Plastic panels and mouldings remain classifiable as sheets under Heading 3921 when they lack structural building function.

Imported PS mouldings, wall panels, PVC sheets, PVC accessories, PU panels and WPC panels were classified by applying Rule 1 of the General Rules for Interpretation with Chapter Note 10 and the relevant explanatory notes. Plain PVC sheets in rectangular form, even with printing or embossing, retained the character of plastic plates or sheets under Heading 3921. Profilered wall panels and mouldings with tongue-and-groove edges were also held to remain within Heading 3921 because the interlocking features arose from the extrusion process and did not amount to further working. The goods lacked structural, load-bearing or permanent building integration, so decorative wall use did not make them builders' ware under Heading 3925. Classification under Heading 3921 was accepted, subject to verification of composition and structure.

Issues: Whether the imported PS mouldings, PS wall panels, 3D PVC panels, PVC panels, PVC sheets, PVC accessories, PU wall panels, PU panels, PU corners, PU mouldings and WPC panels are classifiable under Heading 3921 as plates, sheets, film, foil and strip of plastics, or under Heading 3925 as builders' ware of plastics.

Analysis: The decisive inquiry was whether the goods retained the character of plastic sheets/panels covered by Chapter Note 10 of Chapter 39, or whether their profile, interlocking edges and decorative use brought them within Heading 3925. The classification was examined under Rule 1 of the General Rules for the Interpretation of the Import Tariff by reading the competing headings with the relevant chapter notes and explanatory notes. Plain PVC sheets supplied in rectangular form, even with surface printing or embossing, were found to retain the character of plates or sheets. For the profiled wall panels and mouldings, the Authority found that the interlocking tongue-and-groove features were integral to the extrusion process and did not amount to further working of the kind that would take the goods out of Heading 3921. The goods were also found to lack structural function, load-bearing capacity or permanent integration into the building framework, and their use as decorative wall coverings did not make them builders' ware or ornamental architectural features under Heading 3925.

Conclusion: The goods were held classifiable under Heading 3921 of the Customs Tariff, with the applicable subheadings depending on their composition, including polymers of styrene, vinyl chloride and polyurethanes, subject to verification of actual composition and structure.

Final Conclusion: The ruling accepted the applicant's classification claim in substance and rejected the department's classification under Heading 3925.

Ratio Decidendi: Goods that retain the essential character of plastic plates or sheets, and are not further worked into structural building articles, remain classifiable under Heading 3921 rather than the residual builders' ware heading under Heading 3925.
