HS 283090 Other

The Most Favored Nation (MFN) import duty rates for HS 2830.90 ('Other' sulfides, polysulfides, dithionites, sulfoxylates, thiosulfates, etc.) vary significantly by importing country. For example, the United States (USITC) applies an MFN duty rate of 3.7% ad valorem for subheading 2830.90.00.00. The European Union (EU TARIC) generally applies an MFN duty rate of 4.0% ad valorem for various subheadings under 2830.90, such as 2830.90.85.00 for other inorganic thiosulfates. The United Kingdom Trade Tariff also lists MFN rates around 4.0% ad valorem. Preferential duty rates may be available under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) schemes. For instance, under the U.S. Generalized System of Preferences (GSP), certain products from eligible developing countries may enter duty-free. Importers should consult the specific trade agreement rules of origin and the tariff database of the importing country (e.g., USITC HTS, EU TARIC, UK Trade Tariff) to determine eligibility for preferential treatment and the exact applicable rate.

HS 2830.90 is a residual 'Other' subheading within Heading 28.30, which covers 'Sulfides of non-metals or of metals, whether or not with a metallic function, polysulfides, dithionites and sulfoxylates, thiosulfates, thiocarbonates; other inorganic sulfur compounds.' The primary classification criterion for 2830.90 is that the product must be an inorganic sulfur compound that is not specifically provided for in the preceding subheadings of 28.30 (e.g., 2830.10 for sodium sulfides, 2830.20 for zinc sulfide, 2830.30 for cadmium sulfide, 2830.40 for thiocarbonates). Importers must ensure the chemical identity of their product, confirming it is an inorganic sulfur compound, and then systematically rule out all more specific classifications within Heading 28.30 before assigning it to 2830.90. WCO Explanatory Notes for Chapter 28 provide further guidance on the scope of inorganic chemicals.

For chemicals classified under HS 2830.90, standard import documentation includes a commercial invoice, packing list, and bill of lading or air waybill. Crucially, due to the chemical nature of these products, a Safety Data Sheet (SDS) (formerly Material Safety Data Sheet or MSDS) is almost always required by customs authorities and regulatory agencies in the importing country. The SDS provides essential information on the chemical's properties, hazards, and safe handling, which is vital for customs clearance, hazardous materials declarations, and compliance with environmental and safety regulations. Depending on the specific chemical and its end-use, additional permits or licenses from agencies such as the Environmental Protection Agency (EPA) in the U.S. or REACH compliance documentation in the EU may be necessary. Importers should verify specific requirements with the relevant regulatory bodies in the destination country prior to shipment.

Yes, numerous trade agreements can offer preferential duty treatment for products classified under HS 2830.90, provided the products meet the respective agreement's rules of origin. For U.S. importers, agreements like the USMCA (United States-Mexico-Canada Agreement), CAFTA-DR (Dominican Republic-Central America Free Trade Agreement), and various bilateral FTAs (e.g., with Korea, Australia, Singapore) may offer duty-free entry or reduced rates. For EU importers, agreements such as the EU-Japan EPA, EU-Korea FTA, or EU-Mercosur Agreement (if ratified) could provide benefits. Similarly, the UK benefits from its own network of FTAs. To claim preferential treatment, importers must obtain a valid Certificate of Origin or an origin declaration from the exporter, confirming that the goods meet the origin criteria specified in the agreement. It is imperative to review the specific 'Product Specific Rules of Origin' for HS 2830.90 within the applicable trade agreement to ensure compliance.
