HS 848310 Transmission shafts (including cam shafts and crank shafts) and cranks
Quick Answer: Transmission shafts, including cam shafts and crank shafts, and cranks imported under HS 848310 enter the UK at 4.00%, the EU at 4.00%, and the US at 2.5% under the Most Favored Nation (MFN) rate. This classification covers mechanical components designed to transmit rotational motion and power, essential for various machinery and vehicle applications. Importers should note the significant variation in US duty rates, with some origins receiving duty-free treatment, as detailed in USITC tariff data. According to CustomTariffs, understanding these jurisdictional differences is crucial for accurate customs declarations and cost management.

How to Classify This HS Code?
What products does HS 848310 cover?
This subheading covers transmission shafts, including cam shafts and crank shafts, and cranks, as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. These are mechanical components designed to transmit power from a source, such as an engine, to a driven component. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this category includes shafts with integral cranks or those designed to be fitted with cranks, essential for converting rotary motion to reciprocating motion or vice versa, or for transmitting rotary motion.
What falls outside HS 848310?
The following products are excluded from HS 848310: complete engines or gearboxes (which are classified under their respective headings, e.g., 8407 for spark-ignition internal combustion piston engines), flexible shafts (classified under 848390), and shafts that are primarily structural components rather than power transmission elements. For instance, a simple metal rod used for support would not be classified here, nor would a drive shaft that is part of a larger assembly if that assembly has a more specific classification under Chapter 84.
What are common classification mistakes for HS 848310?
A common error is misclassifying specialized shafts that, while transmitting power, have a primary function that dictates a different heading. For example, a propeller shaft for a ship might be classified under heading 8906 if it's considered part of the vessel's propulsion system. Additionally, confusion can arise with shafts that are integral to a machine tool; General Rule of Interpretation (GRI) 1 states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes, meaning the specific function within a machine can override a general classification.
How should importers classify products under HS 848310?
The correct procedure for classifying products under HS 848310 involves a thorough examination of the product's design, function, and material composition. Importers and customs brokers should consult the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and review the Explanatory Notes from the WCO. Key considerations include whether the item is a transmission shaft, cam shaft, crank shaft, or crank, and its primary purpose in power transmission, ensuring it aligns with the descriptive text of heading 8483 and subheading 848310.
How is the duty calculated for products under HS 848310?
A crankshaft for a heavy-duty diesel engine, weighing 50 kilograms and declared at a customs value of $1,000 USD, would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) rate of 3.5% ad valorem, applied to the declared value: 3.5% × $1,000 = $35.00. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 848310.10.00.
Which trade agreements reduce duties for HS 848310?
Several free trade agreements may reduce the applicable duty rate for HS 848310, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for qualifying goods originating from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also offers preferential rates, potentially Free, for originating goods from member countries like Japan. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a specific origin declaration for CPTPP, depending on the jurisdiction's requirements.

FAQ
What are the typical import duty rates for HS code 848310 (Transmission shafts and cranks)?
The Most Favored Nation (MFN) duty rate for HS code 848310 is typically 4.00% ad valorem in the United States. However, preferential duty rates can significantly reduce or eliminate this. For example, under the USMCA (United States-Mexico-Canada Agreement), originating goods may receive a Free rate. It is crucial to consult the latest Harmonized Tariff Schedule of the United States (HTSUS) for the most current and specific rates applicable to your country of origin. For other jurisdictions, consult the EU TARIC or UK Trade Tariff.
How is the duty for HS code 848310 calculated? Can you provide an example?
The duty for HS code 848310 is generally calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if a shipment of transmission shafts valued at $10,000 USD is imported into the U.S. with an MFN duty rate of 4.00%, the calculated duty would be: $10,000 (Value) × 0.04 (4.00% Duty Rate) = $400.00. Always ensure your customs value is accurately declared, including any applicable additions like freight and insurance, as per customs regulations.
What specific criteria determine if a part falls under HS code 848310?
HS code 848310 covers 'Transmission shafts (including cam shafts and crank shafts) and cranks'. The key classification criteria are that the item must be designed for transmitting mechanical power. This includes shafts used to transfer rotational motion, such as drive shafts, propeller shafts, and crankshafts used in engines. Cranks are also included if they are part of a mechanism for converting reciprocating motion to rotary motion or vice versa. Parts that do not serve this primary function of power transmission would likely be classified elsewhere.
What documentation is typically required for importing goods classified under HS code 848310?
Standard import documentation for HS code 848310 includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be required to claim preferential duty rates under trade agreements. Importers should also be prepared to provide technical specifications or product literature if customs authorities request further information to verify the classification and ensure compliance with any specific import regulations or standards.
Which common trade agreements offer preferential duty rates for HS code 848310?
Several trade agreements can provide preferential duty rates for HS code 848310. For imports into the United States, the USMCA (United States-Mexico-Canada Agreement) often grants a Free (0%) duty rate for originating goods. Other agreements, such as those with Australia (AU), South Korea (KR), or Singapore (SG), may also offer reduced or Free duty rates, as indicated by the 'Free (A,AU,B,BH,C,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)' notation in some tariff schedules. Importers must verify the 'Rules of Origin' for each agreement to ensure their goods qualify for preferential treatment.
