Pennsylvania, USA hemp laws: quick overview

Pennsylvania defines industrial hemp as Cannabis sativa L. with delta‑9 THC concentration not more than 0.3% on a dry‑weight basis, per 3 Pa.C.S. § 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 Department of Agriculture administers a permit system under the Controlled Plants and Noxious Weeds Act (3 Pa.C.S.A. § 1501 et seq.), requiring growers and processors to obtain a General Permit to cultivate, process, transport, or store hemp ([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)). Testing protocols require sampling by certified agents and analysis by DOA‑approved laboratories. Compliance is determined by total delta‑9 THC including measurement uncertainty; lots exceeding 0.3% must be remediated or destroyed. The acceptable hemp THC level is defined in the Pennsylvania State Hemp Plan (August 2025) ([ams.usda.gov](https://www.ams.usda.gov/sites/default/files/media/PennsylvaniaHempPlan.pdf?utm_source=openai)). The Department publishes lists of prohibited hemp varieties (tested above 1.0% THC) and varieties of concern (tested above 0.3%) that growers must avoid ([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)). Pennsylvania law explicitly prohibits delta‑8 THC (and other isomers) as controlled substances under 35 P.S. § 780‑102 and § 780‑104; possession, sale, or manufacture is prosecutable ([legis.state.pa.us](https://www.legis.state.pa.us/WU01/LI/TR/Transcripts/2023_0207_0002_TSTMNY.pdf?utm_source=openai)). Other cannabinoids like delta‑10, THCa, HHC are not specifically addressed and remain legally “unknown.”

Shipping guidance

Inbound shipments of hemp products are allowed provided the sender holds a valid PA Hemp General Permit and includes a certificate of analysis showing delta‑9 THC ≤ 0.3% dry weight. No state license is required for retail or wholesale distribution, but permit holders must maintain documentation per Articles VI–VII of the General Permit ([pa.gov](https://www.pa.gov/agencies/pda/plants-land-water/hemp/hemp-program-faqs?utm_source=openai)). Age verification is not specified for hemp products.

Testing & COA guidance

Hemp must be sampled by a certified sampling agent and tested by a DOA‑approved laboratory. Testing must report total delta‑9 THC with measurement uncertainty; compliance is determined if the range includes ≤ 0.3% ([ams.usda.gov](https://www.ams.usda.gov/sites/default/files/media/PennsylvaniaHempPlan.pdf?utm_source=openai)). Non‑compliant lots must be remediated or destroyed. The Department delays enforcement of DEA‑registered lab requirement per USDA rules ([pa.gov](https://www.pa.gov/agencies/pda/plants-land-water/hemp/hemp-program-faqs?utm_source=openai)).

What to buy

State‑legal hemp products include those derived from permitted hemp with delta‑9 THC ≤ 0.3% dry weight, including CBD extracts, fiber, seed, floral extracts, topicals, tinctures, and non‑intoxicating forms compliant with federal and state law ([pa.gov](https://www.pa.gov/agencies/pda/plants-land-water/hemp/hemp-program-faqs?utm_source=openai)).

What to avoid

Avoid delta‑8 THC products—they are explicitly illegal. Also avoid prohibited hemp varieties listed by PDA (e.g., Baux, Endo Cherry, Gorilla Glue, etc.) and varieties of concern due to THC 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)). Smokable hemp flower is taxable and may face scrutiny; edibles with CBD for human consumption are unlawful ([pa.gov](https://www.pa.gov/agencies/revenue/resources/tax-types-and-information/sales-use-and-hotel-occupancy-tax/cbd-and-hemp-products?utm_source=openai)).
