What Is AIG?
AIG is the marketing name for American International Group, Inc.; AIG says its insurance products are written or provided by subsidiaries or affiliates. Its U.S. business pages list commercial casualty, property, cyber, management and professional liability, and specialty programs, but a brand-level page does not identify the insurer for a particular policy. 1,2
What Is Harper Insurance?
Harper suits hard-to-place businesses such as contractors, care providers, manufacturers and transportation firms; standard small businesses seeking direct quotes should compare online carriers. Its workers’ compensation service helps classify payroll for audits. 4,5
What Is Commercial Property Insurance?
Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. 8,9,10
Key Differences in Commercial Property Insurance
Institutional property appetite and online quote intake
AIG cites hospitals, universities, and global manufacturing among its property audiences and says its engineers work with clients on mitigation. Harper’s intake lets a business select “My building, equipment, and inventory (property),” enter its state and revenue, and start a quote request. Harper lists all states and Washington, D.C. for intake but leaves eligibility to underwriting. A buyer can use Harper’s form to begin, while a larger portfolio should ask AIG’s broker about the relevant program and account-level services. 3 6
Replacement values and equipment breakdown
Harper summarizes commercial property as covering buildings, equipment, and inventory at replacement cost, and its manufacturing page pairs property with equipment breakdown for production lines and machinery. AIG describes physical-property protection against events such as storms, theft, and vandalism, with the policy setting actual terms. For a manufacturer, equipment breakdown and replacement valuation can materially change the claim calculation; request the forms, values, and machinery coverage rather than relying on the summaries. 3 7

AIG vs Harper: Commercial Property Insurance: documented features by provider
| Criteria | AIG Commercial Property and Retail Property | Harper Commercial Property Insurance |
|---|---|---|
| Role in This Line | AIG markets commercial property insurance and identifies Retail Property as a product area. For domestic and global corporate and risk-management clients, the page describes both risk-transfer insurance and non-risk-transfer fronting or captive solutions; those structures are not the same as an insurance policy issued by AIG. 3Company-reported. AIG’s U.S. Commercial Property page. It does not identify the insurer or fronting company for a particular buyer’s placement. | For commercial property, Harper describes calling the insurance companies that write the coverage and presenting the customer with the resulting options to choose from, rather than issuing a commercial property policy itself. 6Company-reported. Homepage 'What we cover' introduction and coverage list, where commercial property is one of the enumerated lines. |
| Issuing Insurer | Confirm in your quote. | Harper's public pages do not name the insurer or insurers that would underwrite a commercial property policy; the homepage shows an unlabeled panel of insurer logos it says it works with, describing the rest as 'specialists who cover the work the big names turn down.' 6Not publicly disclosed. Checked the homepage insurer-logo panel on 2026-09-23; no carrier names accompany the logos in the page text. |
| Who It’s For | AIG names businesses including hospitals, universities and global manufacturing among the varied organizations for which it has property options. The page does not provide a complete eligible-class list or state-by-state availability schedule. 3Company-reported. Illustrative customer types on AIG’s U.S. Commercial Property page; examples do not establish an applicant’s eligibility. | Harper's quote-intake form lists all 50 states and Washington, D.C. as selectable, indicating it takes commercial property quote requests nationwide, though eligibility for a specific building or business depends on underwriting review not described on the page. 6Company-reported. Homepage quote-intake state selector. |
| Coverage Features | AIG describes commercial property insurance as protecting business physical property against unexpected events such as storm damage, theft and vandalism, and says coverage can extend to certain work-related contents such as office equipment, furniture, fixtures and inventory. These are examples; actual coverage depends on the facts and each policy’s terms, conditions and exclusions. 3Company-reported. General property description on AIG’s product page, not a summary of a specific policy or all covered causes of loss. | Harper's homepage summarizes commercial property insurance as covering a business's buildings, equipment and inventory at what it costs to replace them. 6Company-reported. Homepage 'What we cover' blurb; the issued policy and declarations would control actual valuation method and terms. On its manufacturing industry page, Harper bundles property coverage with equipment breakdown, describing it as covering the building, the production line and machinery that cannot be down for a week. 7Company-reported. Manufacturing industry page; this is a manufacturer-specific bundle of property and equipment breakdown, not necessarily how Harper packages commercial property for other industries. |
| Limits and Retentions | The reviewed page does not state standard property limits, deductibles or retentions for a buyer. Confirm those amounts, covered causes and conditions in the quote and issued policy. 3Not publicly disclosed. AIG’s U.S. Commercial Property marketing page reviewed 2026-09-30; no buyer-specific quote or policy form was reviewed. | The reviewed pages do not publish commercial property limits, deductibles or valuation methods such as replacement cost versus actual cash value; those terms are not shown until a specific quote is issued. 6,7Not publicly disclosed. Checked the homepage and manufacturing industry page on 2026-09-23. |
| Risk Services | AIG says property risk engineers help clients identify and mitigate loss and that its engineers collaborate with clients on solutions tailored to risk factors. The page does not state that these services are included for every account or guarantee reduced losses. 3Company-reported. Company-described commercial property risk engineering; account-specific service availability is not stated. | Confirm in your quote. |
| How to Apply | Confirm in your quote. | You can start a commercial property quote through Harper's online intake by selecting the 'My building, equipment, and inventory (property)' checkbox alongside the business's state, estimated annual revenue and a description of what it does. 6Company-reported. Homepage quote-intake form. |
| Claims Support | AIG describes a dedicated Property claims team and a claims promise intended to enable prompt resolution. The page does not publish a service-level deadline or claim outcome guarantee. 3Company-reported. AIG’s company-reported general property claims description; no account-specific claims handling terms were reviewed. | Confirm in your quote. |
