Compliance Testing

Our regulatory compliant test panels meet the testing requirements for cannabis or cannabis products as required by the Cannabis Regulatory Agency (CRA), which includes a laboratory-performed sampling of a cannabis batch to ensure a representative sample is obtained. The laboratory staff member seals the batch and transports the sample back to the lab where the required tests are performed; the exact number of tests is determined by the type of sample being tested.

What is a compliance batch?

A compliance batch is a single unit of market-ready harvest cannabis or a manufactured product as defined within the regulations established by the CRA.

Cannabis Flower Batch Sizes

The weight of your harvest batch will determine the number of sample increments and the size of your test package. A harvest batch includes flowers, trim, eighth jars, leaf material, and kief.

Common Batch SizeIncrement MinimumMin Sample Size
10 lbs822.68 g
20 lbs1640.36 g
30 lbs2368.04 g
40 lbs2990.72 g
50 lbs34113.40 g
  • All sampling minimums are set by state, who requires that 0.5% be sampled for testing. To determine this for your particular batch, simply take the batch weight (in grams) and multiply by 0.005 to get an approximation of the minimum we are required to take.
  • We always require a minimum of 14 g to run full compliance tests, even if your ‘calculated’ weight is lower.

Cannabis Concentrate Batch Sizes

The weight of your Production Batch determines the number of Sample Increments (0.25 grams) to be included in your sample size. A concentrate product includes concentrates and cartridges.

Batch Size (lbs)Number of Sample IncrementsSample Size (g)
1 - 2123.00
2 - 3153.75
3 - 4184.50
4 - 10235.75
> 10297.25

Cannabis Infused Batch Sizes

The number of units in your production batch will determine the number of Sample Increments and the size of your Test Package. An infused product includes pre-rolls, edibles, and all other non-concentrate products not naturally produced by the cannabis plant.
