The 0.050% Threshold: How the DEA's 7-OH Scheduling Rule Decides Which Kratom Products Become Illegal

Why it matters

The specific 0.050% dry weight threshold in the DEA's scheduling notice determines which kratom products remain legal and which become Schedule I. The public comment window closes July 31 — clinicians, researchers, and affected consumers can still submit evidence to docket HHS-OASH-2026-0232.

The big picture

When the DEA moved to temporarily schedule 7-OH on July 1, 2026, most coverage focused on the headline ban. Less noticed: the exact threshold defining which products are covered is still open for public comment through July 31. That threshold — 0.050% 7-OH by dry weight for botanical products, or more than 1.00 mg for synthetic ones — largely protects natural leaf kratom while targeting concentrated products. HHS will pass submitted comments to Acting Attorney General Todd Blanche, who makes the final scheduling decision.

Key findings

• Natural kratom leaf typically falls below the 0.050% 7-OH threshold; most concentrated 7-OH products sold at retail sit well above it
• 7-OH acts on the same brain receptors as morphine but is substantially more potent than the main kratom alkaloid mitragynine
• Companies concentrate trace 7-OH to levels the natural leaf never reaches, then sell it as kratom — following the same regulatory loophole pattern used by synthetic nicotine and novel supplement makers
• Established kratom trade groups including the American Kratom Association and Global Kratom Coalition lobbied for 7-OH scheduling, arguing concentrated products harm the legitimacy of natural leaf kratom
• Public comments accepted at regulations.gov docket HHS-OASH-2026-0232 through July 31, 2026

What they say

"Prescription opioids were sold as safe when they weren't, and by the time the labels caught up, people were already dependent or dead. 7-OH is a potent opioid sold as 'just kratom,' and most people buying it don't know how strong it is," wrote Dr. Céline Gounder, physician and public health journalist.

Bottom line

The DEA's 7-OH scheduling proposal hinges on a single threshold — 0.050% dry weight — and the public comment period to challenge or support that line closes July 31, 2026.
