(a)
HDCP supplier licensees must sample and test each batch of product created from hemp
or hemp products for conformance with this rule. Once full panel testing required by this
RULES FOR SUPPLIERS AND WHOLESALERS OF HEMP-DERIVED
CHAPTER 0100-15
CANNABINOID PRODUCTS
rule is conducted on hemp or a hemp product, additional testing in downstream
commerce is not required except as provided:
1.
After the initial HDCP in commerce conforms to testing under subparagraph (a), if
a downstream HDCP supplier uses the product as an input to make a new HDCP
and during production of the new product the HDCP input underwent either a
chemical change (e.g. through exposure to heat or solvents) or a reconstitution
through addition or removal of other components, the supplier must cause each
batch of new HDCP to be sampled and tested for conformance with this rule.
2.
After the initial HDC product in commerce conforms to testing under subparagraph
(a), if a downstream HDC supplier uses the product as an input to make a new
HDC product but does not alter the chemical composition or formulation of the
HDC product compared to the input used (e.g. raw flower that is only physically
changed through cutting and filtering or bulk orders that are repackaged into
smaller units of like product), additional sampling and testing of the resulting
product batches are not required and prior test results in commerce of HDCs within
the product are presumptively valid. This part shall not limit the Commission’s
authority to test any cannabis products for compliance with the Act and this
chapter.
(b)
Prior to transport of any HDC product in commerce, HDC suppliers must confirm
conformance of the batch to all testing requirements under this rule.
(2)
Standards. Tolerances for each required testing analyte are listed below. Any test result
exceeding allowable limits is grounds for embargo, recall, remediation, or destruction of the
entire batch represented by the sample, regardless of whether the test result is discovered
through manufacturing testing or subsequent sampling and testing of retail HDC product.

but, at minimum, must include the product name and form, specific unique lot or batch number,
and net contents. While awaiting the COA, the remainder of the batch must be stored to prevent
degradation, adulteration, contamination, or mix-up until such time that the final packaging can
be applied.
(5)

request; and,
(xi)
Provide other information as required by the Commission.
(xii)
Registration is valid for two years from the date of approval.
3.
Failure to adhere to these requirements or requirements for issuance of COAs
under this rule is grounds for denial or revocation of any registration or
authorization issued by the Commission.
(b)
COAs.
1.
Third-party laboratories must include at a minimum the following on each COA
issued:
(i)
The laboratory’s name and address as it is registered with the Commission;
(ii)
The HDC product manufacturer’s name and address;
(iii)
Date the lab received the product sample for testing;
(iv)
The batch number and sample type represented by the sample;
(v)
Unique identifying information for the sample, if applicable;
(vi)
A photo and the state of the sample received (e.g. finished packaging). The
photo must clearly indicate the batch number on the product sample;
(vii)
Sample history including date received and date range of each test
conducted on the sample;
(viii) Analytical methods, limits of detection, limits of quantitation, and test results
for each analyte evaluated for the sample, regardless of whether the testing
conducted is required by this rule;
(ix)
Information about the testing method (e.g. name of the method, equipment
used, and date of last validation);
(x)
The result of the analysis for each type of analysis; a collective “pass”/“fail”
assessment for the entire batch that accounts for either passage of all or
failure of any one test conducted on the sample;
(xi)
Attestation of the validity of the test results via a signature from an authorized
representative, such as a laboratory director or quality assurance/quality
control team member, and date the certificate is issued;
(xii)
Date the COA was generated and reported; and
(xiii) Laboratory accreditation information.
2.
When reporting quantitative results, third-party laboratories must include in the
COA the corresponding units of measurement as required for tolerances under
this rule, as well as measurement uncertainties.
RULES FOR SUPPLIERS AND WHOLESALERS OF HEMP-DERIVED
CHAPTER 0100-15
CANNABINOID PRODUCTS
3.
A result of “< LOQ” for any analyte detected below the limit of quantitation (LOQ).
4.
A result of “ND” for any analyte that was tested for and not detected.
5.
Retention samples must be maintained under registered conditions for two years,
with access limited to laboratory personnel.
(c)
Failed Testing.
1.
Retesting. Any sample failure may be resubmitted as follows for confirmation of
testing failure.
(i)
If a reserve sample was retained by the same third-party registered
laboratory that produced the COA exhibiting a test failure, that laboratory
may retest the reserve sample following the failed test to confirm component
compliance. If a reserve sample was retained, the HDC manufacturer may
request a retest within seven (7) days of being notified of the failure.
(ii)
If the retested sample passes for the suspect component(s), a new sample
from the same batch must be drawn and submitted to a second third-party
registered laboratory for complete retesting of all components listed under
this rule. Retesting may not be performed at a laboratory under the same
ownership as the laboratory that performed the initial or a laboratory that
was subcontracted to complete the initial testing. If the second retesting
conforms to all required tolerances, the batch is deemed compliant with
testing requirements and may be transported and distributed in commerce.
(iii)
If a reserve sample is not available from the initial third-party registered
laboratory or if a sample fails either of the retests, the batch is deemed
nonconforming with regulatory requirements, and the batch must be held for
destruction or remediation.
2.
Remedy.
(i)
Microbial contaminants. An HDCP supplier is prohibited from transporting or
allowing transport of a batch that has failed microbial contaminant testing
unless:
(I)
The batch is further processed by a method that effectively sterilizes
the batch, is retested, and those test results show conformance with
required tolerances;
(II)
The supplier submits a corrective action plan to the Commission or
effective sterilization of the batch, receives written approval of the plan
from the Commission or,
(III)
The batch is rendered unusable.
(ii)
Over-concentrated product. An HDC product manufacturer is prohibited
from transporting or allowing transport of a batch that has failed THC
concentration testing unless:
RULES FOR SUPPLIERS AND WHOLESALERS OF HEMP-DERIVED
CHAPTER 0100-15
CANNABINOID PRODUCTS
(I)
The batch is further processed by a method that effectively dilutes the
batch, is retested, and those results show conformance with required
tolerances;
(II)
The manufacturer submits a corrective action plan to the Commission
or effective dilution of the batch, receives written approval of the plan
from the Commission or,
(III)
The batch is rendered unusable.
(iii)
For all other component testing failures, an HDCP manufacturer must render
the batch unusable prior to disposition.
3.
Testing Variance.
(i)
The measured cannabinoid content percentage for any product with a label
claim content must be within fifteen percent of the label amount for each
compound listed. If a wholesaler labels the package, the wholesaler must
label the HDCP with cannabinoid content that is listed on the COA. The
±15% variance only applies when HDCPs are labeled on the package prior
to the wholesaler taking possession for compliance testing.
