About natural polymers (e.g. alginic acid) and modified natural polymers (e.g. hardened proteins, chemical derivatives of natural rubber), n.e.c. or included, in primary forms

HS code 3913 covers a diverse range of natural and modified natural polymers that have a wide variety of applications across numerous industries. These materials are essential building blocks for a range of products, from adhesives and coatings to medical devices and pharmaceuticals. The global market for these polymers is expected to grow steadily in the coming years, driven by increasing demand from end-use sectors and the development of innovative new applications.

Production process

The production of natural and modified natural polymers under HS code 3913 typically involves a combination of extraction, purification, and chemical modification processes. Natural polymers like alginic acid are extracted from seaweed or other plant sources, then purified and processed into primary forms. Modified natural polymers, such as hardened proteins or chemical derivatives of natural rubber, are created through controlled chemical reactions that alter the structure and properties of the base materials.

Production inputs

The main inputs required for the production of 3913 polymers include the raw natural materials (e.g., seaweed, plant matter, natural rubber), as well as various chemical reagents, catalysts, and processing equipment. Depending on the specific polymer, the production process may also require specialized machinery for tasks like extrusion, molding, or drying. Energy sources, such as electricity or steam, are also essential for powering the manufacturing facilities.

Production outputs

The polymers classified under HS code 3913 are used as key ingredients or components in a wide range of downstream products. These include 3506 Prepared glues and other prepared adhesives, not elsewhere specified or included; products suitable for use as glues or adhesives, put up for retail sale as glues or adhesives, not exceeding a net weight of 1 kg, 3903 Polymers of styrene, in primary forms, 3912 Cellulose and its chemical derivatives, n.e.c., in primary forms, and 3920 Other plates, sheets, film, foil and strip, of plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials.
