What it does
Activated alumina — high-surface-area Al₂O₃ used as a desiccant in compressed-air systems, as a defluoridation adsorbent in drinking water, and as a Claus-process catalyst support. Distinct product from fused / calcined alumina.
Typical applications
- Compressed-air dryers (heatless and heat-regenerative)
- Fluoride removal from drinking water
- Catalyst support (Claus-process sulphur recovery)
- Hydrogen peroxide stabilisation

Industry-typical published bands. Producer-specific values on the COA issued per shipment.
Handling & packaging
- Hygroscopic · keep sealed
- Shelf life 24 months in original packaging
- Not classified as hazardous for transport
Documents on file per shipment
Per-lot COA with adsorption capacity, crush strength, surface areaSDS in EU CLP formatHS 2818 20 00 classification confirmed by broker (distinct from 2818 10 00 fused alumina, which carries anti-dumping duties)
Serica execution notes
- Customs classification confirmed in writing before shipment — activated alumina (HS 2818 20 00) must never be coded against fused-alumina scope, which currently carries EU anti-dumping duties.
- Crush strength explicitly tested — the value that determines bed lifetime in a compressed-air dryer.
- DDP to gate.
