For more than five decades, Bisley International has focused on agricultural chemicals and mineral nutrient raw materials, supporting fertilizer producers and crop nutrition formulators worldwide. From our base in Houston, Texas, we combine reliable global sourcing, technical expertise and long-term partnerships to help growers improve soil health, plant nutrition and sustainable yields.
Founded in 1972, Bisley began as a regional distributor of specialty chemicals. Over time, our strongest growth came from agricultural customers, fertilizer producers and crop nutrition formulators. Building on this experience, Bisley International now focuses exclusively on agricultural chemicals and mineral nutrient raw materials that support modern farming and sustainable food production.
From our base in Houston, Texas, we serve partners across more than 30 countries, supplying calcium, magnesium, phosphate, boron and zinc salts for macro- and micronutrient formulations. Our products are used in straight fertilizers, NPK blends, water-soluble and foliar feeds, as well as soil and seed treatments designed to improve plant vigor, root development and yield stability in a wide range of crops.
Our success is built on three pillars: deep technical understanding of mineral nutrition, reliable global supply chains and a practical appreciation of each customer’s formulation and process requirements. Every batch we ship is sourced from vetted producers, meets strict quality specifications and is backed by responsive commercial and technical support from the Bisley team.
Working closely with fertilizer manufacturers, distributors and crop nutrition brands, we strive to be more than a raw material supplier. We act as a long-term partner, helping our customers secure consistent supply, adapt to changing regulatory frameworks and introduce new nutrient solutions that support efficient, profitable and responsible agriculture.
Bisley International serves fertilizer producers, blenders and crop nutrition brands across multiple continents. From our base in Houston, Texas, we coordinate agricultural chemical and mineral nutrient supply into North America, Latin America, Europe, the Middle East and the Asia-Pacific region, helping customers secure reliable raw materials close to their own manufacturing and distribution hubs.
Our role is to bridge the gap between carefully selected producers of mineral salts and the companies that formulate finished fertilizer and crop nutrition products. We work with customers who produce granular NPK fertilizers, water-soluble and foliar formulations, soil conditioners, seed treatments and specialty nutrient blends designed for high-value crops.
By maintaining a diversified network of production partners and logistics routes, we support our customers in managing seasonality, foreign exchange exposure and regulatory changes. Our team actively monitors global supply and demand dynamics for key nutrients such as calcium, magnesium, phosphate, boron and zinc, and shares these insights to help customers plan their purchasing strategies with confidence.
Whether you operate a single production site or manage multiple plants and distribution centers across several regions, Bisley can help design a supply approach that aligns with your business model, inventory philosophy and crop calendars in the markets you serve.

Wherever your manufacturing or distribution base is located, our goal is to provide stable, traceable and predictable supply of the mineral nutrients that underpin your crop nutrition portfolio.
Bisley was founded in 1972 with a clear ambition: to supply reliable specialty chemicals to local industry. Very early in our history we began working with fertilizer blenders, distributors and agricultural co-operatives, laying the foundations for what would become our long-term focus on crop nutrition and mineral nutrients for farming.
By the mid-1980s Bisley had expanded across five neighboring countries, building distribution networks that increasingly served fertilizer producers and crop nutrition formulators. Regional warehouses, local logistics partners and dedicated agricultural teams allowed us to supply calcium, magnesium and phosphate salts more efficiently to growers and ag retailers.
In 1998 we strengthened our quality systems to align with international standards for the sourcing, handling and distribution of fertilizer-grade mineral salts and agricultural chemicals. Formal quality management, audited production partners and documented specifications became core to how we support customers in developing consistent, safe and compliant nutrient formulations.
By 2010 Bisley was actively serving customers in more than 20 countries across multiple continents. Our agricultural portfolio grew to include calcium formate, calcium gluconate monohydrate, copper sulfate pentahydrate, ferric EDTA, magnesium oxide, magnesium sulfate, monoammonium phosphate, phosphogypsum, ulexite, zinc chloride and zinc sulfate, supporting fertilizer producers and crop nutrition brands worldwide.
Today Bisley International is fully dedicated to agricultural chemicals and mineral nutrient raw materials. We focus our expertise on a carefully curated portfolio that serves fertilizer manufacturers, formulators and distributors, helping them address evolving regulatory requirements, optimize nutrient use efficiency and support productive, sustainable agriculture. Our journey continues as we deepen partnerships and explore new solutions for the next generation of crop nutrition.
Our role goes beyond delivering mineral salts. We work alongside fertilizer manufacturers, blenders and formulators to understand their products, their processes and the markets they serve, and then align our sourcing and logistics to support those goals over the long term.
Each customer has a distinct product portfolio, whether it is focused on bulk granular NPK fertilizers, water-soluble nutrients for fertigation, specialty foliar products, micronutrient blends or seed-applied treatments. We start by understanding these product lines, the role that calcium, magnesium, phosphate, boron and zinc salts play in them, and the performance expectations in the field.
