Eo Nomine
/ˌiːoʊ ˈnɑːmɪniː/
An eo nomine provision identifies an article by name. Its scope is determined under GRI 1 from the provision’s text, relevant legal notes, and controlling interpretation, and it generally covers all forms of the named article unless limited. If two headings remain prima facie applicable, GRI 3—not the eo nomine label alone—resolves the competition.
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 two key implications, applied through ordinary GRI 1 and GRI 3 analysis rather than as an automatic override. First, an eo nomine provision generally covers the named article in all its commercial forms and materials — a heading for "ball bearings" presumptively covers ball bearings of steel, ceramic, plastic, or any other material — unless the heading text, a legal note, or a use limitation narrows that scope. Second, GRI 2(a) extends eo nomine headings to unfinished articles that already have the essential character of the named article, and to the complete article presented unassembled.
When an eo nomine heading and a use or material heading both appear to describe the same goods, GRI 1 is applied first using the actual heading text and any relevant notes; if two or more headings remain prima facie applicable, GRI 3(a) then compares them as written to determine which gives the more specific description — the eo nomine label itself is not a shortcut past that comparison. A chapter note that excludes the article from an otherwise-applicable eo nomine heading, or a more specific named-article heading elsewhere, can also displace it.
Classification Significance
Correctly identifying an applicable eo nomine heading is an important part of GRI 1 analysis, since it often gives the clearest, most specific description of an article's commercial form. But identifying an eo nomine candidate does not by itself end the analysis — if the goods remain prima facie classifiable under a competing heading, GRI 3 still governs which one controls. Misclassifying an article that has a well-established eo nomine heading under a materials or use heading — or assuming the eo nomine label automatically wins a genuine GRI 3 competition — are both classification errors CBP corrects in rulings and audits.
How Kanon Handles This
Kanon's classification engine evaluates eo nomine headings as part of ordinary GRI 1 analysis — using the heading's actual text and any applicable legal notes to determine its scope, rather than treating the eo nomine label as an automatic priority rule. Where the goods remain prima facie classifiable under more than one heading after that analysis, Kanon applies GRI 3 to resolve the competition, documenting the reasoning in the Classification Support Package.
