Each row is one of the twelve flags on the COA flags sheet, in the flag’s own words, under the part of the paperwork it is read against; a flag that recurs prints its line once. The sheet sets no limit and no specification: those are the buyer’s regulator’s to set, and the site holds none. Tick a row once the paperwork has been read against its flag and the flag does not apply.
Identity and purity
The certificate’s identification block and the assay block.
A certificate needs an independent lab with an address you can reach. The brand testing itself is a claim, not a result. Open flag 1 on the COA flags sheet
A COA is a statement about one batch. Without the number it describes nothing you can hold. Open flag 2 on the COA flags sheet
Extract tested, tincture sold. The numbers describe a drum, not a bottle. Open flag 3 on the COA flags sheet
A ratio of chromatogram peaks is not a mass. Ask for the assay against a reference standard, by weight. Open flag 9 on the COA flags sheet
Pass has to say pass against what, and someone has to put their name to it. An unsigned PDF is a PDF. Open flag 12 on the COA flags sheet
Residual solvents
The solvents panel, read against the process the supplier states.
Solvents the supplier never used, all clean; the one they did use, absent. Ask which solvents the process ran on. Open flag 11 on the COA flags sheet
Not detected against an unstated limit says very little. The LOQ column is the substance of every ND. Open flag 6 on the COA flags sheet
Heavy metals
The metals panel, every line with its limit of quantitation.
Microbial
The microbial panel, every line with its limit of quantitation.
Pesticides
The pesticides panel, every line with its limit of quantitation.
Potency reconciliation
The cannabinoid panel, read against the label and the units it uses.
mg/g on a liquid with no density, or a label in mg/mL against a certificate in mg/g. Ask for the density or a matching unit. Open flag 5 on the COA flags sheet
Total CBG that adds CBGA without saying so. Ask which figure the label counts. Open flag 7 on the COA flags sheet
Stability time points
The test date on this certificate, and the dates on the ones before it.
Acids convert and neutrals oxidise, so a panel drifts. Ask for a date you would accept as recent, per batch. Open flag 4 on the COA flags sheet
Reading this sheet
Informational only, not medical or legal advice; regulations and limits vary by jurisdiction, and the site holds none.
