Import Aluminum Potassium Sulfate — Buy in Bulk from Supplier in China

Aluminum potassium sulfate, commonly designated potash alum or potassium aluminium sulphate dodecahydrate, is a white crystalline solid with the formula KAl(SO4)2·12H2O and molecular weight 474.39 g/mol. Lianyungang Huaihua International Trade Co., Ltd. offers this compound for industrial applications spanning water treatment coagulation, textile mordanting, and food-grade firming agent roles. The dodecahydrate form is the standard commercial grade, characterised by high water solubility and strong astringent properties derived from the trivalent aluminium cation's hydrolysis behaviour in aqueous solution.

In water treatment, the aluminium species hydrolyses to form positively charged polynuclear complexes that neutralise and bridge negatively charged colloidal particles, achieving turbidity reduction at typical dosages of 2-15 mg/L as Al depending on raw water quality. The textile application relies on the same metal-complexing behaviour to fix anionic dye molecules to cellulose and protein fibres, improving wash fastness and colour yield. Food-grade material must meet purity specifications limiting heavy metals, particularly arsenic, lead and selenium, with the FAO/WHO Joint Expert Committee specifying maximum levels for aluminium from all sources in food additives.

Industrial buyers include municipal water utilities, textile dye houses, leather tanneries, and food processors requiring firming agents for pickled vegetables or baking powder acidulant systems. The compound ships from Lianyungang port on China's eastern seaboard, with the supplier's location in Jiangsu province placing it within China's dense chemical manufacturing corridor. Packaging, MOQ, exact purity certificates and lead time are not specified in the source data and require direct confirmation with Lianyungang Huaihua International Trade Co., Ltd.

Lianyungang Huaihua International Trade Co., Ltd. is based in Lianyungang, a major port city in northern Jiangsu province on China's Yellow Sea coast. The supplier holds an imported tier and harbor trust classification within the marketplace, with no historical response data currently visible. This profile structure suggests the company operates primarily as a trading entity connecting Jiangsu and Shandong chemical manufacturers with overseas buyers, rather than necessarily operating its own production facility. The exact scope of its in-house technical capability versus pure trading should be clarified before technical specification negotiations.

No factory audit information, ISO certificate numbers, registered capital, employee count, or export volume data appears in the source material. Buyers should request the company's business licence, any REACH pre-registration or full registration status for EU import, and previous bill of lading references to confirm active trade flow. The mention of FSSAI certification in the source text refers to Indian food safety authority certification, which would only be relevant if the supplier has specifically registered its alum product for Indian food additive import, a point worth verifying if that market is the intended destination.
