HS 284190 Other
Quick Answer: HS code 284190, "Other," encompasses a diverse range of complex inorganic salts of oxometallic or peroxometallic acids, specifically those not classified under more specific headings within Chapter 28. This includes various tungstates, molybdates, vanadates, and other metallic salts crucial for industrial applications like catalysts, pigments, and chemical reagents. Duty rates vary significantly: the UK applies a 4.00% ad valorem rate across many sub-lines, while the EU generally imposes 4.60% ad valorem. The US rates are highly disparate, ranging from 5.5% to 40% ad valorem, with numerous sub-lines eligible for duty-free treatment under various Free Trade Agreements (e.g., A, AU, BH, CL, KR). Importers and customs brokers must meticulously verify the specific product's chemical composition and origin to determine the correct sub-heading and applicable preferential duty rates, as misclassification can lead to penalties or missed savings.

How to Classify This HS Code?
What products does HS 284190 cover?
This subheading covers "Other" salts of oxometallic or peroxometallic acids, specifically those not enumerated in subheadings 2841.10 through 2841.80. This includes a diverse range of inorganic chemical compounds, such as salts of molybdates, tungstates, vanadates, niobates, tantalates, and other oxometallic acids, provided they are not specifically mentioned elsewhere in Heading 2841. The WCO Harmonized System Explanatory Notes for Heading 2841 clarify that this residual subheading captures all other complex inorganic salts of metallic acids not otherwise specified, aligning with definitions found in the USITC Harmonized Tariff Schedule and the EU TARIC system.
What falls outside HS 284190?
The following products are excluded from HS 284190: chromates, dichromates, and peroxochromates (classified under 2841.30); manganites, manganates, and permanganates (classified under 2841.61 or 2841.69); molybdates (classified under 2841.70); and tungstates (classified under 2841.80). Additionally, certain compounds that might appear similar but are not salts of oxometallic or peroxometallic acids, or those that are organic compounds, would be classified elsewhere in Chapter 28 or Chapter 29, respectively. For instance, simple metallic oxides or hydroxides are typically found in earlier headings of Chapter 28, not under 2841.
What are common classification mistakes for HS 284190?
A common error is misclassifying specific oxometallic salts that have their own dedicated subheadings within 2841 into the "Other" category of 284190. For example, classifying sodium molybdate under 284190 instead of its correct subheading 2841.70 is a frequent mistake. This often occurs due to insufficient attention to the specific chemical name and composition, leading to a failure to apply General Interpretative Rule (GRI) 1, which mandates classification according to the terms of the headings and any relative section or chapter notes. Importers must ensure they precisely identify the chemical compound to avoid such misclassifications.
How should importers classify products under HS 284190?
The correct procedure for classifying products under HS 284190 involves a meticulous review of the chemical's exact composition and nomenclature. Importers and customs brokers should first verify that the product is indeed a salt of an oxometallic or peroxometallic acid. Next, they must systematically check all specific subheadings within Heading 2841 (2841.10 through 2841.80) to ensure the product is not explicitly covered elsewhere. Only after confirming that the product does not fit into any more specific subheading should it be classified under 284190, applying GRI 1 and referencing the WCO Explanatory Notes for Heading 2841 to confirm its residual nature.

FAQ
What are the typical import duty rates for products classified under HS 2841.90 ('Other' salts of oxometallic or peroxometallic acids, excluding those of subheadings 2841.10 to 2841.80) in major markets?
The Most Favored Nation (MFN) duty rates for HS 2841.90 generally range as follows: In the United States, the MFN duty rate is 4.0% ad valorem (Source: USITC HTSUS). For the European Union (EU TARIC), the MFN duty rate is 4.6% ad valorem. Similarly, the UK Global Tariff (UKGT) also applies a 4.6% ad valorem duty. It is crucial for importers to verify the specific duty rate applicable at the time of importation, as rates can be subject to change or specific trade policy measures.
Are there any preferential duty rates available for HS 2841.90 under common trade agreements?
Yes, preferential duty rates, including 'Free' status, are available for HS 2841.90 under various trade agreements, provided the goods meet the respective Rules of Origin. For instance, in the United States, imports from countries such as Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), and Singapore (SG) may qualify for duty-free treatment under their respective Free Trade Agreements (FTAs). Importers should consult the specific FTA text and ensure proper origin documentation (e.g., a Certificate of Origin) is obtained and presented to customs authorities to claim preferential treatment.
What are the key classification criteria for determining if a product falls under HS 2841.90, especially given its 'Other' designation?
HS 2841.90 is a residual subheading for 'Other' salts of oxometallic or peroxometallic acids, meaning it covers those not specifically provided for in subheadings 2841.10 through 2841.80. Classification hinges on the chemical composition: the product must be a salt of an oxometallic or peroxometallic acid. Importers and customs brokers must ensure the product's chemical name and CAS (Chemical Abstracts Service) number are accurately identified. If the product is, for example, a chromate, permanganate, molybdate, tungstate, vanadate, or niobate, it would likely fall into one of the more specific subheadings (2841.20 to 2841.80). If it is a salt of an oxometallic or peroxometallic acid not explicitly named in those subheadings, then 2841.90 would be the appropriate classification. A detailed chemical analysis or specification sheet is often necessary to confirm the exact nature of the salt.
What specific documentation is typically required by customs for imports classified under HS 2841.90?
Standard import documentation includes a commercial invoice, packing list, and bill of lading or air waybill. For chemical products like those in HS 2841.90, additional documentation is often critical. This may include a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) to provide information on the chemical's properties and handling. A Certificate of Analysis (CoA) is also frequently requested to confirm the chemical composition and purity. If claiming preferential duty rates, a valid Certificate of Origin (e.g., FTA certificate, GSP Form A) is mandatory. Importers should also be prepared to provide detailed product specifications or technical data sheets if requested by customs to verify classification.
