Yes you can use the services of a customs broker to transport cargo.
When you need to import or export cargo across countries then having a good customs broker who knows what they are doing can save you a lot of trouble.
When you're exporting and importing cargo you have to go through customs which can be trouble if you're not sure how to exactly do it.
But if you hire someone who works as a customs broker and knows exactly what they are doing then it can save you a lot of time and frustration while you work more on the business of getting that cargo shipped.
