When is a toxics permit required, and how do you start?

Who this applies to

Anyone who holds, produces, transports, sells or uses substances classified as hazardous — plants, laboratories, logistics warehouses, print shops, garages and treatment facilities. Small quantities can also come into scope, because the carve-outs are not only quantitative.

What it means in practice

• The exemption is not a default: it applies only to what the regulations define, in the quantities and on the conditions they define.
• Regulation 3 can bring back a permit obligation for an activity that looks exempt under regulation 2. This is the provision most businesses miss.
• The 2024 reform does not sweep the previous regime away — it replaces it for activities listed in the Third Schedule and preserves it for the rest.
• A substance's classification follows its safety data sheet and its official classification, not its trade name.
• A check finding that these particular regulations do not bring you into a permit obligation does not establish that no other obligation applies — business licensing, environmental protection, fire safety and contractual undertakings are separate regimes.

What is usually needed

• The actual list of substances, with official name and classification — not trade names alone.
• Current safety data sheets (SDS) for every substance.
• The maximum quantities held at any one time, rather than annual consumption.
• A description of the activity: holding, producing, using, storing or transporting — each means something different.
• Site details and the storage conditions as they actually are.

Common mistakes

• Reading regulation 2 and stopping. The exemption is read together with its carve-out, or the answer comes out backwards.
• Calculating from annual consumption instead of the quantity held at one time.
• Relying on a substance's trade name instead of the classification on its safety data sheet.
• Assuming the 2024 reform removed the need. For some activities it changed nothing.
• Reading "no obligation was found within this check" as "there is no obligation".
