Use the below chart to determine the minimum amount of sample needed to complete each test. Packaged products may require more than the labeled content if they are difficult to remove from packaging. (i.e. vape cartridges) 

For compliance testing, California has set minimum requirements of sample to be collected based on batch size or number of units of finished product in a batch. The amount of sample may be greater than the amounts in the table below. Samples for compliance testing must be collected by a laboratory employee in accordance with regulations.
