Petron's competitors can turn around immediately and sell the products, while Petron must still process/ refine and that takes about 30 days. Any change in the price of finished products is also reflected weekly at the pump, minimizing inventory loss risk for Petron's competitors. And, Mr. Ang complained, Petron gets taxed more compared to its competitors. Actually, Petron should get a tax break for providing national strategic supply. To be totally dependent on the spot market for finished products puts us in danger of supply disruption because of geopolitics or OPEC decisions. Mr. Ang said he would ask for the same tax treatment as the importers, wherein tax is levied on the final output, not the raw materials, to allow Petron to compete with the importers on an equal footing. Otherwise, RSA said, he would consider closing the refinery, following what Shell recently did.
