It also includes any inert ingredient contained in the plant, or produce thereof.
Released for shipment. A product becomes released for shipment when the producer has packaged and labeled it in the manner in which it will be distributed or sold, or has stored it in an area where finished products are ordinarily held for shipment. Products stored in an area where finished products are ordinarily held for shipment, but which are not intended to be released for shipment must be physically separated and marked as not yet released for shipment. Once a product becomes released for shipment, the product remains in the condition of being released for shipment unless subsequent activities, such as relabeling or repackaging, constitute production.
Residential use means use of a pesticide directly:
(1) On humans or pets,
(2) In, on, or around any structure, vehicle, article, surface, or area associated with the household, including but not limited to areas such as non-agricultural outbuildings, non-commercial greenhouses, pleasure boats and recreational vehicles, or

Products and substances listed in this section are excluded from FIFRA regulation if they meet the specified conditions or criteria.
(a) Liquid chemical sterilants. A liquid chemical sterilant product is not a pesticide under section 2(u) of FIFRA if it meets all of the following criteria. Excluded products are regulated by the Food and Drug Administration (FDA). Products excluded are those meeting all of the following criteria:
(1) Composition. The product must be in liquid form as sold or distributed. Pressurized gases or products in dry or semi-solid form are not excluded by this provision. Ethylene oxide products are not liquid products and are not excluded by this provision.
(2) Claims. The product must bear a sterilant claim, or a sterilant plus subordinate level disinfection claim. Products that bear antimicrobial claims solely at a level less than “sterilant” are not excluded and are jointly regulated by EPA and FDA.
(3) Use site. (i) The product must be intended and labeled only for use on “critical or semi-critical devices.” A “critical device” is any device which is introduced directly into the human body, either into or in contact with the bloodstream or normally sterile areas of the body. A semi-critical device is any device which contacts intact mucous membranes but which does not ordinarily penetrate the blood barrier or otherwise enter normally sterile areas of the body.
(ii) Liquid chemical sterilants that bear claims solely for use on non-critical medical devices are jointly regulated by EPA and FDA.
(iii) Liquid chemical sterilants that bear claims solely for use on sites that are not medical devices, such as veterinary equipment, are not excluded and are regulated solely by EPA.
(b) Nitrogen stabilizers. A nitrogen stabilizer is excluded from regulation under FIFRA if it is a substance (or mixture of substances), meeting all of the following criteria:
(1) The substance prevents or hinders the process of nitrification, denitrification, ammonia volatilization, or urease production through action affecting soil bacteria and is distributed and sold solely for those purposes and no other pesticidal purposes. For purposes of this section, living organisms are not considered to be substances, and the actions of living organisms are not relevant to whether a substance is deemed to be a nitrogen stabilizer.
(2) The substance was in “commercial agronomic use” in the United States before January 1, 1992. EPA considers a substance to be in commercial agronomic use if it is available for sale or distribution to users for direct agronomic benefit, as opposed to limited research, experimental or demonstration use.
(3) The substance was not registered under FIFRA before January 1, 1992.
(4) Since January 1, 1992, the distributor or seller has made no claim that the product prevents or hinders the process of nitrification, denitrification, ammonia volatilization or urease production. EPA considers any of the following claims (or their equivalents) to be a claim that the product prevents or hinders nitrification, denitrification, ammonia volatilization or urease production:
(i) Improves crop utilization of applied nitrogen.
(ii) Reduces leaching of applied nitrogen or reduces groundwater nitrogen contamination.
(iii) Prevents nitrogen loss.
(iv) Prolongs availability of nitrogen.
(v) Increases nitrogen uptake, availability, usage, or efficiency.
(5) A product will be considered to have met the criterion of paragraph (b)(4) of this section that no nitrogen stabilization claim has been made if:
(i) The nitrogen stabilization claim, in whatever terms expressed, is made solely in compliance with a State requirement to include the claim in materials required to be submitted to a State legislative or regulatory authority, or in the labeling or other literature accompanying the product; and
(ii) The State requirement to include the claim was in effect both before the product bearing the claim was introduced into commercial agronomic use, and before the effective date of this rule.
