Top sourceBrazil 99%

At least one company claimed its 2023 production or import volume for this chemical as confidential, so EPA withholds it.

Why supply is unknown

Production is reported production, not a complete census of factories. US production volume is confidential. Production reporting year: 2023.

Where It Comes From

Customs basis: HS 291020 · narrow

EPA reports by year

2023: US production Confidential · Imports Confidential
2019: US production Confidential · Imports Confidential

HS 291020 covers only (+/-)-1,2-Propylene oxide, so these shares are (+/-)-1,2-Propylene oxide's own.
