About Sompo International

Sompo International is a specialty insurance and reinsurance business within the wider Sompo group, which describes itself as a provider of property, casualty and specialty coverage. Group listings place its operations in the United States, the United Kingdom, several European countries, Bermuda, Singapore and Mexico. Retail and wholesale brokers and managing general underwriters distribute its products. The company says it writes both admitted and non-admitted business in the US, while its European business is underwritten through London-based and European subsidiaries.

Its website lists insurance lines including aviation, construction, energy, healthcare, marine, mercantile, professional services, real estate and transportation, along with a separate reinsurance unit covering property catastrophe, casualty, marine and energy, and workers' compensation. Claims handling is presented as a dedicated function that works alongside underwriters. In New York State, third-party business directories list offices in Purchase, New York City and New Hyde Park, and a Sompo group cargo-claims page gives a Manhattan address for its New York agent.
