In cases where a goods supply contract is signed between a Vietnamese entity and a foreign contractor under DDU or DAP delivery terms, where the seller is responsible for transporting the goods to the delivery location designated by the buyer, and the contract does not include any services provided in Vietnam (such as installation, trial run, warranty, maintenance, etc., including cases where these services are provided free of charge), the contract is subject only to value-added tax (VAT) on goods at the importation stage and a corporate income tax (CIT) rate of 1% on taxable revenue.
