Tariff Provision
A tariff provision is any enumerated entry in the HTSUS — a heading, subheading, or Chapter 99 overlay — that carries legal significance for classification, duty rates, or trade remedy applicability. The term encompasses every line of the tariff schedule, from a 4-digit heading to a 10-digit statistical annotation, as well as the legal notes that define and constrain each provision's scope.
In Detail
The HTSUS contains tens of thousands of individual tariff provisions. At the broadest level, provisions are headings (4-digit) and subheadings (6- and 8-digit). But the term also encompasses basket or residual entries (“Other”), grouping rows that introduce a category without themselves being a classification destination, and Chapter 99 overlay provisions that add tariff exposure on top of base-chapter rates. Each provision type has different legal characteristics and different rules governing when it can be used.
Every tariff provision is characterized by the type of description it uses. Eo nomine provisions name specific articles by type or commercial name (e.g., “ball bearings”). Use provisions classify goods based on their chief or principal use (e.g., “parts for use in aircraft”). Material or descriptive provisions classify goods by composition, construction, or function. The type of provision determines how it is interpreted, which GRI rules apply, and which Additional U.S. Rules of Interpretation govern.
The relationship between provisions within a heading is hierarchical: more specific provisions take precedence over more general ones under GRI 3(a). An eo nomine provision always prevails over a basket provision at the same indent level. A material-specific provision prevails over a functional description if both cover the goods. Understanding this hierarchy is essential to correctly identifying the most specific applicable provision — which is the goal of every classification.
Classification Significance
Identifying the correct tariff provision — not just the correct heading — is the end goal of classification. Two importers with functionally similar products may end up at different provisions within the same heading based on product attributes, and the duty rate, trade remedy exposure, and regulatory treatment can differ substantially between provisions just a few lines apart in the schedule.
How Kanon Handles This
Kanon's classification engine evaluates tariff provisions at every level — heading, subheading, and Chapter 99 overlay — producing a complete, linked provision chain for every classification. The Classification Support Package identifies the specific provision selected at each level and documents why competing provisions at the same level were excluded.
