ruleHow to Classify in Chapter 28 — GRI Rules Applied
General Rules of Interpretation (GRI) — Simplified
- GRI 1: Classify by heading terms + section/chapter notes. Read the legal text, not just the title.
- GRI 2(a): Incomplete/unfinished articles = complete article if they have essential character.
- GRI 2(b): Mixtures/composites = material giving essential character.
- GRI 3(a): Most specific description wins over general.
- GRI 3(b): Essential character test for mixtures/sets.
- GRI 3(c): If equal, last in numerical order.
- GRI 4: If none apply, classify by analogy to closest.
- GRI 5: Packaging classified with goods unless for repetitive use.
- GRI 6: Subheading level: same rules, compare subheading texts.
Chapter 28 Specific Tips
- Check Chapter Notes first — they override headings (e.g., definitions of "knitted", "woven", "plastic").
- Read Section Notes — VI (Products of the Chemical or Allied Industries) may exclude certain materials.
- Use HS Explanatory Notes (WCO official commentary) for borderline cases.
- When in doubt, request binding ruling from destination customs (US: CBP ruling, EU: BTI, MX: SAT criterio).
- Document your reasoning — audits require proof of due diligence.
