Certificates
Certification & Laboratory Testing
Our philosophy is simple: safety and transparency. Every batch of matcha undergoes independent tests (pesticides, heavy metals, microbiology incl. E. coli, yeasts and moulds, and PAHs). For key product lines, the National Institute of Public Health (NIPH / SZÚ) issues a Health Safety Certificate.
Why we test
Matcha is consumed whole (not just an infusion), hence rigorous control is essential. We keep batch protocols for fast retrieval and audit readiness, monitor EU compliance, and ensure quality consistency via sensory checks (colour, aroma, taste, texture).
Our control process
- Sampling & sealing — directly in Japan, full traceability.
- Independent testing — accredited labs (multiresidue pesticides, heavy metals, microbiology, PAHs).
- Internal verification — comparison with limits + sensory evaluation.
- Batch release — approval for sale and protocol archiving.
What exactly we test
- Pesticides — multiresidue screening (wide spectrum, LOQ per method).
- Heavy metals — Pb, Cd, Hg, As (ICP‑MS).
- Microbiology — E. coli, yeasts & moulds, total plate count (accredited methods).
- PAHs — targeted determination of polycyclic aromatic hydrocarbons.

Frequently asked questions
How fast can you provide a batch report?
We archive reports per batch for immediate retrieval. On request we send both a summary and the full PDFs.
Which laboratories do you use?
Primarily accredited laboratories, e.g., ALS. The scope/LOQ follows the methodologies of the given lab.
Do you run cross‑region comparisons?
Yes, we conduct long‑term comparative testing across regions. We prefer Japanese origin for stability and safety.
