I am a new practitioner in foreign trade. Last week, I hired an agent to declare a batch of electronic products for export for the first time, but the "trade mode" was filled incorrectly on the customs declaration form, resulting in the cargo being detained at the port for 3 days and incurring detention fees. Now I need to declare a batch of chemical products, and I heard that the customs has new requirements for the columns of agency customs declaration forms in 2026? I want to know how to fill in the agency export customs declaration form specifically to be compliant?
For example, which number should be filled in the "agency agreement number"? Should the "FOB price" be the price in the agency contract or the actual transaction price? Also, do I need to pay special attention to the "commodity code" of chemical products? Will I be inspected and the cargo detained if I fill it incorrectly? Are there any practical skills to avoid mistakes?

The filling of agency export customs declaration forms should be implemented from four links: pre-declaration document verification，accurate filling of core columns，node connection management and control，and exception response plan，to avoid problems such as port detention caused by incorrect trade mode filling as you encountered before.
First，pre-declaration verification: You need to first check the agency agreement (the 2026 new rules require the agreement number to be consistent with the customs record)，packing list，invoice，and commodity code (for chemical products，you need to confirm whether they fall into the scope of supervision certificates，for example，dual-use items need to be filed in advance). Focus on confirming whether the "consignor" column should be filled with the agency company or the actual manufacturing enterprise. Note: Starting from 2026，the consignor on the agency customs declaration form must be filled with the actual export enterprise，and the agency company should be filled in the "declaration unit" column to avoid subject errors.
Key points for filling core columns: 1. Trade mode: If the agency export is general trade，fill in "general trade"，if it is processing with imported materials，provide the manual number，2. FOB price: Must be filled with the actual transaction FOB price，excluding agency service fees. If it is included，it needs to be split (the customs will conduct stricter verification on the consistency between FOB price and foreign exchange receipt amount in 2026)，3. Commodity code: For chemical products，it must be accurate to 8 digits. If you are not sure，you can check through the 2026 version tariff schedule of the General Administration of Customs to avoid incorrect tariff calculation caused by code errors，4. Agency agreement number: Fill in the agency agreement number filed with the customs，not the internal contract number. If there is no record，you need to handle it in advance (some ports support online filing).
Node connection: Before declaration，confirm with the agency company whether the "declaration elements" are complete (such as MSDS number，ingredient content of chemical products). Before machine inspection，confirm that the weight and quantity of pieces on the packing list are consistent with those on the customs declaration form. If inspection occurs，cooperate to provide supplementary documents (such as original agency agreement，production records).
Exception response plan: If you fill in incorrectly，apply for "delete and re-declare" before customs release. Starting from 2026，deleting a declaration requires providing an error explanation and a seal certification from the agency company to avoid late declaration fees caused by exceeding the declaration period，if you find the error after release，apply for "declaration amendment"，and need to provide correction materials (such as corrected invoice，supplementary explanation of the agency agreement). The amendment cycle is generally 3-5 working days.
Practical skills: You can first conduct simulated declaration through the "Single Window" of the General Administration of Customs to check whether the declaration elements match，for chemical products，apply for "pre-classification" in advance (some agency companies can assist) to avoid cargo detention due to code disputes during on-site inspection，keep all documents (customs declaration form，agency agreement，invoice，packing list) for at least 5 years to respond to tax correspondence verification (the tax authority will conduct more detailed verification on the consistency of documents for agency exports in 2026).

When declaring agency customs declaration forms in 2026, pay attention to the distinction between "declaration unit" and "actual export enterprise". If they are filled reversely, the customs system cannot match the agency relationship, which will trigger price verification. In addition, if the trade mode column is filled with "entrusted agency export" (old column), it has been adjusted to "general trade" (under agency mode) in 2026.
You need to confirm whether the "entrusted export" clause is specified in the agency agreement, otherwise the declaration will be rejected. In case of price verification disputes, provide proof of the actual transaction FOB price (such as bill of lading, foreign exchange receipt slip) to avoid the customs levying tax according to the minimum price limit.
Delete and re-declare must be operated before the cargo leaves the port. If the cargo has left the port, you need to apply for "declaration amendment", and provide the corrected invoice, packing list and a situation explanation sealed by the agency company. The cycle is about 3 working days.

The "bill of lading number" in the customs declaration form must be consistent with the bill of lading issued by the shipping company. Incorrect filling will lead to failure to exchange the bill for picking up the cargo, resulting in container detention fees (the daily container detention fee in some ports will increase by 0.5% in 2026). In addition, the "port of shipment" should be filled with the actual loading port.
For transshipment cargo, fill in the "transshipment port code" to avoid container rolling caused by incorrect logistics routes. The free storage period should be indicated in the remarks column of the customs declaration form. If not indicated, there is no free storage by default, which will incur storage fees. It is recommended to confirm the bill of lading information with the freight forwarder in advance, check whether the number of pieces, weight and cargo description on the customs declaration form are consistent with those on the bill of lading before declaration, and correct them in time if they are inconsistent to avoid affecting cargo pickup.

