Missouri Inland Marine Insurance: Prepare for Renewal Changes

Missouri defines commercial property to include business inland marine. If an insurer raises a covered commercial policy's premium by more than 25 percent at renewal, § 379.321 generally requires at least 60 days' notice (30 days for umbrella or excess policies); the statute also provides a limited continuation remedy if notice is missed. The remedy has exceptions, including certain unpaid premiums and changes in operations, hazards or exposure basis. Review any changed equipment, locations and transit before renewal, and do not assume the notice rule preserves coverage for omitted or newly acquired property.

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. Read the national Tools, equipment and inland marine guide.

What Should You Watch for With Inland Marine Insurance in Missouri?

Treat business inland marine as commercial property for renewal review
Missouri expressly includes business inland marine within its commercial property definition for the notice provision. When reviewing a renewal, compare named property, values, locations, limits, deductibles and endorsements, not just the total premium. ²
Check the increase and the exceptions carefully
The notice rule is triggered by an increase greater than 25 percent and generally requires 60 days, with 30 days for umbrella or excess. The statute excludes certain premium differences caused by changes in operations, hazards or exposure basis and addresses nonpayment; ask the insurer to explain the calculation and notice date. ²
Do not assume a missed notice fixes a coverage gap
Any continuation remedy is limited by the statute and ends to the extent substantially duplicative replacement coverage starts. It does not add property or locations absent from the expiring contract, so reconcile new machines, jobsite moves and transit before expiration. ²

Which Inland Marine Insurance Providers Have Missouri License Records?

These providers publish a national listing for Tools, equipment and inland marine; the license records below name the licensed entities and roles. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Missouri. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

Specialty Program Group LLC
TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. ¹⁷

Surplus-Lines Tax and Stamping Office in Missouri

Reported tax rate. 5% of premium; Missouri taxes the entire gross premium when Missouri is the home state ^7,^8,^9,¹⁰

When Missouri is the insured’s home state, the state applies its 5% surplus-lines tax to the entire gross premium of a multistate policy; the regulator’s FAQ says the tax includes applicable fees. Eligible nonadmitted insurers do not participate in the Missouri Guaranty Fund, and Missouri generally requires the full amount or kind of coverage to be unavailable from admitted insurers before placement; an exempt commercial purchaser search exception has separate disclosure and written-request conditions.

What Should You Ask Before Buying Inland Marine Insurance in Missouri?

What is the renewal's percentage increase, notice date and stated basis for the change?
Which additions, deletions or location changes affect the scheduled values and premium?
Does the renewal keep rented gear, tools in transit, jobsite storage and loading/unloading within the same terms?
If notice is late, what specific statutory conditions apply and when does replacement coverage begin?
