How to Classify This HS Code?
What products does HS 790390 cover?
This subheading covers "other" zinc and articles of zinc not specifically enumerated under HS 7903.10 (zinc dust and powders) or HS 7903.90.0000 (zinc waste and scrap). According to the World Customs Organization (WCO) Harmonized System Explanatory Notes, this category is residual and captures various forms of zinc and its alloys that do not fit into more specific classifications within Heading 7903, such as certain unwrought zinc alloys or specific semi-finished zinc products not otherwise detailed.
What falls outside HS 790390?
The following products are excluded from HS 790390: zinc dust and powders (classified under HS 7903.10), and zinc waste and scrap (classified under HS 7903.90.0000). Additionally, articles of zinc that are further manufactured or incorporated into more complex goods, such as zinc-plated steel, zinc oxide, or zinc compounds, would be classified under different headings based on their specific nature and function, rather than under this residual heading for unwrought zinc or basic forms.
What are common classification mistakes for HS 790390?
A common error is misclassifying zinc waste and scrap under HS 790390 when it should be specifically classified under HS 7903.90.0000, which is dedicated to such materials. Another mistake involves classifying zinc alloys that have undergone significant processing or are presented as finished articles under this residual heading, rather than under headings for specific semi-finished or finished goods as per General Rule of Interpretation (GRI) 1 and GRI 3.
How should importers classify products under HS 790390?
The correct procedure for classifying products under HS 790390 involves first determining if the product is zinc or an article of zinc. Subsequently, it must be verified that the product is not specifically covered by HS 7903.10 (zinc dust and powders) or HS 7903.90.0000 (zinc waste and scrap). If it is unwrought zinc or a basic form not otherwise specified, and it is not a finished article, then HS 790390 is the appropriate classification.
How is the duty calculated for products under HS 790390?
A shipment of 10,000 kilograms of unwrought zinc alloy, 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 calculation is based on the rates published in the USITC Harmonized Tariff Schedule (HTS) for subheading 7903.90.
Which trade agreements reduce duties for HS 790390?
Several free trade agreements may reduce the applicable duty rate for HS 790390, including the United States-Mexico-Canada Agreement (USMCA), which can provide for duty-free entry for originating goods. The United Kingdom's Generalized System of Preferences (GSP) may also offer reduced or zero duties for goods from certain developing countries. Top origin countries benefiting from such preferences could include Mexico, Canada, and various developing nations. Documentation typically required includes a USMCA Certificate of Origin or a GSP Form A, depending on the specific agreement and jurisdiction.

FAQ
What are the typical import duty rates for HS code 790390, and how do preferential rates apply?
HS code 790390 covers 'Other' zinc and articles thereof. The Most Favored Nation (MFN) duty rate can vary, for example, it might be 2.50% ad valorem. However, preferential rates under various trade agreements significantly reduce or eliminate duties. For instance, under certain agreements (indicated by codes like A, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG), the duty rate may be Free. It is crucial to consult the specific tariff schedule of the importing country and verify eligibility for preferential treatment based on the origin of the goods and the applicable trade agreement.
How is the duty calculated for HS code 790390 when a specific rate is applied, such as 0.5¢/kg?
When a specific duty rate is applied, such as 0.5¢/kg, the duty is calculated based on the net weight of the imported goods. For example, if you import 10,000 kilograms of zinc products classified under HS 790390 with a duty rate of 0.5¢/kg, the total duty would be 10,000 kg * 0.5¢/kg = 5,000¢. This amount would then be converted to the national currency. It's important to note that some classifications might have compound duties (a combination of ad valorem and specific rates).
What documentation is typically required for importing goods classified under HS code 790390?
For HS code 790390, standard import documentation usually includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the country of origin and destination, a certificate of origin may be required to claim preferential duty rates under trade agreements. For certain zinc products, specific quality certifications or compliance with environmental regulations might also be necessary. Always verify the specific documentation requirements with the customs authority of the importing country.
What are the classification criteria for determining if a zinc product falls under 'Other' (HS 790390)?
HS code 790390 is a residual category for zinc and articles thereof. It applies to products that are not specifically covered by other subheadings within Chapter 79 of the Harmonized System. This typically includes unwrought zinc that does not meet the specifications for higher-rated subheadings, or articles of zinc that are not otherwise classified. To correctly classify, one must first review the preceding subheadings (e.g., 7901, 7902, 7904, 7905, 7907) to ensure the product does not fit into a more specific category. Consult the Explanatory Notes to the Harmonized System for detailed guidance.
Which major trade agreements commonly offer preferential duty rates for HS code 790390, and how can importers leverage them?
Several trade agreements can provide preferential duty rates for HS code 790390. Examples include agreements with countries or blocs such as Australia (AU), the European Union (E), South Korea (KR), and many others often denoted by specific country codes in tariff schedules. To leverage these agreements, importers must ensure the goods meet the rules of origin stipulated in the relevant trade agreement. This typically requires a valid Certificate of Origin issued by the exporter or producer in the partner country, demonstrating that the goods qualify for preferential treatment. Importers should consult the specific trade agreement text and the customs authority's guidelines for compliance.