From there, we discuss grades, particle size requirements, solubility targets, impurity limits and regulatory considerations relevant to the markets in which our customers operate. This allows us to match the right raw materials and production partners to each customer’s needs and ensure that those choices remain robust as volumes grow and regulations evolve.
Throughout the relationship, we maintain regular communication on demand planning, shipping schedules and any changes in market conditions that could affect availability or pricing of key nutrients. The objective is to provide our customers with transparency and options so they can manage their own commitments to distributors, retailers and growers.
Our team is available to discuss both technical and commercial questions, from suitability of a specific grade for a new formulation to broader conversations about diversifying supply or introducing new nutrient concepts into a given market.
We review your fertilizer and crop nutrition portfolio, target crops, application methods and geographic markets to identify where mineral nutrients are most critical to performance.
Together we define specifications for calcium, magnesium, phosphate, boron and zinc salts that fit your formulations, processes, storage conditions and regulatory environment.
We develop sourcing and logistics plans that reflect your production cycles, seasonal peaks and inventory strategy, aiming to deliver consistent availability and predictable lead times.
As your portfolio, volumes or regulatory context change, we reassess options and adjust sourcing strategies so that your crop nutrition business can continue to grow on a stable foundation of raw material supply.
Whether you are developing a new fertilizer concept or scaling an established brand, Bisley aims to be a stable, knowledgeable and responsive partner in the background of your crop nutrition operations.
Agricultural inputs are increasingly regulated and scrutinized. Bisley International works with established producers and focuses on clear specifications, traceability and documentation so that our customers can meet their own quality, safety and regulatory obligations with confidence.
We collaborate with producers that operate formal quality systems and have the capability to meet agreed specifications batch after batch. For our agricultural chemicals and mineral nutrients, we pay close attention to nutrient content, impurity levels, particle size distribution, moisture and other properties that can affect performance in fertilizer and crop nutrition formulations.
Our internal procedures ensure that product information is captured, reviewed and made available to customers in a consistent way, supporting their own quality assurance frameworks and helping avoid surprises in production or in the field.
Fertilizer and crop nutrition products must increasingly comply with region-specific regulations and labelling requirements. We pay attention to regulatory frameworks in the markets where our customers operate, including limits on certain impurities, classification rules and documentation needs, and we take these factors into account when sourcing and recommending products.
While compliance responsibility ultimately sits with the finished product manufacturer, our goal is to provide transparent, reliable information about the agricultural raw materials we supply so that customers can complete their own evaluations more efficiently.
For the mineral nutrients and agricultural chemicals in our portfolio, we provide the technical documentation that fertilizer producers and crop nutrition formulators expect, including technical data sheets, safety data sheets and, where applicable, detailed product specifications and typical analysis information.
This documentation supports internal quality checks, formulation work, registration activities and conversations with distributors and growers. Our team can also help clarify how a given agricultural raw material is typically used in fertilizer or crop nutrition applications, providing context to the data on paper.
We pay attention to traceability from producer to customer, including batch identification and shipment details, so that our customers can integrate this information into their own quality and recall procedures. In agriculture, where multiple seasons and crops may depend on a single formulation, having access to this level of detail helps maintain confidence throughout the supply chain.
Over time, this focus on consistency and traceability helps reduce variability in finished products and supports more stable performance in the field.
Questions about a new market, a change in regulation or the suitability of a particular mineral nutrient grade are a normal part of growing an agricultural business. Our team is available to discuss such topics, share perspective from other markets where appropriate and help identify practical options for our customers.
The aim is not to replace customers’ own regulatory or technical teams, but to complement them with targeted information about the agricultural raw materials we supply.
Quality, compliance and documentation are not static requirements; they evolve with science, regulation and customer expectations. Bisley takes a long-term view of these topics, building relationships with producers that are prepared to adapt and investing time in understanding how our customers’ needs are changing.
This long-term perspective underpins our commitment to being a stable partner in the agricultural sector, supporting fertilizer and crop nutrition businesses as they navigate a changing landscape.
Every agricultural chemical and mineral nutrient we supply is sourced from vetted producers and measured against strict specifications for purity, nutrient content and consistency. Our internal QA processes and partner audits help ensure that fertilizer manufacturers and crop nutrition brands receive materials that perform predictably in their formulations and application systems.
We continuously refine our portfolio of mineral nutrients and agricultural chemicals to support new fertilizer concepts, from high-analysis NPK blends to specialty foliar feeds and water-soluble formulations. By working closely with formulators, we help introduce grades and raw materials that improve solubility, compatibility and nutrient use efficiency in the field.
Agriculture depends on timing, and so does our supply chain. We focus on dependable logistics, clear communication and forward planning so that our customers can secure the right mineral salts ahead of critical production and planting windows. Consistent quality and on-time delivery help fertilizer producers and distributors keep their own commitments to growers.
