Exporting dried flowers to Japan requires strict compliance with the Plant Protection Act enforced by Japan's Ministry of Agriculture, Forestry and Fisheries (MAFF) [2][3]. Since August 5, 2023, Japan has implemented significantly stricter phytosanitary certificate requirements that affect a broad range of previously exempted plant-based products, including dried flowers [2].
The phytosanitary certificate serves as official proof that your dried flower products have been inspected and meet Japan's phytosanitary import requirements [3]. This requirement applies not only to commercial shipments but also to personal baggage and international mail, making it one of the most strictly enforced plant quarantine regimes globally.
Phytosanitary Certificate Requirements by Shipment Type
| Shipment Type | Certificate Required | Inspection Process | Processing Time |
|---|---|---|---|
| Commercial Import | Yes - Mandatory | Export country government inspection + Japan port inspection | 15-30 days validity |
| Personal Baggage | Yes - Mandatory | Declaration at arrival + port inspection | Immediate inspection on arrival |
| International Mail | Yes - Mandatory | Export country certificate + Japan quarantine inspection | May be held at customs until cleared |
For Southeast Asian exporters, the certificate application process typically involves contacting your national plant protection organization (such as the Department of Agriculture in your country). The inspection may include visual examination, laboratory testing for pests and diseases, and verification of treatment methods used during the drying process [4].
