<h1>Input output norms for producing 1 kg polyurethane resin solution 60% solids: composition solvent rules importer obligations</h1> Standard input-output norms specify the composition and permissible import quantities for producing 1 kg of polyurethane resin solution at 60% solids (general purpose and an ultrahigh-performance chemical variant), listing required inputs and their weights (e.g., adipic acid, phthalic/isophthalic acids, glycols, toluene diisocyanate, and solvents). Solvent requirement is given as 0.400 kg; other inputs vary by variant. Adjustments for different resin percentages are allowed pro rata for solid inputs and inversely for solvent content. A substitution via prior public notice is recorded, and importers must ensure imported inputs are those actually used in the export product.
