Generally halal
E407 (Carrageenan) is a gelling and thickening agent extracted from red seaweed — a plant source — so it is generally considered halal.
Carrageenan is a family of carbohydrates extracted from certain red seaweeds. It is used to thicken, gel and stabilise foods, and is one of the common plant-based alternatives to gelatine for texture.
Extracted from red seaweed (e.g. Kappaphycus, Eucheuma, Chondrus) by alkaline treatment, then filtered and dried. No animal-derived material.
Because carrageenan comes from seaweed and no animal-derived processing material is normally involved, it is generally classified as halal. As always, the finished product still needs its own verification.
It may be found in — this does not mean every product below contains it.

Yes — it is extracted from red seaweed, a plant source, so it is generally considered halal. The finished product still needs its own verification.
No. Gelatine is animal-derived; carrageenan is a plant (seaweed) gelling agent and is often used as a halal alternative.

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.
