California, USA hemp laws: quick overview

California defines “industrial hemp” as Cannabis sativa L. or any part thereof with total THC (Δ9 + THCA) ≤ 0.3% dry weight, per Health & Safety Code § 11018.5, amended by AB 8 (Ch. 248, Stats. 2025), effective January 1 2026 ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)). Total THC includes Δ9‑THC and THCA, calculated per CDFA rules ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)). AB 8 (effective Jan 1 2026) prohibits sale of hemp flower, pre‑rolls, inhalable hemp products, intoxicating hemp edibles, beverages, and products containing synthetic cannabinoids or THC isolates; these are treated as cannabis ([cdph.ca.gov](https://www.cdph.ca.gov/Programs/CEH/DFDCS/Pages/FDBPrograms/FoodSafetyProgram/AssemblyBill8FAQ.aspx?utm_source=openai)). CDPH emergency regulations (DPH‑24‑005), effective Sept 24 2024, require zero detectable THC in industrial hemp products intended for human consumption and impose a minimum purchase age of 21 and a five‑serving limit per package ([cdph.ca.gov](https://www.cdph.ca.gov/Programs/CEH/DFDCS/Pages/FDBPrograms/FoodSafetyProgram/AssemblyBill8FAQ.aspx?utm_source=openai)).

Shipping guidance

Inbound shipments of unprocessed hemp (e.g., seeds, plant material) are allowed, subject to agricultural inspection and pest quarantine (CDFA FAQ) ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Processed hemp products with any detectable THC intended for human consumption are prohibited from sale; shipping such products into California would violate CDPH regulations and may result in enforcement by ABC ([abc.ca.gov](https://www.abc.ca.gov/enforcement/illegal-hemp-enforcement/?utm_source=openai)). No special age verification or retailer registration for shipping unprocessed hemp; but intoxicating hemp products cannot be sold or shipped into the state.

Testing & COA guidance

Cultivators must obtain a lab test report indicating THC percentage prior to harvest (FAC § 81006(e)) ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Testing must follow 3 CCR § 4890 definitions and methods, including post‑decarboxylation or conversion formula, and apply measurement of uncertainty for pass/fail (3 CCR § 4890, § 4944(b)(18)) ([cdfa.ca.gov](https://www.cdfa.ca.gov/plant/industrialhemp/faq.html?utm_source=openai)). Labs must be registered and follow CDFA protocols; COA retention implied. No explicit ISO 17025 requirement stated in sources.

What to buy

Allowed: industrial hemp in raw agricultural form (seeds, stalks, fiber, oil/cake from seeds) with total THC ≤ 0.3% dry weight, for non‑human‑consumption uses (e.g., textiles, construction, non‑cannabinoid extracts) ([law.justia.com](https://law.justia.com/codes/california/code-hsc/division-10/chapter-1/section-11018-5/?utm_source=openai)).

What to avoid

Avoid: hemp flower, pre‑rolls, inhalable products (vapes, cartridges), intoxicating edibles, beverages, dietary supplements, cosmetics with THC, synthetic cannabinoids, THC isolates — all banned as of Jan 1 2026 under AB 8 and CDPH regs ([cdph.ca.gov](https://www.cdph.ca.gov/Programs/CEH/DFDCS/Pages/FDBPrograms/FoodSafetyProgram/AssemblyBill8FAQ.aspx?utm_source=openai)).
