How to Classify This HS Code?
What products does HS 293060 cover?
This subheading covers 2-(N,N-Diethylamino)ethanethiol, a specific organo-sulphur compound defined by its chemical structure. As per the Harmonized System Nomenclature, specifically Chapter 29, this product is a distinct chemical entity falling under Heading 2930, which encompasses organo-sulphur compounds. The official USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both precisely delineate this subheading for this singular chemical, ensuring consistent global classification for this particular ethanethiol derivative, which is characterized by the presence of both a thiol (-SH) group and a diethylamino group.
What falls outside HS 293060?
The following products are excluded from HS 293060: other ethanethiols that lack the N,N-diethylamino substituent, such as ethanethiol (ethyl mercaptan) itself, which would typically fall under a different subheading within Heading 2930 or even outside it if not an organo-sulphur compound. Similarly, compounds where the diethylamino group is present but the sulphur is not in a thiol form, or where the base carbon chain is different, would also be excluded. For instance, diethylamine (HS 2921.19) or other sulphur-containing compounds like sulphides or disulphides without the specific 2-(N,N-diethylamino)ethanethiol structure are not covered here.
What are common classification mistakes for HS 293060?
A common error is misclassifying similar-sounding or structurally related organo-sulphur compounds under HS 293060, failing to strictly adhere to the chemical specificity of "2-(N,N-Diethylamino)ethanethiol." Importers might incorrectly classify other aminoethanethiols or diethylamino derivatives if they do not precisely match the full chemical name and structure. This often stems from a lack of detailed chemical analysis or an over-reliance on trade names rather than the systematic nomenclature. Adherence to General Interpretative Rule (GRI) 1, which dictates classification by the terms of the headings and any relative section or chapter notes, is crucial to avoid such errors, ensuring the exact chemical identity is confirmed.
How should importers classify products under HS 293060?
The correct procedure for classifying products under HS 293060 involves a meticulous review of the product's chemical name, CAS number, and structural formula to confirm it is precisely "2-(N,N-Diethylamino)ethanethiol." Importers and customs brokers should obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) from the manufacturer, which clearly states the chemical identity. Cross-referencing this information with the WCO Harmonized System Explanatory Notes for Chapter 29 and Heading 2930, alongside the specific national tariff schedules (e.g., USITC HTS or EU TARIC), will ensure accuracy. If any doubt exists, seeking a binding tariff information (BTI) ruling from the relevant customs authority is highly recommended to prevent costly misclassification penalties.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS code 293060, '2-(N,N-Diethylamino)ethanethiol'?
The MFN (Most Favored Nation) import duty rate for HS code 293060, '2-(N,N-Diethylamino)ethanethiol', typically ranges from 3.7% to 6.5% ad valorem in many developed markets. For example, the United States generally applies a 6.5% ad valorem duty rate under the Harmonized Tariff Schedule of the United States (HTSUS) for goods from non-preferential countries. Importers should consult the specific tariff schedule of the importing country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff) for the precise and current MFN rate applicable at the time of importation.
Are there any preferential duty rates available for '2-(N,N-Diethylamino)ethanethiol' under HS 293060, and which trade agreements apply?
Yes, preferential duty rates, including 'Free' (0% ad valorem), are available for '2-(N,N-Diethylamino)ethanethiol' when originating from countries with which the importing nation has a Free Trade Agreement (FTA) or other preferential trade programs. For instance, in the U.S., goods classified under HS 293060 may qualify for duty-free entry if originating 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) under their respective FTAs. Importers must ensure the goods meet the specific Rules of Origin criteria of the applicable trade agreement and provide proper documentation, such as a Certificate of Origin, to claim preferential treatment.
What are the key classification criteria for '2-(N,N-Diethylamino)ethanethiol' under HS 293060, and why is it not classified elsewhere?
HS code 293060 specifically covers 'Compounds containing an atom of sulfur exclusively as a hetero-atom and those whose structure contains one or more other non-metals (e.g., nitrogen, oxygen) in addition to carbon and hydrogen atoms.' '2-(N,N-Diethylamino)ethanethiol' is a thioether (a compound containing a sulfur atom bonded to two alkyl or aryl groups) and also contains a nitrogen atom (from the diethylamino group), making it a complex organic chemical. It is classified here because Chapter 29 covers organic chemicals, and heading 2930 is for organo-sulfur compounds. The '60' subheading specifically captures acyclic thioethers and their halogenated, sulfonated, nitrated, or nitrosated derivatives. Its specific chemical structure, featuring both sulfur and nitrogen hetero-atoms, places it precisely within this subheading, distinguishing it from simpler thiols (e.g., 2930.90) or other nitrogen-containing compounds without sulfur (e.g., Chapter 29, Subchapter X).
What documentation is typically required for importing '2-(N,N-Diethylamino)ethanethiol' under HS 293060?
Standard import documentation for '2-(N,N-Diethylamino)ethanethiol' under HS 293060 includes a commercial invoice, packing list, bill of lading or air waybill, and potentially a customs declaration form specific to the importing country. Due to its chemical nature, a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) is almost always required by customs and regulatory agencies to assess potential hazards and ensure compliance with chemical control regulations (e.g., TSCA in the U.S., REACH in the EU). If claiming preferential duty rates, a valid Certificate of Origin (e.g., NAFTA/USMCA Certificate, EUR.1, or other FTA-specific certificate) is mandatory. Importers should also be prepared for potential scrutiny regarding end-use, especially if the chemical has dual-use potential, and may need to provide end-user statements or import permits.
Are there any specific import restrictions or additional duties (e.g., Section 301) that might apply to HS 293060?
While HS 293060 itself does not inherently carry widespread specific restrictions beyond standard chemical regulations, importers must be aware of potential additional duties or import restrictions based on the country of origin. For example, goods originating from certain countries, such as China, may be subject to additional tariffs under trade remedy measures like Section 301 duties in the United States. These additional duties, which can be significant (e.g., 25% ad valorem), are applied on top of the standard MFN or preferential rates. Importers should verify the current status of such tariffs against the specific country of origin using official tariff resources (e.g., USTR website for Section 301 lists) to avoid unexpected costs. Furthermore, some chemicals may be subject to export controls in the country of origin or import controls in the destination country if they are considered precursors for controlled substances or have dual-use applications.
