Shipping Terpenes

You should be aware that shipping research materials, such as terpenes, within the United States and abroad has become a highly regulated process.


The facility requirements for storing terpenes are no different from storing most other common chemicals. Proper care should be exercised and concern should be given to container compatibility, shelf life, and safety.

Shelf Life & Storage Conditions

Under ideal conditions, the shelf life of terpenes is 18 months to two years. Improper storage and handling can lead to reduced shelf life.

Store in a well ventilated area with proper sprinkler/fire deterrent system. Storage temperature should not exceed the flash point (110°F/43°C) for extended periods of time. Keep container closed when not in use. Air should be excluded from partially filled containers by displacing with nitrogen or carbon dioxide. Do not cut, drill, grind, or weld on or near this container; residual vapors may ignite.

The freezing point of terpene formulations vary around -96° C (-142° F). Exposure to extreme low temperatures should not affect the formulation or product quality; however at -78°C (-108°F) d-Limonene will become difficult to pump. It should also be noted that water – which is naturally present in trace amounts – might be extracted from the formulation if exposed to temperatures below 0° C (32° F). Freezing temperatures will not affect the integrity of the product but water may collect at the bottom of the drum or storage tank. If the drum is un-lined, the water may cause rust. This is rarely a storage issue in the phenolic-lined drums used by most companies.


It is recommended that all local storage safety precautions be followed. In many states, terpenes are not considered a hazardous material when stored in a warehouse in drums. When shipped by air or ocean, terpenes are considered a hazardous material and must be labeled accordingly. If terpenes are stored in drums marked with hazardous labels, local regulatory agencies may consider them hazardous. 


International legal landscape for cannabis derived terpenes is questionable at best. Botanically derived terpenes are shipped internationally, that being said some countries have notorious bureaucracy. Both export and import documentation needs to be attached including handling instructions, permissions and safety sheets. It is mandatory to purchase insurance on the package.

Always wear the appropriate personal protective equipment when handling essential oils, especially safety glasses and gloves. The best material for gloves, aprons, and goggles specific to handling terpenes are nitrile , although Viton and polyethylene film will also work.

When transferring from drums or tankers into smaller containers, braided PVC tubing will hold up for a while, but will eventually become rigid. The newer materials using halogenated polymers or fluoromers will work best for this use. Braided PVC or Tygon tubing will hold up for a while.

For clean-up purposes when a NIOSH filter is needed, always use an organic cartridge.

Chemical Companies recommend the use of grounding clamps whenever transferring liquids.

Shipping Regulations

International shipping regulations vary widely from country to country. If appropriate paperwork is not received by the customs official in the destination country, terpenes will not be allowed entrance.
