No specific import restrictions for personal kratom
Details
No specific import restrictions for personal kratom. Quantity guidance for United States: Personal use. Documentation: Certificate of Analysis (COA) showing THC content. Allowed status assumes personal-use quantities — commercial-scale amounts move the entry into formal import procedures with duty and documentation. Arrival checks are carried out by U.S. Customs and Border Protection (CBP); when in doubt use the declare (red) channel — declared goods at worst attract duty or surrender, while undeclared goods attract penalties. Leaving United States with kratom is a separate question: restricted — Kratom's legal status varies sharply — it is lawful in United States but controlled at many destinations, so treat cross-border carriage as high-risk.

Practical advice
United States permits personal-use Kratom within specified THC thresholds. Carry the manufacturer's Certificate of Analysis (COA) demonstrating THC content below the applicable threshold (typically 0.2% EU, 0.3% US 2018 Farm Bill, 0% for commercial products in Thailand under 2022 amended framework). Note that airport transit through third countries can trigger controlled-substance enforcement even where origin and destination both permit — verify transit-country rules.
