Mississippi to South Carolina: master plumber license reciprocity
Mississippi does not issue a statewide master plumber license, so there is nothing to transfer. Here is South Carolina's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Licensure by examination with credit for out-of-state experience (states without a PB waiver exam)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A plumbing contractor from a state (or classification) whose exam is not listed for PB on the Board's waiver list is told: 'you are not eligible for waiver/reciprocity. You will be required to take the SC exams.' The applicant passes the South Carolina Plumbing technical exam through PSI and the South Carolina Business Management & Law for Commercial Contractors exam, then files the Qualifying Party application (Doc. 168) with proof of at least 2 years of full-time work experience performed within the past 5 years in the plumbing classification, which may have been earned in any state and should primarily reflect commercial work (a PHCC Academy of North Carolina apprenticeship certificate covering plumbing is an alternative). The business files the Mechanical Contractor license application with the $350 licensure fee and a financial statement (or surety bond) meeting the group limit it wants. Section 40-11-290 separately allows the Board to exempt the technical exam for an applicant who verifies passing an essentially identical exam in another state even without a reciprocal agreement, but the Board's published waiver list and instructions do not describe a process for invoking it outside the listed exams. Ohio, Georgia and other states named on the cover of the 2019 waiver PDF are not treated as plumbing Reciprocity partners here because no PB exam mapping was recorded on the extract used for this file.
PSI exam fees are paid directly to PSI and are not published on LLR's pages. The Board's licensure page shows a $350 licensure fee but no separate qualifying-party application fee. The current Mechanical Group financial thresholds on the licensure page (Group 2: $100,000 per job, $10,000 working capital or $15,000 net worth, $15,000 bond) differ from the 2019 waiver document's table; the web page is treated as current. Typical timeline is an estimate; LLR publishes no processing time. Residential specialty plumber fees and exam-waiver states were not confirmed (resplumb.aspx blocked).

How South Carolina licenses master plumbers
South Carolina master plumber · “Mechanical Contractor, Plumbing (PB) classification - Qualifying Party certification”
Statewide license
South Carolina has no license titled 'master plumber'. The highest person-held plumbing credential is the Contractor's Licensing Board's Qualifying Party certification in the Plumbing (PB) classification of the Mechanical Contractor license. The individual passes the South Carolina plumbing technical exam through PSI (unless a listed waiver exam applies) and the South Carolina Business Management & Law for Commercial Contractors exam, documents two years of full-time experience within the past five years in the classification (or a PHCC Academy of North Carolina plumbing apprenticeship certificate), and is certified as the qualifying party for a licensed entity (which may be a sole proprietorship). The certification stays with the person; Doc. 168 states the certified qualifying party 'is not a licensed contractor' and the entity holds the license. The license fee is $350, with a financial statement or surety bond sized by mechanical group (Group 2, jobs to $100,000: working capital $10,000 or net worth $15,000, or a $15,000 bond). Work over $10,000 requires this license under § 40-11-30. Licensees from other states take the South Carolina plumbing technical exam and the Business Management & Law exam.
Why Mississippi has nothing to transfer
Mississippi master plumber
Licensed by cities and counties
Mississippi does not issue a personal master plumber license. The state-level plumbing credential is the Mississippi State Board of Contractors (MSBOC) contractor license: the commercial Mechanical major classification or its 'Plumbing (Test Required)' specialty (required on commercial jobs over $50,000; application and renewal $400, $300,000/$600,000 liability insurance, CPA-reviewed financial statement showing $50,000 net worth for Mechanical or $20,000 for the Plumbing specialty) or Residential Plumbing / Residential Mechanical (required for residential plumbing subcontracting over $10,000 in remodeling or $50,000 new construction; application $50, renewal $100). The license is issued to the business through a Certificate of Responsibility with a named qualifying party who passes the open-book PSI Plumbing (or Residential Plumbing) trade exam and the mandatory Mississippi Law and Business Management exam, so a master plumber who only wants to work for an employer has nothing to transfer to at the state level; the personal master credential exists only in cities such as Southaven (Master trade license, $100, which itself requires an active MSBOC license, a $10,000 bond and liability insurance) and Gulfport (contractor license issued to the qualifying party, $100). MSBOC waives its plumbing trade exam, for $50 per exam, for qualifying parties who hold a current license obtained by examination from the Alabama Plumbers and Gas Fitters Examining Board (commercial Plumbing exam only), the Ohio Construction Industry Licensing Board (Plumbing), the South Carolina Residential Builders Commission (Residential Plumbing, no discipline in three years) or the Tennessee Board for Licensing Contractors (all exams, no discipline in the last year); the Alabama General Contractors Board, Arkansas and Louisiana agreements expressly exclude plumbing, and the Business and Law exam is never waived.
