A single temperature breach can destroy ¥2 million worth of wagyu. The margin between "A5 perfection" and "insurance claim" is maintaining -25°C continuously for 72-120 hours across 5 handoff points, 2 countries, and 3-4 different logistics providers.
The 5 Critical Temperature Handoff Points
| Stage | Target Temp | Risk Level | Duration |
|---|---|---|---|
| 1. Slaughterhouse → Blast Freezer | -35°C blast, -25°C storage | Low | 24-48h |
| 2. Cold Storage → Airport Warehouse | -25°C refrigerated truck | Medium | 2-6h |
| 3. Airport Cold Room → Aircraft | -20°C minimum | HIGH | 1-4h |
| 4. Aircraft Hold | -20°C (varies by aircraft) | Medium | 6-14h |
| 5. Destination Airport → Customs → Buyer | -18°C minimum | HIGH | 4-48h |
Packaging Standards for Frozen Wagyu Export
- Individual vacuum pack — each cut sealed in food-grade nylon/PE bags
- EPS (styrofoam) box — 25-30mm wall thickness minimum
- Dry ice — 3-5kg per 10kg of product for air freight
- Temperature logger — USB data logger inside each master carton (required by most importers)
- Outer cardboard — corrugated, with IATA perishable goods labels
Air Freight vs Sea Freight for Wagyu
| Factor | Air Freight | Sea Freight (Reefer) |
|---|---|---|
| Transit Time | 2-5 days | 14-30 days |
| Cost per kg | ¥800-1,500 | ¥200-400 |
| Min. Quantity | 10-50kg | 500kg+ (LCL) / 10t+ (FCL) |
| Temperature Risk | Lower (shorter exposure) | Higher (longer transit) |
| Best For | Premium cuts, samples, urgent orders | Bulk commodity cuts, regular supply |
Our recommendation: Use air freight for your first 3-5 orders to validate quality and build the relationship. Switch to sea freight reefer containers once you have steady volume above 500kg/month.

How long can frozen wagyu last in transit?
With proper packaging and dry ice, frozen wagyu maintains -18°C or below for 48-72 hours. Air freight transit rarely exceeds this window.
What happens if temperature is breached?
If the data logger shows temperatures above -15°C for more than 2 hours, the shipment may be rejected. Insurance typically covers temperature-related claims if the logger data confirms the breach.
Can I import wagyu by regular mail/courier?
No. Meat products require health certificates and customs clearance through designated ports of entry. Standard courier services cannot process these requirements.
What airports handle frozen wagyu from Japan?
Narita (NRT) and Kansai (KIX) are the primary export airports with MAFF-certified cold chain facilities. Haneda handles some cargo but has limited cold storage capacity.
