The recall was initiated by the importer, Madar Corporation LTD, of the United Kingdom. The products were sold exclusively online at Amazon.com from July 2020 through July 2021. The recall was issued due to the product’s failure to meet child-resistant packaging requirements under the Poison Prevention Packaging Act (PPPA) and a violation of the Federal Hazardous Substances Act (FHSA) labeling requirements. As of the recall date, no injuries had been reported.

2. Affected Products
The recall involves biOrigins-branded sodium hydroxide products. The product was sold in 500-gram and 1-kilogram zip-top, silver bags.
