Stainless steel water bottles, rated on what they’re made of

• The plastics are stated to be “free from phthalates (BPA, BPS, BPF) including DEHP, lead and cadmium” and “independent lab tested”. The lab is not named and no report is published, which is why the backing points are partial rather than full. [1]
• The interior is electropolished bare steel with no lining — stated, which is the question most insulated bottles dodge. [1]
• The vacuum seal solder is not addressed. The lead claim covers the plastics only. [1]
• Manufacturing spans “Australia, United Kingdom, China” and is not resolved per part. An Australian brand, but not an Australian-made product as such. [1]

• The testing claim is the broadest in this category and the least specific: “All our products are tested by a global independent testing body to international standards. Test reports confirm that are no traces of BPA, Phthalates, PVC, lead or heavy metals detected”. No body is named, no standard is named, no reports are published. [1]
• “No traces… detected” is meaningless without a detection limit, and none is given. Compare YETI, which publishes 0.002 mg/kg. [1]
• The internal valve material is not published. Silicone cure type not stated. [1]
• Country of manufacture not published. Top-rack dishwasher only. [1]

• The powder-coated exterior’s composition is not published. That is true of every coated bottle we checked, without exception. [1]
• Lead in the vacuum seal is not addressed. No brand in this category publishes a detection limit or a numeric result. [1]
• Silicone cure type not stated and no standard body cited. [1]
• Country of manufacture and warranty not published. Hand wash. [1]

• The claim string contains “PBS-free”, which is not a substance — almost certainly a typo for BPS. Sloppy enough to undermine confidence in the rest of it. [1]
• Oasis has no functioning brand site we could reach. Every material claim above comes from retailers, not the maker. [1]
• Exterior coating composition not published. Lead in the vacuum seal not addressed. [1]
• Hand wash recommended. No warranty published. [1]

• CamelBak gives you the families and does not map them to parts. You cannot tell from the page which component is the PP copolymer and which is the silicone. [1]
• Powder coat composition not published. [1]
• Lead in the vacuum seal is not addressed. The page does carry a California Proposition 65 notice stating the stainless steel “may contain Nickel, Chromium, Manganese, and Iron”. [1]
• Country of manufacture not published. “The whole thing is dishwasher safe.” [1]

• That claim has no test data, no detection limit and no lab behind it. It matters here more than usual, because Stanley’s own support article shows the vacuum seal is exactly where lead sits in insulated bottles — and MontiiCo asserts the opposite without evidence. [1] [2]
• Straw and gasket materials are not published. Exterior coating not published. [1]
• Six-month warranty, the shortest in this category by a distance. [1]
• Country of manufacture not published. MontiiCo has absorbed both Little Lunch Box Co and The Lunch Punch — both domains now redirect here. [1]

• That admission is honest and it is buried. The Australian product page says only “BPA-free” and is completely silent on lead. A shopper reading the listing would never learn it. [1] [2]
• Also stated: “no lead is present on the surface of any Stanley product that comes into contact with the consumer nor the contents of the product”. No detection limit and no numeric test result are published. [2]
• “Stanley tests for and validates compliance on all products through FDA-accredited 3rd party labs” — labs not named, reports not published. [2]
• The FlowState lid and the reusable straw are the mouth-contact parts and neither polymer is named. Nor is the gasket, nor the powder coat. [1]
• Country of manufacture not published. Lifetime warranty, dishwasher safe. [1]

• Their origin statement is “All Cheeki products are ethically made in China. The facilities we use meet strict international standards for fair and safe labour and working conditions.” That is a labour claim, and no standard, auditor or certifying body is named. It says nothing about product testing, despite sounding like it might. [1]
• No third-party testing or laboratory named for the steel or the bamboo lid. [1]
• The gasket material is not specified. [1]
• No warranty found. [1]
• On the lead question generally, see the sealing dot explained — single-wall bottles like this one sidestep it entirely.

• The cap body polymer and the gasket are not named, and “Klean Coat” is a trade name with no published composition. [1]
• “BPA Free and Lead Free” is asserted with no test result and no detection limit. [1]
• Country of manufacture not published. [1]
• “Strong as Steel Lifetime Limited Warranty”; caps dishwasher safe. [1]

• The four lid materials are listed together without saying which part is which. The drinking spout is lid-side and therefore food-contact, and its specific material is not identified. [1]
• The steel grade is not published. No 304, no 18/8, no 316, and no statement about whether the interior is lined or coated. [1]
• This is the only product in the Anko range that names ABS — and the only plastic-containing Anko product with no BPA claim at all. Kmart puts “BPA free” on $2 polypropylene containers and omits it on a bottle whose lid is explicitly ABS. [1] [2]
• Not suitable for microwave, dishwasher or freezer. The near-identical 530ml version of the same bottle carries no such restriction and is simply silent — same declared materials, different care rules. [3]

• It ships with a handle lid, a twist-spout lid, a flip-straw lid and two reusable straws. Three lids and two straws are direct mouth-contact items and not one has a stated material. [1]
• The exterior is black, implying a powder coat or paint, and the exterior finish is not disclosed either. [1]
• No BPA claim on a product with three plastic lids and two plastic straws — a claim that would be trivially cheap to make and is simply absent. [1]
• “304” is asserted, not certified. The page does not say whether the interior is bare 304 or lined, which is the question that matters on cheap insulated bottles. [1]
• No dishwasher guidance at all, which is unusual — nearly every other Ovela product has that field. [1]

