Rule 4: Unit of Qualification – Revised Treaty of Chaguaramas

Each article in a consignment shall be considered separately.

For the purposes of paragraph 1 of this Rule –

(a) where the Harmonised Commodity Description and Coding System specifies that a group, set or assembly of articles is to be classified within a single heading, such a group, set or assembly shall be treated as one article;

(b) tools, parts and accessories which are imported with an article, and the price of which is included in that of the article or for which no separate charge is made, shall be considered as forming a whole with the article, provided that they constitute the standard equipment customarily included on the sale of articles of that kind;

(c) in cases not within sub-paragraphs (a) and (b), goods shall be treated as a single article if they are so treated for purposes of assessing Customs duties by the importing Member State.

An unassembled or disassembled article which is imported in more than one consignment because it is not feasible for transport or production reasons to import it in a single consignment shall, if the importer so requests, be treated as one article.
