Reader ratings
Organic single-cultivar matcha from one named Shizuoka farm. Matchaful’s lab report shows lead at 68.8 ppb, about 0.14 µg per 2 g serving; an outside lab found 73 ppb in an earlier batch. Every tested matcha we found had lead.
Best for Matcha drinkers who want a named farm, an organic listing and lab numbers they can read.

How we evaluated it
Why we chose it What put it on our list
- Matchaful posts three 2026 lab reports. The Kiwami report (reported 4 Feb 2026) shows lead 68.8 ppb, cadmium 15.6, arsenic 17.4 and mercury below 5, with no pesticides detected in two screening panels.
- An outside test of an earlier batch is close. Lead Safe Mama, an advocacy group, sent a January 2025 batch to SGS North America and got lead 73 ppb, cadmium 16 and arsenic 16.
- The USDA Organic Integrity Database lists Matchaful (certifier CCOF, status effective 6 Nov 2024) with Kiwami among its certified products.
- It names the farm and the cultivar, says it is stone-milled to order, and prints a Best By date on the package.
Trade-offs What to weigh before you buy
- It still contains lead. At 68.8 ppb (68.8 µg per kg), a 2 g serving carries about 0.14 µg and a 4 g latte serving, the size Matchaful suggests, about 0.28 µg. California’s Prop 65 safe-harbor level for lead is 0.5 µg a day, so two such lattes would exceed it. FDA’s interim reference levels for lead from all food are 2.2 µg a day for children and 8.8 µg a day for women of childbearing age, and FDA says no safe level has been identified.
- The lab’s name is blacked out in Matchaful’s PDFs, so those reports are the maker’s own. The outside check is a single 2025 batch.
- The USDA database lists “Kiwami Super Ceremonial Matcha”, while the shop sells “Organic Kiwami Single Cultivar Matcha”. We could not confirm they are the same product under a new name.
- $49 for 30 g is about $1.63 a gram ($0.98 a gram in the 100 g bag). Matchaful says to use an opened container within a month, so a bigger bag only pays off if you drink it daily.
What to know Details worth knowing first
Matcha is the one tea where you drink the whole leaf, so whatever the leaf carries ends up in the cup. Our matcha guide says to buy from producers that test. Every matcha we found with an outside lab result had lead in it, so the question is how much, and whether you can see the numbers.
Kiwami is listed because Matchaful shows its numbers and an outside lab’s result for an earlier batch is close to its own. The reports cover heavy metals, pesticide residues and radioactive cesium and iodine. The lab’s name is blacked out in the PDFs, so we treat them as the maker’s own. The USDA database confirms the organic listing.
What the lead figure means: at 68.8 ppb, a 2 g bowl carries about 0.14 µg of lead and a 4 g latte about 0.28 µg. California’s Prop 65 safe-harbor level for lead is 0.5 µg a day, and FDA’s interim reference levels for all dietary lead are 2.2 µg a day for children and 8.8 µg a day for women of childbearing age. One serving is under the Prop 65 level and well under FDA’s, and FDA’s figures cover all the lead in a day’s food. It is not zero, and our lead guide notes that no blood level is known to be safe. If you drink matcha every day, weigh that against steeped tea, where you do not drink the leaf.
Quality & testing How it measures up against our checklist
- Third-party tested
- Yes
- Tested by
- SGS North America (outside test of a 2025 batch for Lead Safe Mama); the lab is not named in Matchaful’s own reports
- Certificate of analysis
- Yes
| What we checked | What we found |
|---|---|
| Tested for lead and pesticides Verified | Matchaful’s 2026 report: lead 68.8 ppb, cadmium 15.6, arsenic 17.4, mercury below 5; two pesticide panels not detected at the limit of quantitation; radioactive cesium below 1 Bq/kg. An outside lab’s report on a 2025 batch gave lead 73, cadmium 16, arsenic 16 and mercury not detected. The outside test covered metals only; the pesticide results are in Matchaful’s own report. |
| Organic Verified | Matchaful, Inc dba Matchaful is certified by CCOF (NOP ID 5561004703) under the USDA National Organic Program (status effective 6 Nov 2024). The listing names Kiwami Super Ceremonial Matcha. |
| Named origin Maker’s claim | Hattori Tea Farm, Shizuoka, Japan; single cultivar Okumidori. This comes from Matchaful’s page. |
| Loose leaf or plastic-free bags Maker’s claim | A powder, not a tea bag, sold in a 30 g tin or in 100 g and 1 kg bags. The pages do not say what the bags are made of. |
| Freshness Maker’s claim | Matchaful says it is stone-milled to order, prints a Best By date on the package and advises using an opened container within a month. No harvest year is stated. |
| Notices and recalls Verified | We found no California Prop 65 notices and no FDA recalls naming Matchaful when we searched on 22 Oct 2026. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.

Alternatives Other options to compare
- Matchaful Hikari Single Origin Matcha From the same farm and cheaper ($42 for 30 g, $79 for 100 g), but the USDA database does not list it as organic.
- Matchaful Houjicha Roasted green tea powder from the same seller, with less lead in Matchaful’s report (about 45 to 50 ppb) and a lower price ($30 for 30 g). It is not matcha.
- A steeped loose-leaf tea You drink the infusion rather than the whole leaf, and it costs far less per cup. An outside lab found no lead in a strong brew of this one.
