Chapter 38: Miscellaneous chemical products

Plain-language overview

Use HS-4 3825 when importing residual products from the chemical or allied industries, such as municipal waste or sewage sludge. For example, if you're handling a shipment of treated sewage sludge for disposal, this heading is relevant.

When deciding between the HS-6 lines, consider the specific type of waste. For instance, 382510 covers municipal waste broadly, while 382520 is specific to sewage sludge. If your waste includes clinical materials, you would use 382530 instead.

If your shipment consists of organic solvents, you need to distinguish between halogenated and non-halogenated types. Use 382541 for halogenated waste organic solvents and 382549 for other waste organic solvents.

For waste types not specifically categorized, such as metal pickling liquors or hydraulic fluids, refer to 382550. If your waste is primarily organic but doesn't fit into the other categories, consider 382561.
