Vermont: from farm to shop shelf, what the label has to show
Play it: a harvest lot moves through Vermont’s workflow on the left, and each required label piece snaps onto the package on the right, color-coded by who adds it.

The big idea: Vermont regulates the product as closely as the batch. Nothing reaches a shop shelf without a Board registration, the package has to be reusable and plastic-free, flower is capped at 30% THC and its lab result must sit within 20% of the label. Sampling is left to the licensee and labs may pool up to five cultivars for pesticides, but even a pesticide trace below the limit must be reported, and a remediated product has to say so on the label.

Step by step: Vermont
- Step 1: Harvest lot, numbered by the Board (Cultivator) A licensed cultivator records each harvest lot through forms on the Board’s online portal, which prefixes the license number (for example CLTV1234-001-001 for a process lot). One lot may mix several cultivars. This becomes the label’s process lot, the cultivator name and license and the harvested-on date.
- Step 2: The cultivator submits samples (Cultivator) The cultivator submits samples to a licensed lab with a form naming the process lot and strain; a COA without them cannot support a product registration. Each cultivar is tested on its own for potency and pathogens, but the lab may pool up to five cultivars for the pesticide screen.
- Step 3: Licensed lab (Testing laboratory) A Board-licensed lab, holding lab accreditation or certification under the Agency of Agriculture’s Cannabis Quality Control Program, tests smokable flower for potency, STEC, Salmonella and four Aspergillus molds, pesticides and water activity (0.65 or lower). The grow’s soil is tested for heavy metals every three years.
- Step 4: COA and potency (Testing laboratory) The COA unlocks the label’s potency, calculated as total THC (THC plus 0.877 × THCA, dry weight, two significant figures). The lab result may differ from the label claim by no more than 20%, and flower above 30% THC cannot be offered for retail sale.
- Step 5: Pass / fail (Cannabis Control Board) Licensees must report failures, and even quantifiable pesticide traces below the action limit, to the Board. Product adulterated with a food-crop pesticide may be remediated at most twice, and its label must then say so, with pre- and post-remediation results on any COA shown to consumers. Aspergillus-remediated cannabis may never be sold as flower.
- Step 6: Registered with the Board (Cannabis Control Board) Before a retailer may buy it, the product needs an active registration with the Board, filed by whoever puts it in its final form; bulk flower is registered by the retailer instead. Registration is how the Board checks the label, the packaging and the COAs.
- Step 7: Package + label (Cultivator) Consumer packaging must be reusable and not plastic, and child-deterrent for flower. The label carries the yellow CONTAINS THC triangle and the red NOT SAFE FOR KIDS octagon (each at least ½″), strain, variety, weight, potency, harvested-on and packed-on dates, a web address or QR code to the test results, and the Board’s full warning.
- Step 8: Retail sale (Retailer) The retailer checks the registration is active and sells to adults 21 and over. Bulk flower may be weighed out at the counter, up to 28 grams, into a reusable child-deterrent container, and retailers may take back packaging to sanitize and reuse.
Frequently asked questions
Who tests cannabis in Vermont?
A testing laboratory licensed by the Cannabis Control Board, which must hold current lab accreditation, or certification under the Agency of Agriculture's Cannabis Quality Control Program. Smokable flower is tested for potency, pathogens (STEC, Salmonella and four Aspergillus species), pesticides and water activity, with the grow's soil tested for heavy metals every three years; solvent extracts add residual solvents and heavy metals.
Who pulls the sample in Vermont?
The licensee. Vermont's rules and Board guidance have the cultivator or manufacturer submit samples to a licensed lab, with a form that must name the process lot and strain, or the COA cannot support a product registration. Each cultivar is tested alone for potency and pathogens; the lab may pool up to five for the pesticide screen, then must test each separately if any quantifiable pesticide appears.
What has to be on a cannabis label in Vermont?
Flower labels show the contents, the cultivator's name and license number, strain, variety, weight and potency, harvested-on and packed-on dates, the full process lot number, and a web address or QR code to the test results. Every package also carries the yellow CONTAINS THC triangle, the red NOT SAFE FOR KIDS octagon, KEEP OUT OF REACH OF CHILDREN and the Board's health warning.
Why is Vermont cannabis packaging not plastic?
Board Rule 2.2.9(b) requires packaging intended for consumer purchase at a retail location to be reusable and not plastic. The Board has waived the ban only for gaskets, seals and similar parts needed for health, safety or child-deterrence, and retailers may collect used consumer packaging, sanitize it and reuse it.
What is the THC limit for Vermont cannabis?
Flower offered for retail sale may not exceed 30% THC, and solid concentrates may not exceed 60%. Edibles must come in servings of 5 milligrams or less, up to 100 milligrams per package, and lab potency for flower must stay within 20% of what the label states.
