<h1>Input output norms require declared input compositions for vinyl acetate copolymer emulsion and matching imported goods to export use.</h1> Standard input output norms set specific ingredient compositions for one kilogram of Vinyl Acetate Copolymer Emulsion Stabilized with Colloid (H487), listing two solid content variants (54% 1 and 48% 1) with fixed quantities of Vinyl Acetate Monomer and Hydroxy Ethyl Cellulose; the quantities are specific, not pro rata, and applicants must declare either variant A or B. Schedules determine allowable input proportions and require applicants to ensure imported goods correspond to those actually used in the export product.
