19 CFR Part 152: Mixtures and Combinations of Materials: GRI 2(b) and its Interaction with GRI 3
Under 19 CFR Part 152 (U.S. CBP / 19 CFR / HTSUS), mixtures and Combinations of Materials: GRI 2(b) and its Interaction with GRI 3 establishes the authoritative rules tested on the U.S. Customs Broker (CBLE). This lesson details how GRI 2(b) applies to mixtures and combinations of materials, focusing on identifying essential character and its interplay with GRI 3 for classification., verified against VoraPrep's U.S. Customs Broker (CBLE) blueprint.
Core Statutory Concepts
| Rule | Application | Key Principle |
|---|---|---|
| GRI 2(b) | Extends headings to include mixtures/combinations of a material with others. | Expands scope of material-specific headings. |
| GRI 3(b) | Classifies mixtures/composite goods by essential character when GRI 3(a) doesn't apply. | Determines the most significant component. |
| GRI 3(a) | Specific heading over general heading. | Most specific description prevails. |
| GRI 3(c) | Last resort; heading occurring last in numerical order. | Residual rule for unclassifiable goods. |
An importer brings in a novel type of insulated food container, constructed primarily of durable plastic, with a separate but integrated silicone seal. This container is equally classifiable under Heading 3924 ('Tableware, kitchenware, other household articles and hygienic or toilet articles, of plastics') and Heading 9617 ('Vacuum flasks and other vacuum vessels, complete with cases; parts thereof other than glass inners'). After applying GRI 3(a) and 3(b), neither heading is deemed more specific, nor does one component provide the essential character. Given these circumstances, how should the insulated food container be classified under the General Rules of Interpretation (GRIs)?
Practitioner Application: Mixtures and Combinations of Materials: GRI 2(b) and its Interaction with GRI 3
A customs broker is classifying a product marketed as a 'nutritional supplement bar.' The bar contains 40% oats, 30% dried fruit, 20% whey protein isolate, and 10% vitamins and minerals. The client argues it should be classified as a food preparation of cereals (HTS 1904) due to the oats, while CBP suggests it's a preparation of protein concentrates (HTS 2106) due to the protein content. Applying GRI 2(b) and potentially GRI 3, the broker must accurately determine the essential character to avoid misclassification and potential penalties, especially given the complex mixture of ingredients and the differing interpretations.
- General Rule of Interpretation 2(b) addresses the classification of mixtures and combinations of materials or substances. It states that any reference to a material or substance in a heading shall be taken to include mixtures or combinations of that material or substance with other materials or substances. The classification of goods consisting of more than one material or substance is to be according to the principles of GRI 3. Essentially, GRI 2(b) expands the scope of a heading to include mixtures, but then defers to GRI 3 for the actual classification when multiple materials are present.
- The core concept under GRI 2(b) and its interaction with GRI 3 is the identification of the essential character of the goods. This is particularly relevant when applying GRI 3(b), which dictates that mixtures, composite goods consisting of different materials or made up of different components, and goods put up in sets for retail sale, which cannot be classified by reference to GRI 3(a), shall be classified as if they consisted of the material or component which gives them their essential character.
Common U.S. Customs Broker (CBLE) Distractors on 19 CFR Part 152
- 1Test-takers often struggle with distinguishing when to apply GRI 2(b) versus immediately jumping to GRI 3, and accurately identifying the 'essential character.'
- 2GRI 2(b) expands scope, GRI 3 classifies: Remember that GRI 2(b) allows headings to cover mixtures, but GRI 3 is the rule that actually classifies them when multiple materials are involved.
- 3Essential Character is paramount for GRI 3(b): When GRI 3(a) doesn't apply, accurately identifying the essential character is critical. Consider factors like bulk, quantity, weight, value, and especially the role in use or primary function.
- 4Hierarchy of GRIs: Always follow the GRIs in numerical order (GRI 1 -> GRI 2(a)/2(b) -> GRI 3(a) -> GRI 3(b) -> GRI 3(c) -> GRI 4 -> GRI 5 -> GRI 6).
- 5Check Notes First: Section and Chapter Notes can provide specific instructions for mixtures or composite goods that take precedence over the general application of the GRIs.
