HS 284290 Other
Quick Answer: HS 284290, "Other," encompasses a diverse range of inorganic chemical compounds not specified elsewhere in Chapter 28. This residual heading typically covers complex or less common inorganic salts and compounds. For importers and exporters, duty rates vary significantly by jurisdiction and specific product. The UK Trade Tariff generally applies a 0.00% duty rate across its 11 subheadings. The EU TARIC system shows rates predominantly at 5.30% ad valorem, though some subheadings are 0.00%. In the US, rates range from 3.1% to 25% ad valorem, with numerous Free Trade Agreement (FTA) preferential rates available for eligible goods from countries like Korea, Australia, and Israel. Due to its "Other" nature, precise classification within this heading requires careful review of product composition against national tariff schedules to ensure correct duty assessment and compliance.

How to Classify This HS Code?
What products does HS 284290 cover?
This subheading covers "Other" inorganic compounds of non-metals or of metals, not elsewhere specified or included, falling under Heading 2842. Specifically, it encompasses a diverse range of inorganic compounds that do not fit into the more specific subheadings of 2842. This includes, for example, certain inorganic phosphides, carbides, nitrides, azides, silicides, and borides, provided they are not specifically enumerated in other headings or subheadings of Chapter 28. The WCO Harmonized System Explanatory Notes for Heading 2842 clarify that this heading serves as a residual category for inorganic compounds not covered by more specific provisions, and subheading 284290 further refines this for those "other" compounds. For instance, compounds like certain complex inorganic salts or double salts, if not specifically provided for elsewhere, would fall here, as detailed in the USITC Harmonized Tariff Schedule (HTS) and EU TARIC classifications.
What falls outside HS 284290?
The following products are excluded from HS 284290: inorganic compounds that are specifically provided for in other headings or subheadings of Chapter 28 or other chapters of the Harmonized System. For example, carbides of silicon (2849.20), borides (2849.90), nitrides (2850.00), phosphides (2850.00), and silicides (2850.00) are explicitly classified under their respective specific headings, even though they are inorganic compounds. Furthermore, compounds of precious metals (Chapter 71), radioactive elements (2844), and isotopes (2845) are also excluded due to their specific nature and dedicated classification provisions. Complex inorganic pigments (Chapter 32) and certain inorganic compounds with specific industrial uses, such as catalysts (Chapter 38), are also typically excluded, as their primary function or composition dictates classification elsewhere, preventing their inclusion in this residual "other" category.
What are common classification mistakes for HS 284290?
A common error is misclassifying inorganic compounds that have more specific provisions elsewhere in Chapter 28 or even in other chapters of the HS, defaulting them to 284290. Importers often overlook the specific headings for carbides, nitrides, phosphides, and silicides (e.g., 2849, 2850), incorrectly assuming that since they are "other" inorganic compounds, they belong in 284290. This violates General Rule of Interpretation (GRI) 1, which states that classification shall be determined according to the terms of the headings and any relative section or chapter notes. Another mistake involves classifying complex inorganic compounds with a primary function, such as pigments or catalysts, into 284290, when their functional characteristics dictate classification under Chapter 32 or 38, respectively. Careful review of the WCO Explanatory Notes and the specific chemical composition and intended use is crucial to avoid these common misclassifications.
How should importers classify products under HS 284290?
The correct procedure for classifying products under HS 284290 involves a systematic review of the product's chemical composition and a thorough application of the General Rules of Interpretation (GRIs). Importers and customs brokers should first identify the exact chemical nature of the inorganic compound. Next, they must consult Chapter 28 and other relevant chapters of the Harmonized System to determine if the compound is specifically enumerated in any other heading or subheading. Only if the compound is not specifically provided for elsewhere, and it is an inorganic compound of non-metals or metals, should Heading 2842 be considered. Finally, if it does not fit into the more specific subheadings under 2842, then 284290, as the "other" residual category, becomes appropriate. Consulting the WCO Explanatory Notes for Heading 2842 and cross-referencing with official national tariffs like the USITC HTS or EU TARIC is essential for accurate and compliant classification.

FAQ
What is the import duty rate for products classified under HS 2842.90 in major markets, and are there any preferential rates available?
The Most Favored Nation (MFN) duty rates for HS 2842.90 ('Other' inorganic compounds, not elsewhere specified or included) vary significantly by importing country. For instance, the United States (USITC) generally applies a 'Free' (0.00% ad valorem) MFN duty rate. The European Union (EU TARIC) also typically applies a 0.00% MFN duty rate. However, other countries may have different rates, such as 5.30% or 3.1% ad valorem in some jurisdictions, and up to 25% in others. Importers should consult the specific tariff schedule of the destination country. Preferential duty rates are widely available under various Free Trade Agreements (FTAs). For example, imports into the U.S. under HS 2842.90 may qualify for 'Free' duty under agreements with Australia (AU), Bahrain (BH), Chile (CL), Colombia (CO), Israel (IL), Jordan (JO), Korea (KR), Morocco (MA), Oman (OM), Panama (PA), Peru (PE), Singapore (SG), and others, provided all rules of origin are met. Importers should verify eligibility for specific preferential programs (e.g., GSP, FTAs) by checking the relevant trade agreement text and providing proper documentation like a certificate of origin.
What are the key classification criteria for products under HS 2842.90, given its 'Other' designation?
HS 2842.90 is a residual 'Other' subheading within Chapter 28, which covers inorganic chemicals. Products fall under this subheading only if they are inorganic compounds not specifically provided for in any other heading of Chapter 28 (28.01 to 28.41) or in other subheadings of heading 28.42 (e.g., 2842.10 for double or complex silicates). Classification requires a thorough analysis of the chemical composition and specific identity of the compound. If a product is a distinct inorganic compound and does not fit a more specific HS code, it defaults to 2842.90. Importers and customs brokers must ensure that the product is indeed an 'inorganic compound' and that no more specific classification exists, referencing the Harmonized System Explanatory Notes (HSEN) for Chapter 28 and heading 28.42 for guidance.
What documentation is typically required for customs clearance of goods classified under HS 2842.90?
Standard import documentation is required for goods under HS 2842.90, including a commercial invoice, packing list, and bill of lading or air waybill. Given the chemical nature of the goods, additional documentation may be necessary: a Safety Data Sheet (SDS) is often required by regulatory agencies for hazard communication and may be requested by customs. A Certificate of Analysis (CoA) detailing the chemical composition and purity may also be beneficial or required by specific regulations. If claiming preferential duty rates (e.g., under an FTA), a valid Certificate of Origin (e.g., EUR.1, NAFTA/USMCA Certificate, or other FTA-specific declaration) is mandatory. Importers should confirm specific requirements with the customs authority of the importing country, as these can vary.
Are there any specific import restrictions, licenses, or special permits for chemical compounds under HS 2842.90?
While HS 2842.90 covers a broad range of 'other' inorganic compounds, specific import restrictions, licenses, or permits can apply depending on the exact chemical identity and its intended use. For example, certain inorganic compounds may be precursors for controlled substances, dual-use goods, or subject to environmental regulations (e.g., REACH in the EU, TSCA in the U.S.). Importers must verify if the specific chemical compound within 2842.90 is listed under any national or international control regimes, such as the Chemical Weapons Convention (CWC), the Montreal Protocol, or national hazardous substance lists. It is crucial for importers to identify the precise chemical name (e.g., CAS number) and consult relevant regulatory bodies in the importing country to determine if any specific permits, registrations, or declarations are required prior to shipment.
