Huntington T. Block Insurance Agency

What Huntington T. Block Insurance Agency does

Huntington T. Block Insurance Agency, Inc. (HTB) is a Pennsylvania-domiciled managing general underwriter and insurance broker specializing in fine art and musical instrument coverage. Founded in 1962 and operating as a wholly-owned unit of Aon plc since 1992, HTB underwrites and distributes customized insurance programs for museums, art galleries, universities, corporate and personal collectors, conservators, artists, municipalities, classic car museums, musical instrument owners and dealers, and symphony orchestras. Its core technology consists of proprietary Fine Art Insurance policy forms — including the world's first 'wall-to-wall' fine art policy developed with the London insurance market — and a standalone Musical Instrument Insurance program, both characterized by all-risk, worldwide coverage including in-transit protection. The product portfolio extends into Commercial Insurance (D&O with Provenance Liability, Cyber, E&O, surety), Personal Insurance via Aon Private Risk Management, and add-on modules such as Exhibition Insurance and SHOWSTOPPERS Event Cancellation.

HTB operates a consultative, sales-led distribution model combining direct phone-based underwriting, an independent agent and broker channel, the AAM and AIC trade-association partnerships, and Aon's broader affinity network (Aon Programs, APRM). Revenue is generated through insurance brokerage commissions and managing general agent fees on policies placed with carrier partners including Chubb, AIG, Pure Insurance, and the London market. The firm holds US multi-state producer licenses (notably Texas #17489 and California #0825502), is licensed in all states, and has built a customer base exceeding 1,200 museums, 500+ galleries, and 5,000+ musical instrument owners. Multiple HTB staff members have received Risk & Insurance magazine's Power Broker Award in the Fine Arts category for more than ten consecutive years, reinforcing its positioning as the oldest and largest US MGU in the specialty fine art segment.
