Shipping and Returns


Alchemical Research ships by FedEx overnight service with the option of either Next Day Morning or Next Day Afternoon Delivery. Fedex shipments to Alaska and Hawaii are not delivered until 5 PM; there are no 10:30 AM deliveries. We currently do not offer shipping to international destinations through our online store. For further assistance, please contact us at

Orders for in-stock products are typically shipped the same day or the next day after we receive the order, but only if all details including payment and shipping matters are resolved. Alchemical Research is not responsible for delivery delays resulting from events beyond our control including weather, customs, traffic, slow e-mail service, delivery delays within a customer’s institution, or any other type of delay.

During the Christmas and New Year’s holiday period each year, we ship orders every weekday except Christmas Day (December 25) and New Year’s Day (January 1). Orders placed via our online store will be received on those two days but will not be processed until the following business day.

During U.S. Thanksgiving, which is always the fourth Thursday in November, we are closed and do not ship orders on Thanksgiving Thursday or the following day, Friday. Orders placed via our online store will be received on those two days but will not be processed until the following business day.

Other U.S. holidays during the year are single days and typically fall on Mondays, so there is only a 1-day shipping delay, to Tuesday, for orders received on these holidays.


Please inspect all shipments immediately upon arrival. In the event of any damage or discrepancy, please inform us immediately. Conforming goods may not be returned for credit except with our authorization, and then only in strict compliance with our return shipment instructions. Any returned items may be subject to a 20 % processing fee. Under no circumstances will we accept for return any products that are in a non-saleable condition. Non-saleable items include: products with refrigeration or freezing storage instructions; custom products or special orders; opened products supplied in non-resealable containers such as ampules; opened products supplied in tamper-evident capped bottles; and products missing labels or packaging.

Find the order that contains the item(s) to be returned and click on the Return Item(s) button. Fill out the Return Request form and submit. You will be contacted promptly with further instructions.
