Containerization Strategy: 20′, 40′ Standard, 40′ HC or Reefer?
Every Turkey-Senegal shipper eventually faces the same decision: which container type maximises cost-efficiency for this load? A miscalculation adds USD 800-2,500 per container or wastes 20% of volume. This guide gives the exact calculation framework used by the top Dakar importers.
Container specifications comparison
| Type | Internal volume | Payload | Internal dimensions (L×W×H) |
|---|---|---|---|
| 20′ standard | 33.2 m³ | ~28,200 kg | 5.90 × 2.35 × 2.39 m |
| 40′ standard | 67.7 m³ | ~28,800 kg | 12.03 × 2.35 × 2.39 m |
| 40′ HC (High Cube) | 76.3 m³ | ~28,700 kg | 12.03 × 2.35 × 2.69 m |
| 20′ reefer | 28.4 m³ | ~27,700 kg | 5.44 × 2.29 × 2.27 m |
| 40′ reefer HC | 67.3 m³ | ~27,600 kg | 11.56 × 2.29 × 2.55 m |
| 40′ open top | 66.7 m³ | ~26,500 kg | 12.03 × 2.35 × 2.35 m |
| 40′ flat rack | — | ~40,000 kg | 12.03 × 2.35 × — (no sides) |
Freight rate comparison Turkey-Dakar 2025-2026
- 20′ standard via transshipment: USD 1,200-1,800
- 40′ standard: USD 2,000-2,800
- 40′ HC: USD 2,100-2,900 (+USD 100-200 vs standard)
- 20′ reefer: USD 2,800-3,800
- 40′ reefer HC: USD 4,500-6,500
- 40′ open top: USD 3,500-4,800 (oversized cargo)
The break-even rule 20′ vs 40′
- Below 30 m³ or 15,000 kg: 20′ is cheaper per m³
- 30-52 m³: borderline, depends on stowage efficiency
- Above 52 m³: 40′ standard or HC wins
- Above 67 m³: 40′ HC is optimal
- Never ship less than 75% of a 40′ HC unless goods are very dense (steel, ceramics)
By product category
40′ HC — optimal for most Turkey-Senegal cargo
- Textile rolls (high volume, low weight)
- Furniture (volumetric bulky)
- Home appliances
- Plastic packaging
- Toys & school supplies
- Cosmetics
40′ standard — when HC premium not justified
- Construction materials (tiles, ceramic sanitaryware)
- Chemical products in barrels
- Canned food
20′ standard — low volume or split cargo
- First-time pilot orders < USD 25,000 CIF
- Dense heavy products (steel bars, pipes, cement)
- Test shipments with new supplier
40′ reefer HC — temperature-controlled
- Dairy products (yoghurt Pınar, Sütaş)
- Chocolate (Ülker premium, Mehmet Efendi)
- Cosmetics with thermo-sensitive ingredients
- Pharmaceuticals requiring 2-8°C
- Fresh or frozen food
40′ open top — oversized cargo
- Industrial machinery (textile looms, solar inverters > 2.4 m tall)
- Construction equipment
40′ flat rack — extra-wide or very heavy
- Steel beams, transformers, boats
- Single items > 26.5 m³ or > 28 t
Consolidation (LCL) vs Full Container (FCL)
- LCL (less-than-container load): shared space, priced per m³
- Istanbul-Dakar LCL rate: USD 85-140/m³
- Break-even: above ~15-18 m³, FCL becomes cheaper
- LCL adds 5-10 days transit (consolidation time)
- Providers Istanbul: Kuehne+Nagel, DHL Global Forwarding, DB Schenker, Hellmann
Stowage optimisation tips
- Use EUR 120 × 80 cm pallets: exactly 10 per row, 30 per 40′ HC
- Stack height: max 2.20 m (leave 20 cm clearance for ventilation and handling)
- Heavy products at bottom, light at top
- Disassemble furniture to flat-pack: save 40-55% volume
- Vacuum-compress mattresses: save 70% volume
- Nested stacking (pots, basins): save 30-50%
Demurrage & detention warning
- Port of Dakar: 7 days free, then USD 135/day standard, USD 95/day detention outside port
- Reefer: USD 180-240/day demurrage (higher due to plug-in cost)
- Open top and flat rack: often higher, 20% premium
- Plan clearance within 5 days to stay within free period
Bottom Line
For 80% of Turkey-Senegal trade, 40′ HC is the optimal container. 20′ makes sense only for pilot orders or dense heavy cargo. Reefer is mandatory for dairy, chocolate, pharma. Never ship below 75% fill — use LCL consolidation or delay until volume justifies FCL. A correct containerization decision saves USD 800-2,500 per shipment, compounding USD 10,000-30,000 per year for mid-size importers.
