Dear Heng,
if you want Commercial Invoice and Packing lists to be revised and show supplier from India as a seller, then supplier from India has to issue mentioned Commercial Invoice and Packing list. He also needs to indicate "FOR CUSTOMS CLEARANCE PURPOSES ONLY". Please confirm that to Ravi, he is freight forwarder on behalf of Rockwool India. Please confirm if I understood correctly.
Dear Ravi (supplier's freight forwarder), please work with Heng and see what he needs to be done from Rockwool's side in the order to complete this.
