The law is written in milligrams.Most labels are not.
Section 781 of P.L. 119-37 sets a cap of 0.4 mg of total THC per package, effective November 12, 2026. A per-package cap does not scale with serving size — it measures the whole container at once. Enter the numbers from your certificate of analysis and see where a single bottle lands.

Logarithmic scale. Each tick is a different order of magnitude.
| Total THC = Δ9-THC + (THCA × 0.877) | 2.000 mg/mL |
|---|---|
| Per package | 60.000 mg |
| Federal cap | 0.400 mg |
| Highest concentration that fits the cap | 0.0133 mg/mL |
| Reduction needed | 99.33% |
Per package, not per serving
Serving size is not a lever here. Splitting a bottle into more droppers changes the dose on the label but not the number this cap measures.
Percent hides the problem
A concentration that reads as a small percentage can still be a large number of milligrams once it is multiplied across a full container.
What is still unsettled
FDA has not published its definition of “container,” and a partial one-month delay passed the Senate but has not become law. The date on the books is November 12, 2026.

This tool performs arithmetic on numbers you provide. It does not verify your certificate of analysis, interpret the statute, or constitute legal advice. Total THC is calculated as Δ9-THC plus THCA multiplied by 0.877, the molar conversion factor for decarboxylation. Confirm any compliance decision with qualified counsel and a validated laboratory result.
