How US kratom regulation actually works
No federal kratom statute exists, so authority sits with the states, and they have diverged into three very different postures.

Kratom is one of the hardest products to ship lawfully in the United States, and the reason isn’t that the rules are strict. It’s that there is no single rule at all.
Federal law left a vacuum
Kratom is not a federally controlled substance. The Drug Enforcement Administration announced its intention to schedule mitragynine and 7-hydroxymitragynine in 2016 and then withdrew the notice after public and congressional objection — an unusual retreat, and one that has shaped everything since. The Food and Drug Administration has never approved kratom for human consumption, has issued import alerts allowing detention of shipments without physical examination, and has warned against its use. But a federal agency declining to approve something is not the same as a federal law prohibiting it.
That distinction matters commercially. Because Congress never acted, the question of whether kratom may be sold fell to the states, and they answered it independently, at different times, for different reasons.
Three postures, not one spectrum
State responses have not arranged themselves neatly from permissive to restrictive. They fall into three groups that behave differently and require different things from a seller.
Outright prohibition. A handful of states classify kratom’s alkaloids as controlled substances. In these places the analysis is simple: no sale, no shipment, no exceptions for age or labeling. Several of these bans predate the modern kratom market and were passed as part of broader synthetic-drug legislation, which is why the statutory language sometimes reaches kratom without naming it.
The Kratom Consumer Protection Act model. A larger group adopted some version of a model bill drafted by industry advocates. The typical KCPA sets a minimum purchase age, requires specific labelling, bans sale of adulterated product, and caps the proportion of 7-hydroxymitragynine relative to total alkaloids. These states permit sale and regulate it, which is the posture most sellers find workable — but the details differ between them, and a product compliant in one KCPA state can be non-compliant in another because the alkaloid caps and labelling requirements are not uniform.
Silence. The largest group has no kratom statute at all. This is the category that causes the most trouble, because silence reads like permission and frequently isn’t. Where a state has not acted, counties and cities often have, and a shipment into a state with no law can still land in a city with a ban.
7-hydroxymitragynine is becoming its own question
The most significant recent movement isn’t about kratom leaf. It’s about concentrated 7-hydroxymitragynine products — semi-synthetic preparations far more potent than the plant material they derive from. Several states have moved on these separately from kratom itself, and some KCPA-style statutes already constrain them through alkaloid ratio limits.
For a seller this means the category question “do you sell kratom?” is no longer precise enough. A leaf powder and a 7-OH concentrate can face different rules in the same state.
What this means operationally
Three consequences follow, and they’re the reason kratom compliance is a recurring cost rather than a one-time project.
The destination governs. Legality is determined by where the package is going, not where your business sits or where your supplier is.
State-level answers are incomplete. In the silent states particularly, the local layer is where the actual prohibition often lives, and it changes on municipal timetables that nobody announces nationally.
The map moves. Legislatures amend, bans get repealed, KCPAs get adopted, and courts occasionally strike provisions down. A correct answer has a shelf life measured in months.
Where Gatekeep fits
We maintain the destination-by-destination rules behind all of this, including the local layer, and re-check each one against its primary source on a quarterly cycle. We don’t publish that library — it’s applied at checkout instead, so an order headed somewhere kratom is restricted simply doesn’t complete. What you get isn’t a document to maintain. It’s the enforcement.
