for classifying products under HS 850231 involves a multi-step process. Importers and customs brokers must first identify the prime mover (reciprocating internal combustion piston engine) and then determine the maximum continuous power output in kVA. Consulting the official tariff schedule, such as the USITC HTS or EU TARIC, and reviewing the explanatory notes for heading 8502 is essential to confirm that the product aligns with the description of "other generating sets" within the specified power limit.
How is the duty calculated for products under HS 850231?
A portable gasoline generator with a rated output of 5 kVA, declared at a customs value of $800 USD, would attract a US duty. Assuming a Most Favored Nation (MFN) duty rate of 3.5% ad valorem as published in the USITC Harmonized Tariff Schedule, the duty would be calculated as 3.5% of $800, resulting in a duty amount of $28.00 USD. This calculation is based on the declared value and the applicable MFN tariff rate for HS code 850231.
Which trade agreements reduce duties for HS 850231?
Several free trade agreements may reduce the applicable duty rate for HS 850231, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, qualifying goods originating from Canada or Mexico may receive a duty rate of Free. To claim this preference, a self-certified origin statement on the commercial invoice or a separate certificate of origin is typically required. Other agreements, like the Generalized System of Preferences (GSP), may offer reduced rates for eligible developing countries, often requiring a GSP Form A.

FAQ
What are the typical import duty rates for HS code 8502.31?
HS code 8502.31, covering 'Other generating sets' (specifically those with a power not exceeding 7.5 kVA and driven by spark-ignition internal combustion piston engines), has varying duty rates depending on the importing country and trade agreements. For example, the U.S. Most Favored Nation (MFN) rate is 0.00%. In the European Union, under the TARIC system, the rate can be 2.5% ad valorem. The United Kingdom's Trade Tariff also lists a duty rate of 2.5% ad valorem. Importers should always verify the specific rate for their destination country and any applicable preferential agreements.
How is HS code 8502.31 classified? What are the key criteria?
HS code 8502.31 is classified for generating sets that are powered by spark-ignition internal combustion piston engines and have an output not exceeding 7.5 kVA. Key classification criteria include the type of engine (spark-ignition, internal combustion, piston), the output power capacity (not exceeding 7.5 kVA), and the function as a generating set (producing electrical energy). Items like portable generators used for recreational purposes or backup power, falling within this power range and engine type, would typically be classified here. It's crucial to distinguish these from generating sets driven by other engine types (e.g., diesel) or those with higher power outputs, which fall under different subheadings.
Which trade agreements commonly offer preferential duty rates for HS code 8502.31?
Several trade agreements can provide preferential duty rates for goods classified under HS code 8502.31. For instance, under the U.S. Generalized System of Preferences (GSP), certain developing countries may receive duty-free entry. Agreements like the EU's Economic Partnership Agreements (EPAs) or Free Trade Agreements (FTAs) with countries such as Canada (CUSMA) or Mexico (USMCA) can also reduce or eliminate duties. For example, goods originating from Australia (AU), Canada (C), or Mexico (M) might benefit from preferential rates under specific bilateral agreements. Importers must ensure they have the necessary proof of origin documentation to claim these benefits.
How is the import duty for HS code 8502.31 calculated? Can you provide an example?
The import duty for HS code 8502.31 is typically calculated as a percentage of the declared customs value of the goods (ad valorem duty). For example, if a country applies a 2.5% ad valorem duty rate and an importer declares a shipment of generating sets under HS 8502.31 with a total customs value of $10,000, the duty calculation would be: $10,000 (Customs Value) × 2.5% (Duty Rate) = $250 (Import Duty). Some countries may also apply specific duties (per unit) or a combination of ad valorem and specific duties, though ad valorem is common for this code. Always confirm the duty calculation method with the destination country's customs authority.
What documentation is typically required for importing goods under HS code 8502.31?
When importing generating sets classified under HS code 8502.31, standard documentation includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list specifying the contents of each package; and a bill of lading or air waybill as proof of shipment. Crucially, a certificate of origin is often required to determine eligibility for preferential duty rates under trade agreements. Depending on the importing country and the specific product, additional documents like safety certifications (e.g., CE marking for the EU, UL listing for the US) or import permits may be necessary to ensure compliance with local regulations and standards.
