Technical Grade
F tier
Technical-grade ammonium bicarbonate is a fertilizer, fire-extinguisher, or chemical intermediate salt. It is not a food. Purity, residual metals, and microbiology are not specified for a cookie. Do not bake with it because it is cheaper or because the crystal looks the same. This variety exists in the catalogue so a buyer can see the grade they must refuse. Food-grade powder is the only kitchen form. A sack labelled "technical" or "industrial" belongs in a plant room, not a dough trough.

History
Industrial ammonium bicarbonate served agriculture and chemistry beside the smaller food stream.
Grade separation on labels became essential as the same salt moved in food and technical sacks.
Food-contact rules made technical-grade use in bakeries an obvious non-compliance.
Online chemical vendors still required a clear "not for food" distinction from baker's ammonia.
