Meaning
Contractual packaging and testing arrangement governed by Ministry of Commerce regulations under the Foreign Investment Law involves outsourcing semiconductor backend operations to specialized domestic suppliers. Foreign semiconductor designers utilize this legal framework to delegate wafer probing and final assembly while retaining intellectual property rights through processing trade contracts filed with local customs authorities. Jurisdictional oversight requires detailed customs ledger registration for imported silicon wafers and subsequent export monitoring of finished integrated circuits.
Operational boundaries exclude front end wafer fabrication, restricting the authorized scope strictly to post wafer production processes.
Tax Liability
Customs supervision manuals classify OSAT subcontracting as processing trade, exempting imported materials from regular value added tax pending final export confirmation. Local tax bureaus mandate rigorous electronic ledger reconciliation between incoming silicon quantities and outgoing packaged components to prevent unauthorized domestic diversion of duty free goods. Variance between physical inventory and customs declarations triggers supplementary corporate income tax assessments based on presumed domestic sales revenue.
Asset Security
Foreign ownership of specialized test equipment supplied to domestic contractors remains protected under official bailment filings registered with the State Administration for Foreign Exchange. Contractual clauses specifying machinery custody prevent local entities from pledging manufacturing assets as collateral for commercial bank loans. Enforcement limitations arise when local courts prioritize domestic worker wage claims over secured foreign equipment repossession rights during contractor insolvency proceedings.
Regulatory Compliance
Provincial commerce departments require annual environmental impact audits before approving capacity expansions for chemical intensive packaging operations. Noncompliance with hazardous waste disposal mandates under national environmental protection laws results in immediate administrative suspension of export licenses rather than standard monetary fines. Bureaucratic delays in processing license renewals frequently disrupt cross border delivery schedules established in primary supply agreements.
