Input-output norms suspension for cast iron weights requires importers to verify inputs are actually used in exported products.

Standard Input-Output Norms for Cast Iron Weights classify the product in Engineering Products and note the SION entry has been suspended. Pig Iron is identified as an input. Applicants must determine proportions of inputs used in manufacture and ensure that imported goods are those used or required in the export product, creating a verification obligation for importers under the Input Output Norms.
