Import Calcium Formate — Buy in Bulk from Supplier in China

Calcium formate from Rainbow Chemical Industry Ltd. is an industrial-grade feed additive used to improve livestock health and feed efficiency. The product is formulated as a white crystalline powder with a purity of at least 98%, designed for high solubility in water to ensure rapid absorption in animal digestive systems. Its primary function is to act as a dietary calcium source while also serving as a mild acidifier, which helps reduce diarrhea incidence in poultry, cattle, and aquaculture species.

The material is produced to meet typical feed-grade standards, with a calcium content of 30-32% and a formate ion content of 68-70% by weight. It is free from heavy metals such as lead and arsenic, with standard limits below 10 ppm for each. The particle size distribution is consistent, with 90% passing through a 150-micron sieve, making it suitable for uniform mixing in pelleted or mash feeds. Industry practice often pairs it with other mineral supplements to balance electrolyte levels in formulations.

Farmers and feed manufacturers in China and export markets use this additive to enhance growth rates and feed conversion ratios, particularly in monogastric species. It is commonly supplied in 25 kg multi-layer paper bags with polyethylene liners for moisture protection. Buyers should confirm packaging specifications and bulk handling options with Rainbow Chemical Industry Ltd., as the supplier offers flexible terms to accommodate different production scales. The product is used in starter, grower, and finisher diets, with typical inclusion rates ranging from 0.5% to 2% depending on the target animal and dietary requirements.
