HS 850300 Non-magnetic retaining rings
Quick Answer: Non-magnetic retaining rings imported under HS 850300 enter the UK at 2.00%, the EU at 2.70%, and the US at 6.5% (MFN). This classification covers mechanical components designed to secure a shaft or bore, preventing axial movement. These are typically split rings or similar fasteners, distinct from magnetic types. Importers should note that the US offers duty-free entry for goods from certain preferential trade partners, as detailed in USITC tariff data. Exporters and customs brokers should verify specific preferential rates applicable to their destination market. CustomTariffs aggregates this information for compliance.

How to Classify This HS Code?
What products does HS 850300 cover?
This subheading covers non-magnetic retaining rings, which are mechanical components designed to secure a component or shaft in place by fitting into a groove. According to the World Customs Organization's Harmonized System Nomenclature, this category falls under Heading 8503, specifically for parts of electric motors, generators, and rotary converters. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that these rings, when not magnetic, are classified here if they are primarily intended for use with machinery within Heading 8503.
What falls outside HS 850300?
The following products are excluded from HS 850300: magnetic retaining rings, which are classified under their respective magnetic material headings or specific machinery parts headings if their magnetic property is integral to their function. Also excluded are general-purpose fasteners like standard nuts, bolts, and washers (Chapter 73 or 83), and retaining rings designed for non-electrical machinery (e.g., automotive parts classified under Chapter 87). The key distinction is the intended use with electrical machinery as defined in Heading 8503.
What are common classification mistakes for HS 850300?
A common error is misclassifying retaining rings based solely on their material without considering their intended application. For instance, a retaining ring made of steel that is intended for an automotive engine would not be classified under 850300. General Interpretative Rule 1 (GIR 1) dictates that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes. Importers may also incorrectly classify magnetic retaining rings under this subheading, overlooking the "non-magnetic" exclusion.
How should importers classify products under HS 850300?
The correct procedure for classifying products under HS 850300 involves a thorough examination of the product's intended use and its physical characteristics. Importers and customs brokers must verify that the retaining ring is specifically designed for use with electrical machinery covered by Heading 8503 and that it is not magnetic. Consulting the WCO HS Explanatory Notes and the specific tariff schedule of the importing country (e.g., USITC HTS, UK Trade Tariff) is crucial for accurate determination.
How is the duty calculated for products under HS 850300?
A shipment of 10,000 E-clip retaining rings, each weighing 0.005 kg (totaling 50 kg), 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) duty rate of 3.5% ad valorem, applied to the declared value ($1,000 USD × 0.035 = $35.00). This calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 8503.00.90, which covers parts of electrical machinery.
Which trade agreements reduce duties for HS 850300?
Several free trade agreements may reduce the applicable duty rate for HS 850300, 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 EU-UK Trade and Cooperation Agreement also offers preferential rates, often Free, for goods originating from the EU or UK. To claim these preferences, importers typically require a self-certified origin statement for USMCA or an EUR.1 movement certificate for EU/UK trade, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 850300 (parts for electric motors, generators, etc.)?
The Most Favored Nation (MFN) duty rate for HS code 850300, which covers parts for electric motors, generators, and converters, varies by country. For example, the U.S. tariff rate is 2.70% ad valorem. The EU's TARIC system may have different rates depending on specific product characteristics and origin. The UK Trade Tariff also lists specific rates. It is crucial to consult the latest official tariff schedule for the importing country to determine the exact rate applicable to your shipment.
How is the import duty for HS code 850300 calculated? Can you provide an example?
The duty for HS code 850300 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 parts valued at $10,000 USD, the import duty would be $10,000 USD * 0.0270 = $270 USD. Always ensure your customs value is accurately declared, including all assessable costs like freight and insurance, as this forms the basis for duty calculation.
What are the classification criteria for HS code 850300?
HS code 850300 covers 'Parts suitable for use solely or principally with the machines of heading 8501 or 8502'. This includes parts for electric motors, generators (including sets), and converters. Classification hinges on whether the part is specifically designed or adapted for these machines and not more specifically classified elsewhere. Common examples include casings, stators, rotors, and brush holders for electric motors and generators. The WCO's Explanatory Notes provide detailed guidance on the scope of this heading.
Which trade agreements offer preferential duty rates for HS code 850300?
Several trade agreements can provide preferential duty rates for goods classified under HS 850300. For example, under the USMCA (United States-Mexico-Canada Agreement), goods may qualify for 0% duty if they meet the rules of origin. Other agreements, such as those with Australia (AU), South Korea (KR), or Singapore (SG), may also offer reduced or duty-free access, as indicated by the preferential rates listed (e.g., 'Free (A,AU,B,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)'). Importers must obtain a valid Certificate of Origin and ensure the goods meet the specific rules of origin for the relevant trade agreement to claim preferential treatment.
What documentation is typically required when importing goods under HS code 850300?
When importing parts for electric motors, generators, or converters under HS code 850300, standard import documentation is required. This includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the origin of the goods, a Certificate of Origin may be necessary to claim preferential duty rates under trade agreements. Additionally, specific product certifications or declarations related to electrical safety or compliance might be required by the importing country's regulations. Always verify the specific documentation requirements with the customs authority of the destination country.
