HS code for Hexachlorobenzene mixtures: 3824.86

Chemical products, mixtures and preparations, containing goods specified in Subheading Note 3 to this Chapter, containing pentachlorobenzene (ISO) or hexachlorobenzene (ISO).

Classification of hexachlorobenzene mixtures under HS 3824.86

Hexachlorobenzene mixtures are classified under HS code 3824.86. This code falls under Chapter 38, which covers miscellaneous chemical products. Heading 3824 is for prepared binders for foundry moulds or cores; chemical products and preparations of the chemical or allied industries not elsewhere specified. Subheading 3824.86 specifically addresses mixtures containing pentachlorobenzene or hexachlorobenzene. Unlike the pure chemical, these are preparations where HCB is a component. This classification is often used for industrial waste, contaminated soil, or specific chemical blends regulated under international environmental conventions like the Stockholm Convention. The Harmonized System distinguishes between pure chemicals (Chapter 29) and mixtures (Chapter 38). If hexachlorobenzene is mixed with other substances, even if it is the active or primary ingredient, it generally moves to Chapter 38 unless it is a formulated pesticide ready for retail sale. Subheading 3824.86 was introduced to provide a specific category for products containing these hazardous substances, allowing customs authorities to track the movement of persistent organic pollutants. This includes waste streams containing HCB and chemical preparations where HCB is used as a stabilizer or intermediate in a non-pure form.

  • Arcadis (hazardous waste management)
  • specialized chemical suppliers for analytical standards

Codes often confused with 3824.86

Common mistake. The most common misclassification is placing these mixtures under 2903.92, which is reserved for pure hexachlorobenzene. Another error involves formulated pesticides; if the mixture is a finished insecticide or fungicide containing HCB, it should be classified under heading 3808. Additionally, mixtures containing other halogenated hydrocarbons might be incorrectly placed in 3824.99 (other chemical products) instead of the specific 3824.86 category for HCB.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
