Canadian Interpretive rules

Canadian Interpretive Rules – Customs Tariff – Harmonized Code


  1. All the above GRI’s apply to the Tariff Item Level.
  2. Where both a Canadian term and an international term are presented, the international term shall take precedence.
  3. For the purpose of GRI rule 5(b), packing material clearly suitable for repetitive use is to be classified separately. 
Classifying Parts and Accessories
The Harmonized system does not define “Part” or “Accessory”
However the tariff classification unit in Ottawa has developed a policy on classifying parts and accessories
It is outlined in Customs Memorandum D10-0-1 as follows:
…a Part is defined as “an identifiable component of an article, machine, apparatus, equipment, appliance or specific good which is integral to the design & essential to  the function of the product in which it is used.”
…an Accessory is an Article which performs a secondary or subordinate role, not essential to the function, which could improve the effectiveness of the host machine, equipment, apparatus or appliance.


         Articles (parts & accessories) specifically named in a heading or provided for in the tariff.  If provided for, the good should be classified in its respective tariff item.
         When the part is not specifically named or provided for in the tariff, and is for use solely or principally with an article, it is to be classified with that article.


Classification of Parts
Parts are classified into 4 distinct categories
A.         Articles (parts & accessories) specifically named in a heading.
