The most common assumption we hear about November is that compliant material stays compliant. For anything carrying cannabinoid content, that is not how a definitional change works.
What changed in the test
Section 781 of Public Law 119-37 defines hemp by:
“a total tetrahydrocannabinols concentration (including tetrahydrocannabinolic acid) of not more than 0.3 percent on a dry weight basis”
The former federal test measured delta-9 THC. The new one measures total tetrahydrocannabinols with THCA named in the statute. Effective 12 November 2026.
Why existing certificates do not carry over
A COA answers the question it was asked. If yours report delta-9 against 0.3 percent, they are accurate, complete, and about to be answering a question that is no longer the legal one.
Material that passed at, say, 0.2 percent delta-9 while carrying meaningful THCA will not pass a total-THC test. Nothing about the material changed. The arithmetic did.
The practical exposure is that a quality file which looks complete may contain no evidence at all about the standard you will be held to.
The method questions that now decide the answer
Three things that were technical footnotes and are now determinative.
Does the method report THCA separately? If it does not, you cannot compute a total. Some panels report only decarboxylated values, some only acid forms, some both.
What conversion factor is applied? Totalling THCA and delta-9 is not simple addition, because the molecules differ in mass. Labs apply a conversion factor when calculating total THC. Two labs can analyse identical material and report different totals depending on their approach.
How wide is the panel? The finished-product cap covers a combined total including other cannabinoids with similar or similarly marketed effects. A THC-only panel cannot answer that question. Reading a chromatogram properly matters here, and our note on what GC-MS data actually tells you applies the same discipline to the aromatic side.
What to ask your lab
Do you report total THC including THCA, and what conversion factor do you apply? Can you issue certificates stating compliance against the amended definition specifically? What is your turnaround at volume between now and November, given every hemp client will ask at once?
That last question is not administrative. Lab capacity is a finite resource with a queue, and the queue forms in September.
What to ask your suppliers
Which standard do your COAs report against today? Will you issue total-THC documentation before November, and from which lot? What residual cannabinoid content does this material carry, as a number rather than “negligible”?
If a supplier cannot answer the third question with a figure, that is itself the answer. The wider framework for this sits in the 12-point supplier checklist, and the documentation layer in COA, SDS and TDS.
A note on seed and genetics
The amended definition also excludes “any viable seeds from a Cannabis sativa L. plant that exceeds a total tetrahydrocannabinols concentration (including tetrahydrocannabinolic acid) of 0.3 percent in the plant on a dry weight basis”.
Anyone holding genetics inventory should apply the same re-testing logic there. Compliance under the previous standard is not evidence of compliance under this one.
Timing
Testing turnaround, supplier response and packaging changes each run on their own clock. The Senate text released 2 August 2026 that would move most restrictions to 11 December had not passed as of 5 August. A four-week extension does not create lab capacity.
About this brief
Written 3 August 2026 and checked against the statute and the Federal Register rather than against secondary coverage. This is a summary for commercial planning, not legal advice.
