Safeguard duty on Phthalic anhydride imposed, limiting imports with specified exemptions and a defined effectiveness period. The Central Government, invoking section 8B(2) of the Customs Tariff Act and relevant safeguard rules, imposed a provisional safeguard duty on imports of Phthalic anhydride under tariff item 2917 35 00 after preliminary findings that increased imports caused and threatened serious injury to domestic producers. The measure excludes imports from developing countries notified under section 8B(6)(a), except Pakistan, Indonesia and Thailand, and is effective until a specified date unless earlier revoked or amended.
