Cold Chain: The Critical Success Factor for Chinese Citrus Imports
Maintaining the cold chain from Jiangxi orchard to European distribution center is the single most important factor determining fruit quality upon arrival. A break in the cold chain can reduce shelf life from 30+ days to under 7 days.
The Cold Chain Timeline
- Harvest → Pre-cooling (within 6 hours): Field heat removed; fruit temperature reduced from 25–30°C to 4–6°C
- Cold treatment (14–18 days): Mandatory EU requirement. Fruit held at 1–2°C for phytosanitary compliance
- Container loading: Precooled fruit loaded into temperature-controlled reefer containers at 2–3°C
- Ocean transit (32–42 days): Continuous temperature logging with alarm thresholds
- Port clearance: Temperature records reviewed by EU plant health authorities
- Distribution: Cold chain maintained through regional distribution centers

EU Cold Treatment Regulations
Since EU Implementing Regulation 2021/2244 (effective June 2022), all citrus imports from non-EU countries require:
- Temperature: 1–2°C for 14–18 consecutive days
- Monitoring: Digital temperature probes placed in fruit pulp
- Documentation: Continuous temperature logs reviewed at destination
- Compliance rate: GannanGrove has maintained 100% cold treatment compliance for 3+ years
Shelf Life Management
With proper cold chain management, Gannan navel oranges can achieve:
- 30–45 days from harvest under ideal conditions
- 14–21 days in retail display (10–15°C)
- 7–10 days in consumer refrigerator

Planning Your Shipment
Harvest timing directly impacts cold chain planning. See our 2026 Season Calendar to choose the best ordering window for your transit route. Container configuration also depends on fruit size — review our Size & Weight Guide for pallet and carton dimensions.
