B2B Quality Control and Evaluation Workflow
Define Target Specifications: Identify required purity, concentration, physical form, and impurity limits.
Review Technical Documents: Evaluate the product TDS, SDS, and representative batch COA.
Sample Testing: Verify assay, pH, and trace impurities in an accredited laboratory.
Dissolution & Physical Inspection: Confirm complete solubility and lack of suspended solids.
Formulation Compatibility: Perform jar testing with calcium, magnesium, phosphate, and micronutrient salts.
Storage Stability Testing: Monitor solution stability under local ambient and cold storage conditions.
Commercial Approval: Confirm lead times, MOQ, packaging options, and batch traceability systems prior to ordering.
FAQ
Q: What are the main agricultural advantages of using Potassium Thiosulfate (KTS)?
A: KTS delivers highly soluble potassium and sulfur without introducing chloride. Its superior water solubility makes it ideal for clear liquid fertilizers and drip irrigation, preventing line blockages while supplying readily available plant nutrients.
Q: Is KTS compatible with all other liquid fertilizer ingredients?
A: While KTS is highly soluble, it can react or form precipitates under acidic conditions or when combined with high concentrations of unchelated calcium, magnesium, or strong acid inputs. Compatibility jar testing is recommended before large-scale blending.
Q: In what physical forms is KTS commercially supplied?
A: KTS is supplied either as a dry, crystalline solid for high-purity applications or as a ready-to-use aqueous solution tailored for liquid fertilizer manufacturing.
Q: What key details should be included in a Request for Quotation (RFQ) for KTS?
A: An RFQ should specify the required physical form (solid or liquid), target concentration or purity assay, impurity limits, packaging preference (e.g., IBC totes, drums, 25 kg bags), order volume, destination port, and required documentation (TDS, COA, SDS).
Q: How is batch consistency maintained for long-term supply agreements?
A: Consistency is guaranteed through strict raw material inspection, automated process controls (pH, temperature, filtration), and lot-specific COA validation. Every shipment is linked to a batch number for complete traceability.
