Input-output norms require imported printing-ink components to match prescribed formulations and be used in the exported product.

Standard input-output norms prescribe component compositions for Offset Printing Ink Black via the flush route, listing specified inputs such as black base, vehicle gel and plain, polyethylene and PTFE wax compounds, metallic driers and petroleum distillates. The entry is noted as suspended by public notice. Applicants must ensure imported goods correspond to the inputs used or required in the exported product, creating an obligation to determine and observe proportions and to verify that imports are used in manufacture for export.
