NIGP 310: Envelopes, Plain (see Classes 525, 615, 640, 655, 665, and 966 for Other Types)

NIGP 310 Envelopes, Plain (Class) spans custom-printed and stock commercial envelopes that state and local governments procure for utility billing, office operations, election administration, and internal communications. The code captures both specialty window envelopes (utility bill formats with barcode or window specifications) and standard No. 10 and 9" x 12" flat stock for general mailing and administrative use. Recent solicitations show governments buying envelopes through both single-vendor master agreements and split-award blanket purchase orders, often bundled with copy paper and printing services under consolidated office supplies contracts. Issuing bodies include cities (St. Petersburg, West Sacramento, Palm Bay, Tucson, Owensboro), counties (Cuyahoga County Board of Elections, Clay County, Marion County), school districts (Northside Independent School District, Parkway School District), state agencies (Texas Comptroller of Public Accounts, State of Maine Department of Administrative and Financial Services), and special-purpose boards (Cleveland Board of Elections). Cities and counties dominate the recent activity; school districts and boards of elections represent a secondary but consistent buyer category.

Geographic concentration appears in Florida (St. Petersburg, West Sacramento region, Palm Bay, Clay County, Marion County, Cuyahoga County in Ohio, and Texas through the Comptroller's statewide procurement), with additional activity in Maine and Kentucky. Representative recent opportunities include the City of St. Petersburg IFB26317 (office paper products including custom-printed utility bill envelopes and copy paper, bids due September 1, 2026, with SBE/MBE/WBE participation required and a three-year initial term plus two one-year renewals); the State of Maine RFQ10A26062300000000000324 (9" x 12" flat envelopes with poly window, estimated 330,000 annual units, quotations due August 11, 2026, one-year firm pricing with four optional renewals through 2031); the Cuyahoga County Board of Elections IFB 7158 (28,000 barcoded and non-barcoded provisional ballot envelopes, 70# white stock with barcode specifications, delivery by September 4, 2026); and the Texas Comptroller IFB 304T-26-310A1 (9,932 cases of No. 10 envelopes—4,966 windowless and 4,966 windowed—white wove, 30% recycled fiber minimum, delivery to Huntsville, bids due July 21, 2026, initial term through August 31, 2027 with four renewals). Cooperative purchasing through OMNIA Partners and state SmartBuy systems appears in larger multi-jurisdictional master agreements. Custom-printed items typically require sample submission for approval before production; delivery windows are tight (four to seven business days post-approval or purchase order). Insurance and bonding requirements are standard on municipal contracts; state and federal compliance provisions (Buy America, civil rights, Section 3 labor) appear in larger agreements and those with federal funding nexus.
