U.S. Hemp Rule Changes: What Canadian Businesses Should Know

When the U.S. federal government shutdown ended, the spending bill that reopened it introduced major regulatory changes for the American hemp sector. Most notably, the federal definition of hemp has been updated to measure total THC (including THCA), replacing the long-standing limit of ≤ 0.3% delta-9-tetrahydrocannabinol by dry weight. In addition, finished products may now contain no more than 0.4 mg of total THC per container.

These shifts are significant. Many hemp-derived products currently sold in the U.S., particularly those containing delta-8 THC, such as gummies and beverages, may no longer qualify as legal hemp and could instead be treated as controlled substances. Even non-intoxicating CBD products could be affected if their THC content exceeds the new threshold. U.S. state-level hemp programs may also be superseded where they are less strict than the new federal rules. 

Businesses across farming, manufacturing, and retail may face product reformulation, market withdrawal, or substantial economic loss, and the industry has 12 months to adjust to the new framework. Importantly, these changes target intoxicating or synthetically produced hemp-derived cannabinoids; traditional agricultural hemp for fibre, seed, and other non-intoxicating uses remains permitted under the existing Farm Bill.

What does this mean for Canada?

For Canadian companies, these U.S. changes do not automatically create new export opportunities for THC-containing products. Instead, they primarily restrict certain U.S. hemp-derived THC products. As a result, the new rules may disrupt U.S. hemp-THC competitors more than they open doors for Canadian exporters. Canadian businesses operating in hemp, CBD, and wellness markets should monitor the situation closely, as cross-border market dynamics continue to evolve over the coming year.
