Industrial Hemp Plant Testing (Not Available in Texas)

Texas hemp growers must complete pre-harvest THC testing through a TDA-approved third-party lab and verify total delta-9 THC does not exceed 0.3% on a dry-weight basis. ACS Laboratory does not perform this service but offers plant health R&D testing to support cultivation performance.

Texas Pre-Harvest Testing for Hemp Plants

Texas law requires licensed growers to complete pre-harvest compliance testing through an approved laboratory. A TDA-licensed agent must collect representative plant samples within 15 days of harvest, which are analyzed to verify total delta-9 THC ≤ 0.3 % on a dry-weight basis. Laboratories must report results to TDA within 14 days.

01

Cannabinoid Potency

Matrix: Hemp Plants and Biomass

ACS Laboratory quantifies total delta-9 THC in pre-harvest hemp clippings using the formula Δ9-THC + (0.877 × THCA) on a dry-weight basis to determine compliance under TDA rules.

Texas Compliance Testing
for Consumable Hemp Extracts

Texas requires hemp producers to verify compliance at multiple stages—from raw plant material and extracted oils to finished consumable products. ACS Laboratory supports this full testing cycle with accredited potency and contaminant analysis, providing defensible results and digital COAs that ensure traceability and readiness for inspection. Our multi-phase approach helps brands maintain compliance, reduce product risk, and build consumer trust through verified quality at every step.

01

Cannabinoid Potency

Matrix: Flower/Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory tests hemp samples for 32 cannabinoids using HPLC-UV, far exceeding Texas’s baseline potency requirement. Results include total Δ9-THC, Δ8-THC, and minor cannabinoids such as CBDV, CBG, CBC, and CBN, reported with measurement-of-uncertainty to confirm compliance within the 0.3 percent THC limit.

02

HHCP & Hydrogenated Cannabinoids

Matrix: Hemp Derivatives, Edibles, and Beverages.

ACS Laboratory quantifies 9 hydrogenated cannabinoids, including HHC, HHCP, and H4-CBD, using LC-MS. This advanced profiling supports transparency for innovative hemp formulations that extend beyond the state’s minimum testing scope.

03

Residual Solvents

Matrix: Hemp Derivatives, Edibles, and Beverages.

ACS screens for 21 residual solvents using GCMS-HS to verify clean extraction and confirm no solvent residues remain. Although Texas rules only require confirmation of solvent absence, ACS quantifies each compound to strict safety benchmarks.

04

Pesticides

Matrix: Flower/Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory screens Florida hemp for 68 pesticides using LC-MS/MS and GC-MS, surpassing Texas’s general contaminant mandate. Each report documents non-detect levels and measurement-of-uncertainty data for DSHS compliance.

05

Heavy Metals

Matrix: Flower/Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory measures arsenic, cadmium, lead, and mercury via ICP-MS to verify concentrations remain well below nationally recognized limits. These results fulfill Texas’s heavy-metal screening requirement and support multi-phase ingredient testing.

06

Mycotoxins

Matrix: Flower/Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory tests for five mycotoxins—Aflatoxins B1, B2, G1, G2, and Ochratoxin A, providing toxin protection beyond Texas’s minimum contaminant categories.

07

Pathogenic Microbiology Microbiologyins

Matrix: Flower/Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory screens for Aspergillus species, Salmonella, and E. coli using Microarray SAE technology to confirm microbial safety.

08

Microbiology (qPCR)

Matrix: Flower, Plants, Derivatives, Edibles, and Beverages.

ACS Laboratory uses quantitative PCR to detect and measure total yeast and mold, ensuring microbial populations remain within acceptable limits before distribution.

Need to Know

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

In October 2025, the Texas Department of State Health Services enacted an emergency rule prohibiting the sale of consumable hemp products containing synthetic cannabinoids or more than trace THC to anyone under 21. This rule followed a failed legislative attempt to ban all hemp-derived psychoactive products. The emergency rule remains in effect while the state develops permanent restrictions on youth access and product safety.

‍

How long does hemp testing take?

ACS Laboratory typically delivers Texas compliance tests 5–7 business days after receiving samples. Expedited services may be possible for compliance-critical batches or product launches.

‍

Can I sell or manufacture hemp flower or vapes in Texas?

Licensed growers may cultivate hemp flower, but manufacturing smokable or inhalable hemp products is prohibited under state law. However, retailers may sell smokable hemp legally manufactured outside Texas under the 2022 DSHS v. Crown Distributing ruling.

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

Testing with ACS is simple. Consumable hemp growers, manufacturers, and sellers can contact the ACS team or call (561) 510-8396 for consultation. ACS provides sampling and shipping instructions once the appropriate testing panels are selected.

What stages of production require testing?

Texas law mandates testing at multiple phases—before processing, after extraction, and before products are sold. ACS supports this full cycle with validated methods and secure digital COAs to maintain compliance throughout manufacturing.

Does ACS Laboratory perform official Texas compliance testing?

Yes. ACS Laboratory is a Texas Department of Agriculture (TDA)–approved third-party lab, DEA-registered, and ISO/IEC 17025:2017 Accredited by A2LA. We provide compliant pre-harvest crop testing and consumable hemp product testing recognized by the state.

What does Texas hemp compliance testing mean?

Texas requires pre-harvest hemp crops to be tested for total delta-9 THC only. After processing, hemp ingredients and finished consumable products must undergo testing for potency and contaminants. Each batch must receive a Certificate of Analysis confirming total THC ≤ 0.3 percent.
