Lab Results And Testing Transparency
Scientific Transparency & Lab Verified Purity
"I built Kyoto Botanicals after I accidentally got high in the lab."
As a former biologist, I respect data above all else. Early in our formulation days, I realized that "0.3% THC" isn't just a legal limit, it’s a variable that can add up quickly. After feeling the effects of legal full-spectrum extract myself, I realized the industry had a transparency crisis. I founded Kyoto Botanicals to fix that. We don't just test our products; we audit them with a Zero-Tolerance Protocol for THC and contaminants. This rigid standard is a core part of our process, ensuring that every formulation remains consistent from the raw hemp extract to the final bottle on your shelf.
The Kyoto Botanicals Standard:
Every batch listed below is verified 0.0% THC (Non-Detect) and meets the federal 0.4mg THC-per-container limit. As a founder-operated brand, I personally review every COA before a single bottle ships. If it doesn't meet my standards, it never enters your home.

Why Third-Party Testing is Non-Negotiable
Hemp is a powerful bio-accumulator. It is often used in bioremediation to clean soil because it naturally sucks up everything, including heavy metals, pesticides, and toxins. Without rigorous screening, your CBD wellness products can easily become delivery systems for environmental pollutants.
Consumer Safety
Screens for pesticides, heavy metals, residual solvents, and pathogens like E. coli and Salmonella to ensure biological safety.
Label Accuracy
Confirms that the mg of CBD on the label is actually the mg in the bottle. We prioritize this data to eliminate the common industry issue of CBD lab results vs label claims, ensuring you get exactly what you pay for. Consistency is key for effective routines.
2026 Federal THC Compliance
Verifies compliance with the 2026 federal 0.4mg THC-per-container limit for hemp-derived CBD products.
The Reality of the Audit: Why We Reject Batches
"Transparency is more than just a PDF link: it’s about the logic of the supply chain. I recently rejected a batch because the dates didn't add up. The testing date for the raw hemp extract was listed after the bottling date and the best buy date did not align with the bottling date. In science and chain of custody, the timeline must be linear. If the temporal data is inconsistent, the batch can't be trusted. We don't just collect COAs; we audit them for truth."

The Full-Panel Safety Screen
We work with ISO/IEC 17025 labs (SC Labs & ACS) to perform standardized analysis on every batch. We match the right instrument to the right safety question.
Potency & Cannabinoids (HPLC)
We use High-Performance Liquid Chromatography (HPLC-DAD) to quantify CBD, CBG, CBN, and THC without using heat that could alter the delicate plant compounds.
Pesticide Screen
Using Liquid & Gas Chromatography-Mass Spectrometry (HPLC-MS/GC-MS), we screen for over 50 compounds to guarantee purity and safety.
Residual Solvents
We verify the total removal of extraction solvents (like CO2 or Ethanol) through GC-MS so there are zero chemical leftovers in your CBD oil.
Heavy Metals (ICP-MS)
The gold standard for detecting trace levels of Lead, Mercury, Arsenic, and Cadmium that may have been absorbed from the soil.
Mycotoxins (HPLC-MS)
Confirming every batch is free from the metabolic toxins, high-performance liquid chromatography-mass spectrometry is used to detect these resilient molds.
Microbiology
polymerase chain reaction (PCR) and fluorescence detection of microbiological contaminants like E. coli and Salmonella.
How Kyoto Botanicals Compares to Industry Norms
| Testing Category | Typical CBD Brand | Kyoto Botanicals |
|---|---|---|
| Batch Frequency | 1–2x per year (Random) | Every Single Batch |
| Pesticide Screen | 20–40 compounds | 50+ compounds |
| Heavy Metal Screen | Often skipped to save cost | Every product batch |
| THC Guarantee | "Under 0.3%" | Verified 0.0% (Non-Detect) |

Our Independent Laboratory Partners
We exclusively partner with ISO-accredited facilities that lead the industry in hemp-derived cannabinoid research and compliance.
The Science Inside the Lab
Accuracy isn't about a single machine; it's about matching the right method to the right question. Our partner labs use gold-standard instrumentation:
- HPLC (High-Performance Liquid Chromatography): Used to quantify CBD and minor cannabinoids without heat, ensuring the profile is 100% accurate.
- ICP-MS (Inductively Coupled Plasma-Mass Spectrometry): The gold standard for detecting trace levels of lead, arsenic, and mercury.
- HPLC-MS/GC-MS: Highly sensitive tandem chromatography used to screen for pesticides and mycotoxins.
Common Questions About Lab Testing
How do I read the THC levels?
Look for Δ9-THC. In a Kyoto Botanicals report, you are looking for "ND" (Non-Detect). This means the THC level is so low the equipment cannot find it. For a deeper technical guide, see our manual on How to Read a COA.
What is an ISO/IEC 17025 accreditation?
It’s the global gold standard for laboratory competence. It means the lab’s people, methods, and equipment are audited for accuracy and reproducibility. We only work with ISO-accredited partners like SC Labs and ACS Laboratory.
Is your CBD tested for pesticides?
Yes. While federal law only requires a handful of screens, we run an advanced pesticide screen to ensure our organic CBD remains pure from farm to bottle.
Why does Kyoto test for heavy metals in every batch?
Because hemp is a bio-accumulator, it can absorb toxins from soil or water. Many brands skip this to save costs, but we screen every batch for Lead, Mercury, Arsenic, and Cadmium to ensure your products stay clean.
Are lab results the same as FDA approval?
No. The FDA does not "approve" or "certify" CBD products. In this unregulated landscape, a third-party COA is the only report card available. It is the brand’s responsibility to provide this transparency, and our responsibility as a founder-operated brand to audit those results before a single bottle is shipped.
Is Kyoto Botanicals compliant with the 2026 0.4mg THC rule?
Yes. While many Full Spectrum products now exceed federal limits per container, our Broad-Spectrum process ensures every bottle and gummy pack stays well below the 0.4mg limit while keeping the beneficial terpenes intact.
