Different kinds of angstrometric- up to macrometric-scaled constructions can be synthesized from cellulose due to its hierarchical and multi-level organization. There are many commercial products can be obtained from cellulosic resources. Each cellulosic product may be known by several synonyms. Some of these synonyms may not define accurately such product. Accordingly, synonyms standardization is an urgent task to clear things up. We suggested dividing cellulosic products into seven scale categories based on their dimensional scale of their 3-D configurations, namely angstrometric, angstrometric/macrometric, nanometric, nanometric/macrometric, nanometric/micrometric, micrometric, and macrometric-scaled products. To distinctly differentiate the cellulosic products, they were classified based on their dimensions and aspect ratios and were distributed among the seven scale categories. Standardized synonyms of the commercial cellulosic products were suggested. In addition, an identification card (IC) of the cellulosic products was designed.
