I. When exporting through an agency company, can the customer query the customs declaration form by themselves?

According to Announcement No. 37 of the General Administration of Customs in 2025, the query rights of the customs declaration form under the agency export mode are divided into three situations:

• Enterprises with electronic entrustment filingCan directly log in to the China International Trade Single Window (https://www.singlewindow.cn), view the complete customs declaration data through the "Enterprise Customs Declaration Query" module.
• Enterprises without electronic entrustmentNeed to provide:
  • The original export agreement signed with the agency company
  • The power of attorney stamped with the official seals of both parties
  • The pre - entry number of the customs declaration form

  Apply to the Comprehensive Business Section of the Customs for querying

• Enterprises in special regulatory areasThe query needs to be carried out through the IC card of the electronic port declared by the agency company (self - query is not supported in some regions temporarily).

II. How to handle it when the amount on the customs declaration form does not match the actual transaction amount?

After the implementation of the new version of the Regulations on Customs Inspection in 2025, it is recommended to handle data differences according to the following steps:

• The first step: Evidence collection
  • Preserve the original proforma invoice and commercial invoice.
  • Obtain the shipping advice issued by the freight forwarder.
  • Check the expense list provided by the agency company (including details of customs declaration service fees).
• The second step: Difference analysis
  • Exchange rate conversion difference (a ±2% fluctuation is allowed).
  • Difference in freight/insurance premium calculation methods (conversion between FOB and CIF quotations).
  • Adjustment of the declared price due to commodity classification.
• The third step: Dispute resolution
  • Submit a written objection to the agency company within 15 working days.
  • Apply for mediation through the China Council for the Promotion of International Trade (CCPIT).
  • If the amount involved exceeds $50,000, an application can be made to the customs for the price challenge procedure.

III. Why cant the customs declaration form for agency export be found in the single window?

According to the customs data statistics in 2025, about 12% of the agency export enterprises have encountered abnormal queries. The main reasons include:

• Data synchronization delay: The cross - border land transportation declaration data may be delayed for up to 72 hours (sea transportation is usually synchronized within 24 hours).
• Difference in declaration mode: Goods declared under the "two-step declaration" process can only be queried after the complete declaration is submitted.
• Permission configuration problem: Some agency companies restrict the query permissions of "operating units".
• Abnormal system connection: Enterprises in the bonded area/comprehensive bonded area need to query through the local electronic port platform.

IV. How to verify whether the agency company makes a true declaration?

It is recommended to use the triple - verification method to ensure the authenticity of the declaration:

• Verification of bank foreign exchange receipt: Require the agency company to provide the foreign exchange receipt slip for comparison with the amount on the customs declaration form.
• Verification of the tax - refund form: Check the invoice code through the VAT invoice verification platform of the State Taxation Administration.
• Third - party verification service: Use a third - party data service provider certified by the customs (such as the EDI data verification service of COSCO Shipping).

V. What are the new changes in customs declaration form queries in 2025?

According to the latest policy adjustments, special attention should be paid to:

• Strengthening of electronic signatures: When querying the customs declaration form, the electronic signature of the agency company needs to be verified simultaneously (the original paper authorization letter has been discontinued).
• RCEP special inquiry: For exports to ASEAN countries, the filing information of the certificate of origin declaration can be viewed.
• Data security restrictions: For customs declaration forms with a single - ticket cargo value exceeding $500,000, a security certification needs to be applied for to download the PDF version.
• Green - channel service: AEO advanced certified enterprises can enjoy the 7×24 - hour real - time data query permission.
