"Stainless" on a quotation is not evidence. What a buyer needs is a record that ties the material to the belt in the order, and a grade chosen for the actual line.
SUS304 and SUS316 are common choices, but neither is right for every line. Product contact, cleaning chemicals, moisture, salt and temperature all matter. We ask about them before recommending a grade, and the grade is confirmed on the drawing.
The line runs in steam and is cleaned with acid and alkaline agents. The customer specified 316 for chain, mesh and rods.

Covering the material of the belt in your order.
So the material is part of what you signed off.
For the order, when you ask for them.
A food application does not by itself mean a food-contact certification, and a grade does not confirm suitability for every environment. Materials and finish are confirmed for your line.
The product, the cleaning chemicals and how often the line is washed, the temperature range, and a drawing or photos of the current belt.
Yes, with every order.
It depends on the product, cleaning chemicals and temperature. We ask about them and confirm the grade on the drawing.
Pickling, passivation and electropolishing are handled separately and confirmed for each belt; not every option applies to every belt type.
Tell us the product, cleaning and temperature. Spring Liu, Sales Director, will reply with the questions engineering needs answered.
