<h1>SION suspension for pentaerythritol requires verification that imported inputs match export product inputs under trade policy.</h1> Standard Input Output Norms for Pentaerythritol (all grades) set proportions of intermediate chemical inputs and list methanol, formic acid, activated carbon, caustic soda and ethanol per kilogram of product; the SION entry has been suspended by public notice. Determination of input proportions governs allowable imports for export production, and applicants must ensure imported goods are those required or used in the declared export product.
