HS 292143 Toluidines and their derivatives; salts thereof
Quick Answer: HS code 2921.43 covers Toluidines and their derivatives, along with their respective salts. These are organic chemical compounds, specifically aromatic amines, primarily used as intermediates in the production of dyes, pigments, pharmaceuticals, and rubber chemicals. Importers and exporters should be aware of varying duty rates and specific product classifications within this heading. For instance, the UK Trade Tariff shows rates such as 6.00% ad valorem, with some subheadings at 0.00%. The EU TARIC indicates rates like 6.50% ad valorem. The US Harmonized Tariff Schedule presents more complex rates, including 15.4¢/kg + 60% ad valorem, and some "Free" rates, depending on the specific chemical and country of origin. Due to the diverse applications and chemical structures, precise classification at the 8-digit or 10-digit level is crucial to determine the correct duty and any applicable regulatory requirements.

How to Classify This HS Code?
What products does HS 292143 cover?
This subheading covers toluidines and their derivatives, as well as their respective salts. Toluidines are a group of three isomeric organic compounds: o-toluidine (2-methylaniline), m-toluidine (3-methylaniline), and p-toluidine (4-methylaniline). These are aromatic amines derived from toluene, where an amino group (-NH2) replaces a hydrogen atom on the benzene ring. The WCO Harmonized System Explanatory Notes for Heading 2921 confirm the inclusion of these specific isomers and their derivatives, provided they retain the essential chemical characteristics of toluidines. Official tariff schedules, such as the USITC Harmonized Tariff Schedule of the United States (HTSUS) and the EU TARIC, align with this definition, encompassing the pure compounds and their chemically modified forms that maintain the toluidine structure.
What falls outside HS 292143?
The following products are excluded from HS 292143: products that are not specifically toluidines or their direct derivatives, or their salts. For instance, other aromatic monoamines like aniline (HS 2921.42) or xylidines (HS 2921.49) are explicitly classified elsewhere, despite their structural similarities to toluidines. Furthermore, complex derivatives where the toluidine structure is significantly altered or incorporated into a larger, more specific chemical compound, such as certain dyes or pharmaceutical intermediates, may be classified under more specific headings within Chapter 29 or even Chapter 32 (Dyeing extracts; Tannins and their derivatives; Dyes, pigments and other colouring matter; Paints and varnishes; Putty and other mastics; Inks) if they function primarily as such. Products that are mixtures containing toluidines but are not predominantly toluidines or their derivatives might also be excluded, depending on the nature of the mixture and the application of General Interpretative Rule 3.
What are common classification mistakes for HS 292143?
A common error is misclassifying other aromatic amines as toluidines, particularly xylidines or even aniline, due to their similar chemical structures and uses. Importers might incorrectly assume that any methyl-substituted aniline falls under "toluidines," overlooking the precise definition that limits toluidines to the mono-methylanilines. Another frequent mistake involves derivatives that have undergone further chemical modification, leading to a product that is more specifically described by another subheading. For example, a toluidine derivative used as a specific dye intermediate might be incorrectly placed here instead of a more specific subheading under Heading 2921 or even Chapter 32, if its primary function has shifted. Adherence to General Interpretative Rule 1, which dictates classification by the terms of the headings and any relative section or chapter notes, is crucial to avoid such errors.
How should importers classify products under HS 292143?
The correct procedure for classifying products under HS 292143 involves a meticulous review of the product's chemical name, CAS number, and molecular structure to confirm it is indeed a toluidine, a direct derivative thereof, or a salt of these compounds. Importers and customs brokers should first consult the WCO Harmonized System Explanatory Notes for Heading 2921 to understand the scope and exclusions. Subsequently, cross-referencing with national tariff schedules, such as the USITC HTSUS or the EU TARIC, is essential to confirm the specific subheading. If the product is a derivative, ensure it retains the essential character of a toluidine. For any ambiguity, obtaining a chemical analysis report or a binding tariff information (BTI) ruling from the relevant customs authority (e.g., CBP in the US, HMRC in the UK) is highly recommended to ensure accurate and compliant classification, mitigating potential penalties or delays.

FAQ
What is the Most Favored Nation (MFN) import duty rate for HS 2921.43 'Toluidines and their derivatives; salts thereof' in key markets?
The MFN import duty rates for HS 2921.43 vary by importing country. For example, the United States imposes a duty rate of 6.5% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS) for goods originating from non-preferential countries. The European Union's TARIC database indicates a conventional duty rate of 6.5% ad valorem. The United Kingdom Global Tariff (UKGT) also applies a 6.5% ad valorem rate. Importers should always verify the current rates directly with the respective customs authority (e.g., USITC, EU TARIC, UK Trade Tariff) as rates can be subject to change.
Are there any preferential duty rates available for 'Toluidines and their derivatives; salts thereof' under HS 2921.43 through free trade agreements or special programs?
Yes, preferential duty rates, including duty-free treatment, may be available for HS 2921.43 depending on the country of origin and applicable trade agreements. For instance, under the United States-Mexico-Canada Agreement (USMCA), goods originating from Mexico or Canada are typically eligible for duty-free entry into the U.S. (0.00% ad valorem), provided all rules of origin are met. Similarly, the EU offers preferential rates under various agreements such as those with South Korea or Japan. Importers should consult the specific trade agreement's rules of origin and ensure proper documentation, such as a certificate of origin, is prepared to claim preferential treatment. Failure to meet origin requirements will result in the application of the MFN rate.
What are the key classification criteria for products under HS 2921.43, specifically 'Toluidines and their derivatives; salts thereof'?
HS 2921.43 specifically covers 'Toluidines and their derivatives; salts thereof'. The primary classification criteria revolve around the chemical identity of the substance. Toluidines are isomers of methylaniline, meaning they are aromatic amines containing a methyl group and an amino group attached to a benzene ring. Derivatives include chemically modified versions of toluidines, provided they retain the essential character of a toluidine. Salts of these compounds are also included. Importers must ensure that the chemical name, CAS number, and molecular structure on commercial invoices and technical data sheets precisely match the description for this subheading. Misclassification can occur if the substance is a different type of aromatic amine or a more complex derivative that falls under another subheading within Chapter 29, 'Organic chemicals'.
What specific documentation is required for importing goods classified under HS 2921.43?
Standard import documentation is required for HS 2921.43, including a commercial invoice, packing list, bill of lading or air waybill, and potentially a customs declaration form. For chemical products like toluidines, additional documentation is often critical. This includes a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) to provide information on the chemical's properties, hazards, and safe handling. A Certificate of Analysis (CoA) may also be required to confirm the chemical composition, purity, and specifications. If claiming preferential duty rates under a free trade agreement, a valid Certificate of Origin or origin declaration is mandatory. Importers should also be aware of any national chemical control regulations (e.g., TSCA in the U.S., REACH in the EU) that may require pre-market notification or registration.
