Hainan Sea-salt Harvesting and Edible-salt Processing Cluster

Hainan's edible-salt chain is not one plant stretched across the coast. A provincial market-regulator inspection names Yinggehai Salt Works, Dongfang Salt Works and Jinghui Salt as three legal producers. Yinggehai and Dongfang provide solar sea-salt nodes, while Haikou-based Jinghui handles salt processing and smaller packs. Separate notices updated Dongfang's production and wholesale certificates in 2026 and Jinghui's in 2025; Yinggehai filed enterprise standards for old-style and curing salts in 2026. Certificate notices, standards filings and the 2020 inspection each answer different questions and none certifies a current batch or common ownership. Buyers must keep edible and industrial salt apart, verify each producer's production, wholesale and food permissions, then test iodine claims, sodium-chloride content, impurities and lot codes. A 2017 design capacity is not present stock.

Formation and regional foundations

Hainan Routine Inspection of Designated Edible-salt Producers identifies Hainan Sea-salt Harvesting and Edible-salt Processing Cluster, while firm activity still needs a separate check.

Hainan Sea-salt Harvesting and Edible-salt Processing Cluster links controlled seawater brine to solar sea salt. The scale of solar sea-salt harvesting, refining and iodisation, small-pack edible salt and licensed wholesale in Yinggehai in Ledong, Dongfang salt pans and Haikou small-pack processing does not establish any one firm's available inventory.
