GST@ 12% ON JOBWORK AGAINST 20/2019- Central Tax (Rate)

Dear All,

We are doing job work activities to aviation customers for the Mfr of Rubber product & Metal Product. Now we charged GST @ 18%. and Using SAC Code 9988 [ (ii) Manufacturing services on physical inputs (goods) owned by others, other than (i) above.]

As per Not.No. 20/2019- Central Tax (Rate), GST rate will be change @ 12%.

Kindly suggest us, can we implement GST @ 12 % for further job work activities for rubber product and metal product ?

Thanks
