What to do if your ozone-depleting substances (ODS) exports are rejected at an EU border control post (BCP).

The National Clearance Hub (NCH) and the Environment Agency will check and decide how to deal with your ODS. If you have any questions, contact

If your ODS meets clearance processes, you can place it on the market in Great Britain.

You may need to destroy the ODS if it is banned or does not comply with clearance process.
