HS 282090 Other
Quick Answer: HS Code 2820.90, "Other," encompasses various oxides of manganese not specifically classified elsewhere within heading 2820. This includes less common manganese oxides beyond the primary dioxide, such as trimanganese tetraoxide (Mn3O4) or manganese(II) oxide (MnO), used in diverse industrial applications like ceramics, pigments, and chemical synthesis. Duty rates vary significantly: The UK Trade Tariff generally applies 0.00% ad valorem. The EU TARIC system shows rates ranging from 0.00% to 5.50% ad valorem, depending on the specific product. The US Harmonized Tariff Schedule (HTSUS) lists a general duty rate of 4.7% ad valorem, with certain specific manganese oxides subject to 25%. However, many US preferential trade programs (e.g., A, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG) allow for duty-free entry. Importers should verify the exact chemical composition and origin to determine the applicable duty rate and eligibility for preferential treatment.

How to Classify This HS Code?
What products does HS 282090 cover?
This subheading covers manganese oxides other than manganese dioxide (manganese(IV) oxide), which is specifically classified under HS 282010. According to the Harmonized System Nomenclature, as interpreted by the World Customs Organization (WCO) and reflected in the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, HS 282090 encompasses various other chemical compounds of manganese and oxygen. This includes, for example, dimanganese trioxide (Mn2O3), trimanganese tetraoxide (Mn3O4), and manganese(II) oxide (MnO), provided they are chemically defined and not mixtures or preparations falling under other chapters.
What falls outside HS 282090?
The following products are excluded from HS 282090: manganese dioxide (manganese(IV) oxide), which is specifically classified under HS 282010. Additionally, manganese ores and concentrates, even if containing manganese oxides, are classified under Chapter 26, specifically HS 2602. Furthermore, certain preparations containing manganese oxides but not being chemically defined pure compounds, such as pigments or catalysts, may fall under Chapters 32 or 38, respectively, depending on their composition and intended use. For instance, manganese oxide-based pigments are typically found in Chapter 32.
What are common classification mistakes for HS 282090?
A common error is misclassifying manganese dioxide (MnO2) under HS 282090 instead of its specific subheading, HS 282010. Importers sometimes overlook the explicit distinction within Heading 2820, leading to incorrect duty rates and compliance issues. Another frequent mistake involves classifying manganese ores, which are naturally occurring mixtures, as chemically defined manganese oxides under this subheading. General Interpretative Rule (GRI) 1 dictates that classification should be determined according to the terms of the headings and any relative section or chapter notes, emphasizing the need for precise chemical identification.
How should importers classify products under HS 282090?
The correct procedure for classifying products under HS 282090 involves first confirming that the substance is a chemically defined manganese oxide and not manganese dioxide. Importers and customs brokers should obtain a detailed chemical analysis or certificate of analysis (CoA) from the manufacturer, clearly stating the specific chemical formula (e.g., Mn2O3, Mn3O4, MnO) and purity. This documentation is crucial for demonstrating that the product is indeed "other" than manganese dioxide. Always cross-reference with the WCO Explanatory Notes for Heading 2820 and consult the official USITC HTSUS or EU TARIC for the most current and precise definitions and duty rates.

FAQ
What is the import duty rate for products classified under HS 2820.90 in the United States, and are there any preferential rates available?
For products classified under Harmonized System (HS) subheading 2820.90 ('Manganites, other'), the Most Favored Nation (MFN) duty rate in the United States is 4.7% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). However, many preferential trade agreements offer duty-free treatment. Importers may claim a 'Free' duty rate if the goods originate from countries with which the U.S. has a Free Trade Agreement (FTA), such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG), among others. It is crucial to ensure compliance with the specific Rules of Origin for the applicable FTA to qualify for preferential treatment.
What specific types of chemical compounds are classified under HS 2820.90, given its 'Other' designation, and what are the key classification criteria?
HS subheading 2820.90 is designated as 'Other' within heading 2820, which covers 'Manganese oxides.' This 'Other' category typically includes manganese oxides not specifically provided for in subheadings 2820.10 (Manganese dioxide) or 2820.90 (Manganites). Therefore, 2820.90 would encompass various manganites and other complex manganese oxides that do not fit the specific chemical definitions or purities of manganese dioxide. Classification relies on the precise chemical composition and structure of the compound. Importers should refer to the Explanatory Notes to the Harmonized System for Chapter 28 and specifically heading 2820 for detailed guidance on distinguishing between different manganese compounds. A Certificate of Analysis (CoA) or other chemical documentation is often essential to support the classification.
Are there any specific documentation requirements or regulatory considerations for importing chemical products under HS 2820.90 into the U.S.?
Yes, beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), importing chemical products under HS 2820.90 may require additional documentation and compliance with specific regulations. A Safety Data Sheet (SDS) is typically required for chemical imports, providing crucial information on hazards, handling, and emergency procedures. Depending on the specific chemical compound, other U.S. agencies such as the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA) or the Food and Drug Administration (FDA) may have reporting or approval requirements. Importers should verify if their specific product is subject to TSCA notification or other agency controls prior to importation.
How do common trade agreements, such as the USMCA or EU-U.S. trade relations, affect the duty rates for HS 2820.90?
While the U.S. does not have a comprehensive free trade agreement with the European Union, the duty rate for HS 2820.90 from the EU would generally be the MFN rate of 4.7% ad valorem. For countries party to the United States-Mexico-Canada Agreement (USMCA), such as Canada and Mexico, goods originating from these countries and meeting the USMCA Rules of Origin would qualify for duty-free treatment (0.00% ad valorem). It is imperative for importers to ensure that the Certificate of Origin or other origin documentation is accurately prepared and available to claim preferential duty rates under USMCA or any other applicable FTA.
