A contract with a Chinese company should be signed only after the foreign counterparty verifies the registered Chinese entity, the signatory’s authority, the company seal or electronic-signature process, and the final document. A familiar sales contact, English trade name, signature image, or payment request is not enough by itself.
Direct answer
A handwritten signature, company chop, authorized electronic signature, later ratification, and actual performance can each be relevant to whether a Chinese company is bound. No single form cures the wrong entity, forged authority, altered terms, or a disputed document. The safest transaction combines entity verification, written authority, controlled execution, version integrity, and consistent performance evidence.
Verify the contracting entity first
Use the registered Chinese name and unified social credit code shown on the current business license and official registry. Compare that entity with the quotation, invoice, bank beneficiary, exporter, factory, online account, and company seal. A translated trade name or related company should not silently replace the legal counterparty.
Check signing authority and internal approval
Request a power of attorney or other written authorization when the signatory is not the registered legal representative. Define authority for the main contract, purchase orders, price changes, guarantees, settlements, bank-account changes, and termination. The PRC Company Law revised December 29, 2023 and effective July 1, 2024 supplies the current company-governance framework, but internal limits and third-party reliance remain fact-specific.
Company chop controls
Where a physical company seal is used, inspect the impression, placement, entity name, and consistency across pages and attachments. Independently confirm unusual signing arrangements and retain the final sealed original. A seal is strong execution evidence, but it does not automatically validate an illegal transaction, an unauthorized guarantee, a forged seal, or terms added after sealing.
Electronic signatures and data messages
The PRC Electronic Signature Law as amended April 23, 2019 recognizes reliable electronic signatures and data messages within its scope. A reliable process should identify the signer, show exclusive control of signing credentials, and reveal later changes to the signature or document. Keep the signed file, certificate, timestamp, authentication, consent, delivery record, and complete audit trail.
Execution checklist
- Current business license, registered Chinese name, unified social credit code, and registered address.
- Identity and written authority of each signatory, including limits on amendments and settlement.
- Final bilingual document with a clear language clause, document hierarchy, and no blank schedules.
- Controlled company-chop or electronic-signature process, with page and attachment integrity.
- Independent verification of bank-account changes and unusual payment instructions.
- Preserved originals, platform audit logs, delivery proof, invoices, payments, and performance records.
When a signature is disputed
Preserve the original paper or native electronic file and stop circulating edited copies. Build a timeline showing negotiations, authority, execution, delivery, invoicing, payment, production, acceptance, and later admissions. The PRC Civil Code, adopted May 28, 2020 and effective January 1, 2021 provides the general contract and agency framework. The outcome depends on the complete evidence, not a marketing statement that a chop or signature is always conclusive.
