Air Transport of Radioactive Materials (Class 7) to Kazakhstan: Rules and Logistics

Specifics of Class 7 Dangerous Goods

Radioactive materials (Class 7) represent the most complex category of dangerous goods (DGR) in international aviation. Unlike flammable liquids or lithium batteries, radioactive substances emit ionizing energy that cannot be seen or felt without specialized instruments. For a procurement specialist or a logistics manager, transporting such materials—whether medical isotopes, industrial flaw detectors from Europe, or calibration sources from the USA—requires flawless compliance with IATA DGR regulations.

KAZLOGIST.KZ organizes the delivery of these specific cargoes, keeping in mind that safety is the top priority. We understand that the slightest error in labeling or the absence of a single permit in Kazakhstan can lead to the cargo being blocked at a transit warehouse, resulting in enormous costs for specialized storage.

Classification and Transport Index (TI)

Before planning a shipment, it is necessary to determine the packaging category. Radioactive cargoes are divided into three main categories depending on the radiation level on the package surface and at a distance of 1 meter from it:

• I-White: minimum radiation level.
• II-Yellow: medium level, requires distance compliance.
• III-Yellow: high radiation level, strict restrictions on placement on board.

A key parameter is the Transport Index (TI). This number indicates the cargo's impact on the environment and determines how many such packages can be placed in a single cargo compartment. KAZLOGIST.KZ specialists check the TI at the booking stage with the airline, as the total index on board is strictly limited by flight safety regulations.

Documentation and Shipper Requirements

A simple invoice is not enough for Class 7 air transport. The primary document is the Shipper's Declaration for Dangerous Goods. It must clearly state: the proper shipping name, UN number, isotope activity in Becquerels, and the physical form of the substance.

In addition, the following are mandatory:

• Material Safety Data Sheet (MSDS/SDS): an up-to-date version in English.
• Packaging Certificate: confirmation that the container has passed tests and complies with IAEA standards.
• Permit Documents: for import into Kazakhstan, a license or permit from the Committee for Atomic and Energy Supervision and Control is often required.

KAZLOGIST.KZ conducts a preliminary audit of documents before the cargo leaves the shipper's warehouse in China, the USA, or Europe. This helps avoid delays during the export customs clearance stage.

Packaging and Labeling: What the Customer Should Watch For

Radioactive cargoes are transported exclusively in certified UN packaging. These can be industrial packages of type A, B, or C, capable of withstanding extreme conditions: from drops to exposure to ultra-high temperatures. KAZLOGIST.KZ draws customers' attention to the fact that packaging must not only be durable but also correctly labeled. Danger signs must be applied to two opposite sides of the package, and the transport index and category must be indicated next to them.

It is important to remember that many radioactive cargoes are allowed for transport only on cargo aircraft (CAO — Cargo Aircraft Only marking). This limits the choice of flights and can affect the logistics chain, as cargo planes fly less frequently than passenger ones.

Logistics Process with KAZLOGIST.KZ

Organizing Class 7 transport through KAZLOGIST.KZ usually includes the following stages:

• Cargo Pick-up: using specialized transport with ADR clearance (in Europe) or appropriate licenses in other countries.
• Booking: coordinating the shipment with the airline and transit airports. Not all airports have a license to handle Class 7.
• Customs Clearance: export declaration in the country of origin and assistance with import procedures in Kazakhstan (Almaty, Astana).
• Door-to-Door Delivery: after arriving at the destination airport and passing customs, the cargo is delivered to the recipient in compliance with radiation safety measures.

Estimated delivery times are: 3–5 days from Europe, 5–8 days from the USA, 3–6 days from China and Asia. The period is counted from the moment the cargo leaves the warehouse until it arrives at the destination airport.

Cost and Weight Calculation

The price of air transport for radioactive cargo is always higher than standard rates. Airlines apply special surcharges for handling dangerous goods (DGR fee) and priority loading. The cost calculation is based on the greater of the actual or volumetric weight. As a reminder, volumetric weight in aviation is calculated using the formula: length × width × height (cm) / 6000. The final price provided by a KAZLOGIST.KZ manager includes the rate per kg, fuel surcharge, security fee, terminal handling, and AWB issuance.
