Montana Supply Bond

Montana's Procurement Act (Mont. Code Ann. § 18-4-312) expressly gives state procurement departments discretion to require security — including a surety bond — on supply and services contracts, but does not mandate it. No other Montana statute creates a blanket supply-bond requirement; coverage is determined contract by contract based on risk.

About this bond

What a supply bond is

A supply bond guarantees a supplier will deliver materials or equipment as the contract says. Public agencies and project owners use them on large supply contracts.

Montana's Procurement Act (Mont.

  • § 18-4-312 states the department 'may in its discretion require' bid security, contract performance security, or both — the word 'may' means it is not mandatory.
  • Acceptable security forms include a surety bond from a licensed company, irrevocable letter of credit, U.S. currency, or certain bank-issued negotiable instruments.
  • The department may not require that a bond be furnished by a specific surety company or insurance producer.
  • Payment bonds required under § 18-2-201 cover material suppliers on public construction contracts, but those are construction payment bonds, not standalone supply bonds.

You need this bond if you're

What the surety looks at

Your business, credit and the supply contract. Large contracts can need financial statements.

FAQs

Common questions.

Does Montana law require supply bonds?

Usually the contract or the buying agency sets it, not a statewide law. The bid or contract documents state the amount.

What does it cost?

You pay a premium, not the bond amount. The surety sets the premium after it reviews your application, usually as a percentage of the bond amount. We show you the terms before you commit.
