Industrial Hemp Plant Testing (Not Available in Louisiana)

Louisiana law requires all pre-harvest hemp testing to be conducted directly by the Louisiana Department of Agriculture & Forestry (LDAF). ACS Laboratory cannot perform official pre-harvest plant testing in the state. However, it offers plant and soil health and R&D test options.

Louisiana Pre-Harvest
Testing for Hemp Plants

Louisiana hemp growers must complete mandatory pre-harvest testing through the Department of Agriculture and Forestry before crop harvesting. State law requires official LDAF inspectors to collect samples from each field and verify that total delta-9 THC levels remain at or below 0.3% on a dry-weight basis. Harvest must occur within 30 days of sampling once the results confirm compliance.

To stay compliant, licensed growers should submit their planting and harvest reports on time, schedule sampling directly with LDAF, and wait for official approval before cutting or transporting plants.

ACS Laboratory does not conduct pre-harvest hemp testing in Louisiana. However, we support the industry by providing finished product compliance testing for hemp processors, brands, and retailers.

Need to Know

What is the turnaround time for hemp potency and safety tests?

ACS Laboratory typically delivers Louisiana five-panel tests in 5–7 business days after receiving samples. Expedited services are available for compliance-critical batches or product launches.

What products can ACS test for Louisiana compliance?

ACS tests hemp edibles, tinctures, beverages, topicals, and extracts for potency and purity to confirm compliance with LDH requirements.

What do Louisiana’s latest hemp rule updates mean for brands and testing?

Beginning January 1, 2025, Louisiana’s new hemp law (Act 752) introduces tighter controls on THC potency, packaging, and retail sales. Each serving of a consumable hemp product can contain no more than 5 mg of total THC, and packages are limited to 40 mg in total. Only consumers aged 21 and older may purchase these products.

For hemp brands, this means updated product formulations, relabeled COAs reflecting total THC, and continued compliance with the state’s required five-panel safety testing (cannabinoids, pesticides, solvents, heavy metals, and microbials).

What does Louisiana hemp compliance testing mean?

Compliance testing confirms hemp products meet Louisiana’s potency and safety standards. Each consumable hemp item must stay within the legal total THC limits and pass all required contaminant panels before retail sale.

Does ACS test industrial hemp plants in Louisiana?

No. The Louisiana Department of Agriculture & Forestry (LDAF) conducts all official pre-harvest sampling. ACS Laboratory only tests finished consumable products for compliance and quality assurance.

How do I start consumable hemp and CBD testing with ACS Laboratory?

Getting started is straightforward. Consumable hemp producers and sellers can contact the ACS team or call (561) 510-8396 for consultation. Once the appropriate testing panels are selected, ACS will provide sampling and shipping instructions.
