However, as a derogation from the common CU tariff, Kazakhstan will maintain a zero import duty on raw cane sugar up to 2019 with the obligation that neither raw sugar for processing, nor white sugar would be re-directed to Russia or Belarus. For refined sugar, the previous combined duty of 30% (but not less than EUR 120 per tonne) was replaced by a specific duty of EUR 340 per tonne. Tariff rates were increased for many agricultural products and Kazakhstan’s tariff system became less liberal than it had been prior to the CU (Box 2.6). This implies that the CU tariff will evolve in accordance with the commitments that the CU members undertake within the WTO framework.
