Teething toys/teethers: HMTc Standard

Standard

The Heavy Metal Tested & Certified standard for teething toys/teethers. A contact-product standard: limits are heavy-metal MIGRATION and total-content limits from toy-safety, childcare-article, and food-contact-material law: not dietary maximum levels. Each limit is the strictest credible government value in the correct basis, by lookup; basis is never conflated.

How every number on this page is set

What this standard coversCovers teethers and teething toys a child mouths. General children’s toys without a mouthing-specific role are certified under Category 21 (Children’s Toys).

Teething toys/teethers is a contact product, not a food. Its heavy-metal limits are element migration limits from the material a child mouths (EU Toy Safety Directive 2009/48/EC Category III scraped-off; ASTM F963; the EN 71-3 test standard): not dietary maximum levels. The standard for each analyte is the strictest limit set by any credible government regulator for this product in its own basis: a lookup of sovereign law, with the measured quantity stated on every row. Where no instrument directly governs the exact product form, a pacifier is excluded from the Toy Safety Directive, a disposable diaper from the REACH textile restriction, the limit is read across from the nearest applicable sovereign limit and labelled as a read-across, never asserted as direct governance. Migration limits (what leaves the article into saliva or food) and total-content limits (how much metal the article contains) are different quantities measured by different methods; they are published as separate ceilings and never combined into one number. A certified product meets every applicable limit at once, each on a like-for-like basis.

Inorganic arsenic and methylmercury are not published for this category: they are ingestion-and-bioaccumulation speciation forms with no migration counterpart in a contact article, and the total-element ceilings (total arsenic, total mercury) bound them. Where a cell is marked not material, no regulator sets a limit and no exposure pathway exists; the determination is recorded, not left blank.

Master Limit Table

Limits in mg/kg, in the basis named on each row. “ND” means not detectable at the regulation’s stated detection limit: the strictest possible ceiling. Sub-rows (↳) are companion ceilings in a different basis that also apply. Every claim analyte is equal at the gate. A product is certified only when every analyte is at or below 100% of its published government floor or disclosed read-across; above the limit, on any metal, it is not certified and carries no mark. Antimony is regulated in the toy-migration instruments and screened, but is not one of the ten HMTc certification analytes.

Screened, not limited

All ten HMTc certification analytes are accounted for. The analytes below carry no published ceiling for this product because no exposure pathway and no government limit exist; each determination is recorded here rather than left as a silent gap. They are screened during certification, not certified against a number.

AnalyteWhy it carries no ceiling for this product
Inorganic arsenic (iAs)Contact-product arsenic limits regulate total arsenic; no toy-safety instrument sets an inorganic-arsenic limit. Bounded by the tAs migration ceiling.
Methylmercury (MeHg)Methylmercury has no formation or migration pathway in a teether. Bounded by the tHg migration ceiling.

Derivation: every government value, side by side

Each row lists every government limit weighed for this analyte in the governing basis, converted to mg/kg; the HMTc limit is the strictest of them. Companion total-content ceilings appear in the Master Limit Table above, not here, because they are a different measured quantity.
