Updated September 2026. "Customs clearing" and "customs clearance" mean the same thing: getting SARS to release your goods so they can leave the port or airport. This guide is written for South African businesses importing commercially, especially from China and Asia, and it is the process we run for our own clients every week.
Why clearing is where shipments go wrong
The ocean or air leg is the predictable part. Most real-world delays happen at the border: a missing document, a valuation query, a tariff heading dispute or an inspection. Good clearing work is mostly preparation: having the paperwork right before the cargo arrives, so the declaration can be lodged and released while the vessel is still at sea.
Customs clearing in South Africa, step by step
- Register as an importer with SARS. Once-off. You get a customs client number (importer's code) that goes on every declaration. Done through SARS eFiling under Registration, Licensing and Accreditation. Allow one to three weeks; do it before you pay a supplier deposit, not when the goods land.
- Get the documents from your supplier before the goods ship. Commercial invoice, packing list and, once loaded, the bill of lading or air waybill. Check that the three agree with each other on quantities, descriptions and consignee. Most stops trace back to a mismatch here.
- Classify the goods. Every product has a tariff heading in the SARS Customs Tariff (Schedule 1). The heading decides the duty rate. Your clearing agent does this, but ask to see the code and the rate on the quote.
- Check permits. Used goods, many electrical and electronic items (NRCS letter of authority), foodstuffs, cosmetics, medicines, chemicals and some textiles need permits or letters of authority before entry. Applying after arrival means storage charges while you wait.
- Lodge the declaration (SAD500) with SARS. Your agent submits it electronically, usually before the vessel berths. SARS responds with a release, a documentary query, or a physical inspection instruction.
- Pay duty and VAT. Either from your own deferment account with SARS or through the agent's account (they pay, you reimburse). Nothing is released until this is settled.
- Port or airline release and delivery. Once SARS releases the entry, the shipping line or airline releases the cargo against payment of their charges, and the container or pallets are collected and delivered to you.
The core documents
- Commercial invoice: the basis for customs value. It must honestly reflect the price paid, the currency and the incoterm (FOB, CIF, EXW and so on).
- Packing list: what is in each carton or pallet, with weights and dimensions. Customs and inspectors work from this.
- Transport document: the bill of lading (sea) or air waybill (air), proving carriage and naming the consignee.
- Customs declaration (SAD500): filed with SARS by your clearing agent, using the correct tariff classification.
- Certificate of origin: where a trade agreement gives the goods a preferential duty rate.
- Permits and letters of authority: for controlled categories as above.
- Proof of payment to the supplier: increasingly requested on valuation queries, so keep it with the file.
What it costs: duty, VAT and clearing fees
Three groups of cost sit on top of the freight:
- Customs duty: a percentage set by the tariff heading. Many headings are duty-free (much industrial machinery, for example); clothing, footwear and some finished consumer goods carry 20% to 45%. Classification is therefore not admin, it is money.
- Import VAT at 15%: calculated on the added tax value: customs value, plus duty, plus a 10% uplift on the customs value for goods from outside the Southern African Customs Union. VAT-registered importers claim it back as input VAT on the next return.
- Clearing and port charges: the agent's fee per entry, plus disbursements such as shipping line release fees, cargo dues, terminal handling, container deposit, and any SARS inspection or unpack fees. Ask for these to be itemised.
Worked example: goods with a customs value of R100 000 from China, at a 10% duty rate. Duty = R10 000. Added tax value = R100 000 + R10 000 + R10 000 (10% uplift) = R120 000. Import VAT = R18 000. Cash needed at clearing, before freight and handling: R28 000, of which R18 000 is typically recoverable as input VAT.
How long it takes
With documents lodged before arrival and no inspection, release is routinely same-day to two days after the vessel berths. A documentary query adds one to three days if answered immediately. A physical inspection at Durban can add three to ten days depending on the queue. Every day a container sits after free time expires costs storage and demurrage, so the difference between a prepared file and a reactive one is real money.
The five mistakes that get shipments stopped
- Invoice undervaluation. Suppliers sometimes offer to "lower the invoice" to save you duty. SARS compares declared values against reference prices; a low value triggers a query, a penalty and a reputation flag on your importer code.
- Wrong or lazy tariff code. Two importers with the same product can pay 15% apart in duty. Have the code checked, and keep the reasoning on file.
- No NRCS letter of authority for electrical goods, lighting, appliances or vehicle parts. The letter takes weeks; apply before the goods ship.
- Documents that disagree. Invoice says 480 units, packing list says 500, bill of lading says 20 cartons. Any inspector will stop it.
- Importing without your own code on a friend's or an agent's code. It is not allowed for commercial imports and it leaves you with no VAT claim.
Pre-shipment checklist
- SARS importer code active and matching the company name on the invoice.
- Commercial invoice with incoterm, currency, HS code suggestion and supplier details.
- Packing list with per-carton contents, gross and net weights, dimensions.
- Tariff classification confirmed and duty rate known.
- Permits or letters of authority in hand for controlled goods.
- Bill of lading or air waybill consignee and notify party correct.
- Cash for duty and VAT available for the week of arrival.

Customs clearing is one of our core services, handled by the same people who book and track your freight: classification, declarations, permits, compliance and bonded warehousing, with one accountable contact instead of a hand-off between a forwarder and a separate clearing agent. We check every file against the list above before the cargo sails. See our services, the China to South Africa guide, or send us your documents for a free pre-check.
