Before you publish: Washington and federal rules

A few rules apply to any Black Diamond business that sells or advertises online:

• Fake or bought reviews are illegal under a federal rule in force since 2024 (16 CFR Part 465): post only real ones. 16 CFR Part 465
• Many Washington cities license businesses, and those city licences are added to the state business license as endorsements, each with its own fee and extra processing time. In Black Diamond, that means asking King County and the City of Black Diamond. Official source
• Washington’s state retail sales tax rate is 6.5%, with a local rate added depending on the city or county. Washington State Department of Revenue
• Under the Americans with Disabilities Act, businesses open to the public must make their goods and services accessible to people with disabilities, and the Justice Department’s guidance says that includes their websites. ADA.gov guidance
• Doing business under a name other than the owner’s full legal name is one of the conditions that requires a Washington state business license, so the trade name is registered together with that license at the Department of Revenue. Official source

Rules change and details vary by business; this is general information, not legal advice.
