Product Overview

The critical first step in producing high-quality leather is the proper preservation of the raw hide or skin. From the moment of flaying, hides are susceptible to bacterial decay (putrefaction), which can irreversibly damage the grain and reduce the value of the final product. Rudraksh Salt manufactures a specialized Hide Curing Salt designed to rapidly halt this degradation.

Our Sodium Chloride is specifically processed for the tannery industry. It works through osmosis, rapidly dehydrating the hide, removing the excess moisture that bacteria need to thrive. By creating a protective, saline environment, our curing salt ensures that your valuable raw material is perfectly preserved during transport and storage, arriving at the beamhouse in optimal condition for tanning.

Why Our Curing Salt is Trusted by Tanneries

High Purity for Effective Curing

Our salt boasts a high NaCl content with minimal impurities. This ensures maximum water absorption from the hide and prevents unwanted chemical reactions or staining that can be caused by minerals like iron and copper found in lower-grade salts.

Optimal Crystal Size

We offer a range of crystal sizes, from fine to coarse (oversized). Larger crystals are ideal for dry salt packs as they prevent caking and allow brine to drain freely, while finer grades dissolve quickly for efficient brine curing. We can provide the perfect gradation for your process.

Low Insoluble Content

Our salt is clean and free from dirt, sand, and other insoluble matter. This is crucial for preventing foreign particles from becoming embedded in the flesh or grain of the hide, which can cause defects in the finished leather.

Proven Methods for Effective Hide Preservation

Our Hide Curing Salt is perfectly suited for the two primary methods of preservation used in the leather industry


This traditional method involves laying the fleshed hide flat and covering it with a thick layer of our coarse-grade salt. The large crystals resist caking, provide excellent coverage, and allow the resulting brine to drain away efficiently as the hides are stacked. This method provides long-term preservation for storage and shipping.

For rapid, short-term preservation, hides are agitated in a saturated salt solution (brine). Our finer-grade, fast-dissolving salt is ideal for creating these solutions quickly and ensuring a consistent saline concentration. This method is common for processing large quantities of hides in a short timeframe.
