As checked with shipper, they have their own customs brokerage to arrange export customs clearance.
They are not allowed us to arrange it & will debit us for this charge instead.
Due to our policy cannot allow other customs broker arrange customs process & bill us in case term of delivery is ex-work.
Pls check with customer if term of delivery can be changed to be FCA Factory or FCA Bangkok instead.
Then we’ll inform shipper to use their own customs broker as their request.
