19 June 2012 You may evaluate your major portion and whether other services are incidental, like design may be incidental to fabrication.

Then decide your category as advised by experts

25 July 2025 Hey! Here’s a quick rundown to clarify the **service tax registration category** for your client’s activities in mechanical engineering like fabrication, erection, and designing:

---

### 1. **Main Service Category for Fabrication, Erection & Designing**

* The closest and most commonly used **Service Tax classification** is:
**“Erection, Commissioning and Installation Services” (Service Code: 9998)**
This covers erection and installation of plant and machinery, structures, etc.

* For **labour work (contract labour services)** involved, if your client hires labour or provides labour contracting services, the category could be:
**“Labour Contract Services” (Service Code: 9997)**

* For **designing services**, if it is significant and independent, it may fall under:
**“Architectural Services” or “Consulting Engineering Services”**
depending on the nature and scope.

---

### 2. **How to Decide the Service Code?**

* If the **major part of work** is erection and commissioning, register under **Erection, Commissioning and Installation Services**.
* If your client provides labour contract services to others, register separately under **Labour Contract Services**.
* If designing is a separate service (like detailed engineering or consultancy), then register under the appropriate consulting category.

---

### 3. **Where to Find Service Codes & Register?**

* Visit the official ACES portal: [https://www.aces.gov.in/](https://www.aces.gov.in/)
* You can search the **service codes** during registration or amendment under “Service Tax” -> “Registration”.

---

### **Summary Table**

| Activity | Service Tax Category | Service Code |
| ---------------------- | ------------------------------------------------------------------------ | ---------------------------------------------------- |
| Fabrication & Erection | Erection, Commissioning & Installation Service | 9998 |
| Labour Contract Work | Labour Contract Services | 9997 |
| Designing Services | Consulting Engineering Services / Architectural Services (if applicable) | 9986 (Consulting Engineering) / 9987 (Architectural) |

---

### Final Tip

* Choose the service code that best describes the **major part of your client’s business**.
* You can register for multiple services if your client provides more than one service type.

If you want, I can help draft a checklist for registration or even help you with the step-by-step process on ACES.

Does that work for you?
