South Dakota Inland Marine Insurance and the Filing Exception

SDCL 58-24-10 requires rate filings and then says the section does not apply to inland marine risks which by general custom are not written according to manual rates or rating plans. Section 58-24-25 says no insurer shall issue a contract except in accordance with filings in effect, and then says that section does not apply to inland marine risks as to which filings are not required. A non-filed class can still exclude the loss you care about.

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 to Watch for With Inland Marine in South Dakota

Only Non-Manual Inland Marine Skips the Rate Filing
Section 58-24-10's exception is for inland marine risks which by general custom of the business are not written according to manual rates or rating plans. If a manual exists for contractors' equipment or a trip transit class, do not assume the exception applies. Ask which manual, if any, was used. ¹
The No-Filing Issue Ban Has the Same Inland Marine Carve-Out
Section 58-24-25 generally bars an insurer from issuing a contract except in accordance with filings in effect under the chapter. It then says the section shall not apply to contracts for inland marine risks as to which filings are not required. That carve-out follows the filing exception. It does not approve a coverage term. ²
Ask Whether a Specific Rate Had to Be Filed
Section 58-24-14 addresses filing of specific rates. Read it with the two exceptions rather than as a second exemption for every floater. If the broker says the policy was not filed, ask whether the risk is the non-manual kind in § 58-24-10 or a specifically rated risk that still had to be filed. ^3,¹

Which Inland Marine Providers Have South Dakota 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 South Dakota. 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. ¹⁴
TechInsurance arranges inland marine coverage for contractors’ tools and equipment.
