Notice by right holder for suspension of clearance of suspected infringing imports under customs enforcement; procedural requirements apply. A right holder may give a notice in writing to the Principal Commissioner of Customs or Commissioner or any authorised customs officer at the port of import requesting suspension of clearance of goods suspected of infringing intellectual property rights; the notice must follow the prescribed Annexure format and be accompanied by a document evidencing payment of the application fee. If required information is missing, the Deputy or Assistant Commissioner may request it within 15 days, which may be extended. The right holder must inform customs if the intellectual property ceases to be valid or ownership changes.
