Generally halal
E132 (Indigo Carmine / Indigotine) is a synthetic blue dye — despite the name 'carmine' it is not made from insects — so it is generally treated as halal at the ingredient level.
Indigo Carmine, also called Indigotine, is a synthetic blue colouring. The word 'carmine' in its name causes confusion, but unlike carmine E120 it is not derived from insects — it is manufactured chemically.
Made by chemical synthesis (sulfonation of synthetic indigo). No animal-derived raw materials in the standard process.
Indigo Carmine is generally classified as halal at the ingredient level because it is fully synthetic, with no animal or alcohol component — the 'carmine' in the name refers to the colour, not to insect cochineal (E120). The finished product still requires its own verification.
It may be found in — this does not mean every product below contains it.

Humble Halal methodology: we classify additives by their common origin, not by any specific product. A generally-halal ingredient does not make a finished product halal-certified.
