Attock Refinery Limited (ARL) has announced a temporary shutdown of its main crude distillation unit (HBU-I) for three to four days starting January 4, 2026, due to low crude stocks and high product inventories at the refinery.
In a notice to the Pakistan Stock Exchange, ARL stated that the reduced upliftment of premium motor gasoline (PMG) and high-speed diesel (HSD) by oil marketing companies (OMCs) during December 2025 led to an accumulation of product stocks, necessitating the shutdown.
The HBU-I unit has a capacity of 32,400 barrels per stream day (BPSD).
During the shutdown, ARL will carry out essential maintenance activities. The company emphasized that other crude units and downstream process units will remain operational, and committed volumes and uninterrupted dispatches for the current month will be ensured.
The company has communicated the development to the Securities and Exchange Commission of Pakistan and assured stakeholders that the shutdown is temporary and part of routine operational management.
