Top 30 Ammonium Persulfate Suppliers in USA (2026)

Top 30 Ammonium Persulfate Manufacturers & Suppliers Serving the USA in 2026

Last updated: September 29, 2026

Finding 30 companies that physically manufacture ammonium persulfate in the United States is not realistic. According to Evonik, it is currently the only persulfates producer in North America.

This guide therefore compares 30 companies that either manufacture ammonium persulfate globally or supply it to buyers in the United States. The list includes industrial producers, bulk chemical distributors, high-purity material suppliers, and laboratory reagent companies.

The companies are numbered for convenient comparison. The order should not be interpreted as an independently audited market-share ranking. Buyers should verify current production status, inventory, origin, specifications, regulatory documentation, and U.S. delivery capability before placing an order.

Ammonium Persulfate Quick Facts

Ammonium persulfate is a strong oxidizer. Product specifications, handling procedures and storage conditions must always be checked against the supplier’s current Safety Data Sheet.

Quick Answer: Are There Really 30 Ammonium Persulfate Manufacturers in the USA?

No. Publicly available information does not support the claim that there are 30 independent ammonium persulfate manufacturing plants in the United States.

Evonik identifies itself as the only persulfates producer in North America. Most other companies serving U.S. buyers are distributors, importers, specialty chemical suppliers, repackagers or laboratory reagent companies.

For this reason, a reliable sourcing list should distinguish among four business models:

1. North American manufacturers

2. Overseas manufacturers exporting to the United States

3. U.S.-based industrial distributors

4. Laboratory and research-grade suppliers

This distinction matters because each business model offers different advantages in lead time, order size, technical support, traceability and landed cost.

How We Selected These Companies

The following factors were considered when preparing this 2026 supplier guide:

• A public ammonium persulfate product page or documented APS portfolio

• Clear manufacturer, distributor or laboratory-supplier status

• Ability to serve industrial, commercial or research buyers

• Availability of specifications, SDS, COA or other technical documentation

• Grade and packaging options

• Application coverage

• U.S. presence or potential export availability

• Public information available as of September 29, 2026

Availability can change. Overseas manufacturers should not automatically be assumed to have local U.S. inventory.

How to Select an APS Supplier by Application

Polymerization and Synthetic Latex

For emulsion polymerization, buyers should evaluate:

• Assay and active oxygen

• Iron and manganese limits

• Reaction consistency

• Moisture

• Insoluble matter

• Batch-to-batch performance

• Storage stability

A low purchase price does not compensate for inconsistent initiation rates or polymer quality.

PCB Etching and Electronics

Electronics applications may require tighter controls on:

• Iron

• Heavy metals

• Chloride and chlorate

• Insoluble matter

• Particle contamination

• Lot traceability

Do not assume that a general 98.5% industrial product is automatically suitable for electronics. Request an impurity profile that matches the process.

Oilfield Gel Breaking

Oilfield purchasers should define:

• Required break time

• Operating temperature

• Particle size

• Standard, coarse-particle or encapsulated form

• Compatibility with the fracturing-fluid system

• Moisture resistance

• Field-test requirements

The correct particle form may be more important than a small difference in assay.

Hair Bleaching and Personal Care

Buyers should request a grade specifically supported for the intended formulation. Review applicable cosmetic regulations, impurity limits, dust control, sensitization information and supplier documentation.

Industrial-grade material should not be substituted without technical and regulatory review.

Soil and Groundwater Remediation

Persulfate performance depends on activation method, contaminant type, soil chemistry, dose and delivery design. Supplier selection should therefore include technical discussions about the remediation system rather than focusing only on APS purity.

Laboratory Electrophoresis

For electrophoresis, use molecular-biology or electrophoresis-grade APS. Depending on the protocol, buyers may require:

• High purity

• DNase- and RNase-free status

• Protease-free status

• Small package size

• Lot-specific COA

• Reliable storage history

APS Specification and COA Checklist

Before approving a supplier, request a recent COA and compare the following items:

The specification should match the end use. A COA showing only “purity” is not sufficient for many industrial applications.

U.S. Transportation, Import and Compliance Considerations

Hazardous-Materials Classification

Ammonium persulfate is transported as:

• UN number: UN 1444

• Proper shipping name: Ammonium Persulfate

• Hazard class: 5.1

• Packing group: III

Confirm that the packaging, labels, carrier and shipping documents comply with applicable U.S. Department of Transportation requirements.

