What should businesses consider when choosing a Cheddar Cheese supplier?

I’m researching Cheddar Cheese suppliers for commercial requirements and wanted to know what factors others consider before choosing one.

I came across Vista Dairy, which supplies Cheddar Cheese and highlights food-safety certifications such as ISO, HACCP, GMP, and HALAL. The company also mentions international supply experience. (vistadairy.com)

For those who have purchased Cheddar Cheese in bulk, what matters most to you—quality, certifications, pricing, consistency, or supplier reliability?

Would appreciate your recommendations and experiences.
