Glucosamine sulfate potassium chloride.
A potassium-chloride-stabilised glucosamine sulfate ingredient for your next supplier qualification.
Manufactured by Shuanglin in China, with a Chinese API manufacturing licence. Request the current licence and confirm its scope and your destination-market requirements.
Request specification & COA ↗Know the salt form.
Glucosamine sulfate potassium chloride is a double salt of glucosamine sulfate and potassium chloride. The names “glucosamine sulfate 2KCl” and “glucosamine sulphate 2KCl” are used in commercial sourcing.
It differs from the sodium chloride form (2NaCl) and from glucosamine hydrochloride. Compare the identity, analytical method and declared assay basis when qualifying a replacement ingredient.

Before you source.
What is glucosamine sulfate potassium chloride?
GSPC is a double salt of glucosamine sulfate and potassium chloride. It is also described commercially as glucosamine sulfate 2KCl or glucosamine sulphate 2KCl. Confirm the precise identity and assay basis against your purchase specification.
Is this a shellfish-derived ingredient?
Yes. Shuanglin’s GSPC is manufactured from shellfish-derived chitin. It should not be described as vegan or shellfish-free. Request the current source and allergen declarations for your assessment.
Does Chinese API licensing authorise use in my country?
Chinese API manufacturing documentation is part of supplier qualification. Overseas acceptance depends on the destination, intended application and the customer’s regulatory assessment. Request the current documents and confirm their scope with your regulatory team.
