Eo Nomine
Eo nomine (Latin: "by name") describes a tariff provision that names a specific article rather than describing its material composition or its use. An eo nomine heading is generally the most specific classification for the named article and, under GRI 3(a), takes precedence over competing use or material headings when two headings appear to apply.
In Detail
An eo nomine heading classifies an article by its commercial name — "ball bearings," "scissors," "electric motors," "wristwatches," "typewriters." This naming approach provides the clearest and most certain classification anchor because it removes ambiguity: if a product is the named article, it classifies under the eo nomine heading regardless of what material it is made of or what it is used for, unless an applicable note restricts the heading's scope.
The eo nomine principle carries several important legal implications. First, an eo nomine provision covers the named article in all its commercial forms. A heading for "ball bearings" covers ball bearings of steel, ceramic, plastic, or any other material — the material heading for those materials cannot compete. Second, an eo nomine heading generally prevails over a use provision or material heading under GRI 3(a), because naming the specific article is a more precise description than describing a class of materials or a category of uses. Third, GRI 2(a) extends eo nomine headings to unfinished articles that already have the essential character of the named article.
The limits of eo nomine classification arise when the article is also specifically named in another heading, or when a chapter note excludes it from the heading that would otherwise apply eo nomine. In those situations, the note hierarchy under GRI 1 or the specificity analysis under GRI 3(a) resolves the competition.
Classification Significance
Identifying applicable eo nomine headings is the primary objective of GRI 1 analysis. Misclassifying an article that has an eo nomine heading under a materials or use heading is a fundamental classification error — and one that CBP consistently corrects in rulings and audits. Correct eo nomine identification eliminates the need for GRI 3 analysis in the majority of cases by providing an unambiguous, legally specific classification anchor.
How Kanon Handles This
Kanon's classification engine prioritizes eo nomine heading identification during GRI 1 evaluation. When an eo nomine heading applies and no note restricts its scope, it is treated as the primary classification candidate before material or use headings are considered — reflecting the legal hierarchy the GRI requires.
