Subheading 400821 of the Combined Nomenclature covers plates, sheets and strip of non-cellular vulcanised soft rubber used as floor coverings and mats. Non-cellular rubber is vulcanised rubber without a porous structure – it has a uniform, compact mass with a density typically in the range of 1.1 to 1.5 g/cm3. Products covered by this subheading include anti-slip rubber mats for industrial halls, workshops and commercial kitchens, electrostatic dissipative (ESD) mats for electronics manufacturing areas, gymnastics and martial arts mats, rubber floor coverings for warehouse platforms and railway station concourses, and animal stall mats for livestock farming. Articles classified under 400821 are finished products intended for use as flooring or a mat – not semi-finished intermediates for further conversion. The base rubber may be natural rubber, SBR, NBR, EPDM, neoprene (CR) or rubber compounds. Recycled rubber products (bonded rubber crumb mats) may be classified under 400821 if they consist of non-cellular vulcanised rubber and have the physical form of a floor covering or mat. The subheading covers both profiled mats (with anti-slip studs, ribs or diamond pattern) and smooth mats, regardless of thickness.

The import of rubber floor coverings and mats (CN 400821) into the EU requires a customs declaration with the appropriate TARIC code and country of origin. The commercial invoice should specify the rubber type, dimensions, thickness, Shore A hardness and any surface treatment or printing. Preferential tariff rates may be available under EU free trade agreements or GSP and require a valid proof of origin. Rubber mats for workplace use are subject to health and safety requirements in EU Member States, including ergonomic assessment under Directive 89/654/EEC (workplace requirements) in some applications. The harmonised standard EN 14041 applies to resilient floor coverings in buildings and may require a Declaration of Performance (DoP) and CE marking where the product is placed on the market as a construction product covered by this standard. Anti-static and ESD mats for electronics manufacturing must comply with EN 61340-5-1. Rubber mats in contact with foodstuffs must comply with Regulation (EC) No 1935/2004 on food contact materials. All rubber articles are subject to REACH (Regulation (EC) No 1907/2006), particularly PAH restrictions under Annex XVII, Entry 50, applicable to articles in contact with skin. The importer should obtain a current REACH compliance declaration and relevant test reports from the supplier prior to the first shipment.

Correct classification under 400821 requires careful distinction from adjacent subheadings. Mats and floor coverings of cellular (foam) rubber fall under subheading 400811 (plates and sheets of cellular rubber) – the absence of a porous structure is the decisive criterion for 400821. Rods, tubes and profiles of non-cellular rubber are classified under subheading 400829, not 400821. Floor coverings and mats made of plastics – PVC, polyethylene, polypropylene or polyurethane – are classified in Chapter 39, not Chapter 40 – the distinction turns on the chemical composition of the base polymer. Rubber floor mats bonded to a jute or other textile backing require analysis of the essential character: if the rubber layer determines the essential character of the product, classification under heading 4008 is appropriate; if the textile backing dominates, classification may fall under Chapter 57 (floor coverings) or Chapter 59 (technical textiles). Articles of hard rubber (ebonite) are classified under heading 4017. Recycled rubber crumb mats must be distinguished from loose rubber crumb (heading 4004) – only bonded, finished mats intended for use as floor coverings are classified under 400821. In doubtful cases, a binding tariff information (BTI) ruling should be obtained from the competent customs authority.
