Each lesson is written and reviewed before publication. Here is what this path works through.

  • Explain what a COA is and why every product needs one
  • Know the 12 items Texas rules require on a COA
  • Match a COA to the physical product in front of you
  • Spot the red flags that mean 'don't shelve this'
  • Name the one number that decides hemp legality in Texas today — total delta-9 THC — and say why 'total THC' is a different number
  • Apply the rule's conversion — total delta-9 THC = (0.877 x THCA) + delta-9 THC — to real COA values
  • Read the measurement-of-uncertainty range the way the rule does, including the rule's own 0.35% example
  • Spot products that pass on delta-9 alone but fail once THCA is counted
  • Answer 'do COAs expire?' with the exact Texas rule, not folklore
  • Know what §300.301(f) requires when a COA expires — and what it leaves open
  • Tell COA expiration apart from batch dates and ingredient use-by dates
  • Run COA expiry as a calendar discipline across your whole inventory
  • Define 'lot' and 'batch' the way the Texas rules do — and know they're the same thing
  • Explain why the batch number on a label must match the lot number on its COA
  • Know which lot records the rules require, who keeps them, and for how long
  • Run intake and inventory so every unit on your shelf traces to a matching COA
  • Know who in your supply chain needs which Texas credential — and how to check a supplier against DSHS's public licensee list before the first order
  • Run the COA Intake Checklist on every delivery, one lot at a time
  • Spot-check the label's required elements and warnings at receiving, before shelving
  • Verify the packaging duties that sit on you at the time of sale
  • Handle out-of-state product, incomplete paperwork, and rejections without guessing where the rules are silent

The path, step by step

Lessons in recommended order. Each step shows whether it is published and whether you have finished it on this device.

  1. Step 1 of 5Published — not startedUnderstanding COAsWhat a Certificate of Analysis actually says, the 12 things Texas requires on it, and the red flags that should stop a product at the door.
  2. Step 2 of 5Published — not startedTotal Delta-9 THC MathWhich THC number decides legality in Texas today, the 0.877 conversion straight from the rule, worked examples you can redo on a calculator, and why a product that passes delta-9-only math can still fail.
  3. Step 3 of 5Published — not startedCOA Expiration & RetestingDo hemp COAs expire in Texas? Yes — and the rule says exactly what that means. What §300.301(f) requires when a COA expires, what retesting involves, and how to run expiry dates as a calendar discipline instead of an inspection surprise.
  4. Step 4 of 5Published — not startedLot & Batch TraceabilityWhat a lot actually is under the Texas hemp rules, why the batch number on the label has to match the lot number on the COA, and how lot identity runs through records, inspections, and recalls.
  5. Step 5 of 5Published — not startedReceiving Products From VendorsThe operational intake lesson: what a Texas hemp retailer checks before a delivery goes from the back door to the shelf — the vendor, the paperwork, the COA, the label, and the packaging — and what to do when something doesn't clear.
