HS-6 · Subheading
390390
Styrene polymers; in primary forms, n.e.c. in heading no. 3903
Heading 3903 — Polymers of styrene, in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-6 390390 when importing or exporting styrene polymers that don't fit into other specific categories under heading 3903. For example, this code applies to certain types of polystyrene used in packaging materials or construction applications.
This HS-6 line narrows down the broader category of styrene polymers to those that are not classified elsewhere. If you are dealing with a specific formulation of styrene that doesn’t fall under more defined HS-6 codes, this is likely the right choice.
For instance, if you have a shipment of expanded polystyrene foam used for insulation, you would classify it under this code. In contrast, if you were dealing with general-purpose polystyrene, you might look at HS-6 390391 instead, which is more specific.
It's important to distinguish between this code and others in the same heading, as misclassification can lead to customs delays or penalties. Always check the specific properties and intended use of your styrene polymer to ensure accurate classification.
