HS 290393 Pentachlorobenzene (ISO)
Quick Answer: HS code 290393 specifically covers Pentachlorobenzene (ISO), a chlorinated aromatic hydrocarbon. This chemical is primarily used as an intermediate in the synthesis of other organic compounds, particularly in the production of pesticides, dyes, and flame retardants, though its use has declined due to environmental concerns. Importers and exporters should be aware of varying duty rates: the EU applies a 5.50% ad valorem duty, while the UK imposes 4.00%. In the US, the Most Favored Nation (MFN) rate is 5.5%, with preferential duty-free access available under various Free Trade Agreements (e.g., A+, AU, BH, CL). Additionally, specific US duty provisions can include a compound rate of 15.4¢/kg + 71%. Due to its environmental profile, trade in Pentachlorobenzene may be subject to import/export restrictions or licensing requirements under international conventions like the Stockholm Convention on Persistent Organic Pollutants.

How to Classify This HS Code?
What products does HS 290393 cover?
This subheading covers Pentachlorobenzene (ISO), a specific chlorinated derivative of benzene. According to the Harmonized System Nomenclature, as interpreted by the World Customs Organization (WCO), and reflected in national tariffs like the USITC Harmonized Tariff Schedule (HTSUS) and the EU TARIC, this code is precisely for the chemical compound with the molecular formula C6HCl5. It is an aromatic halogenated hydrocarbon, specifically a benzene ring with five chlorine atoms attached. This classification is reserved for the pure chemical substance, distinguishing it from mixtures or preparations where pentachlorobenzene might be present but not as the primary constituent or in a form that alters its fundamental character.
What falls outside HS 290393?
The following products are excluded from HS 290393: other chlorinated benzenes, such as hexachlorobenzene (HS 290399) or trichlorobenzenes (HS 290399), which are distinct chemical compounds despite their structural similarity. Furthermore, mixtures or preparations containing pentachlorobenzene, where it is not the sole or principal constituent, would typically be classified elsewhere, often under Chapter 38 if they are preparations not elsewhere specified or included, or under other headings based on their primary function or composition. For instance, a pesticide formulation containing pentachlorobenzene as an active ingredient would likely fall under Chapter 38, specifically heading 3808, rather than this chemical-specific heading.
What are common classification mistakes for HS 290393?
A common error is misclassifying other chlorinated benzenes, such as hexachlorobenzene or various isomers of trichlorobenzene, under HS 290393 due to their similar chemical nature. Importers sometimes overlook the precise "penta" prefix, leading to incorrect assignments. Another frequent mistake involves classifying mixtures or formulations containing pentachlorobenzene here, rather than under headings for preparations (e.g., Chapter 38), which is a misapplication of General Interpretative Rule (GRI) 3(b) concerning mixtures. Accurate classification requires strict adherence to the chemical name and ensuring the product is indeed the pure, isolated chemical compound specified.
How should importers classify products under HS 290393?
The correct procedure for classifying products under HS 290393 involves verifying the exact chemical identity of the substance. Importers and customs brokers must obtain a Certificate of Analysis (CoA) or Safety Data Sheet (SDS) to confirm the product is unequivocally Pentachlorobenzene (ISO) with the chemical formula C6HCl5. This ensures compliance with the specific nomenclature of Heading 2903 and subheading 290393. If the product is a mixture or preparation, even if pentachlorobenzene is present, further analysis under GRI 3 is necessary to determine the appropriate heading, which will likely be outside 290393, potentially in Chapter 38 or another functional heading.

FAQ
What are the standard Most Favored Nation (MFN) import duty rates for Pentachlorobenzene (HS 290393) in major economies?
The MFN duty rates for Pentachlorobenzene (HS 2903.93) vary by importing country. For instance, the United States applies a duty rate of 4.0% ad valorem under the Harmonized Tariff Schedule of the United States (HTSUS). The European Union's TARIC database indicates a standard MFN duty rate of 5.5% ad valorem. The UK Global Tariff also lists a 5.5% ad valorem MFN duty rate. Importers should always consult the specific tariff schedule of the destination country for the most current and accurate MFN rates.
Are there any preferential duty programs or free trade agreements that offer reduced or zero duties for HS 290393?
Yes, many preferential trade agreements and programs offer reduced or zero duties for Pentachlorobenzene (HS 2903.93) when originating from eligible countries. For example, under the HTSUS, imports from countries designated as A+, AU, BH, CL, CO, D, E, IL, JO, K, KR, MA, OM, P, PA, PE, S, and SG may be eligible for 'Free' duty rates, subject to meeting the specific Rules of Origin for the respective agreement (e.g., USMCA, KORUS FTA, CAFTA-DR, etc.). Importers must ensure they have the necessary documentation, such as a Certificate of Origin, to claim these preferential rates. Always verify the specific agreement's requirements and the product's origin.
What are the key classification criteria for Pentachlorobenzene under HS 2903.93, and what distinguishes it from similar chemicals?
HS 2903.93 specifically covers 'Pentachlorobenzene (ISO)'. The classification criteria hinge on the precise chemical identity and structure. Chapter 29 of the Harmonized System covers organic chemicals of known chemical definition. Subheading 2903 covers halogenated derivatives of hydrocarbons. The '93' sub-heading is reserved for Pentachlorobenzene (ISO) within the 'Other' category of halogenated derivatives. It is crucial that the product is chemically pure Pentachlorobenzene (C6HCl5) as defined by ISO. Importers must ensure that the chemical name, CAS number (608-93-5), and chemical structure on the Safety Data Sheet (SDS) or Certificate of Analysis (CoA) precisely match the definition to avoid misclassification. Products that are mixtures or derivatives other than pure Pentachlorobenzene would be classified elsewhere, potentially under other subheadings of 2903 or other chapters depending on their composition and function.
What specific documentation is typically required by customs authorities for importing Pentachlorobenzene (HS 2903.93)?
For importing Pentachlorobenzene (HS 2903.93), standard customs documentation includes a Commercial Invoice, Packing List, Bill of Lading or Air Waybill, and a Certificate of Origin (if claiming preferential duty rates). Due to the nature of chemical products, a Safety Data Sheet (SDS) and/or Certificate of Analysis (CoA) are often requested by customs to verify the chemical identity, purity, and safety characteristics. Depending on the importing country's regulations, additional permits or licenses from environmental or chemical control agencies may be necessary, especially if the substance is subject to specific chemical control regimes (e.g., POPs regulations, REACH in the EU). Importers should proactively check with the relevant national authorities for any such specific requirements prior to shipment.
