CAS 1302-42-7

U.S. production volumes are classified as confidential business information.

Molecular structure of 1302-42-7 — 1 Na⁺

US productionCBI

Confidential Business Information. The EPA withholds this volume because publishing it could reveal the reporting company's trade secrets.

Import value, 2024$73M

Top sourceSouth Korea 47%

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. Import value and source-country shares describe a shared customs category, not a separate chemical measurement.

Where It Comes From

Customs basis: HS 284190 · basket

EPA reports by year

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

These shares come from HS customs code 284190, which covers 57 tracked chemicals in total. They estimate the category's origin mix, not this chemical specifically.
