Gris how to classify


HS general rules of interpretation (GRIs) 

Use these classification rules for maximum accuracy.

Classifying goods can be extremely difficult and subjective and largely depends on the details provided for an item. When classifying, it’s critical to follow the six General rules of interpretation (GRIs). These rules are applied sequentially to ensure uniformity and consistency when assigning HS codes to a product.

This document will review the six GRI rules that should be applied every time an item is classified.

Rule one: Terms of the headings, section/chapter notes 

“The titles of Sections, Chapters, and sub‑Chapters are provided for ease of reference only; for legal purposes, Classification shall be determined according to the terms of the headings and any relative section or chapter notes.” -World Custom’s Organizations' GRI

If a product’s details clearly describe a product that matches the HS schedule, it should be classified accordingly. For example, if you’re classifying dried grapes, it should clearly be classified under heading 0806, “grapes, fresh or dried.”

Rule two: Unassembled or disassembled goods 

Any reference in a heading to an article shall be taken to include a reference to that article incomplete or unfinished, provided that, as entered, the incomplete or unfinished article has the essential character of the complete or finished article.

If a product is unassembled or disassembled, it should be classified in the same heading as the assembled article. For example, a shipment of an unassembled bicycle containing all parts necessary to build the bicycle would be classified in heading 8712, “bicycles and other cycles, not motorized.”

Rule three: Two or more headings 

When goods are classifiable under two or more headings, classifications shall be effected by 3(a): the most specific heading, 3(b): goods consisting of different materials or components or sets shall be classified by the product’s main essential character, and 3(c): last in numerical order.

For example, while rubber yoga and kitchen mats are very similar, they have different classifications based on rule 3(a), the most specific heading. Yoga mats are classified in chapter 9506, “articles and equipment for general exercise,” while kitchen mats are classified based on rule 3(b), essential character, because there is not a specific heading for kitchen mats, in 4016, “articles of rubber.”

If an item can’t be classified in reference to GRI 3(a) or 3(b), then you’d simply default to the last in numerical order according to 3(c). Rule 3(c) is for use in cases in which a good seems to fit in more than one heading and the essential character cannot be determined. For example, “metal figurine” could be classified in heading 9503, “children’s toy,” or in 8306, “ornamental art,” so it’d be classified under heading 9503, the last in numerical order.

Rule four: Most akin (of similar character) 

Goods which cannot be classified in accordance with the above rules shall be classified under the heading appropriate to the goods which they are most akin.

For example, there isn’t a clear heading for “plastic diffuser.” In this case, since its use isn’t understood, the most proximate and appropriate heading would be 3926, “items of plastic.”

Rule five: Containers 

5(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…, 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.

5(b): Subject to the provisions of rule 5(a) above, packing materials and packing containers entered 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.

5(a) applies to long-term use cases, boxes, and containers when they’re made for the product inside and are classified together (both the product and the case). For example, a “drone” alone is classified in 8806, “Unmanned aircraft,” and if the drone came with a case, the heading would remain 8806 for both items.

5(b) applies to packaging cases, boxes, and containers that are not intended to be reused. For example, a cardboard box with saltwater taffies inside should be classified as saltwater taffies.

Rule six: Subheading rule 

For legal purposes, the classification of goods in the subheadings of a heading shall be determined according to the terms of those subheadings and any related subheading notes on the understanding that only subheadings at the same level are comparable. For the purposes of this rule, the relative Section and Chapter Notes also apply.

Rules 1-5 cover every use case to classify to the heading level. Once you’ve selected your heading, you reapply rules 1-5 to determine your subheading classification.

For example, if you’re classifying a “Duracell battery,” you should have selected heading 8507, “Electric accumulators,” by following rule 3(a). From there, you’d select the subheading 8507.60, “Lithium,” based on reapplying rule 3(b), the product’s essential character.


Exceptions to the universality of the six-digit WCO code classification structure do exist. Since every country has the autonomy to make determinations where certain goods fall into their tariff schedule, the door is open for goods to be sorted differently from country to country. For example, in the U.S., a metal food cart is classified as a metal cart, whereas in Canada it is classified as a kitchen tool. In this case, the classification for these two items will be found in different chapters. Although these divided classification results do exist, they are the exception, not the rule. In most cases, goods are classified in the same chapter, heading, and subheading from country to country.
