Legal Validity of Agent Import Confirmation Note: Core Document for Customs Audit

Legal Validity Boundary of Agent Import Confirmation Note: The "Invisible Threshold" for Customs Valuation

In the practice of agent import at Shanghai Port,the agent import confirmation note (hereinafter referred to as "confirmation note") is far more than a simple business confirmation document.It is the triple compliance basis for customs valuation,foreign exchange verification and tax refund filing,whose validity directly determines whether the goods can be smoothly customs cleared.We once encountered such a case: a chemical enterprise imported a batch of coatings through an agency,but as the confirmation note did not clearly mark the "non-dangerous packaging" attribute,the inspection and quarantine bureau conducted pre-inspection on the goods as hazardous chemicals,resulting in a 48-hour customs clearance delay.This lesson proves that the legal validity of the confirmation note is not only a legal text,but also the "safety lock" of the operation process.

I.Correlation Logic Between Confirmation Note and Customs Valuation

The customs valuation link has three core standards for validity verification of the confirmation note:

• Declared Price Matching: The CIF price on the confirmation note shall be consistent with that on the commercial invoice and bill of lading,otherwise price query will be triggered.The newly added 2026 "Price Deviation Warning System" will automatically compare the import data of the same HS code in the past 6 months.If the price on the confirmation note exceeds the threshold,the customs will launch manual valuation (for example,when a medical device was imported through agency,the price on the confirmation note was 15% different from similar products,resulting in a 3-day valuation delay).
• Trade Term Compliance: Under EXW terms,the confirmation note shall clarify the delivery responsibility at the factory; under FOB terms,the breakdown of freight and insurance premium allocation shall be marked.When a mechanical equipment was imported through agency,the confirmation note omitted the transportation responsibility from "factory in the exporting country to Shanghai Port",resulting in the return of the application by the bank during foreign exchange verification.
• Correlation Validity of Certificate of Origin: If the confirmation note marks "Origin: Malaysia",FORM M (RCEP Certificate of Origin) shall be submitted simultaneously,otherwise the tariff reduction cannot be enjoyed.

II.Validity of Confirmation Note in Pre-Inspection by Inspection and Quarantine Bureau

Special categories such as animal and plant quarantine and food inspection need to verify the validity of the confirmation note with priority:

• Food Products: The confirmation note shall clearly mark "production date + shelf life + importer record number".A batch of Southeast Asian nuts imported through agency was suspended for inspection by the inspection and quarantine bureau as the record number was not filled in the confirmation note.
• Medical Devices: The confirmation note shall be attached with ISO13485 certification statement.A batch of ventilators imported through agency was detained by the medical products administration as the statement was missing in the confirmation note.
• Animal and Plant Products: The official quarantine certificate issued by the exporting country shall be attached,and the confirmation note shall mark "no wooden packaging" or provide fumigation certificate.An importer failed to fill in the packaging declaration in the confirmation note,resulting in the return of 300 cases of goods.

IV.Zhongshitong Practical Guide: Confirmation Note Validity Guarantee System

As an agency with 20 years of experience at Shanghai Port,we have built a "three-dimensional verification system" to ensure the validity of confirmation notes:

• Pre-inspection of Documents: A full-time team of 5 members checks against the "2026 Edition Import Document Check List",focusing on verifying the consistency between declaration elements and actual goods (for example,when importing a batch of auto parts,we found and corrected the mistake in advance that HS code "8708" was incorrectly written as "8709" on the confirmation note).
• Port Linkage: We have established a "pre-classification channel" with 32 customs districts directly under the General Administration of Customs across China,to push the pre-classification audit result synchronously when submitting the confirmation note.
• Legal Endorsement: We have launched the "Confirmation Note Validity Insurance" in cooperation with Ping An Bank,covering losses such as port demurrage and fines caused by document defects.

V.Practical Resolution for Common Validity Disputes

An importer of mechanical equipment (Mr.Zhu) once got into trouble due to the confirmation note problem of the agency company: Scenario: The German machine tool equipment imported through agency was levied 15% tariff by the customs as "new equipment" because the confirmation note did not mark the attribute of "used equipment"; Task: Assist the enterprise to prove that the equipment is actually used and meets the declaration conditions; Actions: 1.Retrieve the original customs declaration document issued by the German manufacturer,2.Supplement the "Used Mechanical and Electrical Products Record Certificate",3.Apply for classification reconsideration; Result: The customs finally levied tariff at the tax rate for used equipment (5%),avoiding a total tariff loss of 2.8 million RMB.

This case proves that the validity of the agent import confirmation note is not static,but requires dynamic maintenance: not only to avoid document errors in the early stage,but also to respond quickly when disputes arise.

Legal and Operational Red Lines for Validity of Agent Import Confirmation Note

After the revision of the new Customs Law in 2026,the judicial recognition of confirmation note validity has become stricter.We have summarized three "untouchable" red lines:

• False Declaration Red Line: Contradiction between the confirmation note and certificate of origin (for example,marked as made in China but actually made in Japan) will directly trigger investigation by the customs anti-smuggling bureau.Zhongshitong has ever assisted enterprises in resolving such disputes,but the average handling period is 3 months,with daily demurrage cost of 2000 RMB.
• Data Tampering Red Line: If key data such as quantity and weight on the confirmation note are inconsistent with that on the bill of lading,the enterprise will be listed in the "key audit enterprise" list,and will not be eligible for the "aggregated duty payment" preferential policy within 3 years.
• Qualification Deficiency Red Line: For required import documents such as Automatic Import License (O Form) and China Compulsory Certification (3C Certification),the confirmation note shall mark "recorded" or provide the corresponding certificate,otherwise the goods will be detained until all documents are complete.

Final Reminder: The validity of the agent import confirmation note is essentially the epitome of an enterprise’s compliance capability.Rather than taking remedies after problems occur,it is better to establish a guarantee system of "double document review + legal backing" in the early stage.Zhongshitong will rely on 20 years of port on-site practical experience to act as the compliance firewall for your agent import business.
