Complete Guide to Avoid Mistakes in Filling Import Freight Forwarding Commission Forms

Import Freight Forwarding Commission Form: 3 Core Risks and 5-Step Compliance Operation Guide

Last year,Mr.Lv imported precision instruments from Germany.There were 2 discrepancies between the declaration elements on the commission form and the actual model,which caused a 3-day inspection delay at Shanghai Port and incurred nearly RMB 5,000 in port demurrage charges.This is a typical chain reaction caused by non-standard filling of commission forms.As an agent with 20 years of in-depth operation experience at Shanghai Port,I have seen too many enterprises hit the "regulatory red line" in the customs clearance process due to missing or incorrect information on commission forms.

I.Critical Rules for Filling Core Elements of Commission Forms

Every piece of information on the commission form may become a "trigger" for customs valuation or inspection.The following 3 high-frequency errors should be avoided with priority:

• HS Code Classification Discrepancy: A chemical product commission form incorrectly filled "alcohols" as "hydrocarbons",leading to a judgment of abnormal price during valuation.As the enterprise failed to provide proof of the average market price of similar products,it finally paid more than RMB 200,000 in supplementary taxes.In 2026,customs supervision over newly added tariff headings (such as 38249090) is tightened.It is recommended to verify the accuracy of the code through the "Advance Ruling on Classification" system in advance.
• Conflict Between Trade Terms and Declaration Data: Under FOB terms,the commission form did not specify FOB details and only filled in the CIF price.When customs reviewed it under the "transaction value method",due to the lack of basis for separating freight and insurance premiums,it directly calculated tax based on the Most Favored Nation average price,causing the enterprise to pay 15% more tariffs.
• Mismatch Between Declaration Elements and Actual Goods: An import commission form for medical devices did not fill in the "medical device registration certificate number",which made it impossible for the port to verify product compliance online.The goods were finally ordered to be returned for "import without certificate",resulting in return costs and late delivery penalties.

II.Risk Breakdown of the Full Customs Clearance Process at Shanghai Port

Based on the latest 2026 regulatory requirements,import commission forms need to cover four key nodes:

Special reminder: For goods imported from RCEP member countries in 2026,tariff reduction or exemption can be applied for with the "declaration of origin".The commission form shall clearly mark the type of "RCEP Certificate of Origin (Form R)",and "RCEP Preference Enjoyment" shall be filled in the remark column of the customs declaration form.

III.5-Step Self-Inspection Checklist and Practical Risk Avoidance Cases

The following is the verified "5-step self-inspection method for commission forms",which can greatly reduce customs clearance risks:

• Verify trade terms and transport clauses: For EXW terms,the factory packing time shall be specified; for FOB,the port of loading code (such as CNSHA) shall be marked
• Confirm the completeness of declaration elements: Brand (including trademark),model (including specification parameters),material (fill in truthfully such as alloy/pure gold)
• Verify special supervision documents: If used mechanical and electrical products are involved,the number of the Pre-shipment Inspection Certificate for Imported Used Mechanical and Electrical Products shall be attached
• Mark the party responsible for expenses: Clarify whether ocean freight and insurance premiums are included in the total CIF price to avoid double charging by freight forwarders
• Retain the agency agreement: The scope of agency services of Zhongshitong shall be specified to avoid disputes caused by unclear division of responsibilities

Practical Case: An enterprise imported auto parts from Japan,and the import license number was missing on the commission form,resulting in the port being unable to release the goods.Action: Immediately contact the agent to supplement the license information and submit a scanned copy of the Import License Application Form.Result: The order was returned and re-declared within 3 hours,avoiding more than RMB 30,000 in port demurrage charges.

IV.2026 New Risk Warning

With the launch of the Customs "Single Window" 2.0 system,the following risks shall be prevented with priority:

• Document Exchange Fee Trap: Freight forwarders often increase charges in the name of "document exchange fee".It is recommended to specify the "maximum document exchange fee" in the remark column of the commission form (no more than RMB 500 per shipment according to Shanghai Port standards)
• Demurrage Liability: The "cut-off time" is not specified when booking space,resulting in the goods being detained at the port for more than 48 hours after arrival.The "latest cut-off date" and the responsible party shall be marked on the commission form
• Penetrating Data Verification: Since 2026,customs has extremely high requirements for the matching degree between "declaration elements and actual goods photos".Clear multi-angle photos of the product shall be attached to the commission form

Conclusion: The import freight forwarding commission form is the "pass" for goods entering the country,and every detail may affect the efficiency and cost of customs clearance.As an agent for Shanghai Port,we recommend that enterprises conduct self-inspection against the above list before entrustment,or directly contact Zhongshitong (Tel: 139-1777-6136) for free pre-review services.
