How limits are set
The standard for each analyte is the strictest maximum level set by any credible government regulator — among them the European Union, Codex Alimentarius, the US FDA, Australia/New Zealand, the Gulf states (GSO), and the national authorities of every jurisdiction that regulates the product — converted into Hot sauce and chili sauces’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. 5 of 11 analytes carry a firm ceiling; the remaining 6 are governed by mandatory control or the total-metal screen with no standalone number, itemised in the derivation below. A brand meeting every firm value on a like-for-like basis, and passing every control, qualifies for the mark.
| Analyte | HMTc limit | Binding basis |
|---|---|---|
| Lead (Pb) | 1000 | strictest government ML (China) |
| Cadmium (Cd) | 1000 | strictest government ML (Vietnam) |
| Total arsenic (tAs) | 1000 | strictest government ML (Singapore) |
| Inorganic arsenic (iAs) | 100 | strictest government ML (China) |
| Mercury, total (tHg) | 50 | strictest government ML (Vietnam) |
| Methylmercury (MeHg) | n/m | not material — controlled analyte (see note) |
| Nickel (Ni) | control | mandatory control — no government ML; screened every lot (see note) |
| Tin (Sn) | n/m | not material — controlled analyte (see note) |
| Aluminium (Al) | control | mandatory control — no government ML; screened every lot (see note) |
| Total chromium (Cr) | control | mandatory control — no government ML; screened every lot (see note) |
| Hexavalent chromium (Cr-VI) | control | mandatory control — no government ML; screened every lot (see note) |
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.
Derivation
For Hot sauce and chili sauces, each HMTc limit is the strictest maximum level any credible government sets for the product, named in the Binding column with the count of jurisdictions that concur at that value. Where no government regulates the analyte, the cell is a mandatory control or a not-material determination, never an invented number.
| Analyte | HMTc | Binding | Basis |
|---|---|---|---|
| Lead (Pb) | 1000 | China · +2 concurring | direct sovereign ML |
| Cadmium (Cd) | 1000 | Vietnam | direct sovereign ML |
| Total arsenic (tAs) | 1000 | Singapore · +1 concurring | direct sovereign ML |
| Inorganic arsenic (iAs) | 100 | China | direct sovereign ML |
| Mercury, total (tHg) | 50 | Vietnam | direct sovereign ML |
| Methylmercury (MeHg) | n/m | ≤ tHg | not material in this matrix |
| Nickel (Ni) | control | screened every lot | mandatory control — no government ML |
| Tin (Sn) | n/m | controlled | not material in this matrix |
| Aluminium (Al) | control | screened every lot | mandatory control — no government ML |
| Total chromium (Cr) | control | screened every lot | mandatory control — no government ML |
| Hexavalent chromium (Cr-VI) | control | screened every lot | mandatory control — no government ML |
Risk Flag
On the published occurrence literature to date, Hot sauce and chili sauces 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.
