How we evaluated it

How it scores Our rating, metric by metric Fair, 3.4 of 5

Leaves & farming 25% of the rating 4 of 5

A named maker that states the material and the country of each part: glass in Japan, strainer in China.
Independent testing 30% of the rating 2 of 5

We found no lead or cadmium test of this pot, and Hario makes no lead statement. Plain glass and steel carry little risk, so we do not score it a 1, but nothing is checked.
What touches the tea 15% of the rating 4 of 5

Borosilicate glass pot, lid and handle with a stainless steel basket, and no plastic part listed. The details are Hario’s, and we have not handled the pot.
Trust 10% of the rating 4 of 5

No Prop 65 notices or CPSC and FDA recalls found, and no safety wording on its page. It states its use limits plainly: hot water, microwave without the strainer and dishwasher, but no oven, induction hob or open flame.
Value 20% of the rating 4 of 5

$28.50 for 450 mL ($25.50 for 300 mL), about what Rishi charges for its similar 400 mL glass pot ($29). A stainless basket in your own cup costs less.

What it’s made of What touches your food, water, skin or air 3 materials

Strainer basket: stainless steel mesh (made in China)

What people ask Worries raised online and elsewhere, and what we found 4 questions

Is the glass lead-free?: Hario makes no lead statement and we found no lead or cadmium test of this pot. It is plain borosilicate glass, and its page describes no printed or painted decoration, which is where lead has turned up in glass teapots: in 2022 Lead Safe Mama (opens in a new tab) reported that the Tea Bloom brand removed lead-painted logos from its glass pots. We have not handled this one, so look for decoration on the pot you receive. See our lead guide.
Is any part plastic?: None is listed. The product page (opens in a new tab) gives borosilicate glass for the pot and lid and stainless steel for the strainer, and its image description says the lid and handle are glass too. Hario’s ChaCha line has other pots, so check the materials line of the one you buy.
What grade is the stainless steel?: Hario says only stainless steel, and the strainer is made in China. It states no grade (such as 18/8) and we found no test of metal release. A steel basket is the usual plastic-free choice for loose leaf.
Does the company have safety notices?: No. We found no California Prop 65 notice naming Hario and no CPSC or FDA recall for its teapots on 23 October 2026.

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

Hario names the material of every part: heatproof (borosilicate) glass for the pot and lid, and stainless steel for the strainer.
The image description on Hario’s page says the lid and handle are glass as well, with a metal mesh basket. No plastic part is listed.
Hario states the origin by part: glass made in Japan, strainer made in China.
At $28.50 for 450 mL it costs about the same as Rishi’s similar 400 mL glass pot ($29), and Hario’s page carries no Prop 65 warning. We found no Prop 65 notice naming Hario.

Trade-offs What to weigh before you buy 4 points

The materials and origins are Hario’s statements. We found no outside lead or cadmium test of this pot, and the page does not mention any printing or decoration on the glass.
It is for hot water only. Hario says it is safe for the microwave (with the strainer removed) and the dishwasher, and not for ovens, induction hobs or open flame. Borosilicate glass still breaks if dropped.
The strainer is made in China, so it is the one part not covered by the made-in-Japan claim, and its steel grade is not stated.
Hario sells other ChaCha pots too. Check the product name and the materials line before you buy.

What to know Details worth knowing first

Hot water on loose leaf, in a pot with no plastic, is the simplest way to avoid the microplastics that some tea bags shed (see loose leaf vs. tea bags). This Hario pot has a borosilicate glass body, lid and handle and a stainless-steel basket, and its maker lists no plastic part.

We chose it because Hario says where each part is made and nothing about its listing raises a lead flag. That is still the maker’s word, and no lab has tested the pot that we could find. On any glass teapot, look for printed or painted decoration: Lead Safe Mama, an advocacy group, reported in 2022 that a glass teapot brand had removed lead-painted logos after its community raised the issue. Plain glass avoids the question.
