How to Classify This HS Code?
What products does HS 848340 cover?
This subheading covers gears and gearing, excluding toothed wheels, chain sprockets, and other transmission elements presented separately. It specifically includes ball or roller screws, gear boxes, and other speed changers, such as torque converters, as defined by the World Customs Organization's Harmonized System Nomenclature. The USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this category encompasses complete transmission units designed to alter speed or torque, including planetary gearboxes and hydrostatic transmissions.
What falls outside HS 848340?
The following products are excluded from HS 848340: individual toothed wheels, chain sprockets, and other transmission elements when presented separately, as these are typically classified under HS 8483.90. Additionally, complete machines or assemblies of which the gear box or speed changer is only a component part, such as an engine with an integrated gearbox, are classified according to their principal function. For instance, a complete vehicle transmission system is not classified here but within the vehicle's heading.
What are common classification mistakes for HS 848340?
A common error is misclassifying individual transmission components, such as gears or sprockets, under this subheading when they should be classified as separate elements under HS 8483.90. Another mistake involves classifying complete machinery where a gearbox is a sub-component. According to General Rule of Interpretation (GRI) 3(b), goods consisting of different materials or components which cannot be readily separated are classified by the material or component giving them their essential character, which often leads to classification outside of 848340 for complex assemblies.
How should importers classify products under HS 848340?
The correct procedure for classifying products under HS 848340 involves a detailed examination of the product's nature and function. Importers and customs brokers must determine if the item is a complete gear box, speed changer, torque converter, or a ball/roller screw. Reference to the official WCO Explanatory Notes, the USITC HTS, or the EU TARIC database is crucial. If the product is a component part of a larger machine, its classification will likely differ, requiring analysis of the entire assembly's essential character.
How is the duty calculated for products under HS 848340?
A planetary gearbox for industrial machinery, weighing 150 kg and declared at a customs value of $5,000 USD, would attract a US duty of $175.00. This is calculated using the MFN rate of 3.5% ad valorem published in the USITC Harmonized Tariff Schedule (HTS 8483.40.0000), resulting in $5,000 USD × 0.035 = $175.00. For the EU, a similar item might have a duty rate of 2.7% ad valorem, leading to a duty of €135.00 based on an equivalent Euro value.
Which trade agreements reduce duties for HS 848340?
Several free trade agreements may reduce the applicable duty rate for HS 848340, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for eligible goods originating from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, often Free, for qualifying products from member countries like Japan and Singapore. To claim these preferences, a valid USMCA Certificate of Origin or a CPTPP Certificate of Origin is typically required, depending on the origin country and the specific agreement's documentation requirements.

FAQ
What are the typical import duty rates for HS code 848340 (Gears and gearing, etc.)?
Import duty rates for HS code 848340 can vary significantly depending on the importing country and any applicable trade agreements. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is generally 3.70% ad valorem. However, preferential rates may apply. For instance, goods originating from countries with a Free Trade Agreement (FTA) with the US, such as Mexico under USMCA, might be eligible for duty-free entry (0.00%). Always consult the specific tariff schedule of the importing country and verify the country of origin to determine the applicable duty rate.
How is the import duty for HS 848340 calculated, and can you provide an example?
The duty for HS code 848340 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 gearboxes (classified under 848340) has a customs value of $10,000 and the applicable MFN duty rate is 3.70%, the import duty would be calculated as: $10,000 (Customs Value) × 0.0370 (Duty Rate) = $370.00. In some cases, specific components or types of gearing might have specific unit duties or a combination of ad valorem and specific duties, so it's crucial to check the detailed tariff notes.
What are the key classification criteria for goods falling under HS code 848340?
HS code 848340 covers 'Gears and gearing, other than toothed wheels, chain sprockets and other transmission elements presented separately; ball or roller screws; gear boxes and other speed changers, including torque converters'. Key classification criteria include: 1. Functionality: The item must be a transmission element. 2. Form: It can be a complete gearbox, speed changer, torque converter, or a ball/roller screw. 3. Exclusions: Toothed wheels, chain sprockets, and other transmission elements are excluded if presented separately; they would likely be classified under HS 8483.90. The core distinction is whether the item is a complete unit for changing speed or torque, or a component like a screw designed for linear motion conversion.
Are there specific documentation requirements for importing goods under HS code 848340?
While specific documentation can vary by importing country and the nature of the goods, common requirements for HS code 848340 include: 1. Commercial Invoice: Detailing the description, quantity, unit price, and total value of the goods. 2. Packing List: Outlining the contents of each package. 3. Bill of Lading/Air Waybill: As the contract of carriage. 4. Country of Origin Certificate: Essential for claiming preferential duty rates under trade agreements. 5. Technical Specifications/Catalogues: May be required to verify the classification and ensure compliance with any specific regulations or standards for machinery components. Importers should always consult the customs authority of the destination country for a comprehensive list.
How do trade agreements, like USMCA or EU trade deals, affect duties for HS 848340?
Trade agreements significantly impact duty rates for HS code 848340 by potentially reducing or eliminating tariffs for goods that meet specific rules of origin. For example, under the United States-Mexico-Canada Agreement (USMCA), qualifying goods originating from Canada, Mexico, or the United States may be eligible for duty-free entry into any of these member countries, effectively lowering the duty from the standard MFN rate (e.g., 3.70% in the US) to 0.00%. Similarly, the European Union has numerous trade agreements that can offer preferential treatment for goods classified under 848340. To benefit, importers must possess a valid proof of origin document (e.g., Certificate of Origin) and ensure the goods meet the specific rules of origin outlined in the respective trade agreement.
