DISCLAIMER:
For external use only. Our products are intended for use as cosmetic raw materials and should be handled by trained professionals following standard safety protocols.

We strongly recommend consulting a qualified formulator or health practitioner for specific applications.
As of August 29, 2025, there is a 35% tariff or duty charge imposed on all goods coming into the U.S. from Canada. The United States mandates that all packages entering the U.S. from Canada must have their duties prepaid (settled upfront).
Our "USA only" pricing incorporates the necessary duty and processing fee calculated separately for each item. The advantage is that we charge the exact duty for each item and use the most economical shipping rates for orders bound for the U.S. Consequently, our prices are more budget-friendly compared to the Delivered Duty Paid (DDP) shipping option, where you might pay a lower item price but face exorbitant shipping costs, as the estimation for duty and duty processing fees is included in the shipping charges. In the DDP scenario, shipping companies rely on a general estimate for duties which can exceed the true amount, as they do not possess the exact information for each unique item.
