HS 290892 4,6-Dinitro-o-cresol (DNOC (ISO)) and its salts
Quick Answer: HS code 290892 specifically covers 4,6-Dinitro-o-cresol, commonly known as DNOC (ISO), and its chemical salts. DNOC is an organic compound primarily used as a pesticide, particularly as an insecticide, herbicide, and fungicide, though its use has been restricted or banned in many regions due to environmental and health concerns. For importers and exporters, understanding the specific duty rates is crucial. In the UK, the general Most Favoured Nation (MFN) duty rate is 4.00%. The EU applies an MFN rate of 5.50%. For the US, the MFN rate is 5.5%, with additional preferential duty-free access available under various trade agreements (e.g., A+, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG). However, a higher Column 2 duty rate of 15.4¢/kg + 48.5% applies to goods from non-MFN countries. Importers should verify product eligibility for preferential treatment and be aware of any import restrictions or prohibitions related to DNOC due to its hazardous nature.

How to Classify This HS Code?
What products does HS 290892 cover?
This subheading covers specifically 4,6-Dinitro-o-cresol, commonly known by its ISO common name DNOC, and its various salts. According to the Harmonized System Nomenclature Explanatory Notes for Heading 2908, this heading encompasses halogenated, sulphonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols. Subheading 290892 precisely isolates DNOC and its salts from other nitrated derivatives. The USITC Harmonized Tariff Schedule (HTS) and the EU TARIC system both align with this WCO definition, ensuring consistent global classification for this specific chemical compound, which is primarily used as an insecticide, herbicide, and ovicide.
What falls outside HS 290892?
The following products are excluded from HS 290892: other nitrated derivatives of phenols or phenol-alcohols, even if structurally similar, which would fall under other subheadings of 2908, such as 290899. For instance, dinitrophenols other than 4,6-Dinitro-o-cresol, or mononitrophenols, would be classified elsewhere within Heading 2908. Furthermore, mixtures containing DNOC but formulated as preparations for use as insecticides, herbicides, or similar purposes, where the DNOC is not the sole or principal active ingredient, would typically be classified in Chapter 38, specifically under headings like 3808, due to their prepared nature and intended application, rather than as a pure chemical compound.
What are common classification mistakes for HS 290892?
A common error is misclassifying other dinitrophenols or their salts under HS 290892, failing to recognize the specificity of "4,6-Dinitro-o-cresol (DNOC (ISO)) and its salts." Importers might incorrectly assume that any dinitrophenol derivative belongs here, overlooking the precise isomer and common name specified. Another mistake involves classifying prepared formulations containing DNOC as the pure chemical compound. According to General Interpretative Rule (GRI) 3(b), mixtures and composite goods are classified by the material or component which gives them their essential character. If DNOC is part of an agricultural preparation, it should be classified in Chapter 38, not as a pure chemical in Chapter 29, which is reserved for separate chemically defined organic compounds.
How should importers classify products under HS 290892?
The correct procedure for classifying products under HS 290892 involves a meticulous review of the chemical's identity and purity. Importers and customs brokers must first confirm through chemical analysis or supplier documentation that the product is precisely 4,6-Dinitro-o-cresol or one of its salts, matching the ISO common name DNOC. Secondly, verify that the product is a separate chemically defined organic compound and not a prepared formulation or mixture intended for specific end-uses, which would typically fall under Chapter 38. Consulting the WCO Harmonized System Explanatory Notes for Heading 2908 and obtaining a binding tariff information (BTI) decision from the relevant customs authority (e.g., US Customs and Border Protection or EU national customs) is highly recommended to ensure accurate and legally compliant classification.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for HS code 2908.92 in key markets?
The MFN import duty rates for HS 2908.92, which covers '4,6-Dinitro-o-cresol (DNOC (ISO)) and its salts,' vary by importing country. For example, the United States applies a general MFN duty rate of 4.0% ad valorem. The European Union's TARIC database indicates a standard MFN duty rate of 5.5% ad valorem. The United Kingdom Global Tariff also lists a 5.5% ad valorem rate. Importers should always consult the specific tariff schedule of the destination country for the most current and accurate MFN rates, as these are subject to change based on national trade policy and WCO recommendations.
Are there any preferential duty rates available for HS 2908.92 under common trade agreements?
Yes, preferential duty rates are often available for HS 2908.92 depending on the country of origin and the trade agreements in force with the importing country. For instance, in the United States, imports of 4,6-Dinitro-o-cresol and its salts may be eligible for duty-free treatment under various Free Trade Agreements (FTAs) or special preference programs. Examples of countries whose originating goods might qualify for duty-free entry (indicated by 'Free' or specific program indicators like A+, AU, BH, CL, CO, D, E, IL, JO, KR, MA, OM, P, PA, PE, S, SG in some tariff schedules) include Australia, Bahrain, Chile, Colombia, Israel, Jordan, Korea (Republic of), Morocco, Oman, Panama, Peru, and Singapore, among others. Importers must ensure they meet all rules of origin and provide proper documentation (e.g., a certificate of origin) to claim preferential treatment. Consult the specific FTA text and the importing country's customs regulations for detailed requirements.
What are the key classification criteria for HS 2908.92, and what are common misclassification risks?
HS 2908.92 specifically covers '4,6-Dinitro-o-cresol (DNOC (ISO)) and its salts.' The primary classification criterion is the precise chemical identity of the substance. It falls under Chapter 29 of the Harmonized System, which covers 'Organic chemicals,' and more specifically under subheading 2908, for 'Halogenated, sulphonated, nitrated or nitrosated derivatives of phenols or phenol-alcohols.' The '92' sub-heading precisely identifies DNOC and its salts. Common misclassification risks include confusing DNOC with other nitrated phenols or their derivatives that might fall under different subheadings within 2908 (e.g., 2908.99 for 'Other'). Importers must ensure that the chemical name, CAS number, and chemical structure precisely match the description for 4,6-Dinitro-o-cresol or its salts to avoid misclassification. A Certificate of Analysis (CoA) from the manufacturer is crucial supporting documentation.
Are there any specific documentation requirements or regulatory considerations for importing HS 2908.92, given its chemical nature?
Yes, beyond standard customs documentation (commercial invoice, packing list, bill of lading/air waybill), importing HS 2908.92 may involve additional regulatory requirements due to its chemical properties. As a dinitrocresol, DNOC is known to be toxic and has historically been used as a pesticide. Therefore, importers should anticipate potential scrutiny and requirements related to chemical control regulations. This could include:
- Safety Data Sheets (SDS): A current SDS is essential, providing information on hazards, safe handling, and emergency procedures.
- Chemical Registration/Notification: Depending on the importing country, there may be requirements for registration or notification under chemical inventory laws (e.g., TSCA in the US, REACH in the EU, K-REACH in Korea).
- Pesticide/Hazardous Substance Regulations: If the substance is intended for use as a pesticide or falls under hazardous substance classifications, additional permits, licenses, or declarations from environmental protection agencies or agricultural ministries may be required.
- Import Licenses: Some countries may require specific import licenses for certain chemicals. Importers should verify all national and international regulations applicable to hazardous chemicals and pesticides prior to shipment.
