How we evaluated it

How it scores Our rating, metric by metric Good, 3.5 of 5

Leaves & farming 25% of the rating 4 of 5

USDA lists Matchaful as an organic handler with Kiwami Super Ceremonial Matcha. The page names the farm (Hattori, Shizuoka) and cultivar (Okumidori), says it is stone-milled to order and prints a Best By date. No harvest year is given.
Independent testing 30% of the rating 4 of 5

Two sets of numbers that agree: Matchaful’s 2026 report (lead 68.8 ppb, fluoride 130 mg/kg, no pesticides detected) and an independent 2025 SGS test of an earlier batch (lead 73 ppb). Lead and fluoride are present, and the maker’s lab name is blacked out.
What touches the tea 15% of the rating 4 of 5

A powder in a 30 g tin, or in a 100 g or 1 kg bag. No tea bag is involved. The pages do not say what the bags are made of.
Trust 10% of the rating 3 of 5

No Prop 65 notices or recalls found, and it publishes lab reports. But it blacks out the lab’s name, calls its metals extremely low when its lead sits mid-range among tested matchas, and sells with health wording.
Value 20% of the rating 2 of 5

$49 for 30 g is about $1.63 a gram, the highest of the matchas here ($0.98 a gram in the 100 g bag).

Where to buy Stores and the prices we saw 1 store

Amazon (opens in a new tab) approx. $56 for the 30 g tin. Sold by Matchaful Inc. and shipped by Amazon, $7 more than the maker’s own site. The title says “Organic ... Super Ceremonial Matcha” and the page carries Amazon’s USDA Organic badge. Whole Foods lists it too, but its page showed no price.

Who paid, and why it matters

Independent The tester took no money from the maker for it: a consumer group, a journalist, a university or a regulator.
Paid certification An outside lab or certifier tested or listed it, and the maker paid for that.
Maker’s own test A lab report or certificate of analysis the maker commissioned and published.

A certification is a floor, not a verdict: it checks what its program checks and nothing else. We weigh tests by someone with no stake in the result most.

What people ask Worries raised online and elsewhere, and what we found 5 questions

Is there lead in it?: Yes, in every report. 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 level 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 for women of childbearing age, and FDA (opens in a new tab) says no safe level has been identified. See our lead guide.
Whose lab is it, and who paid?: Matchaful paid for its 2026 reports and blacked out the lab’s name, so we treat them as the maker’s own. Its lab results post (opens in a new tab) calls them independent and accredited. The 2025 SGS test was independent, funded by Lead Safe Mama’s community. The two agree within 5 ppb on lead, though they cover different batches.
Are its metals really “extremely low”?: Matchaful says so. Lead Safe Mama’s 2025 tests (opens in a new tab) of nine matchas found lead from 23 to 153 ppb; Kiwami’s 73 ppb is in the middle, and Lead Safe Mama says it has not found an uncontaminated matcha. Lower than some, not low.
Is the product USDA lists the one you buy?: USDA’s listing says “Kiwami Super Ceremonial Matcha” and the shop sells “Organic Kiwami Single Cultivar Matcha”, which the page says is now USDA Certified Organic. Lead Safe Mama’s 2025 sample description for this matcha uses both names (“Super Ceremonial ... Single Cultivar”), and Amazon’s title for the 30 g tin joins “Organic” and “Super Ceremonial”, so it looks like one product under a new name, but we could not confirm it.
What about fluoride?: Matcha is the whole leaf, and fluoride goes with it. Matchaful’s own 2026 report gives 0.013 % for Kiwami, which is 130 mg/kg: about 0.26 mg in a 2 g bowl and 0.52 mg in a 4 g latte. A 2022 study found 118 to 122 mg/kg in matcha powder and 3.4 to 4.0 mg/L in the brewed infusion (study (opens in a new tab)), so this sits a little above that, and a 2021 test of US teas found matcha had the most (study (opens in a new tab)). See our fluoride guide.

Why we chose it What put it on our list 4 points

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, fluoride 130 mg/kg, and 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. The only ingredient is matcha.

Trade-offs What to weigh before you buy 5 points

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.
It also contains fluoride: 130 mg/kg in Matchaful’s report, a little above the 118 to 122 mg/kg a 2022 study found in matcha powder. Only lead was checked by the outside lab.
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, fluoride 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. At 73 ppb, the outside result sits in the middle of the nine matchas Lead Safe Mama has tested (23 to 153 ppb).

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.

Alternatives Other options to compare 2 options

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, at a 5 ppb limit.
