Monoethanolamine (MEA), also known as 2-Aminoethanol or Ethanolamine, is an important organic chemical with CAS No. 141-43-5. It combines the chemical properties of an amine and an alcohol, making it a versatile raw material for a wide range of industrial applications.

MEA is widely used in gas sweetening, detergents and cleaners, personal care products, textile finishing, metalworking, pharmaceuticals, agricultural chemicals and other chemical manufacturing processes. It is also used to remove acidic gases such as CO₂ and H₂S from natural gas and refinery gas streams.

For international B2B buyers, however, purchasing MEA is not simply about comparing prices. Storage conditions, temperature management, packaging, product purity and transportation arrangements can all affect the efficiency and reliability of the supply chain.

Why Storage Conditions Matter for Monoethanolamine

Monoethanolamine is a colorless, viscous and hygroscopic liquid. It is also classified as a corrosive substance for transportation purposes, so appropriate storage and handling procedures are important throughout the supply chain.

One point that deserves particular attention is temperature.

MEA has a melting point of approximately 10°C. When temperatures approach or fall below this range, the product may become more viscous or solidify, which can make pumping, unloading and handling more difficult.

For buyers importing MEA during colder seasons, it is therefore important to consider the climate at the destination, transportation conditions and unloading arrangements before placing an order.

Key Storage Considerations for B2B Buyers

1. Keep Containers Tightly Closed

MEA is hygroscopic, meaning it can absorb moisture from the surrounding environment. Containers should therefore remain properly sealed during storage to help maintain product quality.

2. Choose a Suitable Storage Area

MEA should be stored in a dry, well-ventilated area and kept away from strong acids and strong oxidizing agents. The ILO/WHO International Chemical Safety Card also recommends keeping it away from food and feed and storing it in an area without access to drains or sewers.

3. Pay Attention to Temperature During Cold-Weather Transportation

Because MEA has a melting point close to 10°C, buyers in colder regions should evaluate transportation and storage temperatures in advance.

For bulk shipments, the supplier and buyer should communicate about the destination climate, unloading equipment and storage arrangements before shipment. Proper planning can help reduce delays during unloading and subsequent use.

4. Confirm Packaging and Transportation Requirements

MEA is commonly supplied as a liquid chemical and may be transported in drums, IBCs or bulk containers depending on order volume and logistics requirements.

For international shipments, buyers should confirm packaging compatibility, labeling, shipping documentation and applicable dangerous-goods transportation requirements with the supplier before shipment.

Why Purity Matters in Industrial MEA Procurement

For industrial applications, product consistency is an important purchasing consideration.

The required MEA specification can vary depending on the customer’s process. For applications such as gas treatment, chemical synthesis, detergents and other industrial formulations, buyers should confirm the required purity and impurity limits before purchasing.

Our available Monoethanolamine specification:

• Purity: 99.5% min
• CAS No.: 141-43-5
• Chemical Name: Monoethanolamine / 2-Aminoethanol
• Physical Form: Liquid

A clear specification allows buyers to compare products more accurately and helps suppliers prepare suitable quotations and documentation.

Monoethanolamine Supply Outlook

MEA has a diversified industrial application base rather than relying on a single downstream sector. Major applications include gas treatment, detergents, cleaners, personal care, metalworking, textile processing and chemical intermediates.

For international chemical buyers, this makes supply reliability particularly important. A suitable supplier should be able to provide consistent quality while also supporting packaging, documentation and export logistics.

In B2B procurement, the lowest unit price is not always the lowest total purchasing cost. Stable quality, appropriate packaging, reliable delivery and professional export support can all contribute to a more predictable supply chain.
