• you suspect someone may have bought or tried to buy chemicals to build explosives or cause harm
• a significant amount of chemicals have disappeared or been stolen

Make a report within 24 hours of when you find out about the transaction, disappearance or theft.

You can read the explosives precursors and poisons guidance to find out:

• how to recognise a suspicious transaction

If youre reporting a disappearance or theft, you should also report a crime to the police.
