About HazCom Deadline
HazCom Deadline is a free tool that does one job and does it properly: OSHA's updated Hazard Communication Standard does not have one deadline. It has four, and which one binds you depends on two things: whether you produce chemicals or merely use them, and whether you are dealing with substances or mixtures. All four moved four months later on 15 January 2026. Pick your situation below to get your date, the exact paragraph of 29 CFR 1910.1200 it comes from, and what you may lawfully do in the meantime.
Why this exists
OSHA moved all four Hazard Communication compliance dates four months later on 15 January 2026. A great many guides, checklists and vendor pages still show the old dates and are now simply wrong. This page exists to be the one that is not, and to say plainly which paragraph of the regulation each date comes from so you can check it yourself.
Where the dates come from
Every date on this page is taken from 29 CFR 1910.1200(j) as amended by OSHA's final rule of 15 January 2026 (Federal Register document 2026-00653), and is verified against the text of the regulation currently in force as published by the Electronic Code of Federal Regulations. The page also shows the superseded date for each paragraph, so that a further extension would be visible rather than silent. Nothing you select is sent to a server: the page runs entirely in your browser.
What this page is and is not
These are the statutory compliance dates, quoted from the regulation. They are not estimates. What this page cannot do is tell you whether a particular chemical, product or workplace falls inside the standard, whether an exemption applies to you, or how a state-plan jurisdiction has adopted the rule. Those are the questions where you want a qualified safety or legal professional. If OSHA amends the standard again, the date here changes; that is checked against the regulation and the Federal Register rather than by memory.
