Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If flexible rather than rigid
Flexible PMMA film, foil, or strip classifies under the separate flexible subheading.
If imported as part of complete lighting fixtures
Parts of lamps (e.g., diffusers attached to housings) go to Chapter 94.
If surface-textured or embossed
Worked PMMA sheets with patterns or textures are 'other plates, sheets' in 3921.

Import Tips & Compliance
• Document optical properties and flame test results to distinguish from flexible films in 3920.53
• Ensure import invoices specify 'non-flexible sheets' to match subheading language exactly
• Beware of chemical modification levels; per notes, these go to 'Other' if not pure PMMA
