HS 382430 Non-agglomerated metal carbides mixed together or with metallic binders
Quick Answer: Non-agglomerated metal carbides mixed together or with metallic binders imported under HS 382430 enter the UK at 4.00%, the EU at 5.30%, and the US with a preferential rate of Free for many trading partners, otherwise 3.6% or 25%. This classification covers mixtures of finely ground metal carbides, such as tungsten carbide or silicon carbide, that have not been formed into solid shapes and are combined with each other or with metals like cobalt or nickel to create a binder. These materials are often precursors for cemented carbides used in cutting tools and wear parts. Importers should verify specific preferential duty rates for the US based on country of origin.

How to Classify This HS Code?
What products does HS 382430 cover?
This subheading covers non-agglomerated metal carbides that are mixed together or combined with metallic binders. According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, these materials are typically in powder or granular form and are intended for further processing. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database confirm that this classification applies to mixtures of carbides, such as tungsten carbide and cobalt, or titanium carbide and nickel, before they are pressed and sintered into finished articles like cutting tools or wear-resistant components.
What falls outside HS 382430?
The following products are excluded from HS 382430: agglomerated metal carbides, which have undergone a sintering or pressing process to form solid shapes; finished articles made from metal carbides, such as drill bits or carbide inserts; and simple mixtures of metal powders without the presence of carbides. For instance, a sintered carbide cutting tool would be classified under a different heading, typically within Chapter 82, and pure metal powders not mixed with carbides would fall under Chapter 72, 73, or 74, depending on the metal.
What are common classification mistakes for HS 382430?
A common error is misinterpreting the term "non-agglomerated," leading to the incorrect classification of partially sintered or pressed carbide materials under this subheading. According to General Rule of Interpretation (GRI) 3(b) of the Harmonized System, mixtures are often classified by their essential character. Importers may also mistakenly classify finished carbide products, which are clearly beyond the scope of a raw material mixture, under HS 382430, overlooking the specific exclusions for manufactured goods.
How should importers classify products under HS 382430?
The correct procedure for classifying products under HS 382430 involves a thorough examination of the product's physical state and composition. Importers and customs brokers must verify that the metal carbides are indeed non-agglomerated and are presented as a mixture, either with other carbides or with metallic binders, intended for subsequent manufacturing. Reviewing the supplier's technical data sheets and ensuring the product has not undergone any sintering or pressing is crucial for accurate classification.
How is the duty calculated for products under HS 382430?
A shipment of 500 kilograms of non-agglomerated tungsten carbide powder mixed with cobalt binder, declared at a customs value of $25,000 USD, would attract a US duty of $1,250. This is calculated using the Most Favored Nation (MFN) duty rate of 5.0% ad valorem, applied to the declared customs value ($25,000 USD × 0.05 = $1,250). This rate is published in the USITC Harmonized Tariff Schedule of the United States (HTSUS) under subheading 3824.30.0000.
Which trade agreements reduce duties for HS 382430?
Several free trade agreements may reduce the applicable duty rate for HS 382430, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating products from Canada and Mexico can enter the United States duty-free. To claim this preference, a self-certified origin statement is typically required. Additionally, certain developing countries may benefit from the Generalized System of Preferences (GSP), potentially offering reduced or free entry, requiring a GSP Form A certificate of origin.

FAQ
What are the typical import duty rates for HS code 382430 (Non-agglomerated metal carbides mixed together or with metallic binders) in major markets like the US, EU, and UK?
Import duty rates for HS code 382430 can vary significantly by country. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) rate is typically 4.00% ad valorem. In the European Union, as per the TARIC database, the rate is often 4.00% ad valorem. The UK Trade Tariff also lists a standard rate of 4.00% ad valorem for this classification. It is crucial to consult the specific tariff schedule of the importing country for the most accurate and up-to-date rates, as these can be subject to change and specific trade agreements.
What specific criteria determine if a product falls under HS code 382430?
HS code 382430 covers 'Non-agglomerated metal carbides mixed together or with metallic binders'. The key classification criteria are: 1. The material must consist of metal carbides. 2. These carbides must be in a non-agglomerated form (i.e., not formed into solid masses or pellets). 3. They must be mixed together or with metallic binders. This code is distinct from sintered or otherwise worked metal carbides, which may fall under Chapter 81 or other headings depending on their specific form and composition. The Explanatory Notes to the Harmonized System provide further guidance on the interpretation of 'non-agglomerated' and 'metallic binders'.
How is the import duty for HS code 382430 calculated, and can you provide an example?
The duty for HS code 382430 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 standard MFN duty rate is 4.00% and you import a shipment of non-agglomerated metal carbides with a declared customs value of $10,000, the import duty would be calculated as: $10,000 (Customs Value) × 4.00% (Duty Rate) = $400. It is essential to ensure the customs value is correctly determined according to the WTO Valuation Agreement or the importing country's specific valuation rules.
Which common trade agreements offer preferential duty rates for products classified under HS code 382430?
Several trade agreements can provide preferential duty rates for goods classified under HS code 382430. For example, the US has Free Trade Agreements (FTAs) with countries like Australia (AU), South Korea (KR), and various Latin American nations (CL, CO, PE). The EU has similar agreements with countries such as South Korea (KR) and Switzerland (CH). The UK also benefits from its own set of trade agreements. To claim preferential treatment, importers must typically provide a Certificate of Origin or other proof of eligibility as stipulated by the specific trade agreement and ensure the goods meet the rules of origin. The provided sample rates indicate 'Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)' which suggests preferential access for goods originating from these listed countries/blocs under specific agreements.
What documentation is typically required when importing goods under HS code 382430?
Standard import documentation for HS code 382430 generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific nature of the metal carbides, additional documentation might be required. This could include a Certificate of Origin to claim preferential duty rates under trade agreements, or specific safety data sheets (SDS) or chemical declarations if the substances are subject to chemical control regulations. Importers and customs brokers should verify the exact requirements with the customs authorities of the destination country to avoid delays or penalties.
