Magnesium silicide (Mg2Si)
CAS 22831-39-6
Used in 4 industrial sectors tracked by the EPA.
Production is reported production, not a complete census of factories. Production reporting year: 2023. Import value and source-country shares describe a shared customs category, not a separate chemical measurement.
Where It Comes From
Customs basis: HS 285000 · basket
- 2023
- US production 368.4K lb · Imports Zero
- 2019
- US production 686.4K lb · Imports Zero
HS customs code 285000 covers 58 tracked chemicals in total. US Census does not break out this chemical's share, so the country-of-origin mix is not available. EPA CDR reports import dependency at the chemical level separately, shown above.
