Dangerous goods (hazardous materials or hazmat) are substances or articles that pose risks to health, safety, property, or the environment during transport. Generally, we offer transportation of dangerous goods by air, sea, inland waterways, and road.
Dangerous goods fall into nine hazard classes, based on the risks they present during transport. These classes cover explosives, gases, flammable liquids, flammable solids, oxidizers, toxic substances, radioactive materials, corrosives, and miscellaneous dangerous goods.
Knowing the correct class helps shippers prepare suitable packaging, labels and transport documents. It also helps freight forwarders and carriers assess whether they can accept the cargo.
Items with a risk of explosion. We do not accept Class 1.
Compressed, liquefied, or dissolved gases. We transport Class 2 with certified packing and appropriate documentation.
Solvents, fuels, and other flammable liquids. Handled under IATA/IMDG rules for air and sea.
Includes spontaneously combustible or water-reactive solids. We ship Class 4 where permitted.
Materials that can cause or intensify fire. Transported with special segregation rules.
Poisons and regulated infectious items. We move Class 6 with strict packaging and labeling.
Radioactive substances. We do not provide Class 7 dangerous goods transporting services.
Acids, alkalis, and other corrosive chemicals. We handle Class 8 with certified containers and labeling.
Hazards not covered elsewhere (e.g., lithium batteries). We ship Class 9 under compliance controls.
A product name or hazard warning alone may not establish its transport classification. Check the following information before arranging a shipment.
UN Number
A four-digit identification number assigned to a dangerous substance or article for transport.
Proper Shipping Name
The official name used to identify the substance or article in dangerous goods transport regulations.
Hazard Class or Division
The primary transport hazard. Some dangerous goods also have subsidiary hazards.
Packing Group
Where assigned, Packing Groups I, II, and III indicate different degrees of danger and help determine packaging requirements.
Safety Data Sheet (SDS)
Section 14 commonly contains transport information for chemical products. Check that it matches the actual goods and intended shipping method.
If the classification is unclear, ask the manufacturer or a qualified dangerous goods specialist to confirm it before shipping.
ASLG can review shipping requests for dangerous goods in Classes 2–6, 8 and 9, subject to the specific UN number, packaging, route and carrier acceptance. We does not accept Class 1 explosives or Class 7 radioactive materials.
A hazard class alone does not determine whether a shipment can be accepted. Restrictions may apply to individual substances, quantities and transport modes.
To request a dangerous goods shipping assessment, prepare:
Depending on the cargo and route, additional declarations, packaging documents or carrier approvals may be required.
A UN number identifies a dangerous substance or article for transport, while a hazard class describes its primary type of danger. Different UN numbers can belong to the same hazard class.
Not by itself. The UN number, quantity, packaging, and applicable transport regulations also affect acceptance. Some goods allowed by sea may face stricter restrictions or prohibitions by air.
Provide product name, UN number and MSDS to start. We’ll handle the rest — packaging, documentation and transport.
