UNSPSC 12164601: Sizing agent

A substance that is applied to fibers during paper manufacture in order to curb their tendency to absorb liquids by capillary action thereby keeping the ink on the surface of the paper where it was intended to remain.

UNSPSC 12164601 Sizing agent is a Commodity code covering chemical additives used to coat or treat fabric, paper, and other materials to improve their handling properties, water resistance, and finish. State and local governments procure sizing agents primarily through school districts, vocational education programs, and community colleges that operate textile labs, printmaking facilities, and paper-arts studios, as well as through county facilities departments managing fabric treatments for upholstery and custodial operations. The code also sees occasional activity from state departments overseeing correctional industries programs and manufacturing training centers that use sizing agents in production workflows.

The source contains no recent state and local contract opportunities tagged to this code. Without posted RFPs, RFQs, IFBs, or ITBs naming issuing bodies, response dates, or scope details, no geographic concentration or representative solicitations can be identified. This may reflect low procurement volume under the code, reliance on standing cooperative purchasing agreements for chemical supplies, or mis-tagging of opportunities to adjacent codes covering broader industrial chemicals or fabric treatments. Firms pursuing activity in this space should monitor school district and community college purchasing notices under textile, arts, and vocational equipment categories, as sizing agent solicitations may appear under parent-code 12164600 Industrial chemicals or general fabric-treatment supply codes rather than this specific commodity designation.
