The Types segment classifies Rochelle Salt into three main grades, each with sub‑categories that affect pricing and end‑use suitability. Pharmaceutical‑grade material, produced under strict purity protocols, includes subtypes such as anhydrous and monohydrate, targeting medical formulations and regulatory‑compliant supplies. Industrial‑grade salt is broader in specification, with subtypes like standard and doped (e.g., lithium‑doped) designed for bulk acoustic resonators and sensor housings. High‑purity analytical grade represents the most refined class, featuring subtypes ultra‑high purity and spectroscopic‑grade, essential for research laboratories and precision optics. Each type’s contribution to market size aligns with its application footprint: pharmaceutical‑grade accounts for roughly 25 % of sales, industrial‑grade 55 %, and high‑purity analytical 20 %, collectively shaping the market taxonomy for Rochelle Salt.
