How to Classify This HS Code?
What products does HS 810320 cover?
This subheading covers unwrought tantalum, which includes tantalum in its primary, unrefined state, as well as bars and rods that have been produced simply by sintering. Powders of tantalum are also specifically included. According to the World Customs Organization (WCO) Harmonized System Nomenclature, unwrought tantalum is defined as metal in primary forms, including powders, granules, and sponge. The US International Trade Commission (USITC) Harmonized Tariff Schedule (HTS) further clarifies that this category encompasses tantalum that has not undergone further processing beyond basic metallurgical operations like sintering.
What falls outside HS 810320?
The following products are excluded from HS 810320: finished tantalum articles, alloys of tantalum, and tantalum that has undergone significant further processing beyond simple sintering. For instance, tantalum wire, plates, sheets, or foil, even if produced from sintered material, would typically be classified under a different subheading within heading 8103 or a more specific heading if they constitute finished goods. Tantalum compounds, such as tantalum pentoxide, are also classified elsewhere, generally under Chapter 28.
What are common classification mistakes for HS 810320?
A common error is misclassifying tantalum alloys as pure unwrought tantalum under HS 810320. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the heading and any relative section or chapter notes. If a product is an alloy, it should be classified under the heading for alloys, provided it is not specifically excluded. Importers may also incorrectly classify semi-finished products like rolled tantalum sheets as unwrought material, overlooking the requirement for simple sintering only.
How should importers classify products under HS 810320?
The correct procedure for classifying products under HS 810320 involves a thorough examination of the product's form and composition. Importers and customs brokers must verify if the tantalum is in its unwrought state, including bars and rods obtained solely by sintering, or in powder form. Consulting the official tariff schedule of the importing country, such as the USITC HTS or the EU TARIC, and referencing the WCO Explanatory Notes is crucial to confirm that the product meets the specific criteria for this subheading and is not a finished article or an alloy.
How is the duty calculated for products under HS 810320?
A shipment of 100 kilograms of unwrought tantalum powder, declared at a customs value of $50,000 USD, would attract a US duty of $2,500. This is calculated using the Most Favored Nation (MFN) rate of 5.0% ad valorem, applied to the declared value ($50,000 USD × 0.05 = $2,500). This calculation is based on the MFN duty rate published in the USITC Harmonized Tariff Schedule for subheading 8103.20.0000.
Which trade agreements reduce duties for HS 810320?
Several free trade agreements may reduce the applicable duty rate for HS 810320, including the United States-Mexico-Canada Agreement (USMCA). Under USMCA, originating tantalum from Canada or Mexico can enter the United States duty-free. To claim this preferential rate, a valid origin declaration or certificate of origin is typically required, depending on the specific requirements of US Customs and Border Protection. Other agreements might exist depending on the importing country, but USMCA is a prominent example for North American trade.

FAQ
What are the import duty rates for HS code 810320 (Unwrought tantalum)?
The Most Favored Nation (MFN) duty rate for unwrought tantalum, including bars and rods obtained simply by sintering, and powders, under HS code 810320, is 2.5% ad valorem. However, preferential duty rates are available under various trade agreements. For example, under the US-Australia Free Trade Agreement (AU), the duty rate is Free. Importers should consult the specific tariff schedule of the importing country and any applicable trade agreements to determine the precise duty rate. For the US, the Harmonized Tariff Schedule (HTS) is available on the US International Trade Commission (USITC) website.
How is the import duty for HS 810320 calculated?
The import duty for HS code 810320 is typically calculated on an ad valorem basis, meaning it is a percentage of the declared customs value of the imported goods. For instance, if unwrought tantalum powder valued at $10,000 is imported into the United States and subject to the MFN duty rate of 2.5%, the calculated duty would be $10,000 (value) × 0.025 (duty rate) = $250. Importers must ensure accurate valuation of the goods as per customs regulations.
What documentation is typically required for importing unwrought tantalum (HS 810320)?
Importing unwrought tantalum under HS code 810320 generally requires standard import documentation, including a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country and the specific nature of the tantalum, additional documentation may be necessary. This could include a certificate of origin to claim preferential duty rates, and potentially specific licenses or permits related to strategic materials or dual-use goods, especially if the tantalum has applications in sensitive industries. It is advisable to consult the customs authority of the destination country for a comprehensive list of requirements.
Which trade agreements offer preferential duty rates for HS 810320?
Several trade agreements provide preferential duty rates for unwrought tantalum (HS 810320). For example, under the US Free Trade Agreements with countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), South Korea (KR), Morocco (MA), Oman (OM), Peru (PE), and Singapore (SG), this product may be eligible for Free entry, provided that the goods meet the rules of origin stipulated in each agreement. Importers must ensure they have the correct documentation, such as a certificate of origin, to substantiate their claim for preferential treatment. The specific details for each agreement can be found in the respective tariff schedules of the importing countries.
What are the classification criteria for unwrought tantalum under HS 810320?
HS code 810320 covers 'Unwrought tantalum, including bars and rods obtained simply by sintering; powders'. 'Unwrought' generally refers to metal that has not been processed beyond its initial smelting or melting stage, or basic forming processes like sintering. This includes forms such as ingots, blocks, lumps, and powders. Bars and rods obtained simply by sintering are also included. If the tantalum has undergone further manufacturing processes, such as rolling, drawing, or extrusion into more finished shapes, it would likely be classified under a different HS code. The Explanatory Notes to the Harmonized System provide further guidance on the interpretation of 'unwrought'.
