That EWC code isn't one Defra recognises

Defra checks every waste code against the official List of Wastes, and this one is not on it.

What to do

1. Press Correct the record.
2. Pick the waste code again from the list in Tipslip.
3. Press Save correction and re-submit.

Tipslip sends the corrected record to Defra as soon as you save.
