American Automobile Insurance Company, part of the Allianz, has filed a rule filing in Maryland to formally withdraw from the Commercial Inland Marine market. The filing was submitted on January 21, 2026, with the withdrawal effective upon approval.

Under the plan, the insurer will cease writing new Commercial Inland Marine business after August 1, 2026, completing a full market exit for the line in the state. No policyholder counts or premium figures were disclosed in the filing.

The withdrawal filing is being submitted by Arch Underwriters Inc., which is authorized to act on American Automobile Insurance Company’s behalf. Distribution and regulatory coordination are handled through Allianz Commercial.

The filing does not involve rate changes or technology updates and reflects a strategic withdrawal, rather than a repricing or restructuring of the product. The move aligns with broader Allianz and Arch pullbacks in Maryland, as seen in other recent filings affecting commercial specialty lines.
