Colombian auto dealers should agree in advance on a written approval process for specification changes in the contract. Purchasing should list critical parameters that may not be substituted without approval, the change-notice deadline, approvers, and the remedy for unapproved changes, and require the supplier to link final specifications to VINs. Conduct a final pre-shipment review against the approved version. Destination-country market access, registration, and declaration requirements are subject to the relevant authorities, licensed institutions, and applicable contractual terms.
