The Philippine Department of Environment and Natural Resources (DENR) has added 81 chemicals to the Philippine Inventory of Chemicals and Chemical Substances (PICCS). The additions were issued through DENR Administrative Order No. 2026-24, signed on 11 May 2026 and published on 15 July 2026. The Order takes effect on 30 July 2026, 15 days after its publication and filing with the Office of the National Administrative Register. It was issued under Republic Act No. 6969, the Toxic Substances and Hazardous and Nuclear Wastes Control Act of 1990, its implementing rules under DENR Administrative Order No. 29 of 1992, and Section 5 of DAO 2025-09.
DAO 2026-24 updates the PICCS with 81 substances that completed the applicable new-chemical process. The Order covers chemicals imported or manufactured with an issued Pre-Manufacture, Pre-Importation Notification (PMPIN) Compliance Certificate and a submitted Notice of Commencement. A Notice of Commencement is filed after the first commercial importation or manufacture of a new chemical. Once included in PICCS, a substance is treated as an existing chemical rather than a new chemical for Philippine inventory purposes. The additions include organic chemicals, inorganic compounds, polymers, reaction products, fatty-acid derivatives, lubricating oils, fragrance ingredients, dyes, surfactant-related substances and specialty additives.
The change is relevant to chemical manufacturers, importers, formulators, distributors and downstream users operating in the Philippines. From 30 July 2026, companies intending to import or manufacture one of the 81 listed substances should be able to rely on its PICCS inventory status when conducting new-chemical screening. Companies should verify the substance identity against both the chemical name and CAS number recorded in the Order, particularly for polymers, reaction products and substances of variable or complex composition. PICCS listing does not automatically exempt a chemical from other Philippine controls. Companies should continue screening listed substances against the Priority Chemicals List, Chemical Control Orders, hazardous-substance requirements and any sector-specific import, use, reporting, labelling or environmental obligations.
The DENR states that the additional list will be released annually. Updated inventory information will also be made available through the Environmental Management Bureau’s chemical management website and the Online Permitting and Monitoring System. Companies maintaining Philippine chemical inventories should update their internal records from the effective date and retain evidence supporting the identity and PICCS status of relevant substances.
