How to Classify This HS Code?
What products does HS 810110 cover?
This subheading covers powders of tungsten, including waste and scrap. According to the World Customs Organization (WCO) Harmonized System Nomenclature, this classification is for tungsten in powdered form, irrespective of its purity or particle size, as long as it is presented as a powder. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this category is specifically for the finely divided form of tungsten, distinct from solid forms or alloys not yet reduced to powder.
What falls outside HS 810110?
The following products are excluded from HS 810110: solid forms of tungsten, tungsten alloys not in powder form, tungsten ores and concentrates, and manufactured articles of tungsten such as filaments, electrodes, or tools, which are classified under their respective headings. For instance, tungsten carbide powders used in cemented carbides are typically classified under HS 2849.90, and finished tungsten wire for lighting would fall under HS 8539.90. The key distinction is the physical form; if it is not a powder, it does not belong here.
What are common classification mistakes for HS 810110?
A common error is misclassifying tungsten compounds or alloys that are not pure tungsten powder. For example, tungsten carbide, which is a compound, is not covered by this heading. Another mistake involves confusing tungsten powder with tungsten scrap or waste that has not been sufficiently processed into a powder form. Adherence to General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative Section or Chapter Notes, is crucial to avoid these errors.
How should importers classify products under HS 810110?
The correct procedure for classifying products under HS 810110 involves a thorough examination of the product's physical form and composition. Importers and customs brokers must verify that the material is indeed tungsten in a powdered state. Consulting the official tariff schedule of the importing country, such as the USITC HTS or the UK Trade Tariff, and cross-referencing with WCO Explanatory Notes is essential. If the product is a waste or scrap of tungsten that has been processed into a powder, it fits this subheading.
How is the duty calculated for products under HS 810110?
A 100 kg shipment of pure tungsten powder, declared at a customs value of $5,000 USD, would attract a US duty of $350.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.5% ad valorem, applied to the declared value. The calculation is $5,000 USD × 0.035 = $175.00. *Correction: The initial calculation was incorrect. The correct calculation for a 3.5% ad valorem duty on a $5,000 USD value is $5,000 USD × 0.035 = $175.00. This is calculated using the MFN rate published in the USITC Harmonized Tariff Schedule.*
Which trade agreements reduce duties for HS 810110?
Several free trade agreements may reduce the applicable duty rate for HS 810110, including the United States-Mexico-Canada Agreement (USMCA) and the Generalized System of Preferences (GSP) for certain developing countries. Under USMCA, originating tungsten powder from Canada or Mexico may be eligible for a duty rate of Free. To claim this preference, a valid USMCA certification of origin is required. For GSP beneficiaries, a Form A (Certificate of Origin) is typically needed to claim preferential duty rates, which can also be Free for eligible countries like Vietnam.

FAQ
What are the primary classification criteria for HS code 810110 (Powders)?
HS code 810110 specifically covers 'Powders' of tungsten. The key classification criterion is that the material must be in a powdered form, meaning it consists of fine particles. This distinguishes it from other forms of tungsten, such as unwrought tungsten, bars, rods, or finished articles, which would fall under different HS codes within Chapter 81. The particle size is not explicitly defined in the tariff but generally refers to a state suitable for metallurgical processing like sintering or pressing.
What are the typical import duty rates for HS code 810110 (Powders) into the United States?
The Most Favored Nation (MFN) duty rate for HS code 810110 (Powders of tungsten) into the United States is 5.00% ad valorem. This rate applies to imports from countries that do not have specific preferential trade agreements with the U.S. For example, if a shipment of tungsten powder valued at $10,000 is imported, the duty would be $10,000 \times 5.00% = $500. Importers should always verify current rates on the U.S. International Trade Commission (USITC) website, as these can be subject to change or specific trade actions.
Are there any preferential duty rates available for HS code 810110 (Powders) under trade agreements?
Yes, preferential duty rates may be available for HS code 810110 depending on the country of origin and applicable trade agreements. For instance, under certain agreements, specific countries might benefit from reduced or duty-free entry. For example, the U.S. has agreements that could offer 'Free' (0.00%) duty rates for products originating from countries like Australia (AU), Chile (CL), or South Korea (KR), among others listed in the 'Free (A+,AU,BH,CL,CO,D,E,IL,JO,KR,MA, OM,P,PA,PE,S,SG)' designation. To claim these preferential rates, importers must provide valid proof of origin, such as a certificate of origin, and ensure the goods meet the rules of origin stipulated in the respective trade agreement. Always consult the latest tariff schedule and the specific trade agreement text for definitive eligibility.
What documentation is typically required for importing tungsten powders (HS 810110)?
Standard documentation for importing tungsten powders under HS code 810110 includes a commercial invoice detailing the value, quantity, and description of the goods; a packing list; a bill of lading or air waybill for transportation; and a customs entry summary. Crucially, for claiming preferential duty rates, a valid Certificate of Origin or other approved proof of origin demonstrating that the goods qualify under a specific trade agreement is mandatory. Depending on the importing country's regulations and the specific nature of the tungsten powder, additional certifications related to material composition or compliance with environmental or safety standards might be requested by customs authorities. It is advisable for importers and customs brokers to consult the importing country's customs agency for a comprehensive list of required documents.
How is the import duty for tungsten powders (HS 810110) calculated if a specific trade agreement does not apply?
If no preferential trade agreement applies, the import duty for tungsten powders (HS 810110) is typically calculated based on the ad valorem rate, which is a percentage of the customs value of the imported goods. For example, if the standard MFN duty rate is 5.00% and a shipment of tungsten powder has a declared customs value of $25,000, the import duty would be calculated as: $25,000 (Customs Value) \times 5.00% (Duty Rate) = $1,250. The customs value is generally based on the transaction value, which is the price actually paid or payable for the goods. Importers must ensure accurate valuation and classification to avoid penalties.
