Guidance

Report suspicious chemical activity

Report a suspicious transaction, disappearance or theft of regulated or reportable chemicals.

You must tell the Home Office if:

  • 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
  • what chemicals you need to report

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