WHY IT MATTERS
Transparency isn’t an add-on.
A certificate of analysis only means something if it’s tied to the exact lot in your hands. That’s why every COA in our library is searchable by product and lot number, not buried in a generic download.
The COA Library page reflects Certificates of Analysis for our current, active batches. If you are seeking a COA for a previous batch or lot that is no longer listed, please contact us directly at admin@rainiercompounds.com with the product name and lot number, and we will provide the documentation on request.
We typically respond within 1 to 2 business days.
HOW TESTING WORKS
Three checks, before anything ships.
Independent Lab Analysis
Third-party testing confirms purity and identity for every production lot.
Verified Composition
Results are matched against reference standards before a lot is cleared.
Lot-Specific Documentation
Each COA is filed against its exact lot number and published in the COA Library.
What a certificate does and doesn’t say.
A COA is a narrow document. It reports the tests listed on it, by a third-party laboratory, on a sample from the batch named on the certificate.
Only the Lot Tested
Results relate only to the specific sample tested. A COA does not describe other lots, later batches, or material that has been stored, shipped, or repackaged by someone else.
Read It in Full
A single value taken out of context, such as a purity percentage without its method and date, does not represent the full report. Each test answers its own question: purity is not identity, and identity is not quantity.
Not an Approval
A COA is not an approval, certification, accreditation, or endorsement by any laboratory, agency, or Rainier Compounds LLC. It is not a finding that a material is safe, effective, or suitable for any particular use.
All materials sold by Rainier Compounds LLC are intended for laboratory research use only. They are not approved for human or veterinary use, or for therapeutic, diagnostic, or clinical applications. COA results are intended to be reviewed by qualified professionals within the scope of their research. Questions about a specific certificate can be sent to admin@rainiercompounds.com with the product name and lot number.
