thank you!
I think i am seeing the same one as you (US SDS, UK SDS) as i didnt find any SDS specific for NZ
it doesn't state H411 or H412 warning. it just says "Please read Section 2 completely. If any environmental warnings such as; H411 or H412 are listed in Section 2, please use appropriate procedures when disposing of product and container. Do not put materials into waterways or sewers."
I thought that meant, do not dispose of underglazes in waterways or sewers, regardless of H411 or H412 being present or not
