How to Classify This HS Code?
What products does HS 840610 cover?
This subheading covers turbines specifically designed for the propulsion of marine vessels. According to the World Customs Organization's Harmonized System Nomenclature, this includes steam turbines, gas turbines, and other types of turbines intended for use in ships, boats, and other watercraft. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these are prime movers generating mechanical power for the direct or indirect propulsion of maritime craft, excluding auxiliary machinery not directly involved in propulsion.
What falls outside HS 840610?
The following products are excluded from HS 840610: turbines intended for land-based power generation, industrial machinery, or aircraft propulsion. For instance, gas turbines used in power plants would be classified under heading 8406, but not this specific subheading. Similarly, turbines for auxiliary marine functions, such as pumps or generators not directly linked to propulsion, would fall under different HS codes. It is crucial to distinguish between propulsion turbines and other types of turbines used on vessels.
What are common classification mistakes for HS 840610?
A common error is misclassifying turbines that are part of a complete propulsion system but are not the primary prime mover. For example, a gearbox or propeller shaft that is supplied with a turbine but is a separate component might be incorrectly included. According to General Rule of Interpretation (GRI) 3(b), goods consisting of different materials or components which cannot be readily separated are classified as if they consisted of the material or component which gives them their essential character. Turbines for marine propulsion are the essential character.
How should importers classify products under HS 840610?
The correct procedure for classifying turbines for marine propulsion involves a thorough examination of the product's intended use and design. Importers and customs brokers must consult the official tariff schedules of the importing country, such as the USITC HTS or the UK Trade Tariff. Verify that the turbine is explicitly designed and manufactured for marine propulsion. Review technical specifications and product literature to confirm its application, ensuring it is not intended for other uses like land-based power generation.
How is the duty calculated for products under HS 840610?
A marine gas turbine engine, model LM2500, weighing 5,000 kg and declared at a customs value of $5,000,000 USD would attract a US duty of $250,000. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem, as published in the USITC Harmonized Tariff Schedule. The calculation is: 5.0% × $5,000,000 = $250,000. This rate applies if no preferential trade agreement is applicable.
Which trade agreements reduce duties for HS 840610?
Several free trade agreements may reduce the applicable duty rate for HS 840610, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, qualifying turbines originating from Canada or Mexico can enter the United States duty-free. Documentation required to claim this preference typically includes a valid Certificate of Origin. Other agreements might offer reduced rates for specific countries, but USMCA is a prominent example for North American trade, with a preferential rate of Free.

FAQ
What are the typical import duty rates for HS code 840610 (Turbines for marine propulsion)?
The Most Favored Nation (MFN) duty rate for HS code 840610 can vary. For example, under the US Harmonized Tariff Schedule (HTS), the general rate is 2.70% ad valorem. However, preferential rates are available for goods imported from countries with which the US has trade agreements. For instance, imports from Australia (AU), Canada (CA), Mexico (MX), and South Korea (KR) may have duty-free entry or reduced rates under agreements like the USMCA or KORUS FTA. Always consult the latest HTS or relevant trade agreement for the most current and specific rates applicable to your country of origin.
What specific criteria define a turbine for marine propulsion under HS code 840610?
HS code 840610 specifically covers 'Turbines for marine propulsion.' This classification applies to turbines designed and intended for use in propelling marine vessels. This typically includes steam turbines, gas turbines, and other types of prime movers that generate power to drive a ship's propeller or other propulsion systems. Exclusions may include turbines designed for other applications, such as power generation on land or for aircraft. The key is the intended use for marine propulsion.
How is the import duty for HS code 840610 calculated, and can you provide an example?
The duty for HS code 840610 is typically calculated on an ad valorem basis, meaning a percentage of the declared value of the goods. For instance, if the MFN duty rate is 2.70% and you import a marine propulsion turbine valued at $500,000 USD, the duty would be calculated as follows: $500,000 (Value) × 0.0270 (Duty Rate) = $13,500 USD. This amount would be payable to customs authorities. If the turbine is subject to a specific duty (e.g., per unit), the calculation would be rate per unit × number of units. Always verify the specific duty basis (ad valorem, specific, or compound) from the official tariff schedule.
What documentation is typically required when importing turbines classified under HS code 840610?
When importing turbines for marine propulsion (HS 840610), standard import documentation is required, which may include a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill; and a certificate of origin to claim preferential duty rates if applicable. Depending on the importing country and the specific type of turbine, additional documentation might be necessary, such as technical specifications, manufacturer's declarations, or import permits. It is crucial to consult the customs authority of the importing country for a comprehensive list of required documents.
Which trade agreements commonly offer preferential duty rates for HS code 840610?
Several trade agreements can provide preferential duty rates for HS code 840610. For imports into the United States, the USMCA (United States-Mexico-Canada Agreement) may offer reduced or zero duties for turbines originating from Canada or Mexico. Other agreements, such as bilateral FTAs with countries like South Korea (KORUS FTA) or Australia, can also lead to preferential treatment. For imports into the EU, the EU's Common Customs Tariff (TARIC) lists preferential rates for goods from countries with which the EU has Free Trade Agreements (FTAs). Importers should always check the specific provisions of the relevant trade agreement and the origin of the goods to determine eligibility for preferential treatment.
