How to Classify This HS Code?
What products does HS 840810 cover?
This subheading covers marine propulsion engines, specifically those designed for propelling watercraft. According to the World Customs Organization's Harmonized System Nomenclature, this category includes internal combustion piston engines, whether spark-ignition or compression-ignition, intended for use in ships, boats, and other vessels. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these engines are characterized by their application in marine environments, often featuring specific designs for saltwater resistance and robust operation. This includes outboard motors and inboard engines.
What falls outside HS 840810?
The following products are excluded from HS 840810: engines primarily designed for other applications, such as stationary power generation or land vehicles, even if they could theoretically be adapted for marine use. This also excludes propulsion systems that are not internal combustion engines, like electric motors for boats (typically classified under 8501) or jet propulsion units for watercraft (often found in heading 8426 or 8427). Furthermore, complete marine vessels, even if equipped with engines, are classified separately under Chapter 89.
What are common classification mistakes for HS 840810?
A common error is misclassifying engines that are part of a larger propulsion system or are intended for non-marine applications. For instance, a diesel engine intended for a generator that is then installed on a vessel might be incorrectly classified here if its primary design intent is not marine propulsion. Adherence to General Interpretative Rule 1 and 3(b) of the Harmonized System is crucial, ensuring that the essential character of the product is determined by its intended use as a marine propulsion unit, not merely its presence on a watercraft.
How should importers classify products under HS 840810?
The correct procedure for classifying marine propulsion engines under HS 840810 involves a thorough examination of the product's design, intended use, and technical specifications. Importers and customs brokers must consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and refer to explanatory notes from the WCO. Key factors include whether the engine is designed for direct marine propulsion and its power output. Verification against product literature and manufacturer declarations is essential to ensure accurate classification.
How is the duty calculated for products under HS 840810?
A 150 horsepower Yamaha F150XB outboard motor, declared at a customs value of $12,000 USD, would attract a US duty of $600.00. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: 5.0% × $12,000 USD = $600.00. This rate applies to imports from countries not benefiting from preferential trade agreements.
Which trade agreements reduce duties for HS 840810?
Several free trade agreements may reduce the applicable duty rate for HS 840810, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for eligible engines originating from Canada or Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for eligible countries. To claim these preferences, a self-certified origin statement for USMCA or a specific origin declaration for CPTPP is typically required, depending on the origin country and the specific terms of the agreement.

FAQ
What are the typical import duty rates for HS code 840810 (Marine propulsion engines) into the United States?
The standard Most Favored Nation (MFN) duty rate for marine propulsion engines under HS code 840810 into the United States is 2.5% ad valorem. However, preferential duty rates are available for goods originating from countries with which the U.S. has a Free Trade Agreement (FTA). For example, goods from Australia (AU), Chile (CL), or South Korea (KR) may enter duty-free under specific FTA provisions. It is crucial to verify the specific origin of the goods and consult the Harmonized Tariff Schedule of the United States (HTSUS) maintained by the U.S. International Trade Commission (USITC) for the most current and accurate tariff information, including any applicable quotas or special provisions.
How is the import duty for a marine propulsion engine calculated under HS 840810?
Import duty for marine propulsion engines (HS 840810) 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 marine engine valued at $50,000 is imported into the U.S. and the applicable MFN duty rate is 2.5%, the duty would be calculated as follows: $50,000 (Value) × 0.025 (Duty Rate) = $1,250 (Duty Amount). Always ensure the customs value is determined according to the WTO Valuation Agreement rules and that the correct duty rate for the country of origin is applied.
What documentation is typically required when importing marine propulsion engines under HS code 840810?
When importing marine propulsion engines (HS 840810), standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, importers must provide a declaration of origin to claim preferential duty rates under Free Trade Agreements. Depending on the engine type and its intended use, additional documentation may be necessary, such as manufacturer's specifications, certificates of conformity, or specific safety and emissions compliance certificates. Consult the importing country's customs authority (e.g., U.S. Customs and Border Protection - CBP) for a comprehensive list of required documents.
Are there specific criteria to distinguish marine propulsion engines (840810) from other types of engines?
Yes, HS code 840810 specifically covers 'Compression-ignition internal combustion piston engines' (diesel or semi-diesel) and 'Spark-ignition internal combustion piston engines' that are designed and intended for marine propulsion. Key classification criteria include the engine's primary design and intended application for use in boats, ships, or other watercraft. Engines designed for other applications, such as industrial machinery, vehicles, or electricity generation, would be classified under different HS codes. The WCO's Explanatory Notes to the Harmonized System provide detailed guidance on distinguishing between engine types and their intended uses.
Which common trade agreements offer preferential duty rates for HS 840810 imports into the U.S.?
The United States has numerous Free Trade Agreements (FTAs) that can provide preferential duty rates, often resulting in duty-free entry, for marine propulsion engines (HS 840810). Some of the most common agreements offering such benefits include those with Australia (AU), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG). To benefit from these preferential rates, importers must ensure the engines originate from a qualifying country and possess a valid Certificate of Origin or other acceptable proof of origin as stipulated by the specific trade agreement. Always refer to the USITC's HTSUS for the most up-to-date information on preferential rates and requirements.
