Comparing costs across Brazilian ports means keeping the same model and shipping conditions, the fees and clearance arrangements at each port, and the inland transport to the target market in a single versioned record, so no one argues from different documents. When choosing a port, compare port charges, clearance and inland transport for the same model and shipping week; the total can differ even when the vehicle price is unchanged. Before handover, confirm that the same model and shipping conditions have been logged and the fees and clearance arrangements at each port are backed by documentation; if the inland transport to the target market changes, both parties confirm again. When finished, have the person responsible for Brazil car landed costs sign off, record the date of the documents used, and note any exceptions that must be cleared before the next step.
No port is universally 'cheaper'; any comparison must use the same model, sailing time window and delivery location.

The comparison is ultimately governed by the local rules and written confirmations in force at the time of processing.
