Buyer questions

FAQ for faster qualification

Can Wisdomray support equivalent model matching?

For this classroom build, the site presents model matching and datasheet request paths as positive assumptions. Formal publication needs confirmed product files.

Can certificates or compliance documents be shown?

The page may show quality workflow placeholders for the exercise. Real certificates, logos, and certificate numbers must be verified before publishing.

What should buyers send for a fast RFQ?

Product category, package or model, application, quantity, destination country, email, and WhatsApp are the minimum useful fields.
