HS 293090 Other
Quick Answer: HS code 293090, titled "Other," is a residual classification within Chapter 29 for organo-sulphur compounds not specifically covered by other subheadings. This broad category encompasses a diverse range of complex organic chemicals containing sulfur, such as thiols, thioethers, and sulfones, used in pharmaceuticals, agrochemicals, and industrial processes. Duty rates vary significantly. In the UK and EU, many subheadings under 293090 are subject to a 0.00% ad valorem duty. Conversely, the US tariff schedule presents a wider range, including 6.5% ad valorem, "Free" for goods originating from numerous Free Trade Agreement partners (e.g., Australia, Korea), and specific compound duties like 15.4¢/kg + 64.5% ad valorem for certain products. Importers and customs brokers must meticulously classify goods to the 10-digit level to determine the precise duty rate and leverage applicable trade preferences.

How to Classify This HS Code?
What products does HS 293090 cover?
This subheading covers other organo-sulphur compounds not elsewhere specified or included in subheadings 2930.10 through 2930.80. As per the Harmonized System Nomenclature, specifically Chapter 29, this residual subheading captures a diverse range of organic compounds containing sulfur atoms directly bonded to carbon atoms, provided they do not fall under more specific provisions within Heading 2930 or other chapters. Examples include various thiols, thioethers, sulfoxides, and sulfones that are not specifically enumerated. The scope is defined by exclusion, encompassing all remaining organo-sulphur compounds that meet the general chemical structure requirements of the heading but lack a dedicated subheading. Importers should consult the official USITC Harmonized Tariff Schedule and EU TARIC for detailed national interpretations.
What falls outside HS 293090?
The following products are excluded from HS 293090: specific organo-sulphur compounds that have their own dedicated subheadings within 2930, such as thiocarbamates and dithiocarbamates (2930.20), mercaptobenzothiazole (2930.30), and methionine (2930.40). Additionally, certain sulfur-containing compounds that are not "organic" in the sense of Chapter 29, or where the sulfur is not directly bonded to carbon, would be excluded. For instance, inorganic sulphates or sulphides fall under Chapter 28. Polymers of organo-sulphur compounds are also excluded, as they are typically classified in Chapter 39. Furthermore, medicaments containing organo-sulphur compounds, when put up in measured doses or for retail sale, are classified in Heading 3004, not Chapter 29, due to their specific use and presentation.
What are common classification mistakes for HS 293090?
A common error is misclassifying specific organo-sulphur compounds into 293090 when they have a more specific subheading within 2930. This often occurs when an importer overlooks the detailed product descriptions of subheadings 2930.10 through 2930.80, leading to incorrect application of General Interpretative Rule (GRI) 1. For example, classifying a dithiocarbamate under "other" instead of 2930.20 is a frequent mistake. Another pitfall is failing to distinguish between pure chemical compounds and mixtures or preparations. If an organo-sulphur compound is part of a mixture or preparation, its classification might be governed by GRI 3, potentially leading to classification in a different heading or chapter, especially if it's a functional mixture for a specific use, such as a pesticide or a pharmaceutical intermediate.
How should importers classify products under HS 293090?
The correct procedure for classifying products under HS 293090 involves a systematic review of the Harmonized System. Importers and customs brokers should first verify that the product is indeed an organo-sulphur compound and meets the general criteria for Chapter 29. Next, meticulously check all specific subheadings within Heading 2930 (2930.10 through 2930.80) to ensure the product is not explicitly covered elsewhere. This requires a detailed chemical analysis of the product's structure and composition. If the compound does not fit any more specific subheading, then, and only then, should 293090 be considered. Always consult the Explanatory Notes to the HS for Heading 2930 and Chapter 29, and cross-reference with national tariff schedules like the USITC HTS or EU TARIC for any binding rulings or specific national interpretations to ensure accurate and compliant classification.

FAQ
What is the general import duty rate for products classified under HS 2930.90 in the United States, and are there any preferential rates available?
For products classified under Harmonized System (HS) subheading 2930.90 ('Other' organo-sulphur compounds) imported into the United States, the Column 1 'General' Most Favored Nation (MFN) duty rate is 6.5% ad valorem, as per the Harmonized Tariff Schedule of the United States (HTSUS). However, many preferential duty rates are available through various Free Trade Agreements (FTAs) and special programs. For eligible goods, a 'Free' duty rate (0.00%) may apply under agreements with 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). Importers should consult the HTSUS and ensure proper documentation, such as a Certificate of Origin, to claim these preferential rates.
What are the key classification criteria for determining if a chemical compound falls under HS 2930.90, especially given its 'Other' designation?
HS subheading 2930.90 is a residual 'Other' category within Chapter 29, specifically for 'Organo-sulphur compounds'. The primary classification criteria are that the compound must be an organic chemical and must contain sulfur in its molecular structure. It must not be specifically provided for in any of the preceding subheadings within HS 2930 (e.g., thiocarbamates, dithiocarbamates, thiuram mono-, di- or tetrasulphides, methionine, or 2-(N,N-diethylamino)ethanethiol). Classification requires a detailed chemical analysis to confirm the presence of sulfur and to rule out more specific classifications within Chapter 29. Importers should refer to the Explanatory Notes to the Harmonized System for Chapter 29 for detailed guidance on the scope of organo-sulphur compounds.
What specific documentation is required for importing chemical compounds under HS 2930.90, particularly for customs clearance and claiming preferential duty rates?
For customs clearance of chemical compounds under HS 2930.90, standard import documentation is required, including a commercial invoice, packing list, and bill of lading or air waybill. For chemical products, a Safety Data Sheet (SDS) is often requested by customs or other regulatory agencies (e.g., EPA in the US) to assess potential hazards and ensure compliance with chemical control regulations. To claim preferential duty rates under a Free Trade Agreement (FTA), a valid Certificate of Origin (or equivalent declaration) is mandatory, demonstrating that the goods meet the specific Rules of Origin criteria of the respective agreement. Importers should also be prepared to provide detailed chemical descriptions or structural formulas if requested by customs to verify classification.
Are there any specific trade agreements or programs that offer duty-free treatment for HS 2930.90 that importers should be aware of beyond standard FTAs?
Beyond the bilateral Free Trade Agreements (FTAs) that offer 'Free' duty rates (e.g., with Australia, Korea, Peru), importers should also consider broader preferential programs. For example, the Generalized System of Preferences (GSP) may offer duty-free treatment for certain products from eligible developing countries, although the product coverage and country eligibility can change. While the provided sample rates indicate 'Free' for several FTAs, it's crucial to verify the current status and specific product eligibility under programs like GSP or other regional agreements (e.g., CAFTA-DR for Central American countries) by checking the latest HTSUS and relevant trade agreement texts. The 'Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)' notation typically refers to specific tariff treatments under various trade agreements and programs, where 'A' often denotes GSP eligibility, and other letters correspond to specific country agreements.
