Products and Services

Just as your company plays a crucial part in growing food and raw materials for the world, Seatex serves a vital role helping you expand your reach with our ability to produce your products under your label and get them anywhere around the globe. In this highly regulated industry, it’s imperative to use an EPA-registered manufacturer with strict safety protocols, the know-how to minimize toxicity, and the ability to package with intelligent design. Not only is every one of our facilities registered, we maintain strict segregation between crop production and crop protection products.

Seatex is an ISO 9001:2015 and GMP certified chemical blending company with more than 50 years’ experience. We are a trusted partner of some of the largest agricultural companies in the world, consistently delivering product that keeps the world supplied with necessary essentials. 

Seatex blends millions of pounds a year of fertilizers, micronutrients, specialized nutritionals, and crop protection products. Our dedicated ag production facilities are set up to handle any exothermic, endothermic, or ammoniated products you have. Independent scrubbing systems allow us to manage a variety of raw materials that others struggle with.

We are able to support toll, turn-key, and hybrid models for producing your products. Volume is NOT a problem and we can package in anything from rail car to spray bottles. Let us know what you need and we can do it!

Our experience serving ag producers across the country, including those in major farming areas in Southern U.S., our deep capacity, and our extensive blending certifications make us the perfect match for farming-related companies the world over.


Helping Ag Producers in 3 Market Segments

Plant Nutrition

We take your products and ensure that the blend ratios and manufacturing process ensure plants get the micro- and macro-nutrients they need, from NPK to iron, manganese, copper, zinc, and others. We are equipped to precisely add micronutrients while having the ability to do ammonization to get the right levels of nitrogen. If your products need heating, cooling, scrubbing, or any other special process, let us figure out how to do it.

Crop Protection

Defend crops with our know-how and your products, produced at an EPA-registered blending facility. As a Houston-based company, we have convenient access to the raw materials needed to produce the vast majority of crop protection products. When this advantage is combined with our experienced blenders, our chemists and organization can help you optimize your products for the lowest total cost of ownership.

Soil Health

Soil enhancers represent an important bloc of our customers’ agrochemical needs. These additives help farmers grow their yields and ROIs by improving plant start-up and root health, nutrient intake, stress and drought resistance, and more. Let Seatex produce your products so that we can help contribute to your bottom line health.
