Why COAs Are Non-Negotiable for Texas Hemp
Texas hemp buyers are flying blind without a Certificate of Analysis — a third-party lab document that tells you exactly what's in the product you're about to consume. At HighWay, every item on our shelves comes backed by a COA, because transparency isn't a selling point, it's the baseline.
A COA from an accredited third-party lab confirms cannabinoid potency and screens for pesticides, heavy metals, and residual solvents.
Texas law caps delta-9 THC at 0.3% dry weight — a COA is the only way to verify a product actually complies.
Batch numbers on packaging should match the COA exactly; if they don't, walk away from that product.
What a COA Actually Shows You
A Certificate of Analysis is a lab report issued by an ISO-accredited testing facility — not the brand, not the retailer. It breaks down cannabinoid percentages (CBD, delta-9 THC, delta-8, CBG, CBN, and more depending on the panel), and flags whether the product passed or failed screens for pesticides, microbials, heavy metals like lead and arsenic, and residual solvents left over from extraction. A full-panel COA is the gold standard. A potency-only COA tells you less than half the story, so always check what panels were actually run before assuming a product is clean.
Texas Hemp Law and the 0.3% Line
Under the Texas Hemp Program — authorized by House Bill 1325 — hemp products must contain no more than 0.3% delta-9 THC on a dry weight basis to be legal for sale and possession in the state. That number sounds small, but the difference between 0.28% and 0.31% is the difference between a legal product and a controlled substance under Texas law. A COA dated within the last 12 months and tied to the specific production batch is the only reliable way to confirm a product sits on the right side of that line. Brands that can't produce one on request are telling you something important about how seriously they take compliance.
How to Read a COA Before You Buy
Start at the top: confirm the testing lab is ISO/IEC 17025 accredited and that the report date is recent — ideally within the past six to twelve months. Find the batch or lot number and cross-reference it with the number printed on the product packaging. If they don't match, the COA is essentially useless for that specific product. Scan the potency panel for the delta-9 THC percentage and confirm it's at or below 0.3%. Then check the contaminant sections — each analyte should show a 'Pass' result or a detected level below the action limit. Any 'Fail' result or a missing contaminant panel is a hard stop. At HighWay, we keep COAs accessible in-store and can pull the document for any product you're considering.
Yes. Ask any of our staff and we'll pull the COA for whatever product you're looking at. We won't carry a product that can't produce one.
