Meaning
Official validation of a business entity’s corporate seals by the local Public Security Bureau (PSB) provides the primary means to establish legal authenticity for contracts and administrative filings in China. Through chop registration, a company establishes its unique legal signature, which must be recorded in an official database to prevent fraud. The requirement applies to the official company chop and the financial chop.
It ceases to apply once a business is formally liquidated and its stamps are legally destroyed. Furthermore, foreign-invested enterprises must carry out this process immediately upon receiving their unified social credit identifier to begin banking operations and tax registrations, as banks will not open an account without verifying the registered seals against the PSB records.
Statutory Authority
Regulatory control of corporate seals is managed under public security administration laws to maintain public order and prevent forgery. During chop registration, the enterprise must present its business license and legal representative authorization documents. The local security office carves the seal with a unique serial number and stores the impression.
This registered seal becomes the sole instrument that can bind the enterprise to financial or contractual obligations.
Execution Risk
Contractual validity relies heavily on the physical application of the registered seal rather than a handwritten signature. If a foreign party signs a joint venture agreement with a domestic counterparty that uses an unregistered or incorrect chop, the agreement may be declared void. Many disputes arise when an employee uses an unauthorized stamp or a department-level seal for financial transactions.
Courts resolve these issues by checking the seal impression against the official PSB filing.
Replacement Protocol
Corporate changes or the loss of a physical stamp require a formal cancellation and re-registration procedure. To execute a new chop registration, the enterprise must publish a loss announcement in an approved newspaper before the PSB will authorize a replacement. This measure protects the enterprise from unauthorized concurrent use of multiple seals.
Once the new stamp is registered, the company must update its filings with the tax bureau and its opening bank.
