HS-4 · Heading
3914 — Ion-exchangers; based on polymers of heading no. 3901 to 3913, in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-4 3914 when importing ion-exchangers made from polymers listed in headings 3901 to 3913. For example, if you're bringing in a shipment of ion-exchange resins used in water purification systems, this is the correct classification.
When deciding between HS-6 391400 and other potential codes, consider the specific polymer type. If the product is a resin specifically designed for ion-exchange applications, it falls under this heading. However, if it’s a different polymer product, you may need to explore other headings.
The distinction between HS-4 3914 and other nearby headings often hinges on the end-use. If your product is not primarily an ion-exchanger but a polymer used in other applications, you should check the specific characteristics and intended use to classify it correctly.
