As I informed you in our last email, at this point, it is not the right time for us to revise invoice as we have already declared export customs based on our current invoice.
Also, I think you could still declare customs based on the invoice as details in the packing list of the goods are only the accessories for the main items described in the invoice.
for composite goods made up of different components in order to define HS code for the goods.
Your understanding is highly appreciated!
