(CNBC) — Amazon made sweeping changes to its terms of service for third-party sellers this week in an effort to address an issue that’s plagued the biggest piece of its e-commerce business.

As part of a settlement it reached with German antitrust authorities over its marketplace policies, Amazon said it will now give a 30-day notice to sellers facing suspensions and provide specific reasons to those who are blocked for “alleged legal infringements.” Until now, Amazon could terminate seller accounts at any time “without justification,” according to the agreement announced by The Federal Cartel Office of Germany.
