Is 19 12 12 hazardous?

No. It’s the non-hazardous half of a pair with 19 12 11*. GOV.UK says you must assess waste from mechanical treatment to find out whether it has hazardous properties: if it does, it’s 19 12 11*. If what’s in it genuinely can’t be found out, it’s 19 12 11* too.

What goes under 19 12 12?

Mixed waste that comes out of sorting, crushing, compacting or other mechanical treatment at a waste site: the residue a transfer station or MRF can’t sort any further, and fines from screening.

Materials sorted into a single stream take their own code, such as 19 12 02 for ferrous metal or 19 12 04 for plastic. GOV.UK says those codes are only for single streams: a load with more than one type of waste in it is mixed, so it’s 19 12 12 or 19 12 11*. Chapter 19 codes

Are trommel fines 19 12 12, 19 12 11* or 19 12 09?

GOV.UK names trommel fines from screening construction and demolition waste as a mixed waste from mechanical treatment. They usually hold soil, aggregate, plastic, wood and metal. So they’re 19 12 12, or 19 12 11* if an assessment finds them hazardous.

19 12 09: Only for natural minerals such as sand and stone. GOV.UK says it mustn’t include bricks, concrete, tiles or ash.
17 05 04: Not for fines. SEPA says fines aren’t soil.

Write what the fines came from on the note, such as “fines from processing mixed C&D waste”. SEPA says “fines” on its own isn’t enough.
