Published Certificates

Batch Certificate Index

Certificates are added as stock arrives and stay published after a batch sells out — a unit bought six months ago should still be checkable.

What Gets Tested

Five screens, on every batch.

Potency. The full cannabinoid profile, including THCa, delta-9 THC and total THC. Cali Clear liquid diamonds test at 90–95% THC.

Pesticides. More than 60 individual compounds, each measured against the state action limit. This is the screen that answers the question people actually mean when they ask whether Cali Clear has pesticides — the results are on every certificate below.

Heavy metals. Lead, arsenic, cadmium and mercury. These matter for vape hardware specifically, because metals can leach from a poorly made coil into the oil over time — which is one reason hardware quality and oil safety are not separate questions.

Residual solvents. Traces left behind by the extraction process — butane, propane, ethanol and others. A clean extraction leaves almost nothing; the certificate shows how much.

Microbials. Yeast, mould, E. coli, salmonella and Aspergillus species.

How to Read a Cali Clear COA

Most people have never read a certificate of analysis and there is no reason they should have. Here is what the sections mean, so the document is useful rather than decorative.

The cannabinoid profile

You will usually see three numbers that look like they should match and don’t: THCa, delta-9 THC, and Total THC.

Raw cannabis contains THCa, which is not psychoactive. Heat converts it to delta-9 THC. Because THCa is a heavier molecule, the conversion is not one-to-one — labs calculate total THC as:

Total THC = (THCa × 0.877) + delta-9 THC

That 0.877 factor is why a certificate can show a low delta-9 figure alongside a high total, and it is the number that matters for what you actually experience.

Pass, fail and “ND”

Pesticide, metal, solvent and microbial screens report against a limit rather than as a raw score.

• ND — not detected. The compound was below the instrument’s detection threshold.
• < LOQ — present but below the limit of quantitation. Detectable, not measurable, and well under any action limit.
• PASS — detected and quantified, but under the regulatory limit.
• FAIL — over the limit. A batch that fails does not ship.

A certificate showing a small quantified figure with PASS is not a worse result than ND. It means the instrument was sensitive enough to see something and the amount was legally and practically irrelevant.

Test date and batch match

Two things to check that people skip:

1. The batch number on the certificate matches the box in your hand. A certificate for a different batch proves nothing about your unit.
2. The product on the certificate matches your product. Same flavor, same format. A 2g certificate does not cover a 1g.

What ISO/IEC 17025 Accreditation Actually Means

This is the difference between “lab tested” as a marketing phrase and lab tested as a fact.

ISO/IEC 17025 is the international standard for testing and calibration laboratories. A lab holding it has been audited by an external accreditation body on its methods, its equipment calibration, its staff competence and its quality management — and is re-audited to keep it.

Any laboratory can run a test and print a result. An accredited laboratory has had a third party verify it is capable of running that test correctly. When a seller says “lab tested” without naming the lab or publishing the certificate, there is no way to know which of those two you are getting.

Every certificate on this page names the laboratory that produced it.

If Your Batch Isn’t Listed

A batch number that returns nothing here means one of three things, in rough order of likelihood.

It came through a different retailer. We publish certificates for stock we hold. An authentic unit bought elsewhere will have its own batch record — ask that seller for it.

The number was mistyped. Batch codes mix letters and digits, and 0/O and 1/I are easy to confuse. Check it once more.

The unit is not authentic. If the batch does not exist anywhere and the QR code on the box does not resolve, that is the answer. Our verification guide sets out the full check and what to do next.

If you bought from us and your batch is not here, contact us and we will publish it or replace the unit.

Frequently Asked Questions

Is Cali Clear lab tested? Yes. Every batch is tested by an ISO/IEC 17025 accredited laboratory for potency, more than 60 pesticide compounds, heavy metals, residual solvents and microbial contaminants. The certificates are published on this page.

Does Cali Clear have pesticides? Every batch is screened for more than 60 pesticide compounds against state action limits, and a batch that fails does not ship. The results for any batch we stock are in the certificate index above — you can read the actual figures rather than take a claim on trust.

Where do I find my Cali Clear batch number? The batch number is printed on the bottom sticker of the retail box, right next to the QR code. It appears as an alphanumeric code (e.g., “CC-240915-V6-TUSI”). See the photograph above for the exact location.

What is a COA? A certificate of analysis is the laboratory’s formal report on a specific batch, listing what was tested, the method used, the measured results and whether each result passes the applicable limit.

Is Cali Clear third party tested? Yes. Testing is carried out by an independent accredited laboratory, not in-house. The laboratory is named on every certificate.

How current are these reports? Certificates are published as stock arrives and remain available after a batch sells out, so a unit bought months ago can still be checked.
