East Harbour Group is an established ammonium perchlorate supplier delivering high-purity AP to industrial, aerospace and defence customers across the UK, Europe and globally. Ammonium Perchlorate (NH₄ClO₄, CAS 7790-98-9) is a powerful inorganic oxidiser, supplied at 99% minimum purity to a controlled commercial specification. It is the primary oxidiser in solid composite rocket propellants – the principal commercial application that has supported space programmes worldwide for decades – and is also used in pyrotechnic compositions, specialised industrial adhesives and certain oxidising formulations. As an ammonium perchlorate supplier in Europe, we deliver AP through compliant multi-modal logistics, with grade variants (including TCP-coated, anti-caking treated commercial grades) available to support specific particle-size and handling requirements.

What is the CAS Number of Ammonium Perchlorate?
The CAS number of Ammonium Perchlorate is 7790-98-9. This unique Chemical Abstracts Service identifier is used to recognise the substance across chemical databases and regulatory systems worldwide. The corresponding EC / EINECS number is 232-235-1, and the Index Number under Regulation (EC) 1272/2008 is 017-009-00-0.
What is the UN Number of Ammonium Perchlorate?
The UN number for Ammonium Perchlorate is UN1442, with the proper shipping name “Ammonium Perchlorate” applied across ADR/RID (road), IMDG (sea) and IATA (air). UN1442 specifically denotes the solid form supplied for industrial use; UN3211 is a separate classification used for perchlorate solutions. Always confirm the correct UN number on shipping documentation against the supplied Safety Data Sheet.
What is the Hazard Class of Ammonium Perchlorate?
Ammonium Perchlorate is assigned Hazard Class 5.1 – Oxidising Substances. It is classified under GHS as Ox.Sol.1 (H271: “May cause fire or explosion; strong oxidiser”), with additional classifications STOT RE 2 (H373) and Eye Irrit. 2 (H319), plus supplemental hazard EUH044 (“Risk of explosion if heated under confinement”). It must be handled in strict accordance with the Safety Data Sheet, kept away from combustible materials, organic substances, metallic powders and ignition sources.
What is the Packing Group of Ammonium Perchlorate?
Ammonium Perchlorate is assigned Packing Group II under ADR, IMDG and IATA – signifying a medium level of transport danger for an oxidising solid. UN1442 / Class 5.1 / Packing Group II is the consistent classification across all transport modes.
Why Partner with East Harbour Group as Your Ammonium Perchlorate Supplier?

- Risk-resilient supply chains: AP supply is materially constrained by the limited number of qualified global producers. Our established global partnerships and supplier diversification reduce your exposure to disruption and provide a more secure, predictable ammonium perchlorate source.
- Specialist Class 5.1 handling: ammonium perchlorate is a strong oxidiser requiring strict separation from combustible materials, organics, metal powders and ignition sources. Our teams handle, store and transport AP in full accordance with international regulations.
- Compliance and traceability: our operations are accredited by UKWA, BIFA and FTA, with full batch traceability and documentation. AP is supplied strictly to legitimate commercial, industrial, aerospace and defence customers, with end-use verification where required.
Ammonium Perchlorate Grades and Specification
Commercial ammonium perchlorate is supplied in a range of grades and particle sizes to suit different industrial applications. East Harbour Group supplies high-purity AP (≥99%) with options including:
- Standard commercial grade: uncoated AP for general industrial oxidising applications and pyrotechnic compositions.
- TCP-coated (anti-caking) grade: AP treated with tricalcium phosphate (TCP) as an anti-caking agent, supporting consistent flow properties and storage stability – commonly specified for solid composite propellant manufacturing where particle handling and predictability are critical.
- Specific particle-size variants: AP supplied to particular particle-size distributions (including 200 micron and other grades) to support burn-rate and performance requirements in propellant formulation.
Specification, particle-size distribution and certification documentation are provided with each batch. Contact our team to discuss your specific application.
Regulatory Classification
Ammonium perchlorate is classified as having endocrine-disrupting properties under EU Regulation (EU) 2017/2100. Perchlorate ion reversibly inhibits iodine uptake by the thyroid gland; ammonium perchlorate does not bioaccumulate and is excreted via the kidneys. Occupational exposure should be managed in line with the Safety Data Sheet, with particular attention to dust control, ventilation and PPE. East Harbour Group supplies AP strictly to legitimate commercial, aerospace, defence and industrial customers with full Risk Management Measures (RMMs) documentation as referenced in the MSDS Annex I.
Core applications of ammonium perchlorate (AP)
The strong oxidising properties and controlled decomposition characteristics of ammonium perchlorate make it indispensable in industries requiring high-energy output under controlled conditions. Principal commercial applications include:
Aerospace & Solid Rocket Propellants
Ammonium perchlorate is the primary oxidiser in solid rocket motors and composite propellants – the principal commercial application that has supported civil and government space programmes worldwide for decades. East Harbour Group supplies AP to aerospace customers and certified propellant manufacturers, with TCP-coated grades available where consistent particle handling and burn-rate predictability are required.
Pyrotechnics
AP is used as an oxidiser in regulated pyrotechnic compositions, including signal flares and certain specialised effects, where controlled energy release and clean burning are required.
Industrial Oxidising Applications
Used in specialised industrial formulations including breakable adhesives (where AP's controlled thermal decomposition supports adhesive break-down at elevated temperatures) and a small number of speciality oxidising applications.
Packaging & Global Delivery
As a hazardous Class 5.1 oxidising substance, ammonium perchlorate requires specialist packaging, labelling and handling throughout the supply chain. East Harbour Group manages the full logistics process for compliant AP delivery worldwide.
Packaging Options
- 25kg bags (smaller volumes and sample orders)
- Drums (recommended packaging per MSDS: metal drums with internal polyethylene coating)
- Intermediate Bulk Containers (IBCs) for larger bulk requirements
Transport Restrictions
AP is regulated for transport under UN1442 / Class 5.1 / Packing Group II. Specific restrictions include:
- ADR (road) and IMDG (sea): limited quantities 1kg, excepted quantities code E2.
- IATA (air): passenger and cargo aircraft maximum 5kg per package; cargo-only aircraft maximum 25kg per package. Air freight requires specialist handling and longer lead times than road or sea.
- All shipments include full transport documentation, marine pollutant assessment (not classified as marine pollutant), tunnel code E and Kemler danger code 50.

FAQs
Under the European GHS / CLP classification used by East Harbour Group, ammonium perchlorate carries the following classifications: Ox.Sol.1 (H271: “May cause fire or explosion; strong oxidiser”), STOT RE 2 (H373: “May cause damage to organs through prolonged or repeated exposure”) and Eye Irrit. 2 (H319: “Causes serious eye irritation”), with supplemental hazard EUH044 (“Risk of explosion if heated under confinement”). AP also has endocrine-disrupting properties classified under Regulation (EU) 2017/2100. Melting point is 150°C, with exothermic decomposition occurring above 270°C. AP must be kept strictly separated from combustible materials, organic substances, metallic powders, sulphur or phosphorus compounds, and all ignition sources. Always handle in accordance with the Safety Data Sheet.
Ammonium perchlorate prices vary substantially by grade, particle-size specification, volume, packaging and destination. Because AP is a regulated Class 5.1 oxidising substance, transport, documentation and handling costs are also material factors in the final delivered price. East Harbour Group provides tailored quotes covering: grade and purity, particle size and any anti-caking treatment (e.g. TCP coating), packaging format, delivery mode (road, sea or specialist air freight), volume tiers and required compliance documentation.
