HTS section notes (covering multiple chapters) and chapter notes (covering one chapter) define and limit the scope of headings. Notes often: (1) include goods that the heading text alone might not cover, (2) exclude goods to a different section/chapter, (3) define key terms used in headings.
This guide covers HTS Section and Chapter Notes Interpretation. HTS classification is the legal foundation of import duty calculation.
For SMB importers, the practical implementation depends on volume, sector, and operational structure.
Including notes
Some notes specifically include goods within a heading despite ambiguous text. Read carefully – these can change classification.
Excluding notes
Some notes specifically exclude goods to a different chapter. Critical for goods at boundaries.
Defining terms
Many notes define key terms (e.g., “machinery,” “electrical apparatus,” “textile fiber”). Definitions control over ordinary meaning.
Conditional rules
Some notes establish conditional rules (e.g., “of plastics” requires specific plastic content percentages).
Frequently asked questions
When does this apply?
For SMB importers with active duty exposure or those evaluating mitigation options.
What documentation is required?
Standard CBP forms plus topic-specific supporting records. We review documentation as part of typical engagements.
What is the timeline?
Simple cases 2-4 weeks; complex setups 8-16 weeks.
What does this cost?
Project work: $5,000-$25,000 depending on complexity. Ongoing retainer for active operations.
