About Our Company

Chewa (ชีวา) in Thai means ‘life’. Incorporated in 2012, Chewachem was named for the important role of chemical fertilizers in sustaining life through agriculture.

We are an integrated solutions provider that imports, trades, and distributes agricultural fertilizers and soil amendments. Buying fertilizers can be expensive and confusing. We help our customers navigate a very challenging supply chain.

We work with some of the world’s most reputable producers. We have sold over one million tons of fertilizer from over 20 unique countries. Understanding how our products are manufactured and used in the field is a key differentiator. We give our customers total logistics solutions from the mine to the factory and from the factory to the warehouse. We own a licensed customs brokerage and have over 40 approved fertilizer product licenses.

Our overall mission is to build strong and enduring relationships with our customers and suppliers to promote growth and education in the Thai agricultural sector.  The keys to our success are a customer-focused approach, consistent access to high-quality raw materials and on-the-ground warehousing and logistics.

“Some people, when they do someone a favor, are always looking for a chance to call it in.

And some aren’t, but they’re still aware of it—still regard it as a debt. But others don’t even do that.

They’re like a vine that produces grapes without looking for anything in return. . . after helping others. . .They just go on to something else. . . We should be like that.”
