A W9 is a tax form which certifies a company’s or individual’s tax identification number – for use when located and doing business legally in the United States.
You can download one from the IRS here.
It is the Goods and Sales Tax Number that Canadian companies get when located and doing business legally in Canada.
A license required by the Chinese Government for any company or individual located and doing business in China.
It really depends on the requirement of the local government department. Here are two scenarios that may help explain:
  1. Company ABC opens a new facility at the new address in the same area (close to each other) and the new address is just for production and it will not issue invoice, normally they do not need a new BRL, but they need to register their new address with their local government dept.
  2. Company ABC opens a new facility at the new address in the same area (close to each other) and the new address has a different name, a new BRL is required.
Yes. We will have the manufacturer sign an L-40 agreement as well as the Applicant, and for identity verification, credit collection and other purposes, we must have the manufacturer’s information.
UL requires a W9 or BRL with the legal name – and if there is a DBA involved, it should be stated next to the legal name.
