HS 281990 Other
Quick Answer: HS code 281990, "Other," encompasses various chromium oxides and hydroxides not specifically classified under 281910 (chromium trioxide). This includes less common forms like chromium(II) oxide and hydrated chromium oxides, used in pigments, catalysts, and specialized chemical applications. Duty rates vary significantly: the UK applies a 0.00% ad valorem duty, while the EU's TARIC system shows rates such as 5.50% and 3.70% ad valorem, depending on the specific product and origin. The US Harmonized Tariff Schedule (HTS) lists a general duty rate of 25% ad valorem, with numerous preferential duty-free provisions (e.g., A, AU, CL, KR, SG) under various free trade agreements. Importers should verify the exact subheading and origin to determine the applicable duty rate and leverage any available trade preferences.

How to Classify This HS Code?
What products does HS 281990 cover?
This subheading covers other chromium oxides and hydroxides not specifically provided for in subheading 281910, which is reserved for chromium trioxide. According to the Harmonized System Nomenclature, Heading 2819 encompasses chromium oxides and hydroxides. Subheading 281990 therefore acts as a residual category for all other forms, such as chromium(II) oxide (CrO), chromium(III) oxide (Cr2O3), and various hydrated forms like chromium hydroxide (Cr(OH)3), provided they are chemically defined. This aligns with the interpretative notes from the USITC Harmonized Tariff Schedule and the EU TARIC system, ensuring comprehensive coverage for these inorganic chemical compounds.
What falls outside HS 281990?
The following products are excluded from HS 281990: chromium trioxide, which is specifically classified under HS 281910. Furthermore, chromium compounds that are not oxides or hydroxides, such as chromium sulfates (e.g., HS 283329) or chromium chlorides (e.g., HS 282739), are also excluded and fall under their respective chemical headings. Pigments based on chromium oxides, even if chemically identical, are generally classified under Chapter 32 if they are prepared as pigments, such as chromium green (HS 320620), due to their specific use and preparation, illustrating a common boundary case where end-use or formulation dictates classification.
What are common classification mistakes for HS 281990?
A common error is misclassifying chromium trioxide (chromic acid) under HS 281990 instead of its specific subheading, HS 281910. This often occurs due to a lack of precise chemical identification or an oversight of the specific breakdown within Heading 2819. Another mistake involves classifying prepared chromium oxide pigments, which are mixtures or preparations for specific uses, under this subheading for chemically defined compounds. Such errors violate General Interpretative Rule 1, which mandates classification by the terms of the headings and any relative section or chapter notes, and often General Interpretative Rule 3(a) or 3(b) when dealing with mixtures or composite goods.
How should importers classify products under HS 281990?
The correct procedure for classifying products under HS 281990 involves first confirming that the product is indeed a chromium oxide or hydroxide and not chromium trioxide. Importers and customs brokers should obtain a detailed chemical analysis or specification sheet from the manufacturer, clearly identifying the chemical name, formula, and purity. If the product is any chromium oxide or hydroxide other than chromium trioxide, and it is a chemically defined compound, then HS 281990 is appropriate. Always cross-reference with the latest USITC Harmonized Tariff Schedule or EU TARIC for any specific legal notes or rulings that might affect classification, ensuring compliance and avoiding potential delays or penalties.

FAQ
What is the import duty rate for HS 2819.90 ('Other' chromium oxides and hydroxides) into the United States, and are there any preferential rates available?
For imports into the United States under Harmonized Tariff Schedule (HTS) subheading 2819.90.00.00, the Most Favored Nation (MFN) duty rate, also known as the 'General' rate, is 3.7% ad valorem. However, significant preferential duty treatment is available under various U.S. free trade agreements and preference programs. For eligible goods, a 'Free' (0.00%) duty rate applies when imported 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), provided all rules of origin and documentation requirements are met. Importers should consult the latest USITC HTS for specific country eligibility and chapter notes.
How is HS 2819.90 ('Other' chromium oxides and hydroxides) classified, and what are the key criteria for distinguishing it from other chromium compounds?
HS 2819.90 covers chromium oxides and hydroxides not specifically provided for in subheading 2819.10 (Chromium trioxide). The primary classification criterion is the chemical composition and structure of the chromium compound. This subheading typically includes compounds like chromium(II) oxide (CrO), chromium(III) oxide (Cr2O3) in forms other than trioxide, and various chromium hydroxides. It's crucial to differentiate these from chromium salts (e.g., chromates, dichromates) which fall under different HS headings (e.g., 2841). Laboratory analysis and a clear chemical description are often required to confirm the exact compound and ensure correct classification, adhering to the General Interpretive Rules (GIRs) of the Harmonized System.
What documentation is typically required for importing goods classified under HS 2819.90, especially when claiming preferential duty rates?
Standard import documentation for HS 2819.90 includes a commercial invoice, packing list, and bill of lading or air waybill. To claim preferential duty rates under free trade agreements (e.g., USMCA, KORUS, CAFTA-DR), a valid Certificate of Origin or a declaration of origin is mandatory. This document must demonstrate that the goods meet the specific rules of origin criteria outlined in the respective trade agreement. Importers should also be prepared to provide a Safety Data Sheet (SDS) for chemical products, which helps customs verify the nature of the substance and ensure compliance with any chemical import regulations. Failure to provide accurate and complete documentation can result in duty assessment at the MFN rate or delays in customs clearance.
Are there any specific trade agreements or regulations that particularly impact the import of chromium oxides and hydroxides under HS 2819.90?
Yes, several trade agreements significantly impact the import of goods under HS 2819.90 by offering duty-free access. For instance, the United States has free trade agreements with countries such as Australia, Chile, Colombia, Korea, and Singapore, which provide a 'Free' (0.00%) duty rate for eligible chromium oxides and hydroxides originating from these nations. Importers should also be aware of potential anti-dumping or countervailing duties (AD/CVD) that could apply to certain chromium compounds from specific countries, although currently, none are specifically listed for 2819.90. Additionally, chemical imports may be subject to regulations from agencies like the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA) in the U.S., requiring specific declarations or notifications.
What is the EU TARIC duty rate for HS 2819.90 ('Other' chromium oxides and hydroxides), and how does it compare to other major markets?
For imports into the European Union under TARIC code 2819900000, the Most Favored Nation (MFN) duty rate is 0.00% ad valorem. This 'Free' duty rate applies to goods originating from countries without specific preferential arrangements or subject to general MFN treatment. This contrasts with the U.S. MFN rate of 3.7% for the same subheading. The UK Global Tariff (UKGT) also lists a 0.00% duty rate for HS 2819.90.00.00. Importers should always verify the latest applicable rates through the EU TARIC database or the UK Trade Tariff, respectively, as duty rates and specific measures can be subject to change.
