Is Tianeptine Legal In The U.S. State And Federal Guide

Disclaimer. This article is for informational and educational purposes only and is not legal advice. Nordic Chems supplies tianeptine strictly for laboratory research. It is not for human consumption. Laws change, so confirm current rules with your state authorities and your institution's compliance office before you order or handle any research chemical.

Tianeptine is not a federally controlled substance as of October 13, 2026. That status is under review: on July 8, 2026, the DEA proposed placing tianeptine in Schedule I of the Controlled Substances Act (CSA), and the comment period closed on August 7, 2026. No final rule has been published. At the state level, 22 states have scheduled tianeptine and Maryland bans its retail sale. The FDA has not approved tianeptine for any medical use.

For a research lab, that means 2 checks before every order: the federal rule in force that day, and the law of the state where the material will be received and stored.

What Is Tianeptine?

Tianeptine is a synthetic tricyclic chemical first developed in France in the 1960s. Research suppliers list it in 2 salt forms, tianeptine sodium and tianeptine sulfate. Laboratory work with tianeptine centers on glutamatergic signaling, including AMPA and NMDA receptor activity, on synaptic plasticity, and on mu-opioid receptor pharmacology.

That last property drives most of the regulation. The DEA's May 2026 tianeptine fact sheet states that tianeptine "binds to and activates mu-opioid receptors." State and federal scheduling actions focus on that activity and on reports of misuse of tianeptine products sold to consumers.

Is Tianeptine a Federally Controlled Substance?

No. The DEA's May 2026 fact sheet says: "Tianeptine is not federally controlled under the Controlled Substances Act." That is still true on the date of this update. Federal status has 3 moving parts: a pending DEA rule, FDA enforcement, and bills in Congress.

The DEA's July 2026 Schedule I Proposal

On July 8, 2026, the DEA published a notice of proposed rulemaking (91 FR 42150, Docket No. DEA-1596) to place tianeptine in Schedule I. The proposal covers tianeptine and its salts, isomers, esters, and ethers, so tianeptine sodium and tianeptine sulfate both fall inside it. It follows a July 2025 recommendation from the U.S. Department of Health and Human Services that tianeptine be placed in Schedule I.

Public comments closed on August 7, 2026. A proposed rule does not change the law. Tianeptine becomes a federal Schedule I substance only if the DEA publishes a final rule, and only from that rule's effective date. We searched the Federal Register on October 13, 2026 and found no final rule.

What a Final Rule Would Require of Research Labs

The proposal lists what would apply to anyone who handles tianeptine once a final rule takes effect:

• DEA registration. Every person or facility that handles tianeptine would need a DEA registration, and research would need a Schedule I researcher registration.
• A 90-day window for existing Schedule I researchers. Researchers already registered for another Schedule I substance could continue tianeptine research if they apply within 90 calendar days of the final rule.
• Stock transfer. Anyone unable or unwilling to register would have to transfer tianeptine stock to a DEA-registered person before the effective date.
• Security, inventory, and records. Schedule I security rules, an initial inventory followed by a new inventory every 2 years, and DEA recordkeeping would apply.

Bills in Congress

The 119th Congress has at least 2 House bills that name tianeptine. H.R. 3520, the STAND Against Emerging Opioids Act, was introduced in May 2025 and would place tianeptine in Schedule III by statute. H.R. 7407, the Prohibiting Tianeptine and Other Dangerous Products Act of 2026, was introduced on February 5, 2026 and would amend the FD&C Act to add prohibited acts for products sold under a dietary label that do not meet the statutory definition for that category. A bill changes nothing until it is enacted.

What Does the FDA Say About Tianeptine?

The FDA's position is separate from DEA scheduling, and it already applies. The agency states that tianeptine is not approved for any medical use in the U.S. It also concludes that tianeptine "does not meet the statutory definition of a dietary ingredient and is an unsafe food additive," which makes consumer products that contain it adulterated under the FD&C Act. Tianeptine is authorized as a prescription product in some other countries. That has no effect on its U.S. status.

FDA enforcement has targeted companies that sell tianeptine to consumers:

• Warning letters to sellers in November 2018, May 2021, and February 2022
• A January 2024 letter urging retailers to stop selling Neptune's Fix and other tianeptine products
• A May 8, 2025 letter alerting health care professionals to tianeptine product trends

The FDA reports that poison control cases involving tianeptine rose from 11 in total between 2000 and 2013 to 151 in 2020 alone.

For a lab, the practical point is labeling and intent. Research material has to stay research material: labeled for laboratory use, sold without any health claim, and handled only by trained personnel.

Which States Restrict Tianeptine?

As of October 13, 2026, 22 states list tianeptine on a controlled substance schedule, and Maryland prohibits retail sale without scheduling it.

The Legislative Analysis and Public Policy Association's December 2025 tianeptine fact sheet documents 20 of the scheduled states and Maryland's April 2024 retail ban. The other 2 states acted in 2026:

• New Jersey. A law signed in January 2026 (S-729/A-4814) makes tianeptine a Schedule II controlled dangerous substance.
• Connecticut. State regulators placed tianeptine in Schedule I and gave businesses until March 25, 2026 to return or destroy products.

More states have bills pending. In Pennsylvania, H.B. 377 passed the House 200 to 2 on June 15, 2026 and was referred to the Senate Judiciary Committee on June 18, 2026. Bills were also introduced in California, New York, and Maine during 2025. Our state-by-state list of tianeptine restrictions covers each state in more detail.

What a State Schedule Means for a Lab

State schedules do not mirror each other, and they apply regardless of federal status. In a state that schedules tianeptine, possessing it without the state authorization that schedule requires can be a criminal offense, including for research. A "research use only" label does not create an exemption. Registration rules and penalties differ by state and by schedule, so confirm them with your state's board of pharmacy or controlled substances authority and your institution's compliance office.

Our shipping profiles keep tianeptine from going to restricted states. The "Regulated States" section on each product page shows the current list: Tianeptine Sodium powder, Tianeptine Sodium capsules, Tianeptine Sodium solution, and Tianeptine Sulfate capsules. If your state is listed, we can't sell to you.

How to Check Tianeptine's Legal Status Before You Order

Run these 7 checks before each purchase or transfer. Our guide to the legal requirements for tianeptine procurement goes deeper on documentation.

1. Check the federal rule in force. Search the Federal Register for a final DEA rule on tianeptine. The proposed rule is Docket No. DEA-1596.
2. Check your state schedule. Look up your state's current controlled substance schedules and any pending bill. If material moves between sites, check every state involved, plus any county or city rule.
3. Get compliance sign-off. Ask your institution's compliance or environmental health and safety office to confirm the purchase is allowed, and keep that confirmation on file.
4. Verify the supplier. Ask for a batch-specific certificate of analysis (COA) and a safety data sheet (SDS). Nordic Chems publishes independent third-party test results for its batches.
5. Keep the label intact. Containers should read "For Research Use Only" and "Not for Human Consumption," with no health or performance claim on the label or paperwork.
6. Brief your team. Everyone who handles the material should know its legal status in your state, plus your handling, storage, and disposal procedures.
7. Keep records. File purchase invoices, the COA, the SDS, experimental protocols, and storage and disposal logs. If federal scheduling takes effect, an initial inventory will be required.
