How to Classify This HS Code?
What products does HS 840681 cover?
This subheading covers "other turbines," specifically those not falling under the more specific categories of steam turbines or gas turbines within heading 8406. According to the World Customs Organization's Harmonized System Nomenclature, this includes turbines driven by fluids other than steam or gas, such as hydraulic turbines. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm this broad inclusion for turbines not explicitly classified elsewhere in 8406, provided they are prime movers converting fluid energy into mechanical power.
What falls outside HS 840681?
The following products are excluded from HS 840681: steam turbines (HS 840610), gas turbines other than turbo-jets or turbo-propellers (HS 840682), and turbo-jets or turbo-propellers (HS 840690). Additionally, pumps that operate on the same principles but are designed to move fluids rather than generate power, such as centrifugal pumps (HS 8413), are classified separately. Engines that combust fuel internally to produce mechanical power, like internal combustion piston engines (Chapter 84, heading 8407 or 8408), are also distinct.
What are common classification mistakes for HS 840681?
A common error is misclassifying hydraulic turbines or other fluid-driven prime movers as pumps or general machinery. This often stems from a misunderstanding of the core function; turbines are designed to extract energy from a fluid to produce rotational power, while pumps are designed to impart energy to a fluid. Adherence to General Interpretative Rule 1, which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes, is crucial to avoid these errors.
How should importers classify products under HS 840681?
The correct procedure for classifying products under HS 840681 involves a detailed examination of the product's design, function, and the energy source it utilizes. Importers and customs brokers must first consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and review the explanatory notes for heading 8406. If the turbine is not a steam or gas turbine and is designed to convert fluid energy into mechanical power, it likely falls under this subheading.
How is the duty calculated for products under HS 840681?
A Francis hydraulic turbine weighing 5,000 kg and declared at a customs value of $150,000 USD would attract a US duty of $10,500. This is calculated using the Most Favored Nation (MFN) rate of 7% ad valorem ($150,000 × 0.07 = $10,500). This calculation is based on the MFN rate published in the USITC Harmonized Tariff Schedule for HS code 840681, which applies to "Other turbines."
Which trade agreements reduce duties for HS 840681?
Several free trade agreements may reduce the applicable duty rate for HS 840681, 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. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for goods from member countries like Japan. To claim these preferences, a self-certified origin statement for USMCA or a specific origin declaration for CPTPP is typically required, depending on the importing country's regulations.

FAQ
What is the import duty for HS code 840681, "Other turbines"?
The Most Favored Nation (MFN) duty rate for HS code 840681 is typically 2.70% ad valorem. However, preferential rates are available under various trade agreements. For example, under the US-Australia Free Trade Agreement, the duty rate is Free (0.00%). Under the US-Japan Strategic and Economic Partnership, the duty rate is 3.35% ad valorem. It is crucial to consult the specific tariff schedule of the importing country and any applicable trade agreements to determine the exact duty rate. For instance, if importing goods valued at $10,000 USD with a 2.70% MFN duty, the duty amount would be $10,000 * 0.0270 = $270.00 USD.
What are the classification criteria for HS code 840681, "Other turbines"?
HS code 840681 covers turbines not specifically listed under other headings within Chapter 84, specifically those not covered by 8406.10 (Steam turbines and other vapor turbines) or 8406.82 (Gas turbines with a power not exceeding 5,000 kW). This typically includes turbines driven by fluids other than steam or gas, such as water turbines (hydroturbines) or wind turbines, provided they do not fall under more specific subheadings. The classification hinges on the type of motive fluid and the power output if applicable to specific subheadings.
What documentation is typically required for importing goods classified under HS code 840681?
When importing goods under HS code 840681, standard import documentation is required, which generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the origin and destination, a certificate of origin may be necessary to claim preferential duty rates. For turbines, especially those with significant power output or specific applications, manufacturers' specifications, technical drawings, and potentially safety or performance certifications might be requested by customs authorities to verify classification and compliance with national standards.
Which common trade agreements offer preferential duty rates for HS code 840681?
Several trade agreements provide preferential duty rates for HS code 840681. For example, agreements like the US-Australia Free Trade Agreement (AU) offer duty-free entry. Other agreements, such as those with countries like Canada (CUSMA/USMCA), Mexico (CUSMA/USMCA), and South Korea (KORUS FTA), may also offer reduced or zero duty rates, contingent on meeting the rules of origin specified within each agreement. Importers should verify the specific provisions of the relevant trade agreement for the exporting country to confirm eligibility and required documentation, such as a certificate of origin.
How is the duty calculated for HS code 840681 if the import value is $50,000 and the country of origin is eligible for a 0.00% duty rate?
If the import value for goods classified under HS code 840681 is $50,000 and the country of origin is eligible for a 0.00% duty rate (e.g., under certain free trade agreements), the duty calculation is as follows: Duty Amount = Import Value × Duty Rate. In this case, Duty Amount = $50,000 × 0.00 = $0.00. Therefore, no import duty would be payable on this shipment, provided all conditions for the preferential rate, including rules of origin, are met and properly documented.
