Shipping Dangerous Goods from Pakistan: IMDG, IATA & Compliance Guide

Pakistan's chemical, pharmaceutical, paint, and battery-related industries ship significant volumes of dangerous goods (DG). Moving them internationally means complying with the IMDG Code for sea freight, the IATA Dangerous Goods Regulations for air, carrier-specific rules, and Pakistan's own export controls. Get it wrong and the result ranges from a rejected booking to a fine or a safety incident. This guide covers the essentials.

DG Classification Basics

Dangerous goods are grouped into nine UN hazard classes:

1. Explosives
2. Gases
3. Flammable liquids
4. Flammable solids
5. Oxidising substances and organic peroxides
6. Toxic and infectious substances
7. Radioactive material
8. Corrosives
9. Miscellaneous dangerous goods, including lithium batteries

Each product is identified by a UN number and proper shipping name, which determine packaging, labelling, stowage, and segregation. Classification is the shipper's responsibility and should come from the safety data sheet and trained personnel, not guesswork.

Documentation Requirements

DG shipments typically need:

• Dangerous goods declaration: the multimodal DG form for sea freight, or the Shipper's Declaration for Dangerous Goods for air, signed by trained staff
• Safety data sheet (SDS): current, in English, and consistent with the declaration
• UN-specification packaging: marked packaging tested for the product's packing group
• Labels and marks: hazard labels and UN numbers on every package
• Container packing certificate: for sea freight, confirming the container was packed and placarded correctly
• Test summaries for lithium batteries: such as the UN38.3 test summary

Carriers check DG documents before they accept a booking. Incomplete or inconsistent paperwork is the most common reason for cancellations.

Ocean vs Air for DG

Some classes, especially explosives and radioactive material, need special permissions and a limited set of carriers and terminals. Others, such as certain flammable liquids, may face terminal restrictions on storage time.

Pakistan Export Considerations

Certain chemicals and controlled substances need permits or NOCs from the relevant Pakistani authorities before export, and some destinations require import permits too. Build these into the order timeline — a DG booking cannot be confirmed until the paperwork is in place.

Booking Lead Times

DG approval adds time. The carrier reviews the declaration, checks segregation against other cargo on the vessel, and may limit how many DG containers it accepts per sailing. In peak months, DG space can fill before general cargo space does.

1. Send the SDS and UN number when you first ask for a quote.
2. Confirm packaging and labels with your packer before production ends.
3. Submit the DG declaration as soon as the booking is requested.
4. Wait for written carrier DG approval before trucking the cargo.
5. Gate in only after approval, within the terminal's DG acceptance window.

Worked example — the wrong packing group: A Karachi paint exporter declared a product in a packing group that did not match the updated SDS. The carrier rejected the DG declaration two days before cut-off, and the cargo missed the vessel while the documents were corrected and the cartons re-labelled.

Worked example — batteries in electronics: An exporter of devices with built-in lithium batteries assumed they were "not DG" because the batteries were inside the equipment. The airline required the correct section of the packing instructions and battery test summaries; without them the shipment was offloaded.

Why Specialist Handling Matters

Some forwarders decline DG cargo or pass it on without oversight. Look for a partner who reviews the SDS before quoting, knows which carriers accept your class on your lane, and checks declarations before submission. MTX coordinates DG bookings by sea and air from Pakistan — carrier acceptance, declaration review, and packing and labelling checks — subject to each carrier's approval for the class and lane. Share the SDS with your enquiry and we will tell you what is possible.