How local licensing works in Mississippi
State contractor license (business). MSBOC issues commercial and residential contractor licenses to companies through a Certificate of Responsibility. The commercial Mechanical major classification 'involves all aspects of heating, cooling, refrigeration and associated equipment piping and ductwork as well as plumbing work' and carries 15 specialties including Plumbing, Process Piping, Underground Utilities, Fueling Systems and Irrigation Systems (all test required); an applicant may instead take only the Plumbing specialty. The qualifying party (owner, officer or responsible managing employee) passes the PSI open-book trade exam and the Mississippi Law and Business Management exam; fees are $400 application ($400 annual renewal, $100 per additional classification), general liability insurance of $300,000 per occurrence / $600,000 aggregate, and a CPA-reviewed financial statement showing net worth of $50,000 for a major classification or $20,000 for a specialty. Residential Plumbing (Residential Plumbing exam) and Residential Mechanical (Residential HVAC and Residential Plumbing exams) require the Law and Business exam, a $50 application fee ($100 per additional classification, $100 renewal) and proof of liability insurance with no minimum.
MSBOC exam waivers for out-of-state qualifying parties. Reciprocity 'applies to waiver of a trade exam requirement only' ($50 per exam waived, plus a $25 verification fee) after the origin board completes MSBOC's Reciprocity Verification Form; the applicant must have held the origin license for one year and passed that board's exam. Plumbing waivers are available for the Alabama Plumbers and Gas Fitters Examining Board (commercial Plumbing exam only; current license, Alabama exam taken), Ohio CILB (Plumbing; no discipline in the last year), the South Carolina Residential Builders Commission (Residential Plumbing; no discipline in three years) and Tennessee ('the only state that waives Mechanical and Plumbing'; no discipline in the last year). The Alabama General Contractors Board entry waives 'all exams but Mechanical & Plumbing', Arkansas excludes 'any type of Mechanical (i.e. Plumbing, Boilers, Process Piping, HVAC)', and Louisiana 'CAN WAIVE HVAC BUT NOT MECHANICAL OR PLUMBING'; Georgia, North Carolina, the South Carolina Contractors Licensing Board, Florida and California agreements do not reach plumbing. Separately, Form UROL under the Universal Recognition of Occupational Licenses Act (Miss. Code 73-50-2) waives the trade exam for an individual who has established Mississippi residency and held a similar license in any state for at least one year, and the Military Family Freedom Act (73-50-1) applies to military members and families. Every path still requires the Business and Law exam and full application review.
Southaven. Master trade license $100: application, photo ID of the license qualifier, certificate of liability insurance, a $10,000 general surety bond in favor of the city, an active MSBOC contractor's license certificate and the company EIN. An out-of-state applicant without an MSBOC license must provide a letter of good standing from a municipality where their license is active and may not take residential projects or commercial projects over $50,000; reciprocity questions are referred to MSBOC. Confirmed for mechanical and electrical on 2026-09-15; the plumbing card was not separately confirmed because the form could not be reopened on 2026-09-16.
Gulfport. Contractor license issued to the qualifying party ($100, waived with an MSBOC Certificate of Responsibility): notarized application, current MSBOC license if any, five reference letters (waived with an MSBOC license), $100,000/$300,000 liability insurance naming the city, home-jurisdiction privilege license and photo ID. No reciprocity provision.
