Thailand is the world's largest exporter of fresh baby corn, accounting for the majority of global trade volume (FAOSTAT). Ratchaburi, Kanchanaburi and Nakhon Ratchasima provinces supply year-round harvests to buyers in Japan, Taiwan, South Korea, the USA and the EU. This guide walks through every step of a successful import — from the first supplier inquiry to the moment product arrives at your warehouse.
Thai baby corn falls under HS code 0709.99 (fresh or chilled vegetables, not elsewhere classified). Confirm this code with your customs broker before quoting duty rates — some markets sub-classify it differently.
Step-by-Step Import Process
Identify a Verified Exporter
Work only with exporters registered with Thailand's Department of Foreign Trade (DFT) and holding a valid FDA export licence. Ask for their GAP (Good Agricultural Practice) certificate from the Thai Department of Agriculture — this confirms pesticide compliance at farm level.
Agree on Product Specifications
Lock in cob length (4–9 cm standard), diameter (1–1.5 cm), colour (pale yellow), husk-on or husked, and pack format (loose carton, MAP tray or vacuum) before raising a purchase order. Misaligned specs are the most common cause of customs rejections.
Obtain a Phytosanitary Certificate
The Thai Department of Agriculture issues a Phytosanitary Certificate (PC) for each shipment. The PC confirms the consignment is free from regulated pests and meets your country's import conditions. Allow 1–2 business days for issuance after the exporter submits inspection documents.
Book Cold-Chain Logistics
Baby corn must be shipped at 4–6 °C throughout transit. For airfreight, book cargo space on a temperature-controlled ULD. For sea freight, use a reefer container set to 4 °C. Pre-cool product to target temperature before loading — do not load warm product into a cold truck.
Prepare Commercial Documents
A standard shipment requires: Commercial Invoice, Packing List, Bill of Lading / Airway Bill, Phytosanitary Certificate, Certificate of Origin (Form D for ASEAN buyers), and any destination-specific health certificate.
Clear Customs at Destination
File the import declaration with the correct HS code (0709.99 or local equivalent). Most markets require a phytosanitary inspection at the port of entry. Taiwan's BAPHIQ, Japan's Plant Protection Station and Korea's Animal and Plant Quarantine Agency all operate inspection desks at major airports and seaports.
Receive and Store
Move product directly from the customs cold store to your 4–6 °C warehouse. Under correct storage, Thai fresh baby corn has a shelf life of 10–12 days from harvest. Plan distribution to ensure product reaches end customers within this window.
Duty Rates by Market
| Market | MFN Duty | Preferential Duty | FTA Basis |

| Japan | 3% | 0% | AJCEP / JTEPA |
| South Korea | 27% | 0–5% | ASEAN–Korea FTA |
| European Union | 14.4% | 0% | GSP |
| USA | 1.5 cents/kg | Same (no FTA) | — |
Phytosanitary Requirements
Consistent requirements across most destination markets:
- Absence of Frankliniella occidentalis (Western flower thrips) — regulated in Japan, Korea and the EU
- Pesticide residues within MRL limits of the destination country
- Absence of soil and extraneous plant material
- Valid phytosanitary certificate issued by the Thai Department of Agriculture
Recommended Incoterms
For first-time buyers, CIF shifts cold-chain responsibility to the Thai exporter up to the destination port. Experienced importers often move to FOB Bangkok once they have preferred freight forwarders, giving more control over shipping costs and carrier selection.
Harvest to Taiwan airport: approximately 36–48 hours by airfreight. Harvest to Japan port by sea: approximately 5–7 days. Plan purchase orders around these windows to maximise remaining shelf life at destination.
Minimum Order Quantities
