gst on almirah and cooler

As per chapter 73 under iron & steel under18% ""All goods not specified elsewhere"" So, Steel almirah is not written anywhere under iron & steel , as a result we can say any other good made up of iron & steel not specified elsewhere is taxable under 18%.. Also from Sales Tax Deptt (unofficially ) it is suggested them it to be 18% (it is not 101% confirm, still 1-2% confusion) thanks (REST PLS CONFIRM FROM YOUR ADVISOR)
