Fill Out The Form

For those who want to handle their own shipping...

Below is a step-by-step explanation of how to prepare, pack and ship your gauge to Humboldt, if you choose not to take advantage of our EaZy Shipping. For reference you can also download the Humboldt Transportation Guide, which provides in-depth information for transporting nuclear gauges.



Download the Humboldt RMA form from our website here: RMA Form (download). Fill out the form completely, print it out, and pack it with your gauge for shipping.



First, you will need a current, valid leak test for the gauge you wish to ship, before shipping it. Be sure to correctly indicate a valid leak test is available when you fill out the Humboldt RMA form in the next step. If you don’t have a valid leak test, you can purchase leak test kits from Humboldt, perform the test, and send it to Humboldt for evaluation. You will then be sent a valid leak test certificate, which you can then refer to on your RMA form.

If your gauge is Damaged: If the gauge you wish to ship is damaged and you want to send it to us for repair or disposal, you must call us at 1.800.537.4183 for prior approval. We will require that you send us photos, as well as a leak test, which has been performed on the gauge after the damage was inflicted.

Shipping by Freight Carrier: If you plan to ship your gauge by freight carrier, download the Bill of Lading (BOL) form from our website here: Bill of Lading (download). Fill out the form completely. This form needs to be attached to the outside of the nuclear gauge shipping case during shipment. We use R&L as our shipper and the Bill of Lading download reflects that. This form has our shipping information filled in, you just need to complete the form with your information and use the drop down menus to auto fill-in the shipment information.

To populate the correct HazMat Shipping information for the gauge(s) you are shipping, select the appropriate gauge type from the drop down menu, located in the Description of Articles field.

If you are shipping multiple gauges, use a separate form for each type of gauge. You can ship multiple gauges of the same model on a single form, but different model gauges must be on a separate form. The form will automatically calculate the total weight of multiple gauges.

The form will fill out the Transport Index number based on your gauge type choice.

If there are multiple documents, fill in the page numbers at the top right of the forms.

Print TWO (2) copies of each BOL needed and sign on the “Signature of Consignor” line and next to “Shipper” at the bottom left-hand side of the page.

To schedule a pick up, contact R&L at 1.800.543.5589, or visit their website at: All shipping costs will appear on your final invoice.

Give ONE set of the BOL to the R&L Carrier’s driver, and keep ONE set of the BOL for your records.



Shipping by FEDEX: Completely fill out a Federal Express Waybill and Shipper’s Declaration for Dangerous Goods Form. On the waybill, be sure to check “YES” under the heading “Does the shipment contain dangerous goods?”; and check “Cargo Aircraft Only”. Please note that FedEx requires that all DG Forms be typed. Waybills can be generated online or downloaded from the Fedex website: They can also be acquired from the Fedex driver.

On the forms above, the areas shaded in gray need to be provided by you, the shipper. Please be sure to read the Disclaimer & Instructions prior to using these forms to ensure that all required information is provided correctly.

Emergency Response Phone number and contact name must be included on the Dangerous Goods document as to who to notify in case of emergency during shipment.

Forms are in PDF format. These forms may be used for shipments made via FedEx or any other air carrier that accepts radioactive shipments.

Print 4 copies of the Dangerous Goods Form. Note: A color printer is needed to print these forms properly. The red marks on either side of the form MUST appear in red or the carrier will not accept the form.

Packing Gauges for Shipment: To begin, fully retract the Source Rod into the gauge and lock in the “safe” position by installing a padlock through the hole in the handle trigger. Pack the gauge into its transit case. Include only the gauge and its Reference Standard Block. Do not send tools. Include a copy of your current and complete Radioactive Materials License.

Lock the transit case by installing a zip tie or a Humboldt issued padlock. If you have changed padlocks, aren’t sure if you changed them, or are sending another manufacturer’s gauge, place the keys in an envelope and securely attach them to the outside of the transit case.

A Tamper Evident Security Seal may also be used to seal the shipping case per USDOT regulations. Be aware that damaged cases with holes or cracks other than superficial marks will not be permitted for shipping.

A current and valid leak test for the gauge is required prior to shipping. Be sure to correctly indicate, on the Humboldt RMA form, that a valid leak test is available. Include the RMA form inside the transit case.

Confirm that Yellow II labels, indicating exactly what is in the transit case, are on the front and rear of the transit case, as required by regulations. In addition to the Yellow II labels, orange and black Cargo Aircraft Only (Do Not Load in Passenger Aircraft) labels are required to be attached to the front and rear of the transit case.
