The HS code you declare decides your duty rate, whether a permit applies, and whether anti-dumping duty bites. Two reasonable people can classify the same product differently — and the difference can be 0% versus 45%. This guide covers how classification actually works under South African law, how to resolve a disagreement with SARS, and how to lock in certainty with a binding tariff determination.
How the SA tariff is structured
South Africa's tariff is Schedule 1 Part 1 of the Customs & Excise Act. It is built on the World Customs Organisation's Harmonized System: the first six digits are international and identical worldwide; South Africa adds further digits for its own rates and statistics.
Each chapter and heading carries legal Section Notes and Chapter Notes that bind the classification — they are not optional commentary.
The General Rules of Interpretation (GRI)
Classification is not a guessing game — it follows six rules applied in order. You only move to the next rule if the current one does not resolve the matter.
| Rule | What it does |
|---|---|
| GRI 1 | Classify by the terms of the headings and the Section/Chapter Notes — the starting point for everything |
| GRI 2 | Incomplete/unassembled goods and mixtures of materials |
| GRI 3 | Goods classifiable under two headings: most specific wins; else essential character; else last in numerical order |
| GRI 4 | Goods most akin (rarely used) |
| GRI 5 | Cases, packing and containers |
| GRI 6 | Subheadings classified on the same principles, comparing like with like |
Worked example: a "smart watch"
Is it a wristwatch (Chapter 91) or a data-transmission/communication device (heading 8517)? Under GRI 3(b) you look at essential character. A device whose principal function is communicating with a phone over Bluetooth is generally classified by that function, not as a timepiece — which changes both the duty rate and the applicable standards.
Getting certainty: apply for a tariff determination
If your product is borderline, do not guess shipment after shipment. Apply to SARS for a tariff determination — a formal, binding ruling on the correct classification. It is the single best protection against a future back-assessment.
- Submit a written application to the SARS Tariff & Trade unit describing the goods in full
- Include technical specs, brochures, photos, composition breakdowns and a sample where practical
- State the heading you believe applies and your reasoning under the GRI
- SARS issues a determination letter stating the binding HS code
A determination is generally effective from the date of the goods entered and is binding on you and SARS until amended or withdrawn — for example if the tariff changes or the determination was based on incorrect information. Keep it on file and quote it on your declarations.
If you disagree with SARS
- Internal appeal: dispute the determination through SARS's internal administrative appeal process
- Litigation: failing that, take the determination on appeal to the High Court (classification disputes are heard as appeals, with the court deciding the correct heading)
- Clear under protest: use a provisional payment to release cargo while the dispute runs, so you do not bleed demurrage and detention
Pro tip: get the code right once, then reuse it
For any product you import repeatedly, the cost of a tariff determination or a clearing-agent classification opinion is trivial against years of duty exposure. Settle it once and quote the same code every time.

Frequently asked questions
What is a SARS tariff determination?
A formal, binding ruling from SARS on the correct HS classification of your product. It is generally effective from the date the goods are entered and binds both you and SARS until amended or withdrawn — the single best protection against a future back-assessment when a product is borderline.
How do I apply for a tariff determination?
Submit a written application to the SARS Tariff & Trade unit describing the goods in full — technical specs, brochures, photos, composition breakdowns and a sample where practical — stating the heading you believe applies and your reasoning under the General Rules of Interpretation. SARS issues a determination letter with the binding HS code; keep it on file and quote it on declarations.
What are the General Rules of Interpretation (GRI)?
Six rules applied strictly in order to classify goods. GRI 1 — the terms of the headings and the binding Section and Chapter Notes — is the dominant test; GRI 3 resolves goods classifiable under two headings (most specific wins, then essential character); GRI 6 applies the same principles at subheading level. The WCO Explanatory Notes are the authoritative commentary courts rely on.
What can I do if I disagree with a SARS classification?
Dispute it through SARS's internal administrative appeal process, and failing that take the determination on appeal to the High Court. While the dispute runs, clear cargo under a provisional payment so it does not bleed demurrage and detention.
