20xyz
20xyz is a designation used in the International Goods Identification System (IGIS) to classify a specific range of high‑density composite materials. The code is part of the IGIS 2.0 revision, introduced in 2013, and it appears in product catalogs and customs documentation for items that meet stringent durability and environmental compliance criteria. The first two digits represent the weight class (20 kg), while the alphabetic segment “xyz” denotes the material composition: x stands for a carbon‑reinforced polymer matrix, y indicates the presence of a biodegradable filler, and z specifies a flame‑retardant additive.
Manufacturers that supply 20xyz products include several European and Asian firms, such as SparkComposites GmbH and
Academic research into 20xyz focuses on optimizing the ratio of polymer to filler to improve impact resistance
