Wisconsin hemp firms weigh options before Nov. 12 federal THC ban

What the federal change does

The appropriations law signed Nov. 12, 2025, rewrites the federal hemp definition effective Nov. 12, 2026. Under H.R. 5371, finished hemp products are capped at 0.4 milligrams of total THC per container, and cannabinoids synthesized outside the plant fall outside the definition.

Total THC includes THCA. That matters. It closes the gap that let delta-8 products, THC beverages and THCA flower ride on the 2018 Farm Bill's 0.3% dry-weight test.

NBC26's headline frames Wisconsin operators as weighing options. The signal doesn't attribute specific plans to any named business, and neither does this story.

Why Wisconsin is exposed

Wisconsin has no licensed adult-use or medical program, so hemp-derived THC has been the closest thing the state has to a legal market. Remove that, and the products that fill shelves in Wisconsin have no state-regulated substitute.

On a strict reading of the statute, a business holding inventory above the new cap has a finite set of paths:

• Sell through existing stock before the effective date.
• Reformulate to non-intoxicating CBD or sub-threshold products.
• Exit the category.
• Back a congressional delay or repeal.

Each carries cost. Reformulation requires new lab work and new labels, and sell-through assumes demand holds through a compressed window of about three weeks.

The 280E question nobody has answered

Hemp has stayed outside IRC §280E because it isn't a controlled substance, and the redefinition puts that treatment at risk for any product that falls out of it. Section 280E bars deductions and credits for businesses trafficking in Schedule I or II substances.

The statute doesn't address tax treatment. So the analysis falls back on the Controlled Substances Act, where 21 U.S.C. §802(16) defines marijuana by excluding hemp. A plant-derived product that no longer qualifies as hemp could, on a strict reading, be marijuana, while a synthesized cannabinoid raises a different question, since tetrahydrocannabinols are listed in Schedule I.

Neither reading is settled. Operators who priced margins on full deductibility should get written advice from tax counsel before filing, not after. Segregating inventory records by product type now will make any later allocation far easier.

The next signal: whether Congress moves a delay or fix before Nov. 12, and whether the DEA or IRS says anything about enforcement and tax treatment once the deadline passes.
