Last year, Asia Palm Oil magazine asked me to discuss U.S. Borax and how we help the palm oil industry with our boron fertilizer products. Here is the Q&A:

As a leading supplier of borates, briefly share how U.S. Borax is advancing the oil palm industry.

U.S. Borax traces its roots to California’s Death Valley, where borate deposits were discovered in 1872. The first 20 mule team hauled borax 165 miles through Death Valley in 1883. Fully loaded with two ore wagons and a 1,200-gallon water wagon, the rig weighed 36.5 tons. Though the expansion of railways led to the 20 mule team’s retirement, the team has lived on for more than a century as a trademark for U.S. Borax.

Since 1924, we have shipped products from our facility in the Port of Los Angeles. The refinery and shipping operation produces and ships more than 36,000 tons of packaged goods and more than 300,000 tons of bulk material to customers in Europe, Malaysia, and China.

Today, U.S. Borax is acknowledged as the world leader in borate technology, research, and development.

How did U.S. Borax grow to a massive 1,700 locations globally? What is the current demand for the refined borates industry?

U.S. Borax supplies about one-third of the world’s need for refined borates. We have grown our business through our high standard for quality and purity, ensuring the best performance for growers and fertilizer manufacturers. Our technical, scientific, and agriculture experts are dedicated to continuous research and product improvement as well as a high level of personalized, customer service. The bottom line is that we care about our customers’ crops. That’s why U.S. Borax mines and refines only top-quality boron, free of unwanted contaminants.

Borates are used in fertilizers as a mineral essential to plant growth. What are the advantages of boron fertilizer for oil palm?

As a micronutrient, boron is essential to plant growth. Adequate boron is necessary for proper absorption of macronutrients and for maintaining the integrity of plant cell walls.

Adequate boron is a crucial factor in high crop yields and quality. Existing research indicates that boron plays a significant role in:

  • The strength of plant cell walls
  • Membrane function and cell division
  • Stimulation/inhibition of metabolic pathways
  • Development of flowers and fruit
  • Both new and reproductive growth

The function of boron in oil palm is essential and helps:

  • Prevent “fishbone leaf ” (the development of extremely small, thin pinnae)
  • Prevent “hooked leaf ” (a single or double hook on the pinnae near the tip)
  • Eliminate of white stripe occurrence in leaves
  • Prevent seedless fruitlet (parthenocarpy)
  • Form adequate fresh fruit bunches
  • Enhance root growth

What boron fertilizer products does U.S. Borax manufacture for the oil palm industry?

Fertibor® is our primary product sold in SEA for palm oil, but we also offer Solubor® and Granubor®. Fertibor (15% B) is a fine crystalline borate ideal for NPK compound fertilizers and suspensions. Manufactured as free-flowing granules, Fertibor is easily handled and offers superior flow and consistency.

U.S. Borax’s parent company launched its first integrated sustainability strategy in 2018. Why was the Roundtable on Sustainable Palm Oil (RSPO) platform chosen? How important is sustainability to U.S. Borax?

We’ve been an affiliate member of the RSPO since 2008. The RSPO has developed a set of environmental and social criteria which companies must comply with in order to produce Certified Sustainable Palm Oil (CSPO). When they are properly applied, these criteria can help to minimize the negative impact of palm oil cultivation on the environment and communities in palm oil-producing regions.

The RSPO has more than 4,000 members worldwide who represent all links along the palm oil supply chain. They have committed to produce, source, and/or use sustainable palm oil certified by the RSPO. Not only RSPO, we also encourage plantation and small holder to adopt MSPO/ISPO for sustainability of oil palm business.

U.S. Borax is committed to adopting high standards, often going beyond legal requirements, on the sustainability issues that are material to our business, our employees, the communities that host us, and the customers that buy and use our products.

Our world’s population is growing rapidly—yet the amount of arable land is not. A changing climate. Soil contamination and depletion. Crop demands. All threaten our ability to maintain a sufficient global food supply.

U.S. Borax wants to help farmers meet society’s needs today without hindering future generations’ ability to feed themselves. Through our sustainable agriculture policies, we promote farming practices and methods that are environmentally conscience, good for local communities, and profitable for growers.

Has the pandemic dampened the growth of U.S. Borax’s business in the oil palm industry and how has it affected expansion plans (if any)?

We saw some challenges and new rules and regulations on the way we operate in the value chain at the start of pandemic. But, once we understood the “new normal” and adapted, we were back on the right track as in our plans. Our business continues to grow and develop in the palm oil industry. The majority of plantation users are aware of the significance of borates in fruit formation. They are using our product to increase the quantity and quality of FFB in order to capitalize on the current market’s high CPO prices.



U.S. Borax, part of Rio Tinto, is a global leader in the supply and science of borates—naturally-occurring minerals containing boron and other elements. We are 1,000 people serving 650 customers with more than 1,800 delivery locations globally. We supply around 30% of the world’s need for refined borates from our world-class mine in Boron, California, about 100 miles northeast of Los Angeles. Learn more about Rio Tinto.
