Singapore’s National Environment Agency will introduce restrictions on chlorpyrifos, medium-chain chlorinated paraffins and long-chain perfluorocarboxylic acids from 16 December 2026. The measures support Singapore’s implementation of international controls on persistent organic pollutants.

The controls cover chlorpyrifos, MCCPs with carbon-chain lengths from C14 to C17 and a chlorination level of at least 45% by weight, and LC-PFCAs with carbon-chain lengths from C9 to C21. Salts and related compounds may also fall within the regulated groups.

Main Restrictions

From the implementation date, the manufacture, import and export of the controlled substances and products containing them will generally be prohibited, subject to applicable exemptions and concentration conditions. Stocks imported or manufactured before the deadline may be depleted locally under the arrangements described by NEA.

Companies should not limit screening to pure substances. MCCPs and LC-PFCAs may be present in mixtures, components or articles, while related compounds may not be identified by the principal acid’s CAS number.

Affected Products and Industries

The controls may affect pesticide products, lubricants, plastic and rubber additives, coatings, sealants, electrical materials and products containing fluorinated substances. Importers and manufacturers should obtain composition and impurity information from suppliers.

Where confidential formulations prevent complete disclosure, companies should obtain a regulatory declaration confirming whether the controlled groups are present. Analytical testing may be appropriate where supplier data are incomplete or inconsistent.

Import and Export Requirements

TradeNet declarations for affected substances and products must use the applicable HS and product codes. Applications will be subject to review by NEA’s Chemical Control and Management Department.

Companies should complete portfolio screening before 16 December and confirm whether any exemption applies. New procurement specifications should prevent affected substances from being introduced after the implementation date.