(6) A product that meets all of the criteria of this paragraph with respect to one State is not thereby excluded from FIFRA regulation if distributed and sold in another State whose nitrogen stabilization statement requirement does not meet the requirements of paragraph (b)(5)(ii) of this section.
(c) Human drugs. Fungi, bacteria, viruses or other microorganisms in or on living man are not “pests” as defined in section 2(t) of FIFRA. Products intended and labeled for use against such organisms are human drugs subject to regulation by the FDA under the FFDCA.
(d) Animal drugs. (1) Fungi, viruses, bacteria or other microorganisms on or in living animals are not “pests” under section 2(t) of FIFRA. Products intended for use against such organisms are “animal drugs” regulated by the FDA under the FFDCA.
(2) A “new animal drug” as defined in section 201(w) of the FFDCA, or an animal drug that FDA has determined is not a “new animal drug” is not a pesticide under section 2(u) of FIFRA. Animal drugs are regulated by the FDA under the FFDCA.
(e) Animal feeds. An animal feed containing a new animal drug is not a pesticide under section 2(u) of FIFRA. An animal feed containing a new animal drug is subject to regulation by the FDA under the FFDCA.
(f) Vitamin hormone products. A product consisting of a mixture of plant hormones, plant nutrients, inoculants, or soil amendments is not a “plant regulator” under section 2(v) of FIFRA, provided it meets the following criteria:
(1) The product, in the undiluted package concentration at which it is distributed or sold, meets the criteria of § 156.62 of this chapter for Toxicity Category III or IV; and
(2) The product is not intended for use on food crop sites, and is labeled accordingly.
(g) Products intended to aid the growth of desirable plants. A product of any of the following types, intended only to aid the growth of desirable plants, is not a “plant regulator” under section 2(v) of FIFRA, and therefore is not a pesticide:
(1) A plant nutrient product, consisting of one or more macronutrients or micronutrient trace elements necessary to normal growth of plants and in a form readily usable by plants.
(2) A plant inoculant product consisting of microorganisms to be applied to the plant or soil for the purpose of enhancing the availability or uptake of plant nutrients through the root system.
(3) A soil amendment product containing a substance or substances intended for the purpose of improving soil characteristics favorable for plant growth.
A substance or article is not a pesticide, because it is not intended for use against “pests” as defined in § 152.5, if it is:
(a) A fertilizer product not containing a pesticide.
(b) A product intended to force bees from hives for the collection of honey crops.
A product that is not intended to prevent, destroy, repel, or mitigate a pest, or to defoliate, desiccate or regulate the growth of plants, is not considered to be a pesticide. The following types of products or articles are not considered to be pesticides unless a pesticidal claim is made on their labeling or in connection with their sale and distribution:
(a) Deodorizers, bleaches, and cleaning agents;
(b) Products not containing toxicants, intended only to attract pests for survey or detection purposes, and labeled accordingly;
(c) Products that are intended to exclude pests only by providing a physical barrier against pest access, and which contain no toxicants, such as certain pruning paints to trees.
No person may distribute or sell any pesticide product that is not registered under the Act, except as provided in §§ 152.20, 152.25, and 152.30. A pesticide is any substance (or mixture of substances) intended for a pesticidal purpose, i.e., use for the purpose of preventing, destroying, repelling, or mitigating any pest or use as a plant regulator, defoliant, or desiccant. A substance is considered to be intended for a pesticidal purpose, and thus to be a pesticide requiring registration, if:
(a) The person who distributes or sells the substance claims, states, or implies (by labeling or otherwise):
(1) That the substance (either by itself or in combination with any other substance) can or should be used as a pesticide; or
(2) That the substance consists of or contains an active ingredient and that it can be used to manufacture a pesticide; or
(b) The substance consists of or contains one or more active ingredients and has no significant commercially valuable use as distributed or sold other than (1) use for pesticidal purpose (by itself or in combination with any other substance), (2) use for manufacture of a pesticide; or
(c) The person who distributes or sells the substance has actual or constructive knowledge that the substance will be used, or is intended to be used, for a pesticidal purpose.
