HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Application

Cucurbit[8]uril serves as a macrocyclic host for the selective encapsulation of linear aliphatic and aromatic guests, enabling supramolecular assembly through hydrophobic and ion-dipole interactions. Its large cavity facilitates stabilization of extended molecular frameworks, enhances solubility of hydrophobic compounds, and supports controlled release applications in drug delivery and catalysis. The compound exhibits robust aqueous stability and functions effectively in biologically relevant conditions.
