The main purpose of the Destruction of Hazardous Imports Act is to give the Secretary of Health and Human Services more authority to destroy imported goods that pose a significant public health risk. This law aims to enhance public safety by ensuring that harmful products do not enter the market. Key provisions of the law include the ability for the Secretary to order the destruction of imported articles that have been denied entry due to health concerns. Once an order is issued, the owner or consignee of the article must destroy it within 90 days and cover the costs of destruction.
