Acetal Engineering Sheets
Acetal engineering sheets are noncellular sheets made from polyoxymethylene (acetal) resin, used for machining into precision engineering components. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. The acetal polymer meets the 95% purity threshold for the 'poly' prefix, but falls under 'other plastics' as no specific subheading covers acetal sheets.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the sheets are made of poly(methyl methacrylate) (PMMA), not acetal
PMMA sheets have a specific subheading; acetal sheets do not, so they fall under 'other plastics'.
If the sheets are further worked into finished articles, such as machined components
Articles of plastics not elsewhere specified are classified in heading 3926.

Import Tips & Compliance
• Verify that the acetal sheets are noncellular and free from reinforcement or lamination to stay within this tariff item
• Provide technical data sheets showing the polyoxymethylene content to support classification
• Be aware that if the sheets are cut to non-rectangular shapes or further worked, they may be classified elsewhere

ABS Flexible Forming Sheet 0.7mm
This is a flexible, noncellular sheet of acrylonitrile-butadiene-styrene (ABS) copolymer, 0.7 mm thick, cut into sheets for thermoforming prototypes. It is not reinforced, laminated, or supported with other materials, and falls under the tariff item for plates, sheets, film, foil, and strip of other plastics.
ABS Prototype Sheets
ABS prototype sheets are noncellular sheets made from acrylonitrile-butadiene-styrene copolymer, used for rapid prototyping and model making. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. The ABS copolymer predominates over single monomers, meeting the classification rules for polymer blends.
Acrylic Flexible Sheet 0.6mm
This is a flexible, noncellular polymethyl methacrylate (PMMA) sheet, 0.6 mm thick, used in graphic overlays and membrane switches. It is not reinforced or laminated, and is classified as a plate, sheet, film, foil, or strip of other plastics.
Cellulose Acetate Ophthalmic Sheets
Cellulose acetate ophthalmic sheets are noncellular sheets made from cellulose acetate, available in assorted colors, used for eyeglass frame fabrication. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. Cellulose acetate is a cellulose polymer, and the sheets are not covered by a more specific subheading.
Clear PVC Document Sleeves Sheets
Clear PVC document sleeve sheets are noncellular polyvinyl chloride sheets cut to size for document protection sleeves and binders. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. These PVC sheets do not meet the specific subheading requirements for plasticized or unplasticized PVC, so they fall under 'other plastics'.
ETPU Foam Precursor Sheets
ETPU foam precursor sheets are noncellular expanded thermoplastic polyurethane (TPU) sheets used as precursors for subsequent steam-chest molding in athletic footwear manufacturing. They are classified under this tariff item as plates, sheets, film, foil and strip of other plastics, non-cellular and not reinforced, laminated, supported or similarly combined with other materials. These TPU sheets are not yet expanded and are not covered by a more specific subheading.
