USPS Priority Mail International
STANDARDFlat $60 to every international destination, whatever the order size. Some destinations ship by UPS Worldwide Express instead, at the same flat rate. Transit time depends on the destination country and on how long the parcel spends in customs, so we do not quote a delivery window for international orders the way we can for U.S. ones.
Customs & import
PLEASE READYou are the importer of record. Import rules for research compounds differ from country to country, and it is your responsibility to confirm that what you are ordering may lawfully be imported where you live. Customs can inspect, delay, or refuse any international parcel, and we cannot guarantee clearance into any particular country.
- ✓Flat $60 shipping to every international destination — the free-shipping threshold applies to U.S. orders only
- ✓Duties, taxes and customs fees are not included and are payable by you, not by us
- ✓Charged in U.S. dollars — your bank sets the exchange rate and may add a foreign transaction fee
- ✓Tracking emailed when your order ships, the same as a U.S. order
A small number of countries cannot be selected at checkout; where that is the case we are unable to ship there at all. If your order has not moved for an unusually long time, email [email protected] with your order number and we will look into it with the carrier.
Delivery times are estimates provided by the carrier and may vary due to carrier delays, weather, or other factors beyond our control. We are not responsible for delays once the package is in the carrier’s possession. Questions about a shipment? Reach us at [email protected].
