Indiana to Minnesota: journeyman plumber license reciprocity
Minnesota has no reciprocity agreement with Indiana. Your Indiana experience counts toward eligibility, but you must pass the Minnesota exam.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state journeyman without a reciprocity agreement (exam required; license substitutes for experience documentation)
Nothing is waived, but your documented out-of-state hours count toward eligibility to sit the exam.
A journeyman plumber licensed anywhere other than North Dakota or South Dakota gets no exam waiver and must pass the Minnesota journeyworker written exam. The out-of-state license does carry weight: DLI's exam-eligibility list accepts 'a current plumber's license from another state where the licensing jurisdiction requires at least four years of practical plumbing experience and an examination to qualify for licensure' as a stand-alone qualification to sit the exam, so a licensee from such a state need not re-document 7,000 hours. Applicants whose state does not meet that test rely on documented hours instead, and DLI caps out-of-state experience at two years unless the applicant first obtained a plumber's license in that state; out-of-state apprenticeship hours count when certified by the state agency that regulates plumbing there. The applicant applies through iMS with the $50 exam fee, must wait 30 days to reapply after a failed attempt, and pays the license fee after passing. Minnesota has no separate law or business exam for individual plumbers.
DLI pages describe no endorsement route for non-reciprocal states; the only exam waiver is the North Dakota / South Dakota reciprocity. The initial license fee amount is not published on the pages fetched (DLI says instructions are given after the exam is passed; the fee schedule statute, Minn. Stat. Whether a city-issued origin license from a state without statewide licensing satisfies the 'license from another state' route is not addressed; DLI's wording is 'licensing jurisdiction', but the reciprocity page expressly rejects city-obtained licenses, so this file treats municipal origin licenses as not accepted.

How Minnesota licenses journeyman plumbers
Minnesota journeyman plumber · “Journeyworker Plumber”
Statewide license
Issued by Minnesota Department of Labor and Industry (DLI), Plumbing Board
Minnesota issues a statewide Journeyworker Plumber license through the Department of Labor and Industry (DLI); DLI's license-types page states the license 'authorizes the individual to work statewide', and no city-issued plumber licenses appear on DLI's pages (DLI also issues a Restricted Journeyworker license limited to towns under 5,000). A new applicant must first pass DLI's written journeyworker exam ($50 exam fee), and is eligible to sit it after a registered apprenticeship, four years (1,750 hours per year, 7,000 hours) of practical experience as a DLI-registered unlicensed plumber (Minn. Stat. 326B.47, subd. 2), two years under a Minnesota restricted license, or by holding a current plumber's license from another state that requires at least four years of experience and an exam. Journeyworker plumbers licensed by examination in North Dakota or South Dakota may be licensed without the Minnesota exam under DLI's reciprocity page. Licenses expire December 31 of odd-numbered years; renewal is $53 and requires 16 hours of continuing education, at least eight on the State Plumbing Code (2020 Minnesota Plumbing Code, Minn. R. ch. 4714).
