HS 292090 Other
Quick Answer: HS code 2920.90, "Other," encompasses a diverse range of esters of other inorganic acids (excluding those of hydrogen halides) and their salts, along with their halogenated, sulfonated, nitrated, or nitrosated derivatives, not specifically classified elsewhere within heading 2920. This includes various complex organic chemicals used in pharmaceuticals, agrochemicals, and specialty chemical manufacturing. Importers and exporters should note the varying duty rates: the UK applies a 6.00% ad valorem duty, while the EU imposes 6.50% ad valorem. In the US, rates range from 6.5% ad valorem to duty-free under various preferential trade agreements (e.g., A, AU, KR), but can also be as high as 15.4¢/kg + 64.5% for certain products. Due to the broad nature of "Other," precise product identification and chemical composition are critical for accurate classification and duty assessment. Consult specific national tariff schedules (e.g., UK Trade Tariff, EU TARIC, USITC HTSUS) for sub-heading details.

How to Classify This HS Code?
What products does HS 292090 cover?
This subheading covers "Other" esters of other inorganic acids of non-metals (excluding esters of hydrogen halides) and their salts; their halogenated, sulfonated, nitrated or nitrosated derivatives, not elsewhere specified or included in subheadings 2920.11, 2920.19, 2920.21, 2920.22, 2920.23, 2920.24, 2920.29, 2920.30, or 2920.90. It acts as a residual category for compounds that fit the general description of Heading 2920 but are not specifically enumerated in the more precise subheadings. Examples include various organic phosphites, phosphonates, and other complex esters of inorganic acids of non-metals, provided they are not specifically excluded elsewhere in Chapter 29, as per the WCO Harmonized System Explanatory Notes and the USITC Harmonized Tariff Schedule.
What falls outside HS 292090?
The following products are excluded from HS 292090: Esters of thiophosphoric acid (e.g., parathion, malathion), which are specifically classified under subheading 2920.11 or 2920.19. Also excluded are phosphite esters, such as trimethyl phosphite or triethyl phosphite, which fall under subheading 2920.21. Dimethyl phosphite and diethyl phosphite are classified under 2920.22. Additionally, tri(2-ethylhexyl) phosphite is classified under 2920.23, and triphenyl phosphite is under 2920.24. Other phosphite esters are found in 2920.29. Dimethyl methylphosphonate is classified under 2920.30. Any compounds that are not esters of inorganic acids of non-metals, or their derivatives, would also be excluded and classified according to their specific chemical structure elsewhere in Chapter 29 or other relevant chapters.
What are common classification mistakes for HS 292090?
A common error is misclassifying specific esters of inorganic acids of non-metals into 292090 when they have a more precise subheading within Heading 2920. For instance, classifying a phosphite ester under 292090 instead of its specific subheading like 2920.21 (trimethyl phosphite) or 2920.29 (other phosphite esters) is a frequent mistake. This often occurs due to insufficient analysis of the chemical structure and a failure to apply General Rule of Interpretation (GRI) 6, which mandates that classification of goods in subheadings shall be determined according to the terms of those subheadings and any relative subheading notes, and mutatis mutandis, to the GRIs. Importers sometimes default to the "Other" category without thoroughly checking for more specific provisions, leading to incorrect duty rates and potential compliance issues.
How should importers classify products under HS 292090?
The correct procedure for classifying products under HS 292090 involves a systematic review of the chemical composition and structure. Importers and customs brokers must first identify if the product is an ester of an inorganic acid of a non-metal, or a derivative thereof, as defined by Heading 2920. Subsequently, they must meticulously check all specific subheadings within 2920 (e.g., 2920.11, 2920.19, 2920.21, 2920.22, 2920.23, 2920.24, 2920.29, 2920.30) to ensure the product is not specifically enumerated. Only if the product definitively does not fit any of the more specific subheadings should 292090 be considered. Consulting the WCO Harmonized System Explanatory Notes for Heading 2920 and relevant national tariff schedules (e.g., USITC HTS, EU TARIC, UK Trade Tariff) is crucial to ensure accurate classification and compliance with trade regulations.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 2920.90 in key markets?
The MFN (Most Favored Nation) import duty rates for HS 2920.90 'Other' esters of other inorganic acids of non-metals (excluding esters of hydrogen halides) vary by importing country. For example, the general MFN duty rate in the United States is 6.5% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). In the European Union, the TARIC database indicates a common customs duty of 6.5% ad valorem. The UK Global Tariff also lists a duty rate of 6.5% ad valorem. Importers should always verify the current rates through the official USITC HTSUS, EU TARIC, or UK Trade Tariff portals, respectively, as rates can be subject to change.
What are the key classification criteria for products falling under HS 2920.90, and what types of chemicals are typically included?
HS 2920.90 is the residual 'Other' subheading for 'Esters of other inorganic acids of non-metals (excluding esters of hydrogen halides) and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives.' This heading specifically covers organic chemical compounds that are esters formed from inorganic acids of non-metals, excluding those derived from hydrogen halides (which are typically found in HS 2918 or other specific headings). Examples of chemicals typically classified here include various phosphites, phosphonates, and other complex esters not specifically provided for in subheadings 2920.11 through 2920.90. Classification relies on the chemical structure, specifically the ester linkage to an inorganic acid of a non-metal. Importers should provide detailed chemical names, CAS numbers, and structural formulas to customs authorities to ensure accurate classification.
Which preferential trade agreements offer duty-free or reduced rates for goods under HS 2920.90 when imported into the United States?
For imports into the United States, several Free Trade Agreements (FTAs) and preferential programs offer duty-free treatment for goods classified under HS 2920.90, provided the rules of origin are met. Based on the HTSUS, goods 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 be eligible for 'Free' duty rates under their respective FTAs. Additionally, certain Generalized System of Preferences (GSP) beneficiary countries might also qualify for duty-free entry (indicated by 'A' in the 'Special' column of the HTSUS). Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim these preferential tariffs.
What specific documentation is required by customs authorities for importing chemicals under HS 2920.90?
Beyond standard shipping documents like the commercial invoice, packing list, and bill of lading/air waybill, importing chemicals under HS 2920.90 often requires additional specific documentation to ensure compliance and safety. This may include: 1. Safety Data Sheet (SDS): Essential for hazardous materials, providing information on properties, hazards, and safe handling. 2. Certificate of Analysis (CoA): Verifies the chemical composition and purity, which can be crucial for classification and regulatory compliance. 3. Chemical Abstract Service (CAS) Registry Number: A unique identifier for chemical substances, highly recommended for clear identification. 4. Import Licenses or Permits: Depending on the specific chemical and its end-use, permits from agencies like the Environmental Protection Agency (EPA) or other chemical control authorities may be necessary. Importers should consult their customs broker and relevant national regulations (e.g., TSCA in the US, REACH in the EU) prior to shipment.
