How limits are set
The standard for each analyte is the strictest maximum level set by any credible government regulator — the European Union, the United Kingdom, Codex Alimentarius, Health Canada, China, India, Brazil, the Gulf states (GSO), Australia/New Zealand, and the US FDA — converted into Fruit purées’s own as-consumed basis. It is a lookup of sovereign law, carrying at most one disclosed basis conversion where the law is written in another basis, and an explicit read-across where no government regulates the exact product. A certified product sits at or below every applicable sovereign limit at once.
Where no government regulates the exact product for an analyte, the standard does not go blank or invent a number: the limit is read across from the nearest government value for an analogous product, so a certified product still sits at or below a real sovereign limit. The ratchet tightens these after publication as surveillance warrants.
Master Limit Table
All values in ppb (µg/kg), as-consumed basis. Every analyte carries a firm ceiling. A brand meeting every value on a like-for-like basis qualifies for the mark.
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. Arsenic is limited in both forms: total arsenic (tAs) and inorganic arsenic (iAs) are separate ceilings that must both be met, and the species result never replaces the parent total. Total chromium is limited as shown; hexavalent chromium is controlled through it — mandatory Cr-VI speciation on any total-chromium result above 100 ppb, and any quantifiable Cr-VI fails.
Derivation
The full derivation for Fruit purées. Each row lists every government maximum level in force worldwide, converted to the as-consumed basis; the HMTc limit is the strictest of them, and the last column names which sovereign law binds. A blank cell means that government sets no limit for this analyte in this product.

|---|---|---|---|---|---|---|---|---|
| Lead (Pb) | — | 50¹ | — | 100¹ | 20¹ | 100¹ | 10 | PA |
| Inorganic arsenic (iAs) | 20¹ | — | 200¹ | — | 150¹ | — | 20 | EU |
| Total arsenic (tAs) | — | — | — | — | — | — | 50² | read-across |
| Mercury (tHg) | — | — | — | — | — | — | 8² | read-across |
| Cadmium (Cd) | 40¹ | 40¹ | 60¹ | — | 100¹ | 40¹ | 40 | EU |

| Tin (Sn) | — | — | — | — | — | — | 5000² | read-across |

All values µg/kg (ppb), as-consumed basis. ¹ basis-converted at the 8:1 powder-to-liquid ratio — the only such ratio a government legislates (China GB 2762 footnote c). ² read-across: no government sets this analyte for this exact product; the value is read across from the nearest government value for an analogous product. ³ not material in this matrix: measured but with no standalone number, controlled by the total-metal screen, not an invented value.
Occurrence and derivation rationale
For each analyte on the panel: what the peer-reviewed and survey literature measured in this category, cited one way to the Heavy Metal Index, and the Method v2.0 reasoning behind the certification limit — including, where no government sets a number, why the program sets one anyway. Occurrence figures are literature findings; the derivation is the certifier's.
No citable primary occurrence measurement is routed to this cell in the corpus.
HMTc sets 10 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. Why lead is limited →
No citable primary occurrence measurement is routed to this cell in the corpus.
HMTc sets 20 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. Why inorganic arsenic is limited →
No citable primary occurrence measurement is routed to this cell in the corpus.
HMTc sets 8 ppb by read-across: government read-across — Israel FCS-2016 porridges & other foods for infants and toddlers, total-Hg 8 (the strictest applicable baby-food mercury ML; supersedes the looser China canned-complementary 20). Why total mercury is limited →

HMTc sets 40 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. Why cadmium is limited →

HMTc sets 500 ppb (regulatory-alignment): the strictest applicable government maximum level for this product form, adopted under Method v2.0 as the default certification standard. Why nickel is limited →

HMTc sets 5 mg/kg by read-across: government read-across (India FSSAI "Infant Milk substitute and Infant foods" Sn 5000, the only non-canned tin ML in the register) applied at face value. Why tin is limited →
No citable primary occurrence measurement is routed to this cell in the corpus.
HMTc sets 500 ppb by read-across: government read-across (AU-NZ Schedule 19 infant-formula Al 500, the only government aluminium ML in any jurisdiction) applied at face value; the 8:1 reconstitution factor is formula-specific and is not applied to a non-formula product. Why aluminium is limited →
Risk Flag
On the published occurrence literature to date, Fruit purées shows no systematic gap between typical market levels and the limit — the limit being the strictest government maximum for the product (Method v2.0). Certification is decided on a product’s own tested result, not on a distribution; an individual lot or supplier can still exceed a limit.
