Thank you for your reply.
If you want the shipment by sea, I recommend you to use a refrigerated container. But the shipping rate by refrigerated container is more expensive than shipment by air for a small shipment.
I don't recommend you to use dry container shipment for the concern about the quality.
If you use EMS which is the cheapest shipping method by air, it will cost US$118 for 10kg.
So the total cost for 10kg of Matcha UJI (Regular) is US$517.
