Class 5.1 oxidizing substances give off oxygen and make other materials burn more fiercely. They are not necessarily flammable themselves, but they must be kept apart from fuels and combustible goods. China exports large volumes of Class 5.1 chemicals, especially water treatment and industrial chemicals, and we handle them by sea and by air where allowed.
Products we commonly ship
- Trichloroisocyanuric acid (TCCA) and calcium hypochlorite for pool and water treatment
- Hydrogen peroxide solutions and sodium percarbonate
- Potassium permanganate, sodium persulfate and ammonium persulfate
- Nitrates such as potassium nitrate and sodium nitrate, and ammonium nitrate based products where accepted
Handling and packaging
- UN-certified plastic drums, fibre drums or bags with secure closures
- Product kept clean and away from organic matter, fuels and other combustibles
- Strict segregation from Class 3, Class 4 and other incompatible goods in the container and at the terminal
- Marine pollutant marking where applicable, for example for many chlorine-based products
Some carriers and ports limit or refuse certain oxidizers such as ammonium nitrate, and quantities per container can be capped. We confirm this before booking. Organic peroxides are a separate class, see Class 5.2 organic peroxides.

FAQ
Can pool chemicals be shipped by air?
Some can, but many oxidizers are forbidden on passenger aircraft and limited on cargo aircraft. Sea freight is usually the practical route for volume. We check the UN number and packing group first.
What documents does a Class 5.1 shipment need?
At minimum a current SDS, the dangerous goods declaration for the mode of transport, and the packaging inspection certificates required for export from China. See goods packaging.
Regulations are revised regularly. IMDG Code Amendment 42-24 is mandatory from 1 January 2026 and the 67th Edition of the IATA Dangerous Goods Regulations applies during 2026. Requirements vary by carrier, port and destination, so please contact us to confirm the rules for your specific shipment.
