Bureau of Industry and Security — Website: https://www.bis.doc.gov

Note: The Wikipedia source explicitly lists the Bureau of Industry and Security's website as 'www.bis.doc.gov', which matches the claimed URL https://www.bis.doc.gov. The differences in protocol (http/https) and www prefix are formatting variations that refer to the same canonical domain under the Department of Commerce, as noted in the additional context. The source directly confirms the domain.
