HS 290399 Other
Quick Answer: HS 2903.99, "Other," is a residual classification within Chapter 29 for acyclic halogenated derivatives of hydrocarbons not elsewhere specified. This code covers a diverse range of organic chemicals, including various fluorinated, chlorinated, brominated, or iodinated acyclic compounds. Due to its "other" nature, specific product identification is crucial for accurate classification at the national subheading level. Duty rates vary significantly. The UK Trade Tariff shows rates like 0.00% and 4.00% ad valorem across its 19 subheadings. The EU TARIC also presents a range, including 0.00% and 5.50% ad valorem for its 19 subheadings. The US Harmonized Tariff Schedule (HTS) includes rates such as 5.5% ad valorem, "Free" under various preferential trade programs (e.g., A+, AU, CL), and even compound rates like 15.4¢/kg + 71% for specific products. Importers and customs brokers must verify the precise 8-digit (or 10-digit for US) subheading to determine the applicable duty and any trade program eligibility.

How to Classify This HS Code?
What products does HS 290399 cover?
This subheading covers acyclic halogenated derivatives of hydrocarbons not elsewhere specified or included within Heading 2903. Specifically, it acts as a residual category for compounds that are acyclic, contain one or more halogen atoms (fluorine, chlorine, bromine, iodine), and are not specifically provided for in subheadings 2903.11 through 2903.92. This includes a diverse range of organic chemicals, such as certain brominated or iodinated alkanes and alkenes, or mixed halogenated derivatives, as defined by the World Customs Organization's Harmonized System Explanatory Notes and reflected in the USITC Harmonized Tariff Schedule and EU TARIC.
What falls outside HS 290399?
The following products are excluded from HS 290399: saturated chlorinated derivatives of acyclic hydrocarbons (e.g., dichloromethane, chloroform, carbon tetrachloride) which are classified under 2903.12, 2903.13, and 2903.14 respectively. Unsaturated chlorinated derivatives, such as trichloroethylene and tetrachloroethylene, fall under 2903.22 and 2903.23. Fluorinated, brominated, or iodinated derivatives specifically provided for in other subheadings of 2903 are also excluded. For instance, bromomethane is classified under 2903.39, and certain fluorinated derivatives are found in 2903.41 through 2903.49, ensuring precise classification based on the specific halogen and saturation.
What are common classification mistakes for HS 290399?
A common error is to prematurely classify a halogenated acyclic hydrocarbon under 290399 without first exhaustively checking the more specific subheadings within Heading 2903. Importers often overlook the detailed breakdowns for saturated chlorinated, unsaturated chlorinated, or specific fluorinated, brominated, and iodinated compounds. This can lead to misclassification if, for example, a compound like 1-bromo-3-chloropropane, which is a mixed halogenated derivative, is incorrectly placed here instead of a more specific residual category if one existed, or if a compound specifically named elsewhere is overlooked. Adherence to General Interpretative Rule (GRI) 1, which prioritizes specific descriptions, is crucial.
How should importers classify products under HS 290399?
The correct procedure for classifying products under HS 290399 involves a systematic review of the chemical structure. Importers and customs brokers must first confirm the compound is an acyclic halogenated derivative of a hydrocarbon. Next, they must meticulously check all other subheadings within Heading 2903 (2903.11 through 2903.92) to ensure the product is not more specifically described elsewhere based on the type of halogen, degree of saturation, and specific chemical name. Only if the compound is definitively not covered by any other more specific subheading should it be classified under the residual subheading 290399, ensuring compliance with the WCO's hierarchical classification principles and national tariff schedules.

FAQ
What is the Most Favored Nation (MFN) import duty rate for products classified under HS 290399 in key markets?
The MFN (Most Favored Nation) import duty rates for HS 290399 'Other halogenated derivatives of hydrocarbons' vary significantly by importing country. For instance, the United States generally applies a 4.0% ad valorem duty rate for MFN countries (Source: USITC HTSUS, Chapter 29). The European Union's TARIC database indicates a common MFN duty rate of 5.5% ad valorem. The UK Global Tariff also lists a 5.5% ad valorem MFN rate. Importers should always verify the current rate for their specific destination country using official tariff databases.
Which preferential trade agreements offer duty-free or reduced rates for goods under HS 290399?
Many preferential trade agreements provide duty-free or reduced rates for products classified under HS 290399, provided the goods meet the respective rules of origin. For imports into the United States, duty-free treatment (indicated as 'Free') is available under agreements such as the USMCA (Canada, Mexico), CAFTA-DR (D), various FTAs with 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). Similar preferential rates exist for the EU and UK under their respective agreements. Importers should consult the specific trade agreement's rules of origin and provide the necessary documentation (e.g., certificate of origin) to claim preferential treatment.
What are the key classification criteria for products falling under HS 290399, 'Other halogenated derivatives of hydrocarbons'?
HS 290399 is a residual 'Other' subheading within heading 2903, which covers 'Halogenated derivatives of hydrocarbons'. Classification under 290399 applies to halogenated derivatives that are not specifically provided for in subheadings 290311 through 290394. This includes, but is not limited to, certain mixed halogenated derivatives (e.g., chlorobromomethanes, chloroiodomethanes) or other complex halogenated hydrocarbons that do not fit more specific descriptions. The primary criterion is the chemical structure: the presence of halogen atoms (fluorine, chlorine, bromine, iodine) attached to a hydrocarbon skeleton, and the absence of other functional groups that would place them in a different chapter (e.g., alcohols, ethers, aldehydes). Importers should refer to the Explanatory Notes to the Harmonized System for Chapter 29 and heading 2903 for detailed guidance.
Are there any specific documentation requirements or regulatory considerations for importing chemicals under HS 290399?
Beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), importers of chemicals under HS 290399 may face additional regulatory requirements depending on the specific chemical compound and the importing country. For example, in the United States, certain chemicals may be subject to regulations by the Environmental Protection Agency (EPA) under the Toxic Substances Control Act (TSCA), requiring TSCA certification. The EU's REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation may require pre-registration or registration for substances imported in certain quantities. Safety Data Sheets (SDS) are almost universally required for chemical imports to ensure safe handling and provide hazard information. Customs brokers and importers must verify national chemical control laws and obtain any necessary permits or certifications prior to import.
