How is leather footwear classified? HS codes and EU labels

Two systems, two different rules, one tech pack. Customs measures the upper and the outer sole; the EU label measures the upper, the lining and the sole. They can disagree about the same shoe — and that is normal.

Most brands discover this the week the container ships. By then the strap composition is fixed, the sole is bonded and the heading is whatever the product happens to be. Here is how the two systems actually work, and what a tannery can put in your file.

What decides the HS heading of a leather shoe?

Two materials, and only two: the upper and the outer sole. Chapter 64 of the Harmonized System tells you how to measure them:

• Upper: the constituent material with the greatest external surface area. Accessories and reinforcements — ankle patches, edging, ornamentation, buckles, tabs, eyelet stays — are disregarded.
• Outer sole: the material with the greatest surface area in contact with the ground, again ignoring spikes, bars, studs and similar.

That "greatest surface area" wording is the whole game. A sandal with leather straps and a decorative textile trim is leather-upper. The same sandal with the proportions reversed drops into a different heading and, usually, a different duty rate.

Within 6403, the classic leather sandal has its own subheading: 6403.20 — footwear with outer soles of leather and uppers consisting of leather straps across the instep and around the big toe. If that describes your product, that is where it goes.

Two traps worth flagging. Composition leather (bonded or regenerated leather) counts as leather for the 6403 upper test but is a separate category on the consumer label — so a shoe can be "leather" for customs and not "leather" on the shelf. And the lining does not affect the heading at all; it only affects the label. Brands routinely assume the opposite.

What does the EU footwear label actually require?

Directive 94/11/EC governs it, and it is narrower than most tech packs assume. Three components must be identified — upper, lining and sock, outer sole — using four material categories: leather, coated leather, textile, and "other materials".

The rule of thumb: only a material covering 80 % or more of the surface of the upper, lining and sock (or 80 % of the volume of the outer sole) has to be declared. If no single material reaches 80 %, you declare the two main materials. The information can be a written indication or a pictogram, must be visible, legible and securely attached, and must appear on at least one shoe of the pair.

Note that the label test and the customs test can disagree on the same shoe, because one measures external surface and the other includes the lining and uses a volume test for the sole. That is normal. Document both.

What should the tannery give you for the file?

If you buy from an intermediary, you will usually get a colour name and a price. That is not a file. What actually travels with a compliance dossier:

• Exact article and finish reference — not "black calf", but the article code and finish family, because that is what a customs ruling or a lab report will cite.
• Species and origin of the hide, which feeds both the label category and your traceability claim.
• Tannery certification with number and expiry. An LWG Gold certificate is a third-party scheme, so it survives scrutiny that a self-declared "eco" claim does not.
• Batch continuity — a written commitment of 12–24 months, so a repeat order does not silently change the material and, with it, the classification.

We tan in Elda, Alicante, and have done since 1995, which means the article reference on your tech pack points at a real production recipe in one plant rather than at a warehouse lot of unknown origin. If you are still deciding which leather goes on the upper, the types of leather for footwear guide and leather for shoes cover the material side. Full grain vs corrected grain vs split matters here too, because a split with a heavy coating may end up declared as coated leather.

For the wider export paperwork — invoices, certificates of origin, incoterms — see how to export leather goods. On deforestation reporting, see EUDR and leather, and on the certification itself, LWG Gold certified Spanish tannery. If you want a physical reference of the exact article before you freeze the tech pack, request samples — stock articles ship in 1–2 weeks.

When should you fix the classification?

At the tech pack, before the last sample round. Three reasons:

1. Duty rates differ by heading. A change of a few square centimetres of strap can move a sandal between 6403 and 6404. Verify the live TARIC or HTS rate for your exact code before you price the collection.
2. The label follows the bill of materials. Once the lining is approved, the pictogram set is decided. Changing it later means re-artworking, re-printing and, if you are already in market, relabelling.
3. Repeat orders inherit the error. A misclassification that survives one season becomes the default for every reorder, which is how small brands end up with retroactive duty assessments.
