Heading 3914Ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms

Chapter 39: Plastics and articles thereof

Plain-language overview

Use HS-6 391400 when importing or exporting ion-exchangers made from polymers in primary forms. These products are crucial in water treatment processes, such as softening hard water or purifying drinking water. For instance, a shipment of ion-exchange resin beads used in water filtration systems would fall under this code.

This HS-6 line specifically covers ion-exchangers that are based on polymers classified under headings 3901 to 3913. These materials are often used in various applications, including chemical processing and pharmaceuticals. In contrast, HS-6 391410 covers ion-exchangers in the form of granules or powders, which may have different applications and specifications.

When classifying ion-exchangers, it's essential to note that they differ from other plastic products in this chapter, such as general-purpose plastics or films. Ion-exchangers are specialized materials designed for specific chemical interactions, making their classification distinct within the broader category of plastics.
