Overview
ISO 19942:2018/Amd 1:2020 is an international standard amendment that specifies requirements for maize (Zea mays L.), with a focus on feed maize intended for animal nutrition. This amendment builds upon the original ISO 19942:2018 standard by defining minimum quality specifications applicable to maize used in animal feed within international trade contexts.
The standard is developed and maintained by ISO Technical Committee ISO/TC 34, Subcommittee SC 10, which focuses on animal feeding stuffs. It ensures quality, safety, and uniformity in feed maize through clear limits on moisture content, impurity levels, and grading classifications.
Key Topics
Moisture Content Limits
- Human consumption maize: Maximum moisture content of 14.5% (mass fraction) according to ISO 6540.
- Feed maize: Maximum moisture content set at 14.0% (mass fraction) to maintain feed quality and prevent spoilage.
Impurities Specifications
- Defined maximum permissible impurity levels vary between maize for human consumption and feed maize.
- For feed maize, the maximum impurity levels include:
- Broken grains: up to 10%
- Damaged grains: up to 10%
- Miscellaneous impurities: up to 2%
- Total impurities: maximum 15%
Grading System for Feed Maize
- Feed maize is classified into three grades based on broken grain content:
- Grade 1: Max 6% broken grains
- Grade 2: Max 8% broken grains
- Grade 3: Max 10% broken grains
- Grading assists in assessing feed quality and plays a fundamental role in pricing and trade negotiations.
Applications
ISO 19942:2018/Amd 1:2020 is essential for stakeholders involved in the production, trade, and quality control of feed maize, including:
- Animal feed manufacturers who require consistent raw material quality for optimal nutrition.
- Agricultural producers and exporters to ensure maize meets international trade requirements.
- Regulatory bodies and quality assurance teams tasked with compliance verification and safety standards.
- Commodity traders and pricing analysts using grading to set transparent market values.
By adhering to these specifications, businesses can minimize risks associated with poor-quality maize, such as spoilage due to moisture or contaminants from impurities, thereby enhancing the safety and efficiency of animal feeding operations globally.
Related Standards
- ISO 6540 – Determination of moisture content in cereals, which is used to assess maize moisture.
- ISO/IEC Directives – Guidelines followed for drafting and maintaining ISO standards, ensuring harmonized quality and clarity across all ISO documents.
- Standards from ISO/TC 34 on other food products and animal feed materials, providing complementary frameworks for feed safety and quality.
By implementing the requirements set forth in ISO 19942:2018/Amd 1:2020, organizations contribute to improving the international trade standards of animal feed maize, safeguarding both animal health and market reliability. This amendment enhances clarity and uniformity, supporting global agricultural and feed industries in maintaining high-quality production processes.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
