## What Is Inland Marine Insurance?

If your business moves equipment between sites or ships goods, inland marine can cover those property exposures; installation and other forms address different property categories. Match the quote to what you own, rent or hold for others. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://www.dms.myflorida.com/content/download/132333/823484/SoF_Policy_CE_17-18_UM00056635MA17A.pdf "Inland Marine Policy: Contractors’ Equipment")

## Key Differences in Inland Marine Insurance

### Equipment Product and Package Category

Harper places inland marine as part of a combined Equipment Insurance product alongside owned-equipment property coverage and equipment breakdown, rather than as a separately named standalone product. THREE lists inland marine as a component of its combined Business Owners Policy. Ask Harper how the equipment package separates transit and breakdown risks, and ask THREE whether its quote includes a scheduled inland-marine section. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Transit, Jobsite, and Rented Equipment

Harper says the inland-marine portion covers equipment while in transit or on a jobsite, including rented or borrowed equipment for which the business is responsible. THREE names inland marine but does not describe comparable property categories in the reviewed record. Contractors should list owned and non-owned equipment, locations and values, then check both forms for transit, jobsite and rented-property protection. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

### Application Documents

Harper asks applicants to send an equipment list through its online quote form and says it prices the list across willing insurers. THREE offers online package quoting with licensed advisor help. Prepare serial numbers, replacement values and rental agreements, then ask both routes whether additional schedule details or security controls affect the quote. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") [4](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway")

## What to Confirm in Inland Marine Insurance Quotes

- Ask Harper which carrier and equipment breakdown terms apply; ask THREE to list each scheduled item and whether the package covers rental equipment in transit. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")
- Confirm deductibles, valuation basis, jobsite coverage, transit territory and protection for borrowed or rented equipment. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway")

## Offering Details

| Criteria | Harper Equipment and Inland Marine Insurance | THREE Business Owners Policy |
| --- | --- | --- |
| Role in This Line | Harper places inland marine coverage as part of a combined 'Equipment Insurance' product it sells alongside owned-equipment property coverage and equipment breakdown, rather than as a separately named standalone product page. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Company-reported; scope: Harper's equipment product page, the only page found for this line; the coverage directory and intake form separately label the same coverage 'tools and equipment that leave the shop (inland marine).'.) | THREE presents Inland Marine as a component of its combined Business Owners Policy rather than identifying it as a separate standalone policy on the reviewed product page. [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Company-described U.S. package structure. The page does not establish underwriting terms or that every listed category will be included for every applicant..) |
| Issuing Insurer | Confirm in your quote. | The linked sample policy's declarations identify Berkshire Hathaway Direct Insurance Company as issuer. [5](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the issuer named on the public sample only; the sample does not establish the issuing entity for every state-specific quote or buyer's issued policy..) |
| Who It’s For | Harper targets this coverage at businesses whose equipment or tools travel to jobsites or client locations rather than staying inside one building, since it frames the product around the gap left when equipment leaves the premises. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Company-reported; scope: Product-page framing; not an eligibility guarantee for a particular applicant or equipment type..) | The reviewed product page does not state separate eligibility rules for Inland Marine; the general quote and advisor route is not proof that a particular business qualifies for it. [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [4](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: Eligibility and state availability remain unestablished for an individual risk until THREE returns its quote and applicable forms..) |
| Coverage Features | Harper describes the inland marine portion of this product as covering equipment while it is in transit or on a jobsite, which it says standard property policies typically exclude once equipment leaves the business's premises. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Company-reported; scope: Product-page coverage summary; the issued policy and its exclusions control the actual terms..)<br><br>Harper says it can also place coverage for rented or borrowed equipment a business is responsible for but does not own, in addition to owned equipment in transit or on site. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Company-reported; scope: Product-page coverage-features list; availability and terms depend on the insurer and underwriting..) | THREE's Business Owners Policy page lists Inland Marine among its marketed coverage categories in the combined policy. This describes the product page, not whether the category appears in a particular quote or responds to a loss. [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: Official THREE package marketing for Inland Marine. The sample policy is state-selectable and does not establish that this item is included in every quote or issued policy..) |
| Limits and Retentions | The reviewed equipment page does not publish limit or valuation amounts for inland marine coverage; it says pricing and available terms depend on equipment values and where the equipment travels. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Not publicly disclosed; scope: Equipment product page as read on 2026-09-23..) | The reviewed public product page does not state a separate limit or deductible for Inland Marine; THREE says the quote-specific insurance summary lists limits and deductibles. [6](https://threeinsurance.com/business-owners-policy "Business Owners Policy - THREE by Berkshire Hathaway") [5](https://threeinsurance.com/the-policy "The Policy: 3 Jargon-free pages - THREE by Berkshire Hathaway") (Evidence: Not publicly disclosed; scope: No number is inferred from the sample policy. The quote and issued declarations control the buyer-specific limit and deductible..) |
| How to Apply | You apply by sending Harper an equipment list through its online quote form, which it says it prices across insurers willing to write that equipment. [3](https://www.harperinsure.com/coverages/equipment "Equipment Insurance") (Evidence: Company-reported; scope: Quote form and FAQ observed on the product page..) | THREE directs small-business prospects to an online quote and says licensed Small Business Advisors can help with the process. [4](https://threeinsurance.com/ "Jargon-free small business insurance - THREE by Berkshire Hathaway") (Evidence: Company-reported; scope: This is the route for the overall THREE product. It does not show whether Inland Marine will be offered for a particular business or whether a customer can bind that line without an issued policy..) |
