Testimonials

Trusted by Industry Leaders Worldwide

From European marine biofuel blenders to global automotive manufacturers, see why top procurement managers rely on Diamond Cashew Products for unwavering quality, batch after batch.

Securing a reliable, ISCC-certified supplier for marine biofuel feedstocks was a major hurdle for us until we partnered with Diamond Cashew Products. Their Degummed CNSL is exceptionally stable, and their ability to consistently ship bulk ISO tanks to Europe has made our transition to net-zero shipping completely seamless.

Lars Knudsen

The batch-to-batch consistency of their Phenalkamine epoxy hardeners is simply unmatched. We require extreme low-temperature curing and high salt-water resistance for our heavy-duty marine paints, and Diamond Cashew delivers every single time. Their ISO-certified quality control gives our QA team complete peace of mind.

Sarah Jenkins

In the automotive brake pad industry, raw material stability is critical for safety. We use Diamond Cashew's Friction Dust across our entire line of commercial brake linings. Not only is the thermal resistance superior, but their massive 3,000+ MT monthly production capacity ensures our manufacturing plants never face supply chain bottlenecks.

Hiroshi Tanaka

As an international chemical distributor, we deal with dozens of manufacturers, but Dr. Thirumurugan's team at Diamond Cashew stands in a league of their own. Their continuous distillation technology yields an incredibly pure product, and their export team makes shipping from the Chennai port to our facilities completely frictionless. Highly recommended.
