When you purchase a product with us, we will keep you informed about any changes made to that product's datasheet by sending out an email notification called a Product Advisory Notice (PAN). This explains any updates such as target changes, changes in tested applications and species, or, in rare cases, removal of a product from our catalog due to quality issues.
Some PANs are informational to let you know about minor changes, while other PANs are more serious; in these cases we will offer you a free alternative product, or a full refund of the original order.