The "FOB price" of the agency export customs declaration form must be consistent with the FOB price declared for export tax refund. In 2026, the tax authority will verify the difference between the amount on the customs declaration form and the foreign exchange receipt slip during correspondence verification.
If the difference exceeds 5%, a reasonable explanation (such as commission, discount) is required. In addition, the agency agreement should clearly specify the split between "agency service fee" and "cargo value". If there is no split, the tax authority will determine that the cargo value is overstated, which will affect the tax refund amount.
If chemical products fall into the scope of "levy and refund immediately", indicate "levy and refund immediately" in the remarks column of the customs declaration form and provide relevant qualification certificates, otherwise you cannot enjoy the tax refund preference. It is recommended to keep electronic copies of the agency agreement, invoice and foreign exchange receipt slip for tax verification.

When declaring agency customs declaration forms in 2026, pay attention that the "foreign exchange receipt subject" is consistent with the "actual export enterprise". If the agency company collects foreign exchange on behalf, an "agency foreign exchange collection agreement" is required, otherwise it will trigger the verification of the "Trade Foreign Exchange Receipt and Payment Enterprise Catalog" by the foreign exchange administration.
In addition, the "cargo description" in the customs declaration form must be consistent with the foreign exchange receipt invoice. If the difference in cargo description exceeds 10%, you will not be able to settle the foreign exchange. It is recommended to confirm the foreign exchange receipt subject with the bank in advance, check whether the cargo description and amount on the customs declaration form are consistent with those on the invoice before declaration, and correct them in time if they are inconsistent to avoid affecting foreign exchange settlement.

The customs declaration form must be consistent with the terms of the agency agreement. If the "customs declaration responsibility" is not specified in the agreement, it will lead to disputes. In 2026, the customs requires that the agency agreement must include the clause of "responsibility for filling customs declaration form".
If the agency company fills in incorrectly and causes losses, it shall compensate according to the agreement. In addition, if the "commodity code" in the customs declaration form is filled incorrectly, resulting in increased tariff, the responsible party shall be clarified (for example, the agency company did not fill in according to the actual cargo description). It is recommended to clearly specify the "verification responsibility for filling customs declaration form" in the agency agreement, keep the original agreement and the correction record of the customs declaration form to facilitate dispute resolution.

In 2026, the on-site inspection will conduct stricter verification on the consistency between the "commodity code" on the agency customs declaration form and the actual cargo. If the ingredient content of chemical products is inconsistent with that on the customs declaration form, it will be sent for inspection and identification, and the cycle is about 7 working days. In addition, the "seal number" in the customs declaration form must be consistent with the seal of the actual container.
If they are inconsistent, it will be suspected of cargo right transfer, resulting in cargo detention. It is recommended to check the seal number in advance, confirm that the cargo is consistent with the cargo description, code and ingredients on the customs declaration form before declaration. If inspected, cooperate to provide the original agency agreement and production records to avoid cargo detention.

The agency customs declaration form for chemical products should indicate the "packaging type" (such as UN packaging). If not indicated, it will fail to pass the machine inspection.
In 2026, the customs requires that the packaging of chemical products comply with the "Rules for the Transport of Dangerous Goods", and the "UN number" and "packaging grade" should be indicated in the remarks column of the customs declaration form. In addition, the MSDS number must be consistent with that on the customs declaration form.
If inconsistent, you will be required to provide supplementary MSDS. It is recommended to confirm the packaging type and UN number in advance, check whether the information on the MSDS is consistent with that on the customs declaration form before declaration to avoid failing the machine inspection.

In 2026, the export tax refund audit will conduct more detailed verification on the "consistency of four streams" (contract, invoice, customs declaration form, foreign exchange receipt) of the agency customs declaration form. If the "actual export enterprise" on the agency agreement is inconsistent with that on the customs declaration form, it will lead to tax refund failure.
In addition, the difference between the "declaration date" of the customs declaration form and the foreign exchange receipt date shall not exceed 180 days. If it exceeds, a reasonable explanation (such as force majeure) is required. It is recommended to confirm the foreign exchange receipt date in advance, check whether the four streams are consistent before declaration, and keep all documents for at least 5 years to facilitate audit verification.

The "trade term" (such as FOB, CIF) of the agency customs declaration form will affect the logistics cost. In 2026, some ports will conduct stricter verification on the freight of CIF customs declaration forms.
If the freight is inconsistent with the actual, it will lead to increased tariff. In addition, the selection of "port of shipment" and "port of destination" will affect the logistics timeliness.
It is recommended to plan the logistics route in advance and confirm that the trade term on the customs declaration form is consistent with that on the logistics contract. For transshipment cargo, indicate "transshipment" in the remarks column of the customs declaration form to avoid logistics delay.
