Product rules, read at the source.

You name a product. Runstamp returns the rules that apply to it, each with a link to the law it comes from, and says plainly when a rule could not be checked.

It covers 2,189 rules of U.S. federal and state law, read from 295 sources.

The rules for one product sit in many places: statutes, agency lists and state registers, each on its own schedule. A seller finds out about a change when a notice arrives.

Runstamp reads those sources, across 21 markets, so a seller can look before the notice comes. Rules are current as of 31 Oct 2026.

Sellers with a few products, importers with a catalog to watch, and brands or agencies with several stores.
