The extension was approved under a new government resolution issued this week.
The tax cut was first introduced under Decree No. 72 dated March 9, 2026, which lowered preferential import tariffs on selected petroleum products and fuel-production inputs to zero through April 30.
Under the new resolution, the policy will remain in effect for an additional two months.
Products subject to the zero tariff include certain petroleum feedstocks and fuel-production materials such as partly refined crude oil and intermediate petroleum products.
From July 1, preferential import tax rates on fuel and related inputs will revert to levels stipulated under Decree No. 26/2023, the government said.
The Ministry of Finance said the extension was intended to help stabilise the domestic fuel market and ensure energy security amid continued global uncertainty.
The measure is also aimed at supporting macroeconomic stability and helping maintain economic growth targets, the ministry added.
