How every number on this page is set
What this standard coversCovers soothers/pacifiers and sucking/teething aids (the nipple, shield, ring, and any clip in the mouthing zone). Teething toys with play value are certified under Teething toys/teethers; pacifier metal safety is governed via the EN 1400 soother standard.
Pacifiers and sucking/teething aids is a contact product, not a food. Its heavy-metal limits are the element-migration limits required by the EN 1400 soother standard, which applies the EN 71-3 / Toy Safety Directive Category III limits. Pacifiers are excluded from the Toy Safety Directive itself (Annex I item 16), so these migration limits are read across from the toy-migration regime via the EN 1400 route; the limit values are identical — 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. Tier 1 (Pb, Cd, iAs, Hg) are zero-tolerance toxics; Tier 2 (tAs, Ni, Al, Cr-VI, Sn) carry a transitional allowance under the program’s Status A–E framework. Antimony is regulated in the toy-migration instruments and screened, but is not one of the ten HMTc certification analytes.
| Analyte | Tier | HMTc limit | Basis | Strictest government | Rationale |

| Lead (Pb) | Tier 1 | 23 | element migration from scraped-off toy material (Category III); source unit mg/kg | European Union (read-across) | regulatory-alignment |

| Arsenic, total (tAs) | Tier 2 | 47 | element migration from scraped-off toy material (Category III); source unit mg/kg | European Union (read-across) | regulatory-alignment |
| Cadmium (Cd) | Tier 1 | 17 | element migration from scraped-off toy material (Category III); source unit mg/kg | European Union (read-across) | regulatory-alignment |

| Tin (Sn) | Tier 2 | 180000 | element migration from scraped-off toy material (Category III); source unit mg/kg | European Union (read-across) | regulatory-alignment |
Screened, not limited
All ten HMTc certification analytes, plus a total-chromium screen, 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.
| Analyte | Why it carries no ceiling for this product |
|---|---|
| Inorganic arsenic (iAs) | Contact-product arsenic limits regulate the total arsenic element; no toy-safety or soother instrument sets an inorganic-arsenic limit. Inorganic arsenic is a dietary speciation with no migration counterpart. The tAs migration ceiling bounds the inorganic fraction. |
| Methylmercury (MeHg) | Methylmercury is a marine-bioaccumulation speciation with no formation or migration pathway in a pacifier or teether. Every contact-product mercury limit is on total mercury. The tHg migration ceiling bounds any organomercury fraction. |
| Chromium, total (Cr) | The governing soother/toy-migration instrument (EN 71-3 / Directive 2009/48/EC Annex II Part III Category III, applied via the EN 1400 soother standard) regulates hexavalent chromium specifically (Cr-VI, 0.053 mg/kg migration), not total chromium. The only sovereign total-chromium toy limits (ASTM F963, Mexico NOM-252, China GB 21027 soluble total-Cr, all ~60 mg/kg) are far more permissive than the Cr-VI migration ceiling and would understate control if published as the total-Cr standard. Total chromium is therefore screened, not assigned a published limit; any detectable total chromium reflexes to Cr-VI speciation, which binds at the Category III migration limit. |
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.
