About HS Code 391390
This HS code encompasses a broad array of natural and modified natural polymers in primary forms, excluding alginates. This category includes substances like chitosan, dextran, natural rubber (if not covered by specific rubber codes), and various other polysaccharides and biopolymers. These materials are traded globally for their diverse applications in pharmaceuticals, cosmetics, food, textiles, and industrial uses. Major importers are countries with advanced manufacturing and research sectors, such as the USA, Japan, and Germany, seeking specialized functional ingredients. Exporters often come from regions rich in natural resources or with strong biotechnology industries. The trade involves a wide range of products, each with unique properties and applications, requiring careful specification and quality control. The increasing focus on sustainable and bio-based materials is a significant driver for this segment of the polymer market.
Products Under This Code
Chitosan, Dextran, Gellan gum, Xanthan gum, Guar gum (modified), Gum arabic (modified), Pectin (modified)
Real World Examples
Kitozyme Chitosan, Pharmacosmos Dextran, CP Kelco Gellan Gum, Cargill Xanthan Gum, Ingredion Modified Starch
Common Misclassification
This is a broad "other" category for natural polymers and can be easily confused with 391310 (alginates) or even specific cellulose derivatives under 3912 if the natural origin and specific chemical structure are not clearly defined.
Products Classified Under 3913.90
Industry
This code belongs to the Plastics & Rubber industry.
Trade Overview
Top importers include the USA, Japan, and Germany, with exporters originating from resource-rich regions or those with strong biotechnology industries.
