Letter to International Customers concerning Cesium 137 (Cs137) Sources

International orders shipped by Freight Forwarder must only be shipped to customer's or broker's country of destination airport.

Due to stricter security, International shipping regulations for radioactive sources have changed. It is becoming more difficult to deliver door to door. Most countries will no longer allow transportations of radioactive material by common carriers from the airport to a street address.

Source orders to Spectrum Techniques must be assigned and picked up at the airport by you or your representative. To meet these new requirements, orders containing radioactive material (UN2910 Radioactive material, excepted package - limited quantity of material) will only be shipped airport to airport. We will ship Hold At Airport to either you or to your broker’s attention. The goods must be picked up in a reasonable time; otherwise, you will be responsible for the cost of packages returned to Spectrum Techniques. All fees at the airport will be the customer's responsibility; this includes storage, duties, and other fees associated with the package entering country of destination.

When placing your source orders with us, please supply the following information for the representative that will pick up the package(s) at the airport.

(1) Company name

(2) Contact name and

(3) Contact phone number

(4) Any other relevant information
