Importing radioactive materials and irradiating apparatus into Singapore
Radioactive materials and irradiating apparatus require licensing to import, possess, and use in Singapore. The category is broader than most people assume: it includes X-ray inspection equipment, certain analytical instruments containing sealed sources, and some industrial gauges. Equipment importers frequently discover this when an instrument they thought was ordinary laboratory apparatus turns out to contain a source.
What is typically involved
Requirements depend on the specific product, so treat this as the shape of the process rather than a checklist for your particular case. National Environment Agency (NEA) is the authority on the detail.
- A licence covering import, possession, and use, obtained before the goods arrive.
- Details of the source — isotope, activity, and form — or the apparatus specification.
- A named radiation protection officer or equivalent responsible person, depending on the application.
- Appropriate storage and handling arrangements.
- Transport in accordance with dangerous goods requirements for Class 7.
What catches importers out
These are the recurring surprises in this category — the points where an assumption carried over from another market causes a problem here.
- Analytical instruments — gas chromatographs with ECD detectors, certain gauges — can contain sources without it being obvious.
- X-ray inspection and security screening equipment is in scope as irradiating apparatus.
- The licence is needed before arrival; the equipment cannot wait in a warehouse while it is applied for.
- Disposal and end-of-life obligations also fall under the licensing framework.
- Suppliers do not always volunteer that an instrument contains a source — ask explicitly.
Official sources
Control status depends on the specific product, and requirements change. These are the authorities that decide — confirm your particular goods with them before shipping.

Questions we get asked about this
Does an X-ray machine need a licence?
Irradiating apparatus, including X-ray equipment, generally falls under the licensing framework even though there is no radioactive source in the conventional sense. Confirm the requirement with NEA before importing.
How do I know if my instrument contains a source?
Ask the manufacturer directly and in writing. Several common analytical instruments contain small sealed sources that are not obvious from the product description. This is a question worth asking before purchase, not before shipment.
Can the equipment be held while I apply for a licence?
That is the situation to avoid. Licensing takes time and storage of radioactive material is itself regulated, so an unlicensed arrival is a genuinely difficult position. Apply well before the equipment ships.
More in Do you need an import permit?
E-Waste & Used Electronics
Yes — waste electronics are controlled, and hazardous waste movement is tightly restricted.
Chemicals & Hazardous Substances
Yes for controlled substances — a licence or permit from NEA, plus transport rules on top.
Petroleum Products & Lubricants
Petroleum products are dutiable and controlled; storage brings further licensing.
CITES & Wildlife Products
Yes — CITES permits are required, and the rules apply to finished goods containing listed material.
Toys & Consumer Products
Safety requirements apply, and specific electrical and gas products need registration before sale.
Prohibited Goods
Some goods cannot be imported into Singapore at all, at any quantity, with any permit.
