When goods leave a KEK for the Indonesian domestic market (TLDDP), the import duty and tax exemption ends. Calculation rules mirror Kawasan Berikat: duty is assessed on the value of imported inputs rather than the finished-goods value, recognising local value added.
KEK operators are subject to domestic-sales caps that depend on the KEK type and master licence — typically 50%. Operators producing primarily for the domestic Indonesian market without significant export contribution may have their KEK status reviewed.
