ARGO Calgary Customs Brokers: Apparel samples have to be classified under a dual classification system. Importers are required to keep a signed statement on file certifying the qualifying use of an eligible apparel sample and are thereby deemed to have specified the use of the apparel sample at the time of reporting the goods under the Customs Act. In the case of a company, an authorized signing officer must sign the written statement. Clients are to keep a copy of this record on file for the period of six years following the importation of the commercial goods and be prepared to present it to the Canada Border Services Agency (CBSA) when requested to do so.
