Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
390320
Styrene polymers; styrene-acrylonitrile (SAN) copolymers, in primary forms
Heading 3903 — Polymers of styrene, in primary forms
Chapter 39: Plastics and articles thereof
Plain-language overview
Use HS-6 390320 when importing or exporting styrene-acrylonitrile (SAN) copolymers in their primary forms. These materials are commonly used in the production of durable plastics, such as in automotive parts or household goods.
This code specifically covers SAN copolymers, which are known for their strength and heat resistance. In contrast, HS-6 390310 applies to pure styrene polymers, which may not have the same properties or applications as SAN.
When dealing with HS-6 390320, you’re looking at products that often come in pellet form, ready for molding or extrusion processes. This distinguishes them from other polymers that might be classified under different headings.
Be aware that other related codes exist, such as HS-6 390330, which covers other styrene copolymers. Understanding these distinctions is crucial for accurate classification and compliance.
