HS Code for Pentachlorobenzene mixtures

Pentachlorobenzene mixtures are classified under HS code 3824.86. This classification follows the logic of Chapter 38, which encompasses miscellaneous chemical products. Unlike pure chemicals found in Chapter 29, heading 3824 is designed for chemical products and preparations that are not elsewhere specified or included. Subheading 3824.86 specifically covers mixtures containing pentachlorobenzene (ISO) or hexachlorobenzene (ISO). This classification is mandated by Note 3 to Chapter 38, which directs that mixtures containing certain persistent organic pollutants (POPs) must be classified in subheadings 3824.81 through 3824.89. The Harmonized System prioritizes these specific subheadings to ensure that hazardous mixtures are tracked accurately across international borders. Even if the mixture contains other active or inactive ingredients, the presence of pentachlorobenzene as a regulated component forces the classification into this specific 3824.86 category, provided the mixture is not better described by a more specific heading like 3808 for pesticides.

Products Included

• Industrial mixtures containing pentachlorobenzene
• Waste streams containing detectable levels of pentachlorobenzene
• Chemical preparations where pentachlorobenzene is a secondary component
• Solvent mixtures containing hexachlorobenzene or pentachlorobenzene

Common Misclassification

The most common misclassification is placing these mixtures under HS code 2903.93. Code 2903.93 is strictly for the separate chemically defined compound. If the product is a mixture of multiple chemicals, it must move to Chapter 38. Additionally, if the mixture is specifically formulated as a pesticide, it might be misclassified here instead of heading 3808, though 3824.86 often takes precedence for POP-containing mixtures depending on the specific national tariff notes.

FAQ

What is the HS code for Pentachlorobenzene mixtures?

The HS code for mixtures containing pentachlorobenzene is 3824.86, located within the miscellaneous chemical products chapter.

Why are these mixtures not classified in Chapter 29?

Chapter 29 is reserved for separate chemically defined compounds. Once a substance is mixed with other chemicals for industrial use or as a byproduct, it generally moves to Chapter 38.
