On 20 August 2025, ITAC initiated a sunset review of anti-dumping duties imposed on boards, sheets, panels, tiles, and similar articles of plaster or compositions based on plaster, not ornamented, faced or reinforced with paper or paperboard only, not ornamented (gypsum plasterboard), classifiable under tariff subheading 6809.11, originating in or imported from Thailand and Indonesia.
The application for this review was lodged by Saint-Gobain Construction Products South Africa (Pty) Ltd and supported by Etex South Africa Building Systems (Pty) Ltd. The applicant had argued that expiry of the duties would likely lead to renewed dumping, with prima facie evidence showing dumping margins of 22.26% (Thailand) and 41.74% (Indonesia), and that recurrence of injury would result in price suppression, price depression, and undercutting.
This investigation will determine whether the current anti-dumping duties should remain in force or be terminated upon completion.
