Rule 3. (1) A cultivator shall uniquely identify each immature plant batch with a single plant tag and record the information in the statewide monitoring system. Each immature plant batch must consist of no more than 100 immature plants.
(2) A cultivator shall tag each individual plant that is greater than 8 inches in height from the growing or cultivating medium or more than 8 inches in width with an individual plant tag and record the identification information in the statewide monitoring system.
(3) A cultivator shall separate the plants as the plants go through different growth stages and ensure that the plant tag is always identified with the plant throughout the growth span so that all plants can be easily identified and inspected. A cultivator shall ensure that identification information is recorded in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.
(4) After a tagged plant is harvested, it is part of a harvest batch so that a sample of the harvest batch can be tested by a licensed laboratory as provided in R 420.304 and R 420.305.

tested by a licensed laboratory as provided in R 420.304 and R 420.305. All
test results must indicate passed in the statewide monitoring system before the
marihuana is packaged. A marihuana product from harvest batches must not be
transferred or sold until tested, packaged, and tagged as required under
subrule (4) of this rule. A marihuana product from a harvest batch that fails
safety testing may only be sold or transferred under the remediation protocol
as provided in R 420.306. A marihuana product that fails testing and is

(6) A cultivator may transfer or sell marihuana to a
producer without first being tested by a laboratory in order to produce live
resinfresh frozen, or if the marihuana product will be refined to a
concentrate, with agency approval. After the producer has processed the

420.305. The agency may publish guidance for live resin fresh frozen and
concentrate production, transfer, and sale.
(7) After test results show a passed test and the harvest batch is packaged, the cultivator shall destroy the individual plant tags. Each package must have a package tag attached. A cultivator shall ensure this information is placed in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.
(8) A cultivator shall not transfer or sell any marihuana product that has not been packaged with a package tag attached and recorded in the statewide monitoring system in accordance with the acts, the marihuana tracking act, and these rules.

(10) After a package is created by a producer of the
marihuana product in its final packageform, the producer shall
have the sample tested pursuant to R 420.304 and R 420.305. The producer shall
not transfer or sell a final package marihuana product to a marihuana

with new samples consecutively to be eligible to proceed to sale or transfer. The
laboratory that reported the initial failing results shall not perform the
tests. If both samples pass, the batch is out of quarantine and eligible
for sale or transfer. If 1 or both samples fail, the marihuana product must
be destroyed as provided in these rules or remediated as described in subrule
(4) of this rule.
(3) A marihuana product is prohibited from being
retested if a final test for chemical residue failed pursuant to these rules.
If the amount of chemical residue found is not permissible by the agency, the
marihuana product is ineligible for retesting and remediation, and the product
