HS 840729 Other
Quick Answer: Engines for marine propulsion or for the propulsion of vehicles of chapter 87 imported under HS 840729 enter the UK at 4.00%, the EU at 4.20%, and the US with rates ranging from Free to 35% ad valorem. This residual classification, "Other," applies to internal combustion piston engines for marine propulsion or for vehicles of Chapter 87 that do not fit into more specific subheadings within 8407. Importers should carefully review the specific engine type and intended use to ensure correct classification, as the US, in particular, has multiple tariff lines with varying duty rates. CustomTariffs aggregates this data, highlighting the importance of precise classification for accurate duty assessment.

How to Classify This HS Code?
What products does HS 840729 cover?
This subheading covers other spark-ignition internal combustion piston engines, specifically those not falling under the more specific categories within heading 8407. According to the WCO Harmonized System Nomenclature, this includes engines primarily used for propelling vehicles, boats, or aircraft, provided they are not classified elsewhere. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this residual category captures engines that do not fit the criteria for outboard motors (8407.21) or inboard engines (8407.22, 8407.23). It is crucial to consult the specific product's intended application and design to ensure it meets the criteria for this "other" classification.
What falls outside HS 840729?
The following products are excluded from HS 840729: spark-ignition internal combustion piston engines specifically designed as outboard motors (classified under 8407.21), inboard engines for marine propulsion (classified under 8407.22 or 8407.23), and engines for aircraft or vehicles that are classified under more specific headings within Chapter 84 or other chapters of the Harmonized System. For instance, engines for motorcycles are typically classified under 8407.34, and diesel engines, even if used in similar applications, fall under heading 8408. Therefore, engines for lawnmowers or generators, if not otherwise specified, would also be excluded from this subheading.
What are common classification mistakes for HS 840729?
A common error is misinterpreting the scope of "other" within this subheading, leading to the incorrect classification of engines that should be placed in more specific categories. For example, classifying an inboard marine engine that clearly fits the description of 8407.22 or 8407.23 under 8407.29 is a frequent mistake. This often occurs when importers do not thoroughly review the Explanatory Notes to the Harmonized System or the specific definitions provided by national tariff schedules. Adherence to General Interpretative Rule 3(c) is essential, which states that goods are to be classified under the heading which occurs last in numerical order among those which equally merit consideration, but this rule should only be applied after all more specific headings have been exhausted.
How should importers classify products under HS 840729?
The correct procedure for classifying products under HS 840729 involves a systematic approach, starting with the General Rules for the Interpretation of the Harmonized System (GRI). Importers and customs brokers must first identify the most specific heading that describes the engine based on its function, design, and intended use. If the engine is not explicitly covered by a more specific subheading within 8407, and it is a spark-ignition internal combustion piston engine for propulsion, then 8407.29 may be applicable. Consulting official tariff databases such as the USITC HTS, EU TARIC, or the UK Trade Tariff, along with the WCO Explanatory Notes, is crucial to confirm the correct classification and avoid potential penalties.
How is the duty calculated for products under HS 840729?
A 150cc spark-ignition internal combustion piston engine for a personal watercraft, declared at a customs value of $250 USD, would attract a US duty of $12.50. This is calculated using the Most Favored Nation (MFN) duty rate of 5% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: $250 (declared value) × 0.05 (duty rate) = $12.50 (duty amount). It is important to note that specific rates can vary based on country of origin and any applicable trade agreements.
Which trade agreements reduce duties for HS 840729?
Several free trade agreements may reduce the applicable duty rate for HS 840729, 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. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible goods from developing countries, such as Vietnam. To claim these preferential rates, a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries is typically required, depending on the specific jurisdiction and the terms of the agreement.

FAQ
What are the typical duty rates for HS code 840729?
HS code 840729 covers 'Other' outboard motors. Duty rates can vary significantly depending on the importing country and any applicable trade agreements. For example, under the US tariff schedule (USITC), the Most Favored Nation (MFN) duty rate is 4.20% ad valorem. However, preferential rates under trade agreements may be lower or even free. Importers should consult the specific tariff schedule of their destination country. For instance, some trade agreements might offer a 0% duty rate for qualifying products.
How is the duty for HS 840729 calculated, and can you provide an example?
The duty for HS code 840729 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For example, if a shipment of outboard motors classified under 840729 has a customs value of $10,000 and the applicable duty rate is 4.20%, the import duty would be calculated as: $10,000 (customs value) × 0.0420 (duty rate) = $420. Some countries may also apply specific duties based on weight or other units, but for 840729, ad valorem is most common.
What specific criteria distinguish goods classified under HS 840729 from other motor classifications?
HS code 840729 is a residual category for outboard motors. It applies to outboard motors not specifically covered by other headings within 8407. Generally, these are internal combustion piston engines designed to be attached to a boat's transom to provide propulsion. The key differentiator is that they are 'outboard' in design and function, meaning the engine, gearbox, and propeller are typically housed in a single, self-contained unit that mounts on the exterior of the vessel. If an engine is an inboard motor, or a sterndrive (where the engine is inside the hull but the drive unit is outside), it would fall under a different HS code.
What documentation is typically required for importing goods under HS code 840729?
Standard import documentation is required for HS code 840729, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the origin of the goods, additional documents may be necessary. This could include a certificate of origin to claim preferential duty rates under trade agreements, or specific declarations related to emissions or safety standards. Importers and customs brokers should verify the exact requirements with the customs authorities of the destination country.
Which trade agreements commonly offer preferential duty rates for HS 840729?
The availability of preferential duty rates for HS code 840729 depends entirely on the specific trade agreements between the exporting and importing countries. For example, the United States has free trade agreements (FTAs) with countries like Canada and Mexico (USMCA), and other preferential trade programs. The European Union has numerous association and free trade agreements with various countries. Similarly, the UK has its own set of trade agreements post-Brexit. To benefit from preferential rates, importers must ensure the goods meet the rules of origin stipulated in the relevant trade agreement and possess the required proof of origin documentation.
