Polymers, natural; alginic acid, its salts and esters, in primary forms

HS code 391310 covers the import and export of natural polymers, alginic acid, and its salts and esters in primary forms. These materials are essential components in a wide range of industries, including food, pharmaceuticals, cosmetics, and textiles. The global market for natural polymers and alginic acid is expected to grow steadily in the coming years, driven by increasing demand for sustainable and eco-friendly raw materials.

The primary production technique for natural polymers and alginic acid involves the extraction and purification of these materials from various natural sources, such as seaweed, algae, and certain plants. The extraction process typically involves steps like harvesting, drying, milling, and chemical treatment to isolate the desired compounds in their primary forms.

The main inputs required for the production of natural polymers and alginic acid include the raw materials (e.g., seaweed, algae), processing equipment (e.g., drying machines, milling equipment, chemical reactors), and various chemical reagents used in the extraction and purification processes. Additionally, energy sources, such as electricity or fuel, are needed to power the production facilities.

The primary outputs of HS code 391310 are natural polymers, alginic acid, and its salts and esters in their primary forms. These materials are then consumed by various downstream industries, such as 190110 Food preparations, 300490 Medicaments, 330499 Cosmetic and toilet preparations, and 550410 Artificial filament tow, where they are used as thickeners, stabilizers, gelling agents, and other functional ingredients.
