The GHS information provided by 1 company from 1 notification to the ECHA C&L Inventory.

Section 8(a) of TSCA requires manufacturers of this chemical substance to report preliminary assessment information concerned with production, use, and exposure to EPA as cited in the preamble in 51 FR 41329.

Pursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. /4a(4H)-Dibenzofurancarboxaldehyde,1,5a,6,9,9a,9b-hexahydro/ is included on this list.

As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Bis(2-butylene)tetrahydro-2-furaldehyde is found on List C. Case No: 3127; Pesticide type: insecticide; Case Status: No products containing the pesticide are actively registered ... The case /is characterized/ as "cancelled." Under FIFRA, pesticide producers may voluntarily cancel their registered products. EPA also may cancel pesticide registrations if registrants fail to pay required fees or make/meet certain reregistration commitments, or if EPA reaches findings of unreasonable adverse effects.; Active ingredient (AI): Bis(2-butylene)tetrahydro-2-furaldehyde; AI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled."

Used as insect repellent; No longer registered with the EPA for use in the US, cancelled; [HSDB]

The active ingredient is no longer contained in any registered pesticide products ... "cancelled."

4a(4H)-Dibenzofurancarboxaldehyde, 1,5a,6,9,9a,9b-hexahydro-: ACTIVE

IT IS AN INSECT REPELLENT EFFECTIVE AGAINST COCKROACHES, STABLE & HORN FLIES, MOSQUITOES & GNATS. ITS MAIN USES NOW ARE IN PET SPRAYS & IN REPELLENTS FOR PERSONAL USE IN COMBINATION WITH OTHER MATERIALS. IT IS NO LONGER RECOMMENDED FOR USE ON MILK- OR MEAT-PRODUCING ANIMALS.

The pesticide is no longer an active ingredient in any registered pesticide products. Therefore, EPA is characterizing it as cancelled.
