How to Classify This HS Code?
What products does HS 810391 cover?
This subheading covers "Other" unwrought aluminum and aluminum articles, as defined by the World Customs Organization's Harmonized System (WCO HS) nomenclature, that are not specifically classified under preceding subheadings within Heading 8103. This includes, but is not limited to, aluminum powders, flakes, and granules, as well as semi-finished products like bars, rods, and profiles of aluminum, provided they do not meet the specific criteria for other subheadings. For example, the USITC Harmonized Tariff Schedule (HTS) and the EU TARIC database would typically list specific forms of aluminum not covered elsewhere under this residual category.
What falls outside HS 810391?
The following products are excluded from HS 810391: unwrought aluminum (8103.20), aluminum waste and scrap (7602.00), and finished articles of aluminum such as doors, windows, and their frames (7609.00 onwards). Also excluded are aluminum foil (7607.11 and 7607.19), aluminum wire (7605.11 and 7605.19), and aluminum tubes, pipes, and fittings (7608.10 onwards). These items have their own distinct HS classifications based on their form and function, as detailed in the WCO HS Explanatory Notes and national tariff schedules.
What are common classification mistakes for HS 810391?
A common error is misclassifying semi-finished aluminum products that have undergone specific processing, such as extrusion or drawing, which may place them under Chapter 76 (Aluminum and articles of aluminum) rather than Heading 8103. For instance, aluminum bars intended for further fabrication into specific components might be incorrectly placed here. Adherence to General Rule of Interpretation (GRI) 1 and GRI 3 is crucial, especially when determining the essential character of a composite product or when faced with multiple potential headings.
How should importers classify products under HS 810391?
The correct procedure for classifying products under HS 810391 involves a thorough examination of the product's physical characteristics, its intended use, and the specific definitions provided in the WCO HS Nomenclature and relevant national tariff schedules, such as the USITC HTS or the EU TARIC. Importers and customs brokers must consult the Explanatory Notes to the Harmonized System and any specific rulings or decisions issued by customs authorities to ensure accurate classification, paying close attention to any specific processing or form that might exclude the item from this residual category.
How is the duty calculated for products under HS 810391?
A shipment of 1,000 kilograms of aluminum powder, declared at a customs value of $5,000 USD, would attract a US duty of $150.00. This is calculated using the Most Favored Nation (MFN) duty rate of 3.0% ad valorem, applied to the declared customs value: 3.0% × $5,000 USD = $150.00. This calculation is based on the rates published in the USITC Harmonized Tariff Schedule, assuming no preferential trade agreements apply and the product is not specifically listed under a more precise subheading within 8103.
Which trade agreements reduce duties for HS 810391?
Several free trade agreements may reduce the applicable duty rate for HS 810391, including the United States-Mexico-Canada Agreement (USMCA), which can result in a duty rate of Free for originating goods from Canada and Mexico. The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) may also offer preferential rates for originating goods from member countries like Japan. Documentation required typically includes a valid Certificate of Origin or a self-certified origin statement, depending on the specific agreement and the exporting country.

The European Union's TARIC system may show different rates depending on specific product characteristics and origin. It is crucial to consult the most current tariff schedule for the importing country, such as the USITC's Harmonized Tariff Schedule or the UK Trade Tariff, for precise rates.
How do preferential trade agreements affect the duty on HS code 810391?
Preferential trade agreements can significantly reduce or eliminate duties on goods classified under HS 810391. For example, under the USMCA (United States-Mexico-Canada Agreement), goods originating from Canada or Mexico may qualify for duty-free entry. Other agreements, like those with Australia (AU), South Korea (KR), or Singapore (SG), may also offer reduced or free rates for qualifying products. Importers must ensure they have the necessary proof of origin documentation to claim these preferential rates.
What documentation is required for importing goods under HS code 810391?
Standard import documentation for HS code 810391 typically includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the origin and any preferential claims, a Certificate of Origin may be mandatory. For unwrought aluminum or aluminum powder, specific certifications regarding purity or composition might be requested by customs authorities to verify compliance with HS 810391's scope. Always check the importing country's specific requirements.
How is the import duty for HS code 810391 calculated, and can you provide an example?
The duty for HS code 810391 is often calculated on an ad valorem basis, meaning a percentage of the declared customs value of the goods. For example, if unwrought aluminum is imported into the US with an MFN duty rate of 4.4% and the declared customs value is $10,000, the import duty would be calculated as: $10,000 (Value) × 0.044 (Duty Rate) = $440. Some specific products under this code might also have specific duties (per unit) or a combination of ad valorem and specific duties, so verifying the exact duty calculation method is essential.
What are the classification criteria for 'Other' unwrought aluminum or aluminum powder under HS 810391?
HS code 810391 is a residual category for unwrought aluminum or aluminum powder not specifically covered by preceding headings within Chapter 81. This typically includes forms like ingots, pigs, or powders that do not meet the specific descriptions of other HS codes in the same chapter. Classification relies on the physical form, purity, and intended use, as defined by the General Rules for the Interpretation of the Harmonized System (GRI). If a product could potentially fit into multiple headings, the one that provides the most specific description for the goods shall be preferred. Consulting the WCO's Explanatory Notes or seeking a binding ruling from customs authorities is advisable for complex cases.
