Authorities have imposed an automatic price freeze on basic goods in Oriental Mindoro and Romblon provinces following the declaration of a state of calamity after Typhoon Opong battered Luzon and Visayas regions, officials said Wednesday.

The freeze, which took effect immediately after the September 29, 2025 calamity declaration, covers nine categories of basic necessities including canned fish, processed milk, instant noodles and bottled water, the Department of Trade and Industry (DTI) for the MIMAROPA region announced.

The measure will remain in force for the duration of the calamity but cannot exceed 60 days, under Republic Act 7581, known as the Price Act.

The law, amended by RA 10623, empowers the government to impose price controls during declared states of calamity to prevent traders from exploiting emergency situations.

Other items covered by the freeze include marine products, coffee, laundry soap, candles, bread, and iodized salt.

The DTI warned that violators face “severe legal consequences” and urged consumers to report any instances of overpricing to its offices.

The Philippines’ Price Act mandates an automatic price freeze on basic necessities and prime commodities when a state of calamity is declared by local or national authorities.

The freeze applies immediately upon declaration without need for additional government action, protecting consumers when their purchasing power may be compromised by disasters.

Basic necessities under DTI jurisdiction include food staples, household supplies and hygiene products deemed essential for daily living.

The Department of Agriculture separately enforces price controls on agricultural products including rice, corn, vegetables, meat and fish during calamities.

Violators can face imprisonment of up to 10 years and fines ranging from P5,000 to P2 million pesos or both, depending on the gravity of the offense.
