Pennsylvania, USA hemp laws: quick overview

Pennsylvania defines industrial hemp as Cannabis sativa L. and any part of the plant with delta‑9 THC concentration not more than 0.3% on a dry weight basis, per 3 Pa.C.S.A. § 703 and the PA Hemp General Permit effective February 11, 2023 ([legis.state.pa.us](https://www.legis.state.pa.us/WU01/LI/LI/CT/HTM/03/00.007..HTM?utm_source=openai)). The General Permit, under the Controlled Plants and Noxious Weeds Act (3 Pa.C.S.A. § 1501 et seq.), regulates cultivation, processing, transport, and requires permittees to submit to testing and sampling protocols ([pa.gov](https://www.pa.gov/content/dam/copapwp-pagov/en/pda/documents/plants_land_water/hemp/documents/2023%20Hemp%20General%20Permit%2C%20signed%202-1-23.pdf?utm_source=openai)). The USDA‑approved state plan clarifies that compliance is determined by total delta‑9 THC plus measurement of uncertainty including 0.3% ([ams.usda.gov](https://www.ams.usda.gov/sites/default/files/media/PennsylvaniaHempPlan.pdf?utm_source=openai)). Hemp varieties that have tested above 1.0% total THC are designated “Prohibited Varieties” and must not be planted or distributed; those above 0.3% but below 1.0% are “Varieties of Concern” and carry higher risk ([pa.gov](https://www.pa.gov/content/dam/copapwp-pagov/en/pda/documents/plants_land_water/hemp/documents/2025%20varieties%20of%20concern%20and%20prohibited%20varieties.pdf?utm_source=openai)).

Shipping guidance

Inbound shipments of hemp are allowed provided the sender holds a valid PA Hemp General Permit and shipments are accompanied by a COA showing compliance with the 0.3% delta‑9 THC limit including measurement of uncertainty. There is no state‑specific age verification requirement for hemp shipments. Retailers must be permit‑holders; unpermitted processing or sales (e.g., of delta‑8) may result in prosecution.

Testing & COA guidance

Testing must be conducted by laboratories approved by the PA Department of Agriculture under the Hemp Testing Laboratory Registry. Samples must include a certificate of analysis with delta‑9 THC concentration and measurement of uncertainty. If a lot exceeds 0.3% THC, remediation or destruction is required. Enforcement of DEA‑registered lab requirement is delayed per USDA guidance ([pa.gov](https://www.pa.gov/agencies/pda/plants-land-water/hemp/hemp-program-faqs?utm_source=openai)).

What to buy

Products derived from hemp with delta‑9 THC ≤ 0.3% dry weight, including CBD extracts, oils, tinctures, topicals, fiber, seed, and non‑intoxicating derivatives, from permitted growers/processors.

What to avoid

Delta‑8 THC products are illegal under PA law and should be avoided. Hemp varieties testing above 0.3% THC (especially Prohibited Varieties above 1.0%) are banned. Smokable hemp flower is taxable and regulated; ensure compliance. Other cannabinoids (delta‑10, HHC, THCa) are not specifically addressed and remain legally uncertain.
