Scope
NC 877:2012 applies to wheat flour for human consumption, including prepackaged wheat flour ready for sale to consumers and wheat flour intended for use in other food products. It excludes durum-wheat products, wholemeal flour or semolina, wheat flour for brewing adjunct use, starch or gluten manufacture, and non-food industrial uses.
HMI records only the section 6.1 heavy-metal values that NC 877:2012 quotes from NC 493:2008 for processed cereals. This PDF does not contain the full NC 493:2008 contaminant table.
Exact limit and units
Section 6.1 states that wheat flour must comply with NC 493, where the maximum contents of metallic contaminants in processed cereals are 0.1 mg/kg lead and 0.1 mg/kg cadmium. The structured evidence register converts those values to ug/kg by multiplying by 1000.
| Species | Matrix | Limit | Unit | Structured value |
|---|---|---|---|---|
| Pb | Processed cereals, including wheat flour under NC 877:2012 | 0.1 | mg/kg | 100 ug/kg |
| Cd | Processed cereals, including wheat flour under NC 877:2012 | 0.1 | mg/kg | 100 ug/kg |
How tested
NC 877:2012 lists analytical methods for wheat-flour quality parameters such as moisture, ash, protein, gluten, granulation, acidity, falling number, and microbiology. The source does not name a metal-specific analytical method for lead or cadmium; it requires compliance with NC 493 for the quoted metal limits.
Enforcement posture
NC 877:2012 is a Cuban national standard issued by the Oficina Nacional de Normalizacion. The source frames the heavy-metal requirement as a food-safety condition for wheat flour: wheat flour must not contain heavy metals in quantities that could represent a danger to human health and must comply with NC 493. The PDF excerpt does not provide a separate enforcement procedure for the metal rows.
History of changes
The source is the first edition of NC 877:2012, dated May 2012. It states that the standard is a national adoption of the Codex Standard for Wheat Flour, STAN 152-1985, revised in 1995, and it references NC 493:2008 for metallic contaminants in foods. The source does not provide amendment history for NC 493:2008.
How it compares
The recorded values are processed-cereal limits as quoted in a wheat-flour standard. They are comparable to lead and cadmium limits for cereal, grain, and flour products in other national contaminant standards, but should not be treated as the full Cuban NC 493 contaminant schedule.
Because this source quotes NC 493 rather than reproducing the full NC 493 table, any comparison outside processed cereals or wheat flour needs the primary NC 493:2008 standard.
