Beryllia Ceramic Powder
Beryllia (BeO) powder specifically graded for high-temperature ceramic applications like substrates in aerospace components. Falls under HTS 2825.90.1000 as beryllium oxide, distinguished from finished ceramics by its raw powder state per Chapter 28 definitions. Excluded from Chapter 69 as it's not yet a shaped article.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for containing >50% alumina but beryllia-dominant
Refractory ceramics of alumina or silica with metal oxides classify in 6903 if shaped, per chapter note exclusions for finished products.
If as a rare-earth metal compound derivative
Certain beryllium compounds treated as rare-earths in 2846; pure BeO remains in 2825 but complexes may shift.
If doped and formed into electronic wafers
Chapter note specifies doped elements in wafer form go to 3818, not raw oxides in 2825.

Import Tips & Compliance
• Comply with OSHA beryllium standard (29 CFR 1910.1024) for handling; provide material safety data sheets (MSDS) at entry; watch for reclassification if particle size indicates pre-sintered ceramic material
