The odour scale, while useful, is still semi-subjective. For food-contact applications, safety is governed by EFSA and FDA migration limits, not odour. TG5 explicitly avoids food safety, which is the domain of other regulations. This can create confusion: a TG5 Grade A material may be clean but still illegal for food use. Iso 20457 Tg5
