1. Core Product: Sodium Metabisulfite – A Multi-industry Essential Chemical Raw Material

Sodium metabisulfite is a fundamental chemical raw material widely used across industrial and food sectors, maintaining steady demand as a top imported chemical product in South America:

1. Pharmaceutical & Fine Chemical Industry It serves as a core reducing agent and auxiliary for synthesizing pharmaceutical intermediates such as chloroform, phenylsulfone, benzaldehyde, hydroxyl vanillin and hydroxylamine hydrochloride.
2. Rubber, Printing & Dyeing Textile Industry It acts as a coagulant in rubber manufacturing; in printing and dyeing processes, it functions as a dechlorinating agent after cotton bleaching and a kier-boiling auxiliary, eliminating residual chlorine on fabrics and improving color fixation stability.
3. Leather Manufacturing Industry Special auxiliary for leather tanning. Leather treated with it becomes soft, plump and tough, with outstanding waterproof, fold-resistant and wear-resistant properties, making it highly sought-after by South American tanneries.
4. Photography, Printing & Organic Synthesis It is used as a developer in photography, as well as a reducing and antioxidant auxiliary in printing and various organic synthesis reactions.
5. Food Processing Industry Food-grade sodium metabisulfite complying with regulations is applied as a preservative, bleaching agent and leavening agent in fruit & vegetable processing, baking, wine and beverage production.

2. Market Demand: Stable Import Demand at Callao Port, South America

Callao (CALLAO) in Peru, South America, is a pivotal hub port on the west coast of South America, covering the whole territory of Peru and inland Bolivia. Local printing & dyeing mills, tanneries, pharmaceutical processing plants and food factories have sustained high import demand for sodium metabisulfite. Limited local chemical production capacity makes South America heavily reliant on high-purity sodium metabisulfite imported from China. After customs clearance at Callao Port, goods are rapidly distributed to downstream manufacturers across South America, making this route a key export channel for chemical products from South China.
