What does the symbol on the bottom of the stainless steel water cup mean?Is it required by the national standard? (one)

When you buy stainless steel water cups every day, you will notice that there is a shield-shaped icon at the bottom of the water cup. There will be a number of 304 or 316 in the icon. What does this picture and number mean? Does the domestic quality inspection agency or the international quality inspection require that each stainless steel water cup must be marked with these icons?

First of all, the editor explains the meaning of the shield icon 304 or 316.304 indicates that the water cup liner is made of 304 stainless steel, and 316 indicates that the water cup liner is made of 316 stainless steel.The editor of 304 stainless steel and 316 stainless steel has been explained in detail in the previous articles. If you have any unclear friends, please refer to the previous article of the editor.

Secondly, as for the shield-shaped icon with a number symbol, no country in China or the world requires it to be marked.The beginning of this conformity comes from the fact that the brand commissioned the water cup factory to produce it, hoping to create more selling points, and then deliberately processed it by stamping.Therefore, consumers do not need to believe that the water cup with the icon actually uses these materials just because the other party marked it as 304 or 316.

Some friends have paid attention to the previous statement of the editor, saying that the stamped water cup only indicates that the inner liner of the water cup is made of these materials, why not say that the whole body of the cup is made of this material?As a member of a strict stainless steel drinking cup production factory, the editor will explain to you seriously and responsibly based on professional ethics and a pragmatic attitude.Yes, if an icon is stamped on the bottom of the stainless steel liner, please first believe that the other party only uses this material for the liner. Why do you say that?
