What is the HSN Code for Fabrication Services?
Fabrication means cutting, bending, welding and assembling different parts to make a new structure or product. In many businesses fabrication is done as a job work service on goods owned by the customer. Under GST such fabrication activities are normally treated as service and are covered under specific service accounting codes which work similar to HSN codes for goods.
Examples include metal fabrication of industrial parts, sheet metal fabrication for enclosures and frames, and structural fabrication for buildings and machinery. The correct code depends on whether the fabricator is supplying only the service on customer material or is also supplying the finished fabricated goods from his own material.

Classification of Metal and Sheet Metal Fabrication under HSN
Where a fabricator receives raw material from the customer and returns the fabricated item, the activity is usually covered under the service code for manufacturing services on physical inputs owned by others. This applies to cutting, bending, punching and welding carried out on metal plates, sections, tubes and similar inputs.
If the fabricator buys metal on his own account and supplies fabricated structures such as beams, columns, frames or platforms, the supply is treated as goods. In such cases the classification generally shifts to the chapter that covers structures and parts of structures of iron or steel or other relevant commodity chapter. The tax invoice must clearly state whether it is a goods supply or service supply.

Understanding Fabrication Services under GST
For GST, fabrication services are taxable in the state where the service is performed or where the contract places the supply. If the activity qualifies as job work, then special provisions relating to job work may apply for movement of goods and time limits for return of processed goods.
Fabricators should maintain job work registers, delivery challans and proper documentation of raw material received and finished goods sent back. This ensures that there is no confusion during departmental verification and that principal manufacturers are able to claim full input tax credit on fabrication charges.
Importance of Correct Fabrication HSN Code for Taxation
Using the correct fabrication service code is important because the rate of tax, place of supply and eligibility of input tax credit may depend on the classification. Wrong classification can lead to short payment of tax, interest liability and denial of input tax credit to the recipient.
Businesses engaged in fabrication should study the description of service codes in detail, consider advance rulings issued for similar activities and, where necessary, take professional advice. Correct classification helps in accurate pricing, smoother GST return filing and fewer disputes in the long run.
