Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If unvulcanized primary form
Unvulcanized synthetic rubber in bulk forms stays in 4002; vulcanization moves to 4008.
If cellular polyurethane plastic
Polyurethane classified as plastic (not rubber) goes to 3921; chemical definition controls.
If specifically for floor coverings
Cellular rubber sheets designated for flooring have separate statistical breakout.

Import Tips & Compliance
• Confirm polyurethane qualifies as synthetic rubber via vulcanization/elongation tests in chapter note 2
• Document block dimensions showing regular geometric shape; irregular lumps classify differently
• Prevent reclassification to Chapter 39 by providing rubber polymer composition analysis

Neoprene Foam Sheet
A flexible sheet made from cellular vulcanized neoprene rubber, used for gaskets, seals, and insulation in industrial applications. It falls under HTS 4008.19.80.00 as it is a plate/sheet of cellular rubber, other than hard rubber, not specifically provided for elsewhere. The cellular structure provides compressibility and buoyancy.
EVA Foam Rubber Pad
Ethylene-vinyl acetate (EVA) cellular rubber sheets cut to rectangular pad shapes for flooring, mats, and protective packaging. Classified under 4008.19.80.00 as uncut or simply cut rectangular cellular rubber sheets of vulcanized rubber. Meets chapter notes for plates/sheets as blocks of regular geometric shape.
Silicone Sponge Rubber Strip
Cellular silicone rubber strips in rectangular cross-section for thermal insulation and gasketing in HVAC systems. HTS 4008.19.80.00 covers such vulcanized cellular rubber strips simply cut to length. Excludes textile-covered belting per chapter note.
Nitrile Foam Rubber Sheet
NBR (nitrile butadiene rubber) cellular foam sheets for oil-resistant gaskets and seals in automotive applications. Falls under 4008.19.80.00 as 'other' cellular vulcanized rubber plates not for floor coverings or celling rubber. Rectangular sheets simply surface-worked (e.g., textured).
