Food-grade RFQs become vague very quickly when buyers stop at the phrase 'food belt'. For technical review, the useful question is not only whether the belt is clean or white, but how it touches product, how it is cleaned, and what the line expects from the surface.
The first checkpoint is contact condition. Direct contact with product, food packaging lines, and washdown-only lines lead to different material and documentation needs. Buyers should not compress them into one request if they want a useful answer.
The second checkpoint is process detail: covers, guides, cleats, slider beds, friction requirement, release behavior, and whether the belt only drives or also carries product. That package explains far more than a generic 'food conveyor belt' description.
The third checkpoint is cleaning logic. Water, detergent, temperature, frequency, and downtime expectation all affect whether a standard construction is enough or whether the line needs a more controlled fabricated PU solution.
