Input-output norms for phenolic foam specify required component proportions and oblige importers to match imported inputs to export production.

Standard input-output norms set the material composition and quantities for Pheno-therm (Phenolic Foam in bun form) at 1 cubic metre (density 40 kg/m3) with listed constituent weights and an adjustment formula for other densities; the SION entry is suspended by Public Notice No. 03/2024-25. Applicants must determine and use the prescribed input proportions and ensure imported goods correspond to those required for the export product, creating a compliance obligation to match imports to declared manufacturing needs.
