Our store will automatically charge and withhold the applicable sales tax for orders to be delivered to addresses within the same state/province where Base Lab Tools Inc holds a presence. For orders shipped to other areas, you (the shopper) are solely responsible for any sales taxes and/or other taxes that may apply. If you are in the same state where Base Lab Tools Inc holds presence and have a resale certificate, Base Lab Tools Inc can set you up so your web sales are not charged sales tax. Contact one of our sales representatives if this applies to you.
