Peroxosulfates (Persulfates)

U.S. imports of peroxosulfates (persulfates) (HS 283340) totaled $1.5M in April 2026, traded with 9 countries.

Last updated: April 2026 data

Persulfates — including sodium (2833402000), potassium (2833406010), and ammonium (2833406020) variants — are strong oxidizing agents used extensively in printed circuit board etching, polymer initiation, hair-bleaching formulations, and soil/groundwater remediation. Germany is the leading US import source, with India and Canada also among the top suppliers. Certain persulfate lines originating from China may be subject to Section 301 tariffs, a factor that has prompted supply-chain diversification among electronics and specialty-chemical buyers. The US schedule breaks out individual cation-specific lines, making precise chemical identification essential for correct entry.

Frequently Asked Questions

Why does the cation type matter for classifying persulfates at the 10-digit level?

The US tariff schedule assigns separate 10-digit lines to sodium, potassium, and ammonium persulfates, with a residual line for others. Each line may carry different duty rates or trade-remedy exposure, so accurate chemical identification — confirmed by the supplier's certificate of analysis — is essential for correct entry filing.

What countries are the leading sources of persulfate imports into the US?

Germany leads US import supply, followed by India and Canada. Taiwan and China also rank among the top sources. Importers sourcing from China should assess Section 301 tariff applicability for the specific line item.
