HS 840733 Of a cylinder capacity exceeding 250 cm3 but not exceeding 1 000 cm3
Quick Answer: Engines of a cylinder capacity exceeding 250 cm³ but not exceeding 1,000 cm³ imported under HS 840733 enter the UK at 2.00%, the EU at 2.70%, and the US at 2.5% under the MFN rate, with some US rates being duty-free for specific trade agreements. This classification specifically applies to internal combustion piston engines, typically used in vehicles like motorcycles, cars, and light aircraft, excluding diesel engines which fall under a different heading. Importers should be aware of potential variations in duty rates based on the engine's specific application and origin country, particularly for US entry.

How to Classify This HS Code?
What products does HS 840733 cover?
This subheading covers spark-ignition internal combustion piston engines, specifically those with a cylinder capacity exceeding 250 cubic centimeters (cm3) but not exceeding 1,000 cm3. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this category includes engines designed for vehicles, motorcycles, and other machinery where the displacement falls within this specified range. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database further define these engines based on their operational characteristics and intended use, excluding those with different cylinder capacities.
What falls outside HS 840733?
The following products are excluded from HS 840733: engines with a cylinder capacity of 250 cm3 or less, or those exceeding 1,000 cm3. Additionally, diesel engines (classified under HS 8408) and electric motors are not covered by this subheading. Engines designed for specific applications, such as outboard motors (often classified elsewhere) or industrial engines with significantly different specifications, would also be classified under different HS codes, requiring careful review of their primary function and technical attributes.
What are common classification mistakes for HS 840733?
A common error is miscalculating or misinterpreting the cylinder capacity, leading to classification in an incorrect subheading. For instance, engines with a capacity just over 1,000 cm3 might be erroneously placed in 840733. Another mistake involves confusing spark-ignition engines with compression-ignition (diesel) engines, which fall under HS 8408. Importers must adhere 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, ensuring the engine's precise specifications are verified.
How should importers classify products under HS 840733?
The correct procedure for classifying engines under HS 840733 involves a multi-step verification process. Importers and customs brokers must first identify the engine's exact cylinder capacity in cubic centimeters. This information is typically found on the engine's specifications plate or in technical documentation. Subsequently, they must confirm that the engine is a spark-ignition internal combustion piston engine. Finally, they should consult the relevant national tariff schedule, such as the USITC HTS or the UK Trade Tariff, to ensure the engine's capacity falls precisely within the 250 cm3 to 1,000 cm3 range.
How is the duty calculated for products under HS 840733?
A 500 cm3 spark-ignition internal combustion piston engine, 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, as published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8407.33. The calculation is: $1,500 (declared value) × 0.05 (duty rate) = $75.00 (duty amount). This example assumes no preferential trade agreements apply.
Which trade agreements reduce duties for HS 840733?
Several free trade agreements may reduce the applicable duty rate for HS 840733, including the United States-Mexico-Canada Agreement (USMCA), which can provide duty-free entry for qualifying engines originating from Canada or Mexico. The EU's trade agreements with certain countries, such as those with Japan, may also offer reduced rates or duty-free status. To claim these preferences, documentation such as a USMCA Certificate of Origin or an EUR.1 movement certificate may be required, depending on the specific agreement and originating country.

FAQ
What are the import duty rates for HS code 840733?
The Most Favored Nation (MFN) duty rate for HS code 840733, covering spark-ignition internal combustion piston engines with a cylinder capacity exceeding 250 cm³ but not exceeding 1000 cm³, is typically 2.5% ad valorem in the United States. However, preferential duty rates apply under various trade agreements. For instance, under the USMCA, engines originating from Canada or Mexico may be eligible for free entry. Always consult the latest Harmonized Tariff Schedule of the United States (HTSUS) for the most current rates and specific country-based exceptions.
How is the cylinder capacity criterion for HS 840733 determined?
The cylinder capacity, measured in cubic centimeters (cm³), is the sole criterion for classifying engines under HS code 840733. This measurement refers to the total swept volume of all cylinders in the engine. Importers must ensure their engine's specifications clearly state this total capacity. For example, an engine with a total displacement of 750 cm³ falls within the 250 cm³ to 1000 cm³ range and would be classified here, provided it meets other conditions for the heading (e.g., spark-ignition, internal combustion, piston type).
What documentation is typically required for importing engines under HS 840733?
When importing engines classified under HS 840733, standard import documentation is required, including a commercial invoice, packing list, and bill of lading. Crucially, the commercial invoice must accurately declare the engine's cylinder capacity to substantiate the HS classification. Depending on the engine's intended use and origin, additional certifications or declarations might be necessary, such as emissions compliance certificates or proof of origin to claim preferential duty rates under trade agreements. Consult U.S. Customs and Border Protection (CBP) guidance for specific requirements.
How is the import duty for HS 840733 calculated, and can you provide an example?
The import duty for HS 840733 is generally calculated as a percentage of the declared value of the goods (ad valorem). For example, if the MFN duty rate is 2.5% and an importer brings in 10 engines valued at $500 each, the total value of the shipment is $5,000. The duty calculation would be: $5,000 (total value) × 0.025 (duty rate) = $125. This $125 would be the total duty owed. If a specific duty were applicable (e.g., per unit), the calculation would be rate × quantity. Always confirm the applicable duty basis (ad valorem or specific) with the HTSUS.
Which trade agreements commonly offer reduced or free entry for engines classified under HS 840733?
Several trade agreements can impact duty rates for HS 840733. For imports into the United States, the United States-Mexico-Canada Agreement (USMCA) often provides duty-free entry for qualifying engines originating from Canada or Mexico. Other agreements, such as those with Australia (AU), South Korea (KR), or various countries in the Middle East (e.g., Oman - OM), may offer reduced MFN rates or specific preferential rates. Importers must obtain a valid Certificate of Origin to claim benefits under these agreements and ensure the engines meet the relevant rules of origin.
