Is air or sea cheaper from China to South Africa?
For a typical 200 kg in 1 m³ load: air is ~$1,560 (~R27,592) at $8/kg; sea ~$440 (~R7,782) at $180/CBM. The crossover is near ~100 kg or ~0.5 CBM: below it air closes the gap, above it sea wins clearly. Indicative figures, sampled 2026-06-07; not a quote.
| Mode | Cost (USD) | Local |
|---|---|---|
| Air | $1,560 | R27,592 |
| Sea (LCL) | $440 | R7,782 |
How do you calculate CBM and volumetric weight?
CBM = length × width × height in metres. A 40×30×25 cm carton = 0.03 m³; ten cartons = 0.3 m³. Air volumetric weight = CBM × 167 kg, and air is charged on the greater of actual and volumetric weight — light, bulky goods price on volume, not weight.
How long does shipping really take to South Africa?
Air is usually 5-10 days to arrival, plus clearing. Sea LCL is often 4-8 weeks door-to-port depending on the line and consolidation, plus clearing that stretches if documents are not ready. Plan to the longer end. South African imports clear through Durban and OR Tambo and sell through Johannesburg's CBD, China Malls and the wholesale trade. SARS runs the most schedule-driven tariff of these corridors: duty swings from 0% on many electronics to 45% on clothing, and VAT is charged on the ATV — the customs value plus a 10% uplift plus duty — not on the bare CIF.
What this estimate won't capture
Freight rates are indicative and move with season, fuel, route and consolidator. The numbers here build intuition; they do not replace a written quote from a forwarder for your specific shipment. Indicative figures, sampled 2026-06-07; not a quote.
Frequently asked questions
Is air or sea cheaper from China to South Africa?
Sea (LCL) is usually cheaper per kg once a shipment passes roughly 100 kg or about half a CBM. Air is faster and wins for light, urgent or high-value goods.
How do I calculate CBM?
CBM is length x width x height in metres. For cartons in cm, multiply L x W x H and divide by 1,000,000, then multiply by the number of cartons.
What is volumetric weight?
Air freight is charged on the greater of actual weight and volumetric weight. Bulky light goods can be charged on volume.
Are these freight rates accurate?
