AI Summary

Effluent treatment services classification as taxable cleaning services may attract service tax; verify central excise overlap.
Whether charges for onsite cleaning and chemical filtration of process effluent returned for reuse constitute taxable cleaning services as notified with effect from 16.6.2005, and whether the activity falls within the domain of central excise thus affecting service tax liability; no specific exemption or special environmental concession is indicated in the record.
