Why is moisture measurement critical in food manufacturing?
India’s Legal Metrology framework is updating. The recent update focuses on measuring moisture in cereal grains and oilseeds. On 6th August 2025, the Ministry of Consumer Affairs, Food and Public Distribution notified the Legal Metrology (General) Fourth Amendment Rules, 2025. This regulation adds the Seventh Schedule. It sets uniform standards for moisture meters across India.. These changes will come into force starting 1st January 2026
This amendment is crucial for the food manufacturing industry and post-harvest stakeholders. Moisture measurement is important for determining grain quality, market value, storability, and processing viability. Different testing equipment gives different results. This creates problems everywhere grain procurement. Government buyers argue with suppliers over moisture levels. Farmers face disputes at local markets.
The government embeds standardisation in Legal Metrology India’s compliance framework. This builds accountability and accuracy across the supply chain. It covers everyone from farmers to food manufacturers
What does the Seventh Schedule mandate?
Under the new rules, the Seventh Schedule has been officially added to the Legal Metrology (General) Rules, 2011. This schedule outlines precise technical specifications and testing procedures for moisture meters. The aim is to eliminate discrepancies caused by non-standardized or outdated equipment.
From January 1, 2026, all moisture meters must follow the Seventh Schedule. This applies to meters used for cereal grains and oilseeds. It covers procurement, warehousing, food processing units, and mandis.
Key provisions include:
- Performance calibration and equipment verification
- Mandatory certification for all new devices under the Legal Metrology Act, 2009
- Compliance enforcement through Weights and Measures Departments
This ensures consistent calibration standards and promotes legal accountability in trade practices.
How should manufacturers and food businesses prepare?
The Legal Metrology Amendment gives stakeholders a transition period before enforcement begins. This offers food importers, food manufacturers, and testing labs time to align their practices and equipment. Proactive action is advised to avoid operational disruption post-deadline.
For equipment manufacturers and importers:
- Devices must conform to the prescribed specifications.
- Certification through NABL labs and official verification is mandatory.
For food manufacturing units and traders:
- Only certified moisture meters are ideal for grain quality assessment.
- Businesses should audit current calibration procedures to ensure compliance.
- Legal metrology rules will now apply more strictly in quality-related transactions.
These changes will influence contract negotiations. Grain value often depends on moisture percentage.
Strengthening Legal Metrology India’s Role in Fair Trade
The Legal Metrology (General) Fourth Amendment Rules, 2025 improve transparency and regulatory standards in India’s food trade. They add a specific schedule for moisture meters. This move helps ensure fair and tamper-proof transactions in agriculture and food production. Stakeholders should start planning for compliance now. The deadline is 1st January 2026, with no expected extensions.
