The instrument
This page records the heavy-metal maximum levels set by Cuba NC 877:2012 - wheat flour metal contaminants, the instrument of Oficina Nacional de Normalizacion, 2012. Every value below is transcribed into the Heavy Metal Index register from the primary text and is the value an HMTc standard cites when this jurisdiction binds a certification limit. It is a record of law, not an HMTc threshold.
Maximum levels
All values µg/kg (ppb), in the basis the instrument states. 2 maximum levels across 2 analytes and 1 product category, grouped by analyte and ordered by limit.
| Limit µg/kg | Basis | Product scope | Provision |
|---|---|---|---|
| Lead (Pb)1 limit | |||
| 100 | product as placed on market | processed cereals; wheat flour under NC 877:2012 | NC 877:2012 section 6.1 quotes NC 493:2008 for processed cereals |
| Cadmium (Cd)1 limit | |||
| 100 | product as placed on market | processed cereals; wheat flour under NC 877:2012 | NC 877:2012 section 6.1 quotes NC 493:2008 for processed cereals |
Where HMTc cites it
Cells where this instrument holds the strictest government value in force among credible regulators, and therefore binds a published HMTc limit.
A limit recorded above binds nothing today only because another government holds a stricter value for every published cell. It may still bind later, as other jurisdictions relax or as a new subcategory is published.
How this interacts with HMTc
HMTc certification standards adopt the strictest existing maximum level set by any credible government, applied cell-by-cell. Where this instrument holds the strictest value for a (product, analyte) cell, it binds the HMTc limit and the standard cites this page. This page does not set or justify any HMTc threshold; it records the sovereign requirement the program measures against.
A reference page is a record of law, not an HMTc threshold. It states what a government requires; the standard page states what the program requires, and names which instrument binds each cell.
