Structural steel erection services, including steel construction works and steel structure erection, are treated as works contract or civil engineering services under GST. Earlier, different combinations of steel supply and erection sometimes produced different effective tax outcomes for similar projects, which created uncertainty for contractors and industrial clients.
After the September 2025 rationalisation, most structural steel erection services under SAC 995455 generally come under the 18 percent slab with
input tax credit
. This standard rate applies where structural steel is fabricated and erected as part of a works contract, unless a specific notification gives concessional treatment for a particular strategic or public scheme.
The table below explains the current GST rate applicable to SAC code 995455 services.
