Chestnut shipping fails in the details: a reefer set to "closed" ventilation on a fresh load, a phytosanitary certificate with a mismatched container number, a document chain that misses the L/C deadline. This guide covers the settings and sequence that get consignments through clean.
Container & Settings
Fresh in-shell: ventilated reefer, 0°C to -1°C, 90%+ RH, vents open (chestnuts respire — trapped CO2 builds acidity and off-flavors). 20' or 40' high-cube. Never ship fresh chestnuts in a sealed container for long hauls. IQF kernels: standard reefer at -18°C, closed vents, cartons on pallets. Pre-cool before stuffing — loading warm product into a cold box condenses moisture onto the load.
Port & Routing
Shandong-origin shipments move from Qingdao (Taishan growing region is 2-4 hours by truck). Liaoning (Dandong) ships via Dalian. Both ports run regular reefer services to Busan (1-2 days), Tokyo/Yokohama (3-5 days), Southeast Asia (7-12 days), EU base ports (28-38 days). Factor port dwell: Qingdao reefer dwell is currently ~3 days.
The Document Chain
Standard chain for a fresh shipment: commercial invoice + packing list → GACC phytosanitary certificate (2-3 working days) → certificate of origin (FORM E for ASEAN preference, FORM K for Korea — ask your customs broker which saves duty in your market) → COA (lab, done pre-shipment) → B/L. For frozen kernels: swap phytosanitary for health certificate. If paying by L/C, build the certificate processing time into the expiry date — the #1 documentation failure is an L/C that expires before certificates are issued.
Timeline Reality
From confirmed order to vessel for a first shipment with a new supplier: sample exchange (1 week) → production/grading (3-10 days) → lab COA (3-5 days) → documents (2-3 days) → loading. Plan 3-4 weeks, not 10 days, for the first order; repeat orders compress to 1-2 weeks. Peak-season (Oct-Nov) queues add a few days at every step.

Frequently Asked Questions
Do fresh chestnuts need ventilated containers?
Yes — fresh chestnuts are alive and respire. Reefers run with vents open; sealed long-haul transport causes CO2 buildup and quality loss.
Which certificate replaces phytosanitary for frozen kernels?
A health certificate issued by Chinese customs, plus the standard invoice/packing/COA chain. Frozen product is not subject to plant quarantine.
How long does the whole first order take?
Realistically 3-4 weeks from confirmed order to vessel for a new trading relationship: samples, grading, lab COA, certificates, and loading. Repeat orders run 1-2 weeks.
