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.
                        Most are classified under GIR #1
40.11    New pneumatic tires, of rubber 
a)         of a heading text 
          40.11             tires
          84.13             pumps
          84.82             ball bearings
          85.32             capacitors
b)  of a legal note:
          Section XVI note 1(h): drill pipe (heading 73.04)
B.  Parts of general use as defined in Section XV, Note 2
                        *This is an application of GIR #1
73.18    Screws, bolts, nuts, etc.
Second Category


PARTS OF GENERAL USE”, as defined in Section XV, Note 2:
Throughout the Nomenclature, the expression “parts of general use” means:
a)      Articles of heading 73.07,73.12,73.15,73.17 or 73.18 and similar articles of other base metal;
b)      Springs and leaves for spring, of base metal 73.20, other than clock or watch springs (91.14); and
c)      Articles of headings 83.01,83.02,83.08,83.10 and frames and mirrors, of base metal, of heading 83.06.
         73.18   STEEL WASHERS
         73.12   STEEL CABLES
         83.08   BUCKLES OF BASE METALS
-Articles of other base metals go to other chapters of Section XV
    e.g. copper cables     74.13
           aluminum nails   76.16
Section XVI  Note 1: Similar articles of plastics go to Chapter 39
   e.g., plastic screws                39.26
C.        Parts suitable for use solely or principally with a particular kind of machine or with machines or the same heading
            *This is an application of GIR# 1
             Applies to parts outlined in:
            Section XVI, Note 2 (b)
            Section XVII, Note 3
            Chapter 90 Note 2 (b)
         A)        in the same heading:
                        84.06               steam turbines and other
                                                vapor turbines
                        8406.90-          parts
                                                (I.E. rotors, stators; rotor or stator blades)
         B)        in a specific heading:

General Rules of Interpretation – Customs Tariff – Harmonized System


The GRI’s instruct users to a single classification number that is appropriate for each  product – they explain how to classify.
There are 6 GRI’s, and they must be applied systematically in order.


GRI rule 1
If a commodity is specifically named in a heading, you must use that heading in order to classify your good.   
         GRI 1 has precedence
         Rules 2 through 4 apply ONLY if goods cannot be classified by the application of GRI 1


GRI rule 2(a)
Use rule 2(a) to classify incomplete/unfinished and unassembled/disassembled goods.
They must have the essential character of the complete or finished article. E.g.
“Blanks” are considered an article not ready for direct use, having the approximate shape or outline of the finished article or part, and which can be used only for completion into the finished article or part.


GRI rule 2(b)
The classification of goods consisting of more than one material or substance shall be according to the principles of Rule 3.
Therefore, if you have a mixture or combination immediately go to GRI 3.
An example of when to apply GRI 2(b) would be Grass Seed of heading 12.09 that was treated with a fast grow fertilizer.


GRI rule 3
Resolves the potential for classification disputes or gridlock when you have a commodity that can be classified under two or more headings of the HS. By applying the principles governing GRI 3 the matter can be resolved in three ways – by:
            3 (a)  Employing the most specific description
            3 (b)  Classifying according to essential character
            3 (c)  Using the last heading in numerical order


The criteria must be applied in the order presented


GRI rule 3(a) – more specific heading
         Applied to goods which are not multifunctional nor composed of more than one material or substance, when the goods are classifiable under two or more headings
         Gives priority to the heading with the more/most specific description
Example – classification of electric shavers
85.09         Electro-mechanical domestic appliances, with self-contained motor
85.10                  Shavers and hair clippers, with self-contained electric motors
85.10 would be correct as the most specific.


GRI Rule 3(b) – Essential Character
Applied if:
    1. More than one heading could apply
    2. The headings are equally specific; and
    3. The goods are:
         a mixture,
         composed of different materials,
         made up of different components, or
         presented in sets put up for retail sale.
Essential character is subjective. It may be based on, for example:
         the nature of the material or components
         their volume, quantity, weight, quality, & value
         their relative importance with regard to end use
        Legal notes
Example – Where would you classify a Pre-packaged spaghetti dinner if it consisted of the following?
         A package of uncooked spaghetti (heading 19.02)
         A pouch of grated cheese (heading 04.06)
         And a can of tomato sauce (heading 21.03)
Answer: The essential character of Pre-packaged spaghetti dinner would be derived from the package of uncooked spaghetti, of heading 19.02
Exception to GRI 3(b) – Gift baskets or boxes that contain a variety of products.
If any one of these commodities falls under the TRQ regime, such as: cheese or cheese products, wheat or barley products, GRI 3(b) will not apply, and every product identified in the basket or box will have to be rated & classified under their own respective headings. 
*A common mistake is to assume a set must be classified using essential character, GRI 3(b), however, some sets are provided for in the terms of the heading and therefore GRI 1 would apply.
Example : Tariff item 8206.00   Provides for Tools put up in sets for retail sale
Example : Tariff item 8215.20.10 provides for “Other sets of assorted articles


GRI Rule 3(c) – Last Heading
When goods cannot be classified by reference to Rule 3 (a) or 3 (b), they shall be classified under the heading which occurs last in numerical order among those which equally merit consideration.
         Applied when classification cannot be resolved by GRI 3(a) or 3(b)
         Simply gives priority to the heading
last in numerical order
         Reflects the general structure of the Nomenclature (i.e., advancing complexity)
GRI 3(c) Example
An axe and saw are packaged together as a set for retail sale.
82.01   … axes …
                            8201.40 – Axes … and similar hewing                                                                   tools
82.02   Hand saws…..
                            8202.10 – Hand saws…
         Headings are equally specific
         Neither provides set its essential character
         Classified under heading 82.02 – last in numerical order


GRI Rule 4
Goods which cannot be classified in accordance with GRI 1, GRI 2(a) & (b), GRI 3(a), (b) or [c], shall be classified under the heading appropriate to the goods to which they are Most akin, (Similar to)
  • Applied only if rules 1 to 3 cannot not resolve the classification
  • The goods are not provided for anywhere else in the Nomenclature, including any of the residual headings.
  • Very rarely used; if ever
  • If ever used, would be based on a comparison to similar goods, taking into account factors such as:
            description       character       purpose
  • Exists only to ensure the GRI’s are exhaustive
    (i.e., that even something never before known or considered could be classified)


GRI Rule 5
In addition to the foregoing provisions, the following Rules shall apply in respect of the goods referred to therein:
(a) Camera cases, musical instrument cases, gun cases, drawing instrument cases, necklace cases and similar containers, specially shaped or fitted to contain a specific article or set of articles, suitable for long-term use and presented with the articles for which they are intended, shall be classified with such articles when of a kind normally sold therewith.  This Rule does not, however, apply to containers which give the whole its essential character.


GRI Rule 5(a)
This rule applies to Cases / Containers
         specially shaped or fitted for the article
         suitable for long-term use
         presented with the article; and
         of a kind normally sold therewith that do not themselves give the whole its essential character.


GRI Rule 5(b)
(b) Subject to the provisions of Rule 5 (a), packing materials and packing containers presented with the goods therein shall be classified with the goods if they are of a kind normally used for packing such goods.  However, this provision is not binding when such packing materials or packing containers are clearly suitable for repetitive use.
Covers packing materials and containers:
         Presented with goods
         Of a kind normally used for packing such goods
         Not suitable for repetitive use
Examples –
ü      Collar and backing inserts in men’s shirts
ü      Plastic bags containing chips, candies, etc.
      X   Liquefied gas container filled with gas (Suitable for repetitive use)


GRI Rule 6
All the preceding rules apply to the Sub-Heading Level.
