How to get Manufacturing license for Special Mixtures of Fertilizers, Bio-Fertilizers & Organic Fertilizers in India

Introduction

• The manufacture of customized fertilizer blends plays a critical role in modern agricultural management, where nutrient requirements vary significantly across agro-climatic zones, cropping systems, and soil health conditions. To ensure that these specialized formulations are produced in a controlled, consistent, and scientifically validated manner, the Government of India, through the Ministry of Agriculture and Farmers Welfare, mandates a dedicated registration mechanism under the Fertilizer (Control) Order, 1985 (FCO, 1985).
• This regulatory framework establishes uniform standards for manufacturing special mixtures, bio-fertilizers, and organic fertilizers, while ensuring that only competent and compliant entities are authorized to produce them. The registration system not only safeguards farmers against substandard or unapproved products but also promotes responsible nutrient management, quality assurance, and sustainable agricultural practices nationwide.

What Constitutes a Mixture of Fertilizers? 

Under the Fertilizer (Control) Order, 1985 (FCO), a mixture of fertilizers is defined as any product obtained by combining two or more straight, complex, or specialty fertilizers in predetermined proportions. These mixtures formulated with or without the addition of permitted inert carriers and can be produced in physical, powder, crystalline, or granular form, depending on the nutrient requirements and intended method of application.
A fertilizer mixture is not merely a random blend. It represents a scientifically balanced formulation designed to deliver essential primary, secondary, or micronutrients in a harmonized manner. Such mixtures are typically developed based on soil-test values, crop nutrient demand, regional deficiency patterns, and agronomic recommendations.
The definition under the FCO includes, but is not limited to:

• NPK (Nitrogen–Phosphorus–Potassium) mixtures:
• Customized nutrient combinations tailored to match crop growth stages and yield targets.
• Micronutrient blends:
• Formulations that provide trace elements such as zinc, boron, copper, iron, and manganese to correct specific soil deficiencies.
• Integrated NPK + Micronutrient mixtures:

Advanced blends that combine both macro- and micronutrients in a single product to enhance nutrient synergy, reduce application frequency, and improve nutrient-use efficiency.
These mixtures serve a vital role in modern nutrient management by:

• Ensuring balanced and site-specific nutrition,
• Improving soil fertility and crop performance,
• Reducing nutrient wastage and application costs, and
• Enhancing overall productivity through precise and need-based nutrient delivery.

Eligibility Criteria — Who Can Apply?

Registration for manufacturing special mixtures of fertilizers, bio-fertilizers, and organic fertilizers is open to a broad range of entities engaged in agricultural input production. Applicants must have adequate technical capability, blending infrastructure, and compliance systems to meet FCO standards. Importantly, the proposed special mixture must not already be covered under their existing Certificate of Manufacture issued under Clause 36 of the FCO.

Eligible Categories of Applicants

The following entities are eligible to apply for this registration:

• Individual entrepreneurs engaged in fertilizer blending or agricultural input production.
• Partnership firms involved in manufacturing or supplying fertilizer products.
• Private limited companies or registered corporate entities in the agro-input sector.
• Co-operative societies operating fertilizer production or distribution units.
• Agro-input manufacturers seeking to expand into customized or special mixtures.
• Fertilizer blending units producing multi-nutrient or customized formulations.
• Bio-fertilizer and organic fertilizer producers requiring authorization for new or specialized products.

Documents required for Application  

To secure registration for manufacturing special mixtures of fertilizers, bio-fertilizers, or organic fertilizers under the FCO, 1985, applicants must submit the following key documents demonstrating regulatory compliance and technical capability:

a. Purchaser Requisition 

A formal request from the buyer clearly specifying the required special mixture. Since such mixtures are produced only against confirmed demand and not for general sale, this requisition forms the primary basis for approval.

b. Application in Form E

The prescribed Form E, submitted in duplicate, providing essential details about the applicant, proposed mixture composition, production capacity, and blending facilities. Accurate disclosure is crucial for regulatory assessment.

c. Prescribed Fee (Clause 36)

Payment of the mandated government processing fee under Clause 36 of the FCO. Proof of fee submission must accompany the application.

d. Certificate of Source

A declaration identifying the authorized suppliers of raw materials and confirming that all inputs comply with FCO standards. This ensures the use of legally approved fertilizer components in the mixture.

e. Compliance with Sections 12, 13 & 14 of FCO, 1985

Applicants must demonstrate adherence to the technical and operational requirements specified in these sections, including:

• Adequate plant and machinery for blending
• In-house laboratory and quality control systems
• Proper storage, handling, and safety infrastructure
• Qualified technical personnel for supervision
• Compliance with statutory labeling and record-keeping

This ensures the applicant’s capability to manufacture safe, consistent, and high-quality fertilizer mixtures.

Applicability – When Is This Approval Required? 

This approval is required whenever a manufacturer intends to produce any fertilizer mixture that goes beyond the formulations already covered under their existing Certificate of Manufacture. It applies specifically to cases where the production is demand-driven, customized, or formulated for a particular client or purpose. Manufacturers must obtain this authorization when:

• Producing special mixtures tailored for an individual purchaser, institutional buyer, or government agency.
• Preparing customized NPK or micronutrient blends designed to meet crop-specific, soil-specific, or region-specific nutrient requirements.
• Manufacturing bio-fertilizer or organic fertilizer mixtures based on the specific needs outlined by the purchaser.
• Participating in government or private tenders that require unique or non-standard fertilizer compositions.
• Developing or supplying any formulation not listed in their existing FCO manufacturing registration.

Conclusion

The registration for manufacturing special mixtures of fertilizers, bio-fertilizers, and organic fertilizers serves as a critical regulatory mechanism to ensure that customized nutrient formulations are produced responsibly, safely, and in alignment with national standards. By mandating a formal approval process under the Fertilizer (Control) Order, 1985, the Government of India safeguards farmers from substandard products, promotes scientific accuracy in nutrient management, and supports manufacturers in adopting structured, compliant, and quality-driven production practices.
This framework not only enables the creation of precise, crop-specific, and soil-specific fertilizer blends but also strengthens operational credibility, enhances transparency, and contributes to broader goals of sustainable agriculture. Manufacturers who adhere to this process are better positioned to meet market demands, participate in institutional procurement, and deliver high-quality customized solutions that support long-term agricultural productivity and soil health.
