Potassium Sulfate
Potassium Sulfate supplied by Huaqiang Chemical Group Stock Co., Ltd. is a colourless crystalline fertilizer identified as K2SO4. The product meets GB/T20406‑2017 standard and contains 50‑52 % potassium oxide with a moisture level not exceeding 1 %. It appears as a light‑yellow granular form that resists caking due to low hygroscopicity. The material is classified under HS code 3104.30 for international trade.
The grade offered is the agricultural SOP grade, which is the chlorine‑free alternative preferred for crops sensitive to chloride. Typical industry specifications call for a chloride content below 1.5 % and a free acid content around 1 %, both of which align with the supplier’s test indices. In the global market SOP is commonly supplied in particle sizes ranging from 0.5 to 2 mm, a range that balances flowability and dissolution rate. Standard bulk density for this material is about 2.1 g cm‑3, matching the supplier’s reported relative density of 2.109.
Major buyers include producers of tobacco, grapes, tea, potatoes and other high‑value horticultural crops that avoid potassium chloride. The product can be used as a base, seed or top‑dressing fertilizer and also serves as a raw material for compound‑fertiliser blends. Trade is typically conducted in bulk bags or bulk shipments, with buyers required to confirm minimum order quantities, incoterms and payment terms directly with the supplier. Shipping considerations include the material’s stability in humid conditions and the need for moisture‑controlled storage.

Sourcing Potassium Sulfate from Huaqiang Chemical Group Stock Co., Ltd. - China Import Guide
Before placing an order, verify the supplier’s laboratory certificate of analysis to confirm key parameters such as K2O content, moisture and chloride levels. Request a recent export batch report to ensure consistency with the specifications listed. Clarify any minimum order quantity, as the supplier’s profile does not disclose this figure, and agree on the preferred incoterm for shipment.
Logistics for bulk potassium sulfate from China typically involve container loading at a nearby port on the Yangtze River. Buyers should confirm the estimated lead time, which can vary with shipping schedules, and negotiate payment terms that align with their risk tolerance, such as a letter of credit. Discuss whether the shipment will be in 25 kg bags or bulk bags, and verify that the packaging meets the destination country’s moisture‑control requirements.
Quality control is essential for fertilizer imports. Arrange for a pre‑shipment inspection by a recognised third‑party lab to verify purity, particle size and moisture content against the supplier’s data. Request the full set of documents, including the certificate of analysis, material safety data sheet and compliance certificates, before the goods leave the factory. Maintaining these records will facilitate customs clearance and protect against non‑conforming shipments.