We support nutrient solutions that contribute to healthier soils, efficient fertilizer use and responsible food production. By focusing on high-quality mineral nutrients and transparent specifications, we help our partners design products that support crop performance while taking into account environmental regulations, runoff concerns and long-term agricultural sustainability.
Our team understands how calcium, magnesium, phosphate, boron and zinc salts behave in different fertilizer systems and application methods. We work with customers to select appropriate grades, consider solubility and compatibility, and translate mineral specifications into practical crop nutrition solutions that perform reliably in the field.
We see ourselves as a long-term partner to fertilizer producers, crop nutrition brands and distributors, rather than a transactional supplier. Transparent communication, shared planning and a clear understanding of each customer’s markets allow us to build resilient supply strategies and support mutual growth across the agricultural value chain.
Let's discuss how Bisley's agricultural chemicals and mineral nutrient raw materials can support your fertilizer or crop nutrition business.
Answers to common questions about Bisley International as a supplier of agricultural chemicals and mineral nutrients.
Bisley International supplies agricultural chemicals and mineral nutrient raw materials that are used by fertilizer manufacturers, blenders, distributors and other professional buyers. Our products become components of finished fertilizers, foliar sprays, soil conditioners, seed treatments and other crop nutrition solutions. We focus on quality, consistency and documentation rather than operating as a retail outlet or advisory service to individual growers.
Our customers are primarily businesses involved in fertilizer and feed production, blending, distribution and formulation. This includes manufacturers of bulk and specialty fertilizers, micronutrient blends, foliar products, seed treatments and feed premixes, as well as traders and distributors who supply these materials to their own clients. We do not position ourselves as a direct input supplier to small-scale farmers or home gardeners.
Bisley focuses on agricultural markets in Australia, New Zealand, Asia, the Middle East and North America. Within these regions we supply to ports and logistics hubs that connect into local fertilizer, feed and distribution networks. Availability of specific products can vary by country due to regulations, product registrations and logistics considerations, so we review each enquiry individually.
No. Bisley supplies raw materials and intermediate products to professional customers such as fertilizer manufacturers, blenders and distributors. These businesses formulate and package finished fertilizers and crop nutrition solutions that are then sold to growers through their own channels. We do not operate as a retail store or online shop for finished fertilizers or farm inputs.
We can explain the typical uses and characteristics of our products, but we do not provide field-level agronomic advice, application rates or cropping recommendations. Those decisions must be made by qualified agronomists, advisors and end users who understand local soils, crops, regulations and product labels. Information on our site and in our literature is intended for general background only.
We work with established producers and manufacturing partners, and we operate within formal quality management frameworks such as ISO 9001:2015. Typical supply arrangements include agreed specifications, regular quality checks and traceable documentation. Certificates of analysis, technical data sheets and safety data sheets can be provided so that customers can perform their own assessments and quality controls.
For most products we can provide technical data sheets, typical specifications, safety data sheets and, where applicable, certificates of analysis relating to specific batches. Additional documentation may include origin statements or regulatory information, depending on the product and destination market. The exact package of documents is agreed as part of the commercial discussion for each supply arrangement.
In many cases we can support customers who are developing custom formulations by supplying specific combinations of raw materials or by coordinating with manufacturing partners. Whether a particular blend or formulation is feasible depends on product compatibility, regulatory conditions, minimum order quantities and technical constraints. These projects are always handled in close cooperation with the customer’s technical and commercial teams.
Packaging options vary by product and region, but can include bulk shipments, big bags, standard bags and selected liquid packaging options. The most suitable format depends on handling equipment, storage conditions and downstream use. We discuss packaging during the enquiry process to align with customer requirements and local logistics practicalities.
For some products it is possible to supply smaller quantities for laboratory work, product development or limited field trials. The feasibility of trial quantities depends on product type, manufacturing constraints and logistics. Customers who are interested in trials should share their requirements so that options can be assessed on a case-by-case basis.
Logistics and delivery are tailored to the product, quantity and destination. We usually work with established shipping lines, freight forwarders and local logistics partners to deliver to agreed ports or hubs. Incoterms, lead times and any special handling requirements are defined in the commercial agreement so that customers can plan inbound supply with confidence.
We can provide product-related information and documentation that may support our customers’ regulatory and compliance processes, for example technical data and safety data sheets. However, responsibility for obtaining registrations, approvals and ensuring compliance with local regulations always remains with the customer and the final product owner. We do not act as a regulatory authority or legal advisor.
Storage and handling requirements depend on the specific product. General principles include keeping materials dry, protected from contamination and within the temperature ranges stated on the product documentation. Safety data sheets and product labels should always be read and followed. Customers are responsible for implementing suitable storage, handling and safety procedures at their own facilities.
