California, USA hemp laws: quick overview

California defines “industrial hemp” as Cannabis sativa L. with Δ9‑THC ≤ 0.3 % dry weight under Food & Agricultural Code §81000(a)(7), enforced via CDFA’s Industrial Hemp Program (effective ongoing) ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Assembly Bill 45 (2021, effective October 6, 2021) legalized hemp‑derived cannabinoids in foods, supplements, cosmetics, and topicals, provided they meet testing, labeling, and registration requirements under Health & Safety Code §111920 et seq. ([legalclarity.org](https://legalclarity.org/california-ab-45-industrial-hemp-rules-and-thc-limits/?utm_source=openai)). In response to proliferation of intoxicating hemp products, Assembly Bill 8 (2025, effective January 1, 2026) requires that any product containing intoxicating cannabinoids (e.g. Δ8, Δ10, THCA) be sold exclusively through licensed cannabis dispensaries under MAUCRSA, and bans synthetic cannabinoids in hemp retail; only CBD or CBN isolates > 99 % purity with no THC or synthetics are allowed in hemp food, beverage, or supplement products under H&S Code §111921.1 ([legalclarity.org](https://legalclarity.org/california-ab-45-industrial-hemp-rules-and-thc-limits/?utm_source=openai)).

Shipping guidance

Inbound shipments of compliant non‑intoxicating hemp products are allowed, but must include CDFA registration and lab test documentation. Intoxicating hemp products (e.g. Δ8) shipped into California are illegal unless via licensed cannabis dispensary; online shipments are subject to seizure and marketplace liability under SB 378 (effective July 1, 2026) ([cannabisregulations.ai](https://www.cannabisregulations.ai/state-legality/california-delta-8?utm_source=openai)).

Testing & COA guidance

CDFA requires pre‑harvest sampling and testing by USDA‑certified samplers per 3 CCR §§4890–4944; acceptable hemp THC level is ≤ 0.3 % Δ9‑THC accounting for measurement uncertainty ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Testing labs must be approved by CDFA ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/docs/IndustrialHempApplicationforTestingLaboratoryApproval.pdf?utm_source=openai)). Finished non‑intoxicating hemp products must include COA, meet AB 45 labeling/testing standards; intoxicating products sold via cannabis dispensaries follow MAUCRSA testing rules.

What to buy

Legal hemp products include non‑intoxicating CBD foods, beverages, dietary supplements, cosmetics, topicals, and pet products (excluding livestock feed) that comply with AB 45 testing, labeling, and registration. Hemp fiber and seed products also remain legal under CDFA rules.

What to avoid

Avoid hemp products containing intoxicating cannabinoids (Δ8, Δ10, THCA, HHC) unless sold through licensed cannabis dispensaries. Inhalable hemp products (vapes, smokable flower) are banned in hemp retail. Synthetic cannabinoids are prohibited in hemp products under AB 8.
