Kratom is legal in Puerto Rico. The territory does not list kratom, mitragynine, or 7-hydroxymitragynine as controlled substances, and no local ordinance bans its sale, possession, or personal use. Two things sit alongside that legality and are worth knowing before you buy: a consumer protection bill that passed the Puerto Rico Senate in May 2025, and active federal enforcement that targets kratom shipments and certain concentrated products.
What Legal Means Right Now
Adults in Puerto Rico can walk into a retail store and buy kratom, order it online from mainland vendors, and keep it for personal use without a permit. Retailers do not need a territorial license to sell it. There are no current labeling, testing, or age-verification mandates under Puerto Rico law.
Federal law lines up with that status for now. Kratom is not scheduled under the Controlled Substances Act, though the DEA lists it as a “Drug and Chemical of Concern,” a designation that carries no criminal penalty on its own but signals continued monitoring.1Drug Enforcement Administration.

The Pending Kratom Consumer Protection Act
On May 8, 2025, Puerto Rico’s Senate passed Proyecto del Senado 108, the “Ley para la Protección del Consumidor de Kratom de Puerto Rico.”2Microjuris. P. del S. 108 – Ley para la Proteccion del Consumidor de Kratom de Puerto Rico The bill would not ban kratom. It would regulate how it is made, labeled, and sold. If signed, it would:
- Prohibit selling kratom mixed with dangerous non-kratom substances, poisons, or any controlled substance.
- Limit residual solvents in extracts to USP 467 levels.
- Cap 7-hydroxymitragynine at 2% of a product’s total alkaloid content.
- Ban synthetic mitragynine, synthetic 7-hydroxymitragynine, and other synthetically derived kratom compounds.
- Require adequate directions for safe use on every product, including a recommended serving size.
- Prohibit sales to anyone under 21.
Penalties come in two tiers. Product-quality violations under Article 3 would carry administrative fines of up to $500 for a first offense and up to $1,000 for repeat violations. Selling kratom to someone under 21 would be a misdemeanor, with fines up to $5,000 or up to six months in jail.2Microjuris. P. del S. 108 – Ley para la Proteccion del Consumidor de Kratom de Puerto Rico The bill has not yet been signed into law, so none of it is enforceable today.
Federal Import Enforcement
Because virtually all kratom sold on the island arrives by air or sea, federal agencies have a natural chokepoint. The FDA does not recognize kratom as a lawful dietary supplement. Under Import Alert 54-15, field offices can detain kratom shipments without physical inspection when the shipper appears on the agency’s red list, and shipments from unlisted companies can be flagged for review and added to it.3U.S. Food and Drug Administration.

Concentrated 7-OH Products
In July 2025, the FDA issued warning letters to seven companies selling products containing isolated 7-hydroxymitragynine. The agency stated that 7-OH “is not a lawful dietary supplement, food additive, or ingredient in any approved drug” and that marketing any product containing it is illegal.4U.S. Food and Drug Administration. FDA Issues Warning Letters to Firms Marketing Products Containing 7-Hydroxymitragynine Traditional kratom leaf naturally contains small amounts of 7-OH; the enforcement targets concentrated or isolated 7-OH products, such as shots and tablets marketed by that name. Those face the highest federal enforcement risk regardless of Puerto Rico’s territorial rules.
Service Members Stationed in Puerto Rico
Kratom’s territorial legality does not reach military personnel. In September 2025, the Department of Defense issued a memorandum declaring kratom use a violation of the Uniform Code of Military Justice effective December 31, 2025. The Navy formalized its own ban on January 14, 2026, prohibiting all sailors and Marines from using, possessing, distributing, or manufacturing any product containing kratom, mitragynine, or 7-hydroxymitragynine.5MyNavyHR. ALNAV 003/26 – Prohibition of the Use of Kratom, Mitragynine and 7-Hydroxymitragynine Products
The ban applies regardless of local law and covers naturally derived, semi-synthetic, and synthetic forms at any concentration. Violations can be prosecuted under Article 92 of the UCMJ (failure to obey a lawful order), which can include court-martial. Narrow exceptions exist for law enforcement activities, authorized medical personnel, and genuinely unknowing consumption. Deliberately avoiding knowledge of a product’s contents is not a defense.5MyNavyHR. ALNAV 003/26 – Prohibition of the Use of Kratom, Mitragynine and 7-Hydroxymitragynine Products Standard federal workplace drug panels for civilian employees do not currently test for kratom alkaloids, but individual agencies can set their own protocols.
Flying With Kratom
Flights between the mainland and Puerto Rico are domestic, so there is no customs inspection. Kratom is legal federally and locally, and carrying it on a domestic flight is not itself a crime. The friction point is TSA screening. Powders are allowed in both carry-on and checked bags, though TSA recommends checked luggage for convenience. Powder containers larger than 12 ounces in a carry-on may draw additional screening, and if the screener cannot resolve the substance at the checkpoint, it will be confiscated.6Transportation Security Administration. What Is the Policy on Powders? Are They Allowed?
Keep kratom in its original labeled packaging. An unmarked bag of green powder invites questions. If you connect through Alabama, Arkansas, Indiana, Vermont, Wisconsin, or Rhode Island, kratom is banned in those states, and possession during a layover could create legal exposure even though airport enforcement is uncommon.
What Could Change the Answer
The DEA announced its intent in 2016 to temporarily place mitragynine and 7-hydroxymitragynine into Schedule I, then withdrew the proposal after public backlash. Kratom remains on the DEA’s list of “Drugs and Chemicals of Concern.”1Drug Enforcement Administration. Kratom Federal scheduling would override Puerto Rico’s territorial position and turn possession into a federal crime. A federal Kratom Consumer Protection Act (S. 3039) was introduced in the 118th Congress to build a national regulatory framework, but it did not advance. Until either the territorial bill is signed or federal law shifts, kratom sits in a gap between legal on the island and skeptical treatment from federal regulators.
