HS Code for Hexachlorobenzene mixtures

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.

Products Included

• Chemical mixtures containing hexachlorobenzene
• Industrial waste containing HCB
• Contaminated soil containing hexachlorobenzene
• Solvent blends containing pentachlorobenzene or HCB
• Non-retail chemical preparations with HCB as an additive

Common Misclassification

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.

FAQ

What is the HS code for waste containing hexachlorobenzene?

Waste or mixtures containing hexachlorobenzene are classified under HS code 3824.86, as this subheading specifically covers preparations containing this substance.

When should I use 2903.92 instead of 3824.86?

Use 2903.92 only for the pure, separate chemically defined compound. If the substance is mixed with any other chemicals or is part of a waste stream, 3824.86 is the correct code.
