The increase was achieved through the transport of iron-ore and oil from Russia to Uzbekistan, grains from Russia to Iran and Uzbekistan, polyvinyl chloride from China to Uzbekistan, fertilizers from Russia to Turkmenistan, China, and Kyrgyzstan, ferrous metals from Russia and China to Central Asia, machinery and equipment from China to Uzbekistan and Poland, from Poland to China and from Korea to Uzbekistan, and sugar from Russia and Ukraine to Uzbekistan. KTZ Freight is also delivering regular shipments of tomato paste from China to Italy and grain from Kazakhstan to Turkey. By the end of 2018, KTZ Cargo had organised 4367 container trains, 54% more than 2017. The launch of the Kuryk ferry complex and the Baku - Tbilisi - Kars line gave additional importance to traffic along the Trans-Caspian international freight corridor, which provided a direct connection to the southern and western ports of Turkey and access to the Mediterranean.
