1. The Role of Air Cargo in the Apparel Supply Chain
While ocean freight moves the bulk volume of apparel trade, Air Cargo is the lifeblood of fast-fashion supply chains, emergency production recovery, high-end runway collections, and e-commerce replenishment.
Air cargo delivers finished garments across continents in 24 to 72 hours, compared to 28 to 40 days for ocean transit. However, with air freight costs ranging from 3.00 to $6.50 per kg$ (versus0.15 to \0.35 per kg for ocean freight), optimizing every kilogram of chargeable weight is vital.

Air cargo is assembled into specialized aerodynamic aluminum containers and pallets called Unit Load Devices (ULDs):
- PMC / P6P Pallet: Flat aluminum pallet (2.44 m × 3.18 m) holding up to 6,800 kg and 11.5 - 15.0 CBM of stacked apparel secured with certified cargo netting.
- AKE / LD3 Container: Enclosed contoured aluminum box designed for wide-body belly holds (1.56 m × 1.53 m × 1.63 m), holding up to 1,588 kg and 4.3 CBM.
4. Air Freight Weight-Break Optimization Formula
Air freight tariffs use sliding weight-break brackets:
- Minimum Charge (M)
- Normal Rate (N): Under 45 kg
- +45 kg, +100 kg, +300 kg, +500 kg, +1,000 kg
Total Freight = ( Actual Weight × Bracket Rate, ; Next Tier Weight × Next Tier Rate )
Exporters should always evaluate the "as-weight" breakpoint to reduce total billing when close to the next tier.
1. Major Aircraft Unit Load Devices (ULD) Used in Apparel Air Cargo
| ULD Type / Code | IATA Identification | Base Dimensions (W × L) | Height | Max Gross Weight | Usable Apparel Volume | Compatible Aircraft |
|---|---|---|---|---|---|---|
| PMC / P6P Flat Pallet | Main deck / Lower deck pallet | 244 × 318 cm (96 × 125 in) | 163 – 244 cm | 6,804 kg (15,000 lbs) | 11.5 – 15.0 CBM | B777, B747, A330, A350 |
| PAG / P1P Flat Pallet | Standard wide-body pallet | 224 × 318 cm (88 × 125 in) | 163 – 244 cm | 6,033 kg (13,300 lbs) | 10.0 – 13.5 CBM | B777, B747, A330, A350 |
| AKE / LD3 Container | Contoured lower deck container | 156 × 153 cm (61.5 × 60.4 in) | 163 cm (64 in) | 1,588 kg (3,500 lbs) | 4.3 – 4.5 CBM | B777, B787, A330, A350 |
| AMF Container | Main deck contoured container | 244 × 318 cm (96 × 125 in) | 244 cm (96 in) | 6,800 kg (15,000 lbs) | 14.5 – 15.5 CBM | B747F, B777F Freighters |
2. Standard Air Cargo Rate Structure & Surcharge Components
| Cost Component | Code | Basis of Calculation | Typical Rate Range (South Asia to EU/US) | Paid By |
|---|---|---|---|---|
| Base Air Freight Rate | BAS / FREIGHT | Per kg of Chargeable Weight (Weight-break scale) | $2.80 – $5.50 / kg | Freight Payer (Buyer / Shipper) |
| Fuel Surcharge | FSC / MYC | Per kg of Chargeable Weight (Index linked to jet fuel) | $0.60 – $1.20 / kg | Freight Payer |
| Security Surcharge | SSC / SCC | Per kg of Chargeable Weight (Airport screening/security) | $0.10 – $0.25 / kg | Freight Payer |
| Terminal Handling Charge | THC / CGC | Per kg of Actual Gross Weight (Airport cargo handling) | $0.05 – $0.12 / kg | Shipper (Origin THC) |
| Airway Bill Documentation Fee | AWC / AWA | Flat fee per Master/House Air Waybill | $25.00 – $60.00 / shipment | Shipper (Factory) |
| Explosive Screening / X-Ray | X-RAY | Per kg of Gross Weight (Scanning fee) | $0.04 – $0.08 / kg | Shipper (Factory) |
Practical Commercial Flow
An apparel exporter in Gazipur must air-freight 4,500 pcs of polo shirts to Frankfurt (FRA) due to an urgent promotional deadline. Order details: 150 Cartons, 30 pcs/ctn. Carton size: 60 × 40 × 30 cm. Gross weight: 11.0 kg/carton.
Factory Real-Life Scenario
Scenario: A garment factory dispatched 250 cartons of woven shirts to Dhaka Airport Cargo Village 6 hours before scheduled flight departure. Due to severe runway congestion and a long queue at the single operating Dual-View X-Ray scanner, the cargo missed the physical security cut-off time.
Solution: The airline offloaded the cargo to the next flight 24 hours later. To prevent missing the retail launch in London, the forwarder re-booked the shipment on a midnight freighter via Dubai (DXB) at an additional expedited transit surcharge.
Impact: The factory incurred an extra $1,200 in re-booking fees and emergency warehouse storage. The incident led to a new factory SOP mandating that all air cargo must arrive at the airport cargo village at least 18 hours prior to flight departure.
Commercial Officer Best Practice
For large air consignments, request your forwarder to perform "Airline Pallet Built-up" (BUP) directly at their airport CFS warehouse. Building shipper-owned ULDs earns a 5% to 10% carrier discount and reduces the risk of cargo crushing or carton loss during aircraft transit.
Top Beginner Mistakes to Avoid
- Arriving at the airport cargo terminal too close to flight cut-off during peak export rush hours.
- Underestimating volumetric weight on low-density apparel, resulting in massive unexpected freight invoices.
- Failing to verify that destination airport customs clearance is ready before booking express flights.
- Packing liquid fabric sprays, perfume samples, or button batteries inside apparel cartons without DGR documentation.
- Misdeclaring piece count or gross weight on the Air Waybill, triggering airline customs audits and physical re-checks.
