Quick Answer: Parts for toothed wheels, chain sprockets, and other transmission elements presented separately enter the UK duty-free, the EU at rates up to 5.70% ad valorem, and the US with rates ranging from Free to 45% ad valorem, depending on the country of origin. This classification covers individual components like gears, sprockets, and couplings that are not part of a complete assembly.

How to Classify This HS Code?

```html

What products does HS 848390 cover?

This subheading covers toothed wheels, chain sprockets, and other transmission elements when presented separately, as well as parts thereof. According to the World Customs Organization's Harmonized System Nomenclature, this category encompasses components designed to transmit mechanical power, such as gears, sprockets for chains, and pulleys, provided they are not integrated into a larger assembly. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these items are classified here when imported as individual parts or components for transmission systems.

What falls outside HS 848390?

The following products are excluded from HS 848390: complete transmission assemblies, such as gearboxes or complete drive shafts, which are classified under the relevant headings for the complete machinery or equipment. Also excluded are finished articles incorporating these transmission elements, such as bicycles with their integrated sprockets and chains, or motor vehicles. Parts of general use, as defined in Section XV Note 2, such as screws or bolts, even if used in transmission systems, are classified separately under their respective headings.

What are common classification mistakes for HS 848390?

A common error is the misclassification of complete transmission assemblies as separate parts under HS 848390. This often occurs when importers mistakenly classify a partially assembled unit or a kit containing multiple transmission components as individual parts. According to General Rule of Interpretation (GRI) 2(a), an incomplete or unfinished article is classified as if it were the complete article if it has the essential character of the complete article. Therefore, a nearly complete gearbox would not be classified here.

How should importers classify products under HS 848390?

The correct procedure for classifying products under HS 848390 involves a detailed examination of the product's function and presentation. Importers and customs brokers must determine if the item is a toothed wheel, chain sprocket, or other transmission element presented separately, or a part thereof. Consulting the official tariff schedules of the importing country, such as the USITC HTS or the UK Trade Tariff, and referencing the WCO Explanatory Notes is crucial for accurate classification and to avoid potential penalties.

How is the duty calculated for products under HS 848390?

A shipment of 100 steel chain sprockets, each weighing 0.5 kg, with a total declared customs value of $500 USD, would attract a US duty of $35.00. This is calculated using the Most Favored Nation (MFN) rate of 7.0% ad valorem, applied to the declared value. Therefore, the duty is 7.0% × $500 USD = $35.00. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8483.90.0000.

Which trade agreements reduce duties for HS 848390?

Several free trade agreements may reduce the applicable duty rate for HS 848390, including the United States-Mexico-Canada Agreement (USMCA), which can lead to a duty rate of Free for qualifying goods originating from Canada or Mexico. Additionally, the Generalized System of Preferences (GSP) may offer reduced or Free duty rates for eligible goods from certain developing countries. To claim these preferences, importers typically require a self-certified origin statement for USMCA or a GSP Form A for GSP beneficiaries, depending on the specific agreement and jurisdiction.

FAQ

What are the typical import duty rates for HS code 848390 (Toothed wheels, chain sprockets and other transmission elements presented separately; parts)?

The Most Favored Nation (MFN) duty rate for HS code 848390 in the United States is 2.70% ad valorem. However, preferential duty rates are available for goods originating from countries with trade agreements with the US. For example, goods from Australia (AU) may enter duty-free under the Free Trade Agreement (FTA) provisions (indicated by 'Free (A*,AU,B,BH,C,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)'). Always verify the specific origin and applicable trade agreement to determine the correct duty rate. Refer to the US Harmonized Tariff Schedule (HTS) for the most current rates.

How is the import duty for HS 848390 calculated, and can you provide an example?

The import duty for HS code 848390 is typically calculated on an ad valorem basis, meaning it's a percentage of the declared customs value of the goods. For instance, if the MFN duty rate is 2.70% and you import toothed wheels valued at $10,000 USD, the duty would be calculated as: $10,000 (Value) × 0.0270 (Duty Rate) = $270 USD. It is crucial to ensure the customs value is accurately declared according to CBP regulations.

What are the key classification criteria for items falling under HS code 848390?

HS code 848390 covers toothed wheels, chain sprockets, gears, belt pulleys, and other transmission elements that are presented separately. This also includes parts specifically designed for such transmission elements. The key criterion is that these items are designed to transmit mechanical power, either through meshing teeth (gears, sprockets) or by engaging with belts or chains. They must be presented as individual components or sets of components, not as part of a larger assembled machine.

What documentation is typically required when importing goods classified under HS 848390?

When importing goods under HS code 848390, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. Crucially, you will need a declaration of origin to claim preferential duty rates under any applicable Free Trade Agreements (FTAs). Importers should also be prepared to provide technical specifications or catalog information if requested by Customs and Border Protection (CBP) to verify the classification and intended use of the transmission elements.

Which major trade agreements commonly offer preferential duty rates for HS code 848390 into the United States?

Several trade agreements can provide preferential duty rates for goods classified under HS code 848390 into the United States. These include agreements with countries like Australia (AU), Canada (CA) and Mexico (MX) under the United States-Mexico-Canada Agreement (USMCA), Chile (CL), South Korea (KR), and others listed under the 'Free (A*,AU,B,BH,C,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)' column in the HTS. To benefit from these rates, importers must ensure the goods meet the rules of origin specified in the respective trade agreement and possess the necessary proof of origin documentation.
