After an active constituent is approved or a chemical product is registered there are a number of ways to make changes depending on the type of information you are changing and whether it is relevant.
Those who are liable to pay levy on a product should be aware of their obligation to provide the Australian Pesticides and Veterinary Medicines Authority (APVMA) with a return stating the quantity of product subject to leviable disposal.
Product holders are also required to complete a declaration of leviable values each year.
