Kratom prohibited; penalties for import
Details
Kratom prohibited; penalties for import. Enforcement in United Kingdom carries fines from GBP 0 to GBP 0 and imprisonment up to 10 years in aggravated cases. Because kratom is prohibited rather than restricted, there is no permit route for an ordinary traveller — attempted import is treated as smuggling regardless of intent. Arrival checks are carried out by His Majesty's Revenue and Customs (HMRC); when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving United Kingdom with kratom is a separate question: prohibited — Kratom cannot lawfully be taken out of the United Kingdom — the Psychoactive Substances Act 2016 makes exporting and supplying it an offence, though simple possession is not criminal.

Practical advice
Do not carry kratom (Mitragyna speciosa), powder or leaf, into United Kingdom. UK Border Force treats it as a controlled substance with no personal-use permit; seizure plus prosecution is the standard response.
