Why Choose the 25kg Package

Caustic soda pearls 25kg is the standard small-bag specification of high-purity granular caustic soda, designed for buyers who value flexible stock control, easy material handling and dependable quality. Compared with bulk jumbo bags, the 25kg package lets you manage inventory more precisely, order in smaller quantities and adjust consumption according to actual production needs. It is particularly suitable for medium-scale factories, water treatment stations, soap workshops and distributors who need a convenient, low-risk way to purchase high-quality alkali.

Product Quality

Our caustic soda pearls are produced through advanced ion-exchange membrane electrolysis and concentration processes, with a guaranteed purity of 99% minimum caustic  soda. The product features low chloride, low iron and low heavy metal content, ensuring stable alkalinity and clean reaction performance in sensitive processes. Each batch is sampled and tested in our laboratory, and the results are recorded in the Certificate of Analysis (COA) provided with every shipment.

Physical Features

Unlike flakes or irregular lumps, caustic soda pearls have a smooth spherical shape with uniform particle size. This structure brings several practical benefits for daily production: the round particles flow freely through feeding hoppers and dosing equipment without bridging; the dense surface produces very little dust when the bag is opened and poured; and the product dissolves quickly and completely in water, releasing uniform alkaline strength into the process solution. These features help reduce material loss, improve operator safety and simplify workshop management.

Main Application Fields

The 25kg packed caustic soda pearls are widely accepted in the following industries:

• Municipal and industrial wastewater treatment, for pH adjustment and heavy metal precipitation
• Soap, detergent and surfactant manufacturing, as the key alkali for saponification
• Textile scouring and mercerizing, where low iron content protects fabric color
• Biodiesel production, as the catalyst for transesterification of vegetable oils
• Leather processing, for liming and hair removal in tanneries
• General cleaning and CIP operations, for removing grease and organic residue

Packaging and Protection

Caustic soda is a strongly hygroscopic substance, so moisture protection is critical for keeping the product free-flowing. Each 25kg bag is constructed with a heat-sealed polyethylene (PE) inner liner and a strong woven polypropylene (PP) outer layer. This double-layer structure prevents humidity absorption, caking and quality deterioration during long-distance sea shipment and extended storage. Bags are stacked on standard export pallets and wrapped with stretch film, which keeps the load stable inside the container and simplifies warehouse counting and handling.

Export Documentation and Service

We support every order with a complete set of export documents, including commercial invoice, packing list, COA, MSDS and other certificates required for customs clearance. Our export team has long experience in shipping chemical products to Europe, the Middle East, Southeast Asia, Africa and Latin America, and can arrange suitable containers, pallet specifications and loading plans according to your requirements. For buyers who need brand building, customized bag printing is also available.

Flexible Ordering

Because the 25kg specification comes in moderate units, we are able to accept trial orders as well as full container loads. This flexibility is especially helpful for new customers who want to evaluate product quality first, or for established buyers who need steady but adjustable supply. With factory-direct pricing and stable production capacity, we can guarantee competitive prices and reliable lead times for both small and regular orders.
