California Proposition 65

Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, was enacted as a ballot initiative in November 1986. The proposition protects the state's drinking water sources from being contaminated with chemicals known to cause cancer, birth defects or other reproductive harm, and requires businesses to inform Californians about exposures to such chemicals.


Proposition 65 requires the state to maintain and update a list of chemicals known to the state to cause cancer or reproductive toxicity.

Sales Tax Rates

Sales tax is collected based on the applicable state and local sales tax regulations and rates pertaining to goods and shipping services. The tax rate applied to your order will be the combined state and local rates of the address where your order is delivered, with any exemptions applied.


Sales Tax Exemption

Once you provide your tax-exempt certificate, it will be submitted to our third-party service provider for processing and validation. This can take from 3-15 business days to complete. Your certificate will be kept on file and applied to your orders until it expires. Please note that sales tax is based on the address to which the order is shipped. If you give us a certificate for one state, but then ship into another, sales tax will be applied accordingly to your order. If you ship orders into multiple states, certification is required for each one. Please make sure you are logged in to the correct account before purchasing using your exemption.


Shipping Tax to California

For orders shipped to California, we are unable to exempt any part of the shipping cost from tax because California regulations would require us to keep detailed records of the exact cost of transporting an order from our location to the delivery address. Because shipping costs vary on a daily basis, it is essentially impossible for us to update our system to track and report these costs to the penny. The labor and technology costs involved in implementing this change would cause shipping prices to go up significantly. Due to this technology issue and the fact that we add a small handling fee to the order, all shipping into California is correctly being classified as taxable.


Sales and use taxes may still be due on your order
