Report Duty Evasion

The CBSA is committed to working with importers and any other stakeholder to ensure compliance with payment of anti-dumping and countervailing duties. If you have information or tips relating to suspected fraud or the non-payment of duties and would like to provide this to the CBSA, please fill the anonymous form below.
