Does this apply to your product?

It likely does if you can answer yes to each of these:

  • Is it a water bottle or similar drinking vessel?
  • Is the body made of plastic, such as polypropylene?
  • Is it double-walled and insulated without a vacuum?

A no to any of them can mean a different code. A licensed broker can classify your product.
