(Understanding D10-15-28 – Where Design Meets Law)
1. Introduction
In international trade, tariff classification is not determined by what a product is called, but by what it actually is.
A common misunderstanding arises in the classification of footwear described as “covering the ankle.”
The Canada Border Services Agency (CBSA), through Memorandum D10-15-28, provides a precise administrative policy to resolve this ambiguity.
2. Statement of Facts (From CBSA Policy)
The memorandum clarifies:
The expression “footwear, covering the ankle” appears in several tariff subheadings under Chapter 64, but is not defined in the Customs Tariff or Explanatory Notes.
This absence of statutory definition creates a need for interpretative guidance.
3. Administrative Policy (CBSA’s Approach)
CBSA adopts a practical and interpretative methodology, relying on:
- Dictionary meanings
- Anatomical understanding
- Ankle → Joint between the leg and foot
- Covering → Full protection or concealment
From this, CBSA formulates a functional test, rather than relying on commercial terminology.
4. The Core Legal Test (Decisive Principle)
Footwear must provide 100% total coverage of:
- Midfoot
- Hindfoot
- Malleolar Zone (ankle bone area, approx. 6 cm)
This is the determinative legal standard.
Even minimal deviation results in disqualification.
5. Anatomical Interpretation (Substance Over Form)
- The ankle is not a vague concept
- It is a defined 6 cm zone (malleolar region)
- Includes bones such as:
- Tibia
- Fibula
- Talus and Calcaneus
Classification is based on physical coverage of this anatomical zone, not visual appearance.
6. Disqualification Criteria
- ❌ Coverage is partial (even a small opening)
- ❌ Laces, straps, or ties leave gaps
- ❌ Upper contains cut-outs or perforations
“Even 1% exposure = failure of the test.”
7. Special Case – Open-Toe Footwear
Footwear may still qualify even if toes are not covered, provided:
- Midfoot is fully covered
- Hindfoot is fully covered
- Ankle (malleolar zone) is fully covered
This highlights that toe coverage is irrelevant for this classification.
8. Tariff Classification Impact
This interpretation directly affects classification under:
- 6401 – Waterproof footwear
- 6402 – Rubber/plastic footwear
- 6403 – Leather footwear
Impact areas:
- Duty rates
- Trade compliance
- Import valuation
9. Practical Examples
- ✔ Fully enclosed boot → Qualifies
- ❌ High-top shoe with lace gap → Disqualified
- ✔ Open-toe sandal with full ankle coverage → Qualifies
10. Pith and Substance (Legal Interpretation)
Pith (Purpose of Law):
To ensure uniform classification based on actual physical characteristics
Substance (Operational Reality):
The actual design, structure, and coverage of footwear
11. Key Legal Takeaways
- 100% ankle coverage is mandatory
- Partial coverage leads to disqualification
- Decorative or functional features do not substitute coverage
- ✔ Toe coverage is irrelevant
- ✔ Product name (e.g., “boot”) is legally irrelevant
12. Compliance Strategy for Importers
- Conduct physical inspection of footwear design
- Do not rely on supplier descriptions
- Seek Advance Ruling (D11-11-3) in uncertain cases
- Maintain proper classification documentation
13. Conclusion
Classification depends not on what the footwear is called, but on how completely it covers the ankle.
In customs law, precision of design determines duty liability.

Closing Insight
“In CBSA classification, even a small gap in footwear can create a significant duty consequence.”
Duty Insight:
- Boots (ankle-covered) → generally higher duty
- Shoes (below ankle) → generally lower duty
FAQs
Q: What is the safest approach for importers?
A: Classify footwear based on actual design and full ankle coverage, and seek an advance ruling if there is any doubt.
Q: Does the name “boot” or “shoe” affect duty?
A: No. Duty depends on actual physical characteristics.
Q: Is duty difference the reason behind this D-Memo?
A: No. The purpose is correct and uniform classification.
Q: Can an importer classify boots as shoes to pay lower duty?
A: No. Misclassification is not permitted.
Q: Why does ankle-covering footwear often attract higher duty?
A: Due to material, protection level, and tariff structure.
Q: Which classification generally attracts lower duty?
A: Footwear not covering the ankle (shoes, sandals, slippers).