Safety Documentation

Request a current U.S.-format SDS before purchase. The SDS should identify the manufacturer or responsible supplier, hazard classification, emergency contact, handling requirements and transport information.

TSCA and Intended Use

U.S. importers should obtain written confirmation regarding applicable TSCA inventory and intended-use requirements. The importer of record remains responsible for import compliance.

Chinese-Origin Persulfates

The United States maintains an antidumping order covering persulfates from China. Buyers considering Chinese-origin APS should confirm:

• Whether the product falls within the order’s scope

• Current cash-deposit rate

• Manufacturer and exporter identity

• Country of origin

• Applicable Section 301 or other duties

• Customs-broker and importer-of-record responsibilities

Quoted FOB or CIF prices should not be compared with domestic prices until duties, hazardous-material freight, customs fees, insurance and inland delivery have been added.

Storage

Store ammonium persulfate in accordance with the latest supplier SDS. General precautions include keeping it:

• Cool and dry

• In a well-ventilated area

• In tightly closed compatible packaging

• Away from heat

• Away from combustible and organic materials

• Away from reducing agents and incompatible chemicals

• Protected from contamination and moisture

Frequently Asked Questions

Who manufactures ammonium persulfate in the United States?

Evonik states that it is the only persulfates producer in North America. Other U.S. companies in this guide are primarily distributors, specialty suppliers, repackagers or laboratory reagent companies.

What is the CAS number for ammonium persulfate?

The CAS number is 7727-54-0.

What is the difference between a manufacturer and a distributor?

A manufacturer produces APS at a chemical plant. A distributor purchases material from a manufacturer and provides services such as local inventory, smaller quantities, credit terms, repackaging, logistics and technical support.

Always ask a distributor to identify the original manufacturer and country of origin when traceability is important.

What is the typical purity of industrial ammonium persulfate?

Common industrial specifications are approximately 98% to 98.5% minimum. However, suitability depends on active oxygen and impurity limits, not purity alone.

Is ACS-grade APS better than industrial-grade APS?

Not in every application. ACS grade is useful for analytical and laboratory work, while an application-specific industrial grade may be more economical and better suited to polymerization, PCB processing or oilfield use.

What documents should an APS supplier provide?

At minimum, request:

• Lot-specific COA

• Current SDS

• Product specification or TDS

• Manufacturer and country-of-origin declaration

• Packing information

• Shelf-life statement

• Transport classification

• Applicable regulatory documentation

Can Chinese ammonium persulfate be imported into the USA?

It may be imported subject to applicable laws, but Chinese-origin persulfates are covered by a U.S. antidumping order. Importers should obtain professional customs advice and confirm current duty exposure before purchasing.

What packaging is commonly used?

Industrial APS is commonly supplied in lined 25 kg or approximately 55 lb bags. Drums, pails and larger packaging may be available depending on the supplier and grade. Laboratory products are normally sold in gram or kilogram containers.

What determines ammonium persulfate price?

Major price factors include:

• Grade and impurity limits

• Order quantity

• Packaging

• Country of origin

• Dangerous-goods freight

• Import duties

• Delivery distance

• Inventory availability

• Payment terms

• Required documentation

• Custom particle size or formulation

Which supplier is best?

There is no single best supplier for every application.

• Choose a North American producer or domestic distributor when lead time and local supply are priorities.

• Choose a global industrial manufacturer when volume and factory-direct pricing are priorities.

• Choose a specialty or laboratory supplier when purity, small packaging and documentation are more important than bulk price.

Final Supplier Selection Advice

The U.S. ammonium persulfate market includes one publicly identified North American producer, several domestic distributors and laboratory suppliers, and a group of overseas manufacturers serving international buyers.

Do not select a supplier only because it appears first in a list. Send the same written specification to at least three qualified companies and compare:

• Lot-specific quality

• Manufacturer identity

• Country of origin

• Documentation

• Lead time

• Packaging

• Supply continuity

• Technical support

• Total landed cost

For industrial APS with a published 98.5% minimum specification, export documentation and coarse-particle options, review Aozun Chemical’s ammonium persulfate or contact the Aozun sales team for a current COA, SDS, sample and destination-based quotation.