• Lead is not addressed on the Australian product page. Press reporting in 2024 noted Hydro Flask marketing itself as not using lead, in contrast with Stanley — we could not find that claim on Hydro Flask’s own Australian site, so treat it as unverified by the maker. [1]
• The Australian page says “Dishwasher safe”. The US page says the bottle is not recommended in a dishwasher because of powder coat heat damage, while lids are. Same product, two regions, opposite advice. [1] [2]
• Country of manufacture not published. [1]
• Lifetime warranty. [1]

• Lead in the vacuum seal is not addressed. [1]
• “Sweat-proof exterior” — finish composition not published. [1]
• The warranty is referred to as “the Thermos® warranty” with no term stated on the page. Top-rack dishwasher only. [1]

• Two bottles in one range, with identical stated composition, where one bans dishwasher use and the other is silent. Only one of those pages can be right. [1] [2]
• “Keeping drinks hot or cold for hours” and “Keeps hot or cool up to 6 hours” appear in the same block — a vague claim and a specific one, side by side. [1]
• Steel grade not published. Lid materials named but not assigned to parts. [1]
• No BPA claim, on a lid that contains ABS. Kmart’s blue variant of this bottle returned a 404 at time of check. [1]

• Steel grade not published. [1]
• Marketed for school — “perfect for days at school” — and the Target listing of the same bottle states it is not dishwasher safe. A kids’ bottle you cannot put in the dishwasher. [2]

• No care instructions, no dishwasher guidance, no warranty, no country of manufacture. [1]
• No BPA or PFAS claim, on a bottle with an undescribed lid. [1]
• Big W’s own-brand bottles are the disclosure floor of this whole audit. Two of them — the Transparent Guzzler 1L and the Single Sipper 750ml — name no material whatsoever, and the Openook Insulated 950ml does not even say whether it is steel or plastic. [2] [3] [4]

• “90% recycled stainless steel” with no grade at all — the weakest steel disclosure of any premium brand here. Recycled content describes provenance, not alloy. [1]
• Lid polymer, gasket and exterior coating: none published. The telescopic straw is stainless. [1]
• Chilly’s materials FAQ is disallowed by robots.txt, so their fullest material statement — if there is one — could not be read. We did not work around the block. [1]
• Hand wash only: “NOT: Dishwasher Safe”. Lead not addressed. Country not published. [1]

• No 18/8, no 304, nothing. For a bottle sold on its steel, the grade is the one number missing. [1]
• “BPA Free: Yes” is a checkbox attached to no named polymer, so it cannot be checked for BPS or BPF substitution. [1]
• Lead in the vacuum seal is not addressed on the maker’s page. [1]
• Country of manufacture not published. Limited lifetime warranty; lid top-rack dishwasher. [1]

• The steel grade is not on the product page. It is in the FAQ — “food grade 304 stainless steel”, and for ceramic items “304 stainless steel coated in food-grade ceramic”. Cite the FAQ, not the listing. [2]
• “BPA-free, lead-free, and non-toxic” with no test data. “Non-toxic” is unqualified and unfalsifiable. [1]
• Origin is stated unusually well: “Designed in Melbourne, Australia, and responsibly assembled in China”. That is the cleanest designed-versus-made split in this whole table and we score it as assembled in China. [1]
• Twelve-month warranty. Lids top rack; bodies hand wash, because “dishwashers can cause patchiness and discolouration on the colour-coated surface”. [1]

• No steel grade. No 18/8, no 304, no food-grade designation — on a $6 double-walled insulated bottle, which is the price point where grade matters most. [1]
• The soft-touch exterior finish is the sort of applied polymer layer that a buyer avoiding coatings would want named. It is not. [1]
• “Hand wash only. Do not microwave.” No warranty, no country of manufacture, no testing. [1]
• No BPA claim, on a bottle with an unnamed plastic lid. [1]

• “Ceramic lined” is a disclosure black hole across this whole category. Both ceramic bottles we scored sell the lining as the feature and publish nothing about it. [1] [2]
• No BPA claim at all on this product — unusual, given a plastic push-button lid. [1]
• A copper lining is mentioned as part of the insulation. Its relationship to the food-contact surface is not explained. [1]
• No country of manufacture, no warranty, no dishwasher guidance. Oasis has no functioning brand site we could reach. [1]

• Tritan is a trade name for a copolyester. It is a named plastic, which is a real answer, but no grade or food-contact standard is cited. [1]
• Lid and gasket materials not published. [1]
• Tritan is marketed on being BPA-free. That excludes BPA and says nothing about the other monomers in a copolyester. [1]
• The pattern generalises: across Big W, Kmart and Target, the branded goods on the shelf disclose more than the house brands beside them, at the same price. [2]

• “FDA & EU approved safe” is doing a lot with four words. The FDA does not approve drink bottles; it regulates food-contact substances. No standard number, approval reference or report is given for either jurisdiction. [1]
• “Nano ceramic lined” is a trade description. What the lining actually is, and how it is applied, is not published. [1]
• “Australia Designed and Owned” appears where a country of manufacture would go. Designed and owned is not made. [1]
