HS Code 3825Residual products of the chemical or allied industries, not elsewhere specified or included; municipal waste; sewage sludge; other residual products.

What HS code 3825 covers

Think of this heading as the place for residues. Factories, cities and hospitals all create waste that is not a planned product. When that waste has no heading of its own, it ends up here. Some traders search for it as HSN code 3825. It is the same code.

The letters n.e.c. mean not elsewhere specified or included. If another heading names your goods, use that heading. Use 3825 only for what is left over.

The name sounds vague, but the subheadings are clear. They sort goods by type of waste: city waste, sludge, hospital waste, used solvents, spent fluids and everything else.

HS 3825 subcodes in plain words

The legal text for each subcode is long and starts with the same words every time. Here is the short version, so you can find your line fast.

• 382510: municipal waste
• 382520: sewage sludge
• 382530: clinical waste
• 382541: halogenated waste organic solvents
• 382549: waste organic solvents other than halogenated
• 382550: wastes of metal pickling liquors, hydraulic fluids, brake fluids and anti-freeze fluids
• 382561: other wastes in this heading, mainly containing organic constituents
• 382569: other wastes in this heading, except those mainly containing organic constituents
• 382590: other residual products not named above

How to pick the right 3825 subcode

Start with the type of waste. Household and city waste has one line. Sludge from sewage treatment has another. Waste from hospitals and clinics has a third. Do not mix them up.

For used solvents, ask one question: is the solvent halogenated? A lab report or safety data sheet usually answers this. The answer decides between 382541 and 382549.

For other wastes, check what the material is mostly made of. Mostly organic material goes to 382561. Anything else goes to 382569. Spent pickling liquors and used hydraulic, brake or anti-freeze fluids have their own line, 382550.

Choose 382590 last. It is for residual products that no other line fits. Duty and import rules differ by country, so check the national tariff of the importing country. The HS code classifier can also help you test a description.

• 3824: prepared binders for foundry moulds, and chemical products and preparations not named elsewhere
• 3814: organic composite solvents and thinners, and prepared paint or varnish removers
• 3819: hydraulic brake fluids and other prepared liquids for hydraulic transmission
• 3820: anti-freezing preparations and prepared de-icing fluids
• 3826: biodiesel and mixtures of it
