Fumaric acid (CAS No. 110-17-8) is widely used in food processing, resin production and chemical manufacturing. For importers and downstream manufacturers, choosing a reliable supplier is important for maintaining product quality and ensuring a consistent supply.

Snowhite Chemical supplies food-grade and industrial-grade fumaric acid to customers in different markets. This guide covers product specifications, grade selection, major applications, packaging and shipping considerations to help buyers make informed purchasing decisions.

1. Fumaric Acid: Basic Properties and Specifications

Fumaric acid, also known as trans-butenedioic acid, is a white crystalline powder with low solubility in water and good thermal stability. It is used as an acidulant in food processing and as a raw material in resin and other chemical production.

Typical specifications for exported fumaric acid are listed below. Actual requirements may vary depending on the grade and applicable product standard.

• CAS Number: 110-17-8
• Purity: Typically ≥99.0% for industrial grade and ≥99.5% for food grade
• Appearance: White crystalline powder
• Moisture: Typically ≤0.5%
• Ash Content: Typically ≤0.1%

Heavy metal limits and other impurity requirements should be checked against the relevant product specification and applicable regulations. Buyers should review the technical data sheet (TDS) and certificate of analysis (COA) before placing an order.

For regular bulk purchases, it is also worth checking batch-to-batch consistency, packaging integrity and storage conditions, particularly when the material will be used in food production or resin manufacturing.

2. Food-Grade vs. Industrial-Grade Fumaric Acid

Although both grades contain fumaric acid, they are manufactured and assessed according to different requirements. The right choice depends on the intended application and the customer's quality standards.

Fumaric Acid Food-Grade

Food-grade fumaric acid is used as an acidulant in products such as beverages, baked goods, confectionery and other processed foods. Its acidity and relatively low water solubility make it suitable for applications where controlled acidification is required.

Food-grade purchases should be supported by appropriate quality documentation. Depending on the destination market and application, buyers may need to check compliance with relevant food regulations, as well as Halal, Kosher or food safety management certifications where applicable.

Snowhite Chemical can provide product documentation for customers to review when evaluating food-grade fumaric acid for their markets.

Fumaric Acid Industrial-Grade

Industrial-grade fumaric acid is mainly used in chemical manufacturing, including unsaturated polyester resin production and other industrial synthesis processes.

For these applications, buyers generally focus on purity, impurity levels, reaction performance, batch consistency and overall cost. Industrial-grade material can be a practical choice when food-grade compliance is not required.

Snowhite Chemical supplies industrial-grade fumaric acid for customers with regular consumption requirements, including resin and coating manufacturers.

3. Main Applications of Fumaric Acid

Fumaric acid serves different purposes across the food and chemical industries. Its suitability depends on the formulation, processing conditions and required product performance.

Food and Feed Applications

In food processing, fumaric acid is used to regulate acidity and contribute to the desired taste profile. It can be found in selected beverage formulations, baked goods, confectionery and other processed food products.

Its relatively low water solubility and good thermal stability can be useful in certain formulations, particularly where acidity needs to remain stable during processing.

Fumaric acid is also used in some feed-related applications. Buyers should confirm that the selected grade is suitable for the intended use and complies with local feed regulations.

Resin and Coating Applications

One of the important industrial uses of fumaric acid is in unsaturated polyester resin production. It can be incorporated into resin formulations to achieve specific properties in the finished material.

It is also used in certain chemical synthesis processes and related industrial applications. For resin manufacturers, consistent raw material quality is important because changes in purity and impurities may affect production performance.

When sourcing fumaric acid in bulk, manufacturers should evaluate not only the quoted price but also product consistency, delivery schedules and the supplier's ability to meet ongoing demand.

Pharmaceutical and Fine Chemical Applications

Fumaric acid can also serve as a raw material or intermediate in selected fine chemical and pharmaceutical-related processes. These applications may require tighter specifications and additional quality documentation.

The required grade should be confirmed according to the intended process and applicable regulatory requirements.

4. What to Check When Buying Fumaric Acid in Bulk

For importers, distributors and manufacturers, supplier selection involves more than comparing prices. The following points can help reduce procurement risks.

• Product specifications: Confirm purity, moisture, ash content and any application-specific impurity limits.
• Quality documentation: Request a TDS, safety data sheet (SDS/MSDS) and batch-specific COA.
• Certifications: For food-grade material, check which certifications and compliance documents are available and whether they meet the requirements of the destination market.
• Packaging: Standard options may include 25 kg bags and 1,000 kg bulk bags, subject to availability and order requirements.
• Supply capacity: Discuss monthly consumption, order quantities, lead times and the possibility of repeat shipments.
• Export experience: Confirm that the supplier can provide the necessary shipping documents and coordinate the shipment according to the agreed terms.

For long-term contracts, it is advisable to agree on product specifications, inspection requirements, packaging and delivery schedules before confirming the order.

5. Packaging and Sea Shipment

Fumaric acid is generally shipped as a non-dangerous chemical product, subject to confirmation against the applicable transport classification and shipment requirements.

A common export packaging option is a 25 kg bag with an inner moisture-resistant liner and an outer kraft paper bag. Larger orders may be packed in 500 kg bulk bags, depending on the customer's handling equipment and logistics arrangements.

Because the product is supplied in powder form, moisture protection and secure packaging are important during storage and transportation. Buyers should also consider warehouse conditions, container condition and the expected transit time.

Before shipment, the supplier and buyer should confirm the packaging marks, shipping documents, container loading arrangements and any destination-specific requirements.

Snowhite Chemical can coordinate export packaging and shipping arrangements according to the agreed order specifications.

6. Frequently Asked Questions

Q1: Is fumaric acid the same as maleic acid?

No. Both are isomers of butenedioic acid, but their molecular structures differ. Fumaric acid is the trans-isomer, while maleic acid is the cis-isomer. They have different physical and chemical properties and are not interchangeable in every application.

The appropriate material depends on the requirements of the intended process.

Q2: Can food-grade fumaric acid be used for industrial applications?

In many cases, food-grade fumaric acid may be suitable for industrial applications if it meets the process requirements. However, its higher quality requirements may make it less economical than industrial-grade material.

Before substituting one grade for another, buyers should confirm the technical specifications and suitability for the intended application.

Q3: What is the shelf life of fumaric acid?

Shelf life depends on the product specification, packaging and storage conditions. A period of up to 24 months may apply to certain products, but buyers should follow the shelf-life information provided by the manufacturer.

For best storage results, keep the product sealed in a cool, dry place and protect it from moisture and contamination.

Q4: What documents should I request when importing fumaric acid from China?

Commonly requested documents include the TDS, SDS/MSDS, COA, commercial invoice, packing list and relevant transport documents. Additional certificates may be required depending on the product grade and destination market.

Food-grade buyers should confirm documentation requirements before shipment to avoid delays during customs clearance or product registration.
