Production route
The specific technology path used to make a good (e.g. BF-BOF vs EAF for steel). CBAM default values and attribution rules depend on it.
Production route is a required field in the Commission communication template. For steel: BF-BOF (blast furnace / basic oxygen furnace) vs EAF (electric arc furnace). For aluminium: primary smelting vs secondary (recycled). The route determines which emission sources are relevant and which default values apply.
