The below insights provide detailed information about the composition, handling, and safety standards of our matcha - ensuring full compliance with international quality and safety regulations. Each batch is meticulously tested and traceable, upholding the integrity and trust that define the Kamashh name.

What is a Certificate of Analysis (COA) in Matcha?

A Certificate of Analysis (COA) is a laboratory report that verifies the safety and composition of a product.

For matcha, this includes testing for:

  • Heavy metals such as lead, arsenic, cadmium, and mercury
  • Microbial safety
  • Purity and composition

Because matcha is made by consuming the entire leaf, purity is not optional—it is essential.

Why Heavy Metal Testing Matters in Matcha

Matcha is grown in soil, shade, and time.

Like all agricultural products, tea plants can absorb elements from the environment.
Without testing, these remain unknown.

When you drink matcha, you are not infusing leaves - you are consuming them entirely.

Which is why testing matters more in matcha than in regular tea.

Our MSDS isn’t just a formality - it’s an assurance of authenticity, responsibility, and uncompromising quality in every product we offer to our consumers.

The Standard

Understanding Quality & Purity

What does a Certificate of Analysis include?

A Certificate of Analysis reflects the integrity of what you are consuming.
For matcha, it includes verified testing for purity, safety, and consistency - covering parameters such as heavy metals, microbial levels, and overall composition.

At Kamashh, this is not a formality, but a standard that ensures every batch meets a considered level of quality.

Is Kamashh matcha tested for heavy metals?

Yes. Each batch is evaluated to ensure it meets defined safety benchmarks, including testing for heavy metals and other contaminants.

This level of scrutiny allows Kamashh matcha to be enjoyed with confidence - whether occasionally or as part of a daily ritual.

How can I verify matcha authenticity?

Authenticity is rarely a single marker. It is reflected through origin, cultivation, processing, and verification.

Matcha of genuine quality is typically sourced from Japan, stone-ground from first harvest leaves, and supported by documentation such as a Certificate of Analysis. Kamashh follows this philosophy closely - prioritising provenance and process over volume.

Is it safe to consume matcha daily?

When matcha is properly sourced and tested, it can be a considered part of a daily routine.

Kamashh matcha is selected and evaluated to support consistent, everyday consumption - offering a balanced, refined experience without unnecessary compromise.

Why is testing important for matcha?

Matcha is consumed in its entirety, which makes purity essential.

Testing ensures that what appears vibrant and refined is also clean and safe beneath the surface. For Kamashh, this step reinforces a simple principle - quality should be evident not only in taste, but in trust.
