HS Code for PCT mixtures

HS code 3824.82 is specifically designated for chemical products and preparations containing polychlorinated biphenyls (PCBs), polychlorinated terphenyls (PCTs), or polybrominated biphenyls (PBBs). This classification is part of a global effort to monitor and control persistent organic pollutants (POPs) as mandated by the Stockholm and Basel Conventions. These mixtures are classified here because they contain specific hazardous substances listed in Subheading Note 3 to Chapter 38. Historically, these chemicals were used in industrial applications for their excellent dielectric properties and thermal stability. However, due to their environmental toxicity, they are now strictly regulated. The classification applies to mixtures where these substances are present as intentional ingredients or significant contaminants. Customs authorities use this code to ensure that hazardous waste or restricted industrial chemicals are handled according to international safety protocols. The code covers both unused chemical preparations and waste products containing these specific halogenated compounds, provided they are not classified more specifically elsewhere in the tariff.

Products Included

• Dielectric fluids containing PCTs
• Hydraulic fluids containing polychlorinated biphenyls
• Heat transfer fluids with PBB content
• Lubricating preparations containing PCBs
• Waste oils containing polychlorinated terphenyls

Common Misclassification

This code is often confused with 2710.91, which covers waste oils containing PCBs or PCTs. The distinction lies in whether the product is a primary chemical preparation (3824.82) or a waste petroleum oil (2710.91). It is also sometimes confused with 3824.99, the residual category for other chemical products, but 3824.82 takes precedence due to the specific mention of the hazardous substances in the subheading notes.

FAQ

What is the HS code for PCT mixtures?

The HS code for chemical mixtures containing polychlorinated terphenyls (PCTs) is 3824.82.

Why is 3824.82 used for environmental monitoring?

It allows customs and environmental agencies to track the movement of hazardous persistent organic pollutants across borders to ensure compliance with international treaties.
