Practical Classification Guidance

Where the main focus of a contract is routine housekeeping, exterior façade cleaning or tank desilting rather than sterilization of operating rooms, a different SAC from the 99853 group should be selected. Matching the SAC to the core activity makes GST classification easier to defend during audits.

Conclusion

Sterilization of operating rooms is a critical hygiene service for hospitals and clinics, and falls in the standard 18% GST slab in most cases. Using the correct SAC, agreeing the scope of work in writing and keeping simple documentation around each visit helps both the healthcare provider and the vendor stay ready for GST scrutiny.
