Packing material code you need to check as FG of supplier. HSN code of supplier will be final in transaction.

I packed a Almirah used various type of packing material in packing of almirah  like bubble roll (GST 18%), corrugated roll (GST 12), plastic sutli (GST 18%), paper katran (GST 12%), adhesive tape (GST 18%) 

Almirah  1 pc  12000

gst 28%            3360

Add Paking Material (all packing material items used)  1000
