Basically, Customs Notices are issued to inform clients about proposed changes to customs procedures. Customs Notice N-15-001 has been published by the Canada Border Services Agency (CBSA) for deleting an obstacle to file import duty refund claims. The Canadian International Trade Tribunal (CITT) has rendered its decision in Appeal No. AP-2012-067, Hudson’s Bay Company v. President of the Canada Border Services Agency, regarding the treatment of rebates made after importation. The CITT governed that a price reduction made after importation is not noticed by the Customs Act if it results from a contract to reduce the price that was in effect during importation. By the transaction value method, the root for a calculation of value for duty is the price paid or payable (PPP) for imported goods. In Customs Act, Paragraph 48(5) (c) addresses descending adjustments to the PPP effected after importation and continues to use in situations where a buyer and seller enter into an agreement to diminish the PPP of goods after those goods have been imported to Canada.
