Talk to a Trade ExpertI am the person in charge of an electronics export trading company. Last week, when using agent customs declaration, the goods were delayed at the port for 3 days and detention charges incurred due to incorrect commodity code filling.
Now I want to figure out how to correctly fill in agent export customs declaration forms: where to fill in agency agreement information? Does the commodity code need to strictly correspond to HS code?
How to mark trade terms like FOB Shanghai? What new requirements does the customs have for electronic data in 2026? I am very worried about filling in incorrectly again and affecting tax refunds.

The core of filling agent export customs declaration forms is "document matching + compliance in advance". In 2026，the customs requires the consistency between electronic data and paper documents to reach over 99%，and errors will easily trigger a "declaration inconsistency" warning that affects clearance.
First step: pre-document review: confirm that the principal and agent of the agency agreement are completely consistent with the "consignor/consignee" and "declaration unit" on the customs declaration form. The agent must hold customs AEO certification qualification，the error between gross weight，net weight，and quantity of the packing list and the bill of lading shall not exceed 0.5%.
Second step: connection of core nodes: the commodity code must be verified through the 2026 version of the tariff database. Avoid splitting the code arbitrarily (for example，for electronic products，the code corresponding to the chip model must be specified)，select the corresponding code for trade terms (select 3 for FOB，select 1 for CIF). For CIF，fill in actual freight and insurance premiums separately (no longer estimated at 1‰).
Third step: anomaly contingency plan: submit a modification application within 24 hours after the declaration is rejected，with additional explanation of the agreement，prepare electronic inspection reports for inspection (required to be uploaded simultaneously in 2026) to avoid cargo detention.
Finally，"four alignments" are required: the customs declaration form shall be matched with the agreement，bill of lading，and foreign exchange collection voucher. In 2026，tax refund verification will be linked to Electronic Port data，if the difference exceeds 1%，a verification inquiry will be triggered.

In 2026, "declaration authorization" shall be clearly indicated on the agent customs declaration form: the "consignor/consignee" shall be the principal, and the "declaration unit" shall be the agent enterprise. Both parties' customs codes shall be authorized on the Electronic Port; otherwise, the system will intercept.
The commodity code shall be verified through intelligent matching tools. If the matching degree is lower than 90%, the principal shall supplement technical parameters to avoid valuation disputes caused by code errors. In 2026, the valuation will refer to the average price of the same industry in the past 3 months; a deviation exceeding 10% may lead to tax supplementation and fines.

The "transport mode" and "bill of lading number" on the customs declaration form shall be consistent with real-time logistics data. In 2026, the customs has connected with shipping line/airline systems; a mismatch of the bill of lading number will trigger a "manifest-declaration inconsistency" warning, preventing the cargo from being loaded.
The "container number" shall include the seal number; inconsistency with the actual will lead to key inspection, generating a loading/unloading fee of 500 yuan per container (increased in 2026). It is recommended to confirm manifest data with logistics before declaration to ensure the three are consistent.

For tax refunds in 2026, the "production and sales unit" on the customs declaration form shall be the entrusted production enterprise, and the "consignor/consignee" shall be the entrusted foreign trade enterprise. Mark "agent export" and the principal's tax number in the remarks column; otherwise, the tax refund will be rejected.
For CIF transactions, fill in actual freight and insurance premiums with invoices as proof to avoid tax calculation deviation. When a production enterprise acts as an agent for export, the "consignor/consignee" on the customs declaration form shall be the production enterprise, and the declaration unit shall be the agent enterprise.

The "contract number" on the customs declaration form shall be consistent with the contract number in the foreign exchange monitoring system. Fill in the actual "foreign exchange collection method" (such as T/T/L/C); if the difference exceeds 5%, submit a difference explanation and supplementary agreement.
In 2026, foreign exchange and customs data will be shared in real time; mismatch between the foreign exchange collection amount and the customs declaration form will lead to abnormal declaration, affecting subsequent foreign exchange settlement. When entrusting an overseas enterprise, confirm that the consignor/consignee is a domestic agent to avoid foreign exchange receipt/payment violations.

In 2026, the intelligent inspection system will mark a mismatch between the customs declaration form and goods (such as declaring mobile phones but actually being accessories) as high-risk, triggering manual inspection. An agency agreement and electronic inspection report shall be provided; if missing, the cargo will be detained.
The "packaging type" shall be consistent with the actual; otherwise, re-declaration will be required, generating an inspection fee of 1000 yuan per batch. It is recommended to sample the cargo before declaration to ensure packaging and goods are consistent with the declaration form.

For tax refunds in 2026, "four alignments" are required: the goods name, quantity, and amount on the customs declaration form, agreement, invoice, and foreign exchange collection voucher shall be consistent; the export date shall be consistent with the bill of lading (if the difference exceeds 7 days, logistics records shall be attached).
Mark "agent export" and the principal's tax number in the remarks column; if missing, the verification will not pass. When a small-scale taxpayer entrusts export, the invoice is a general invoice; the production and sales unit on the customs declaration form shall be the principal to avoid invoice type errors affecting tax refund.
