What is the Harmonized System?
The Harmonized Commodity Description and Coding System — known simply as the HS — is maintained by the World Customs Organization (WCO) and used by more than 200 countries. Every manufactured or primary product in the world is assigned a 6-digit HS code. The first two digits identify the chapter (broad product category), the next two the heading, and the final two the subheading.
South Africa extends the 6-digit international HS code to 8 digits in the SARS Customs Tariff, adding two country-specific digits for more granular classification. The full 8-digit code is what must appear on your Bill of Entry and commercial invoice for customs purposes.
| Code level | Digits | Example (cotton T-shirt) | What it identifies |
|---|---|---|---|
| Chapter | 61 | 61 | Knitted or crocheted clothing & accessories |
| Heading | 6109 | 6109 | T-shirts, singlets and similar garments |
| Subheading (HS) | 6109.10 | 6109.10 | Of cotton |
| SA tariff code | 6109.10.10 | 6109.10.10 | SA-specific subdivision; 45% duty |
Why tariff classification matters — it sets your duty rate
Every 8-digit SA tariff code has a corresponding duty rate in the SARS Tariff Book (Schedules 1–6). A single digit difference can result in dramatically different rates. Consider these three codes for similar display products:
| SA Tariff Code | Description | General duty rate |
|---|---|---|
| 8528.72.20 | Colour TV monitors, LCD, >72cm diagonal | 5% |
| 8528.59.10 | Monitors of a kind used with ADP machines | 0% |
| 8528.72.90 | Other colour TV monitors | 20% |
On a R500,000 CIF shipment, the difference between 0% and 20% duty is R100,000. Classification is not a technicality — it directly determines your landed cost.
Classification also determines whether you need an ITAC import permit (restricted goods under Schedule 2 of the Customs Act), whether anti-dumping or countervailing duties apply (Schedules 2 and 4), and whether rebate or SADC/AfCFTA preferential rates are available.
How to find your SA tariff code
There are four reliable methods, from quickest to most authoritative:
1. SARS Tariff Search (online)
Go to sars.gov.za → Customs & Excise → Tariff → Customs Tariff Book. The online search lets you enter keywords (e.g. "wireless headphones") and browse matching headings and subheadings. This is the live version — always use it rather than outdated PDFs.
2. WCO HS Nomenclature + General Rules of Interpretation (GRI)
The WCO publishes 6 General Rules of Interpretation that set the legal methodology for classification. GRI 1 says: classify first by the terms of the heading and the relevant section/chapter notes. GRI 3 covers goods that could go in multiple headings (the "most specific description" wins). Understanding the GRIs is essential for ambiguous products — your clearing agent should know them.
3. Ask a licensed customs clearing agent
For novel or complex products — machinery with multiple functions, multi-component kits, chemical compounds — a qualified customs clearing agent or a customs attorney with tariff classification experience is the safest route. Their classification advice is professional and they can defend it if SARS queries the entry.
4. Apply for a SARS Binding Tariff Determination (BTD)
A BTD is a written ruling from SARS confirming the correct tariff code for your specific product. It is legally binding on both you and SARS for 3 years. You apply via eFiling, submitting product samples, specifications, technical data sheets and a proposed classification with justification. Processing takes 60–90 business days. A BTD is worth the wait for high-value, recurring imports — especially if you face anti-dumping risk.
Consequences of getting your HS code wrong
Misclassification — whether deliberate or accidental — has serious consequences under the Customs and Excise Act:
| Consequence | Detail |
|---|---|
| Short-payment of duty | SARS will raise a demand for the underpaid duty plus interest (currently prime + 1% per annum, compounded monthly) |
| Administrative penalty | 10% of the value of the incorrect entry (section 88 of the Customs Act); can be reduced for voluntary disclosure |
| Goods detained / seized | SARS may hold the consignment pending correct classification and payment; storage costs accrue daily |
| Criminal prosecution | If misclassification is found to be deliberate (fraud), penalties include fines of up to 3× the value of goods and/or imprisonment |
| Permit violation | If the correct code requires an ITAC permit you didn't obtain, SARS can reject the entry entirely |
Preferential duty rates: SADC, AGOA and AfCFTA
South Africa is party to several trade agreements that reduce or eliminate duty on qualifying goods. Your tariff code unlocks the applicable preference — but only if you have the correct Certificate of Origin (or the supplier's Declaration of Origin for SADC):
| Agreement | Origin required | Benefit |
|---|---|---|
| SADC (Southern African Development Community) | SADC member state (e.g. Zimbabwe, Mozambique, Zambia) | Reduced or 0% duty on many Schedule 1 tariff lines |
| AGOA (African Growth and Opportunity Act) | Qualifying African countries exporting to the US (SA benefits on exports, not imports) | Duty-free access to US market for SA exports |
| AfCFTA (African Continental Free Trade Area) | AU member states that have ratified and scheduled tariff offers | Phased tariff reduction; still being implemented as of 2026 |
| EU-SADC EPA | EU member states importing from SA (SA gains reduced EU duty; EU goods may face reduced SA duty) | Phased liberalisation on specific schedule items |
Preferential rates are published in Schedule 1 Part 2 (SADC), Part 3 (EU-SADC), and Part 4 (other EPA) of the SARS Tariff. Your clearing agent will claim the preference rate on the entry; you supply the required certificate.

What is the difference between an HS code and a tariff code?
The 6-digit HS code is the international standard set by the WCO. A tariff code (or customs code) is what individual countries create by extending the HS. South Africa uses 8-digit tariff codes — the first 6 digits match the international HS, the last 2 are SA-specific subdivisions. When someone says "HS code" in a South African import context, they usually mean the full 8-digit SA tariff code.
Can I classify my product myself, or do I need a clearing agent?
Legally the importer is responsible for the correct classification on the Bill of Entry, but in practice your licensed clearing agent classifies and lodges the entry. For straightforward products, this works well. For complex, multi-function, or borderline products, it's worth consulting a customs consultant or applying for a Binding Tariff Determination before your first shipment.
How often do HS codes change?
The WCO updates the HS nomenclature every 5–6 years (last major revision: HS 2022). SARS also amends the SA-specific digits through Government Gazette notices, sometimes in line with Budget announcements or trade-agreement schedule changes. If you import regularly, check the SARS Tariff Book at least annually — codes you've used for years can be revised.
What is a Binding Tariff Determination (BTD) and how long does it take?
A BTD is a written SARS ruling confirming the correct 8-digit tariff code for a specific product. It is legally binding for 3 years. Apply via eFiling with product samples, technical specs, and your proposed classification with reasoning. Processing typically takes 60–90 business days. It is most useful for high-value recurring shipments or borderline products.
My supplier puts a different HS code on the invoice — what should I do?
The code your foreign supplier uses in their country may not match the SA 8-digit tariff code. Supplier-provided codes are a useful starting point but are not authoritative for South African customs purposes. Your clearing agent must classify the goods under the SA Tariff Book independently. If in doubt, cross-check via the SARS online tariff search or a BTD.
