HS 290911 Acyclic ethers and their halogenated, sulphonated, nitrated or nitrosated derivatives

For HS 2909.11, 'Diethyl ether (ethyl ether)', the MFN (Most Favored Nation) import duty rates can vary. For instance, the United States generally applies an MFN duty rate of 4.0% ad valorem. The European Union's TARIC database shows an MFN duty rate of 5.5% ad valorem for many third countries. The UK Global Tariff also lists a 4.0% ad valorem MFN rate. Importers should always consult the specific tariff schedule of the importing country for the most current and accurate MFN rate.

Preferential duty rates, often 'Free' (0% ad valorem), are available under various Free Trade Agreements (FTAs) or Generalized System of Preferences (GSP) programs. For example, in the US, imports 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 qualify for duty-free entry under specific trade agreements, provided all rules of origin requirements are met. Similarly, the EU and UK have extensive preferential arrangements. To claim a preferential rate, importers must typically provide a valid Certificate of Origin (e.g., Form A, EUR.1, or a Free Trade Agreement Certificate of Origin) at the time of import, demonstrating that the goods originate in a beneficiary country according to the specific agreement's rules of origin. Customs brokers can assist in verifying eligibility and preparing the necessary documentation.

HS 2909.11 specifically covers 'Diethyl ether (ethyl ether)'. The primary classification criterion is the chemical identity of the substance. Diethyl ether is a simple acyclic ether with the chemical formula (C2H5)2O. It is distinguished from other acyclic ethers, which are classified in subsequent subheadings of HS 2909 (e.g., 2909.19 for other acyclic ethers), by its specific molecular structure. The 'halogenated, sulphonated, nitrated or nitrosated derivatives' mentioned in the broader heading 2909 also need to be considered; however, 2909.11 is reserved solely for diethyl ether itself, not its derivatives. If the substance is a derivative of diethyl ether that has undergone one of these modifications, it would typically be classified elsewhere, likely within 2909.19 or another more specific heading if applicable. Importers should rely on chemical analysis reports, Safety Data Sheets (SDS), and precise chemical nomenclature to ensure accurate classification, referencing the Harmonized System Explanatory Notes for detailed guidance on distinguishing between various ethers.

Beyond standard import documentation such as the commercial invoice, packing list, and bill of lading/air waybill, the importation of diethyl ether (HS 2909.11) often requires additional chemical-specific documentation due to its properties. Importers should be prepared to provide a Safety Data Sheet (SDS) or Material Safety Data Sheet (MSDS) which details the chemical's properties, hazards, and safe handling procedures. Depending on the country of import and the intended use, permits or licenses from regulatory bodies (e.g., environmental protection agencies, drug enforcement agencies, or chemical control authorities) may be necessary, as diethyl ether can be used as a precursor in certain controlled substances or is subject to specific storage and handling regulations due to its flammability. For claiming preferential duty rates, a valid Certificate of Origin is essential. Customs brokers play a crucial role in identifying all required documentation and ensuring compliance with national chemical import regulations, which can vary significantly by jurisdiction.

Yes, beyond the standard Free Trade Agreements (FTAs) that offer preferential duty rates (e.g., NAFTA/USMCA, EU-Japan EPA, UK-Australia FTA), certain countries may have special programs or duty relief provisions for specific end-uses of chemicals like diethyl ether (HS 2909.11). For example, some jurisdictions offer duty drawback programs for imported goods that are subsequently exported, or for materials used in the manufacture of products that are then exported. Additionally, temporary import regimes may allow for duty-free entry if the diethyl ether is imported for specific purposes such as testing, repair, or exhibition, with the expectation of re-exportation. In some cases, specific industries (e.g., pharmaceuticals, research and development) might qualify for duty exemptions or reduced rates under national industrial promotion policies, provided the importer meets stringent conditions and obtains necessary approvals. Importers should consult with customs authorities or experienced trade compliance specialists to explore all potential duty relief programs applicable to their specific circumstances and end-use of the product.
