PSC 6840

Overview

The Product and Service Code (PSC) system is the federal government’s standard taxonomy for classifying what is bought on contract actions. Agencies report PSCs in FPDS and related acquisition systems to identify the predominant product or service procured, enabling spend tracking, analysis, and reporting. The PSC Manual provides definitions, inclusions/exclusions, and coding guidance. ¹

PSC 6840 covers “Pest Control Agents and Disinfectants.” The PSC Manual lists insect repellents, fungicides, insecticides, rodenticides, and weed killers as included items; it explicitly excludes personal deodorants. It appears in Federal Supply Group 68, “Chemicals and Chemical Products,” and is selected when those items are the predominant product on the action. ¹

What this PSC covers

• Insect repellents intended for pest deterrence in facilities, field, or operational settings. ¹
• Fungicides and related agents for controlling fungal growth on surfaces or environments. ¹
• Insecticides for crawling or flying pests, including formulations prepared for application. ¹
• Rodenticides used for controlling mice, rats, and other rodent pests. ¹
• Herbicides/weed killers for vegetation management. ¹
• General disinfectant agents used to reduce or eliminate microorganisms on nonliving surfaces. ¹

Classification guidance and boundaries

• The Group 68 note directs that individual, nonmedicinal chemical elements/compounds are generally classified in 6810, while mixtures or chemicals prepared in a vehicle are classified by use; for example, DDT (compound) is 6810, but DDT liquid spray (an insecticide) is 6840. ¹
• Items bearing nonchemical names such as BLEACH or INSECTICIDE are typically classified by use rather than composition; corresponding chemical compounds (e.g., sodium hypochlorite solution) fall in 6810. Medicinal chemicals go to 6505 and in vitro diagnostic reagents to 6550. ¹
• 6840 excludes personal deodorants; related specialty chemicals that are not pest control agents or disinfectants are generally placed in 6850. ¹

DoD coordinated acquisition (PGI 208.7006)

For DoD, contracting responsibility for 6840 items is assigned to DLA’s Defense Supply Center Richmond (DSCR) under the Coordinated Acquisition Program. This PGI table distinguishes assignments across supply classes for centralized procurement. ²

Regulatory and compliance context

• Pesticides (including insecticides, herbicides, rodenticides, and many antimicrobials) must be registered by EPA before sale or distribution in the U.S., unless they meet a minimum-risk exemption; labels are legal directions for use. These requirements frequently underpin specifications and compliance checks in procurements coded under 6840. ³
• EPA’s pesticide registration program evaluates active and inert ingredients, use patterns, and risk to human health and the environment; registration decisions and labeling control lawful marketing and use. ⁴

Frequently asked questions

• What products are typically purchased under PSC 6840?
  Insect repellents, fungicides, insecticides, rodenticides, weed killers, and disinfectant agents, when these items are the predominant buy on the action. Personal deodorants are excluded. ¹

• How is PSC 6840 different from PSC 6810?
  6810 is for individual, nonmedicinal chemical elements/compounds; mixtures or preparations classified by use go elsewhere. Thus, a pure compound may be 6810, while a formulated insecticide spray is 6840. ¹

• Are pesticides/disinfectants under PSC 6840 required to be EPA-registered?
  EPA requires registration for pesticides sold or distributed in the U.S., with limited exemptions for certain minimum-risk products; registered labels govern lawful use. Many pest control agents and antimicrobial pesticides procured under 6840 fall under this regime. ³

• Which DoD buying activity manages PSC 6840?
  Under DFARS PGI 208.7006, 6840 is assigned to the Defense Supply Center Richmond (DSCR) for coordinated acquisition across DoD. ²

• Is there an official NAICS crosswalk for PSC 6840?
  Not specified by official sources ¹.
