GRI Application

Order of Inquiry

/ˈɔːrdər əv ɪnˈkwaɪəri/

The Order of Inquiry refers to the systematic application of the General Rules of Interpretation (GRI) to classify goods under the HTSUS. Classification begins under GRI 1, using the terms of the headings and relevant section or chapter notes. GRI 2 may expand those heading terms to include incomplete, unassembled, mixed, or combined goods. GRI 3 resolves specific competitions among headings when goods are prima facie classifiable under two or more. GRI 4 applies when goods cannot be classified under the preceding rules. GRI 5 provides special rules for certain cases, such as containers and packing. Finally, GRI 6 governs classification among subheadings within the chosen heading, applying the preceding rules as appropriate.


In Detail

The General Rules of Interpretation (GRI) establish a systematic approach to HTSUS classification, but they do not always operate as a strict linear fallback sequence. GRI 1 is the primary rule, requiring classification based on the terms of the headings and any relevant Section or Chapter Notes. If GRI 1 alone is insufficient, GRI 2 expands the scope of heading terms: GRI 2(a) applies headings to incomplete or unfinished goods and unassembled or disassembled articles, provided they have the essential character of the complete article. GRI 2(b) extends heading coverage to goods consisting of mixtures or combinations of materials or substances, and goods consisting of two or more materials or substances. These aspects of GRI 2 often inform or expand the initial assessment under GRI 1.

If goods are prima facie classifiable under two or more headings (e.g., after considering GRI 1 and GRI 2), GRI 3 provides criteria to resolve this competition. It operates as a strict internal sequence: GRI 3(a) prioritizes the heading that provides the most specific description; if that fails, GRI 3(b) assigns classification to the component giving the goods their essential character; and if neither 3(a) nor 3(b) resolves the issue, GRI 3(c) mandates classification under the heading that occurs last in numerical order among those equally meriting consideration. GRI 4 is a residual rule, applied only when goods cannot be classified under GRIs 1, 2, or 3. It directs classification under the heading appropriate to goods to which they are most akin. GRI 5 provides special rules for specific situations: GRI 5(a) addresses cases and containers specially shaped or fitted for the article, imported with it; GRI 5(b) covers packing materials and containers for retail sale.

GRI 6 operates distinctly, governing classification at the subheading (six-digit and eight-digit) level within a chosen heading. Once a heading is determined by applying GRIs 1 through 5, GRI 6 requires that the classification among subheadings within that heading be determined by applying GRIs 1 through 5 *mutatis mutandis* — meaning with necessary changes or adjustments. This signifies a new, focused inquiry at a more granular level, confined by the scope of the previously determined heading, and using the same principles of interpretation.

Classification Significance

Effective HTSUS classification requires demonstrating a thorough and accurate application of the General Rules of Interpretation. While not a rigid 1-through-6 staircase, the *conditional language* of each GRI dictates when and how it is applied. For example, invoking GRI 3 requires showing that goods are prima facie classifiable under two or more headings and that neither GRI 1 nor GRI 2 provided a singular classification. Similarly, GRI 4 can only be applied if goods cannot be classified under GRIs 1, 2, or 3. Documenting the analytical path and the *reasons* for applying each rule according to its specific conditions is crucial for satisfying reasonable care standards and defending classifications during CBP audits or focused assessments. Insufficiently supported classification reasoning is a common area of scrutiny.

How Kanon Handles This

Kanon's classification engine systematically applies the General Rules of Interpretation, evaluating the conditions for each rule's applicability. This ensures that classifications are not merely numerically sequential but are legally sound, applying each GRI rule according to its specific function and conditional requirements. Kanon's Classification Support Package documents this analytical process, clearly indicating which rules were considered, why they were applied, or why they were deemed inapplicable, providing robust documentation to satisfy CBP's reasonable care expectations.
