Updated Pricing for US Customers
Matcha is now duty-free when entering the US. However, because shipments must still be sent DDP (Delivered Duty Paid) — you may still see a small amount of ‘Duties’ being charged at checkout. This is not a tariff, but simply a customs processing fee required for DDP shipments.
To make sure you don’t overpay, we’ve adjusted US prices 5% lower automatically. No code needed!
