U.S. exports of tetrahydrocannabinols (all isomers) (HS 293295) totaled $645K in June 2026, traded with 1 country.
Tetrahydrocannabinols (THC), covering all isomers including delta-8, delta-9, and delta-10 forms, occupy a uniquely complex regulatory position: delta-9-THC remains a Schedule I controlled substance under the Controlled Substances Act, while certain hemp-derived isomers occupy contested legal territory following the 2018 Farm Bill. All imports under 2932950000 are subject to DEA scrutiny, and CBP will examine documentation closely to determine whether the material meets the statutory definition of hemp (delta-9-THC concentration at or below 0.3% on a dry-weight basis) or constitutes a controlled substance. Switzerland and Canada are the recorded US import sources under this heading, consistent with their roles in pharmaceutical cannabis research and licensed cannabinoid manufacturing. Admissibility determinations are highly fact-specific; consult a licensed customs broker and legal counsel before importing any THC isomer.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
CBP relies on laboratory testing, certificates of analysis, and accompanying documentation to verify that the delta-9-THC concentration does not exceed the 0.3% dry-weight threshold established under the 2018 Farm Bill. Shipments lacking credible third-party lab results or originating from non-licensed facilities are likely to be detained for further examination or refused entry.
The legal status of delta-8 and delta-10 THC isomers is actively contested. The DEA's position is that synthetically derived THC isomers — including those converted from hemp-derived CBD — remain Schedule I substances regardless of the Farm Bill hemp exemption. Importers of any THC isomer should obtain a formal ruling or legal opinion before shipment, as enforcement posture can change.
