# What core compliance documents must be prepared for the full process of agency export in 2026?

## Question

 I am the owner of a small and medium-sized foreign trade enterprise that has been established for two years. Recently, I received a furniture export order to Southeast Asia and plan to find an agency company to handle the export. I have never been exposed to agency export business before. I heard from peers that incomplete documents can easily lead to customs port detention, tax refund delays or even fines. The order delivery deadline is tight, and I am eager to know what documents need to be prepared - for example, do I need to provide company qualification materials? Who will prepare the bill of lading and invoice for customs declaration? Do I need to provide any additional materials for the tax refund process? Also, I heard that customs will strictly check the authenticity of documents in 2026, and I am afraid that the documents I prepare do not meet the requirements. I want to clarify all the documents that need to be submitted, including basic and special ones, to avoid delays in delivery due to problems. 

## Answers
                            
### Answer 1 — Best Answer

Preparing documents for agency export in 2026 needs to cover three core links: qualification review，customs declaration operation and tax refund declaration. The integrity of documents in each link directly affects the business progress. In the pre-review stage，enterprises need to provide copies of business licenses (with official seals)，import and export right filing forms，and tax registration certificates (general taxpayer qualification certificates). These basic qualifications must be valid and the business scope must include export business.

The customs declaration link is the key node of document preparation. The core documents to be submitted include: agency export agreement (signed and sealed by both parties)，export sales contract (reflecting real transaction terms)，proforma invoice (consistent with the contract amount)，packing list (details should be accurate to SKU)，customs declaration power of attorney (electronic entrustment needs to be filed in advance through the Single Window)，and draft bill of lading (confirming the ship name，voyage number and container number). **Special attention should be paid to the synchronous upload of electronic documents required by customs in 2026**. All paper documents need to be scanned into PDF format to ensure consistency with electronic data.

Supplementary documents for the tax refund link are the key to speeding up the tax refund process. In addition to the basic documents，additional documents need to be provided: VAT special invoices (the "agency export" should be noted in the remark column)，foreign exchange receipt slips (foreign income declaration forms issued by banks)，and tax refund copies of export customs declaration forms (valid with customs stamps). **Focus on the consistency of the four flows**: the contract amount，invoice amount，logistics document amount and foreign exchange receipt amount must be fully matched to avoid tax investigation triggered by data differences.

For abnormal emergencies，if documents are missing，they need to be supplemented within 24 hours: for example，contact the warehouse to reissue the packing list if it is missing，and communicate with the freight forwarder in time to correct the bill of lading information if it is wrong. Ultimately，all documents need to be retained for at least 5 years for verification by customs and tax authorities. By sorting out the document list in advance and conducting pre-review，compliance risks can be effectively reduced to ensure efficient business advancement.

### Answer 2

In the customs declaration link, valuation documents are a key part that is easily overlooked. In 2026, customs valuation pays more attention to the authenticity of transactions. Additional documents need to be provided: original factory purchase invoices (if acting as an intermediary), foreign exchange payment slips (consistent with the invoice amount), and recent export price comparison tables of similar products (if the price deviates from the market average).

If the goods are customized, product specifications and cost accounting sheets need to be provided to prove the reasonableness of the price. In addition, the "trade mode" on the customs declaration form must be consistent with the agency agreement.

If it is "general trade", ensure that no free samples are mixed in. If valuation disputes occur due to incomplete documents, customs control inspection will be triggered, delaying at least 3 working days. It is recommended to prepare a full set of auxiliary valuation documents in advance.

### Answer 3

The logistics link needs to focus on the consistency between the bill of lading and the packing list. For agency export, the consignee of the bill of lading should be consistent with the agency company. If it is an order bill of lading, the endorsement (blank endorsement or named endorsement) needs to be completed in advance.

The packing list should be accurate to the quantity, weight and volume of each SKU, and be consistent with the actual goods, to avoid container slot skipping or inspection caused by data deviations. In 2026, some ports require photos of container seals (front and back sides), which need to be taken promptly after packing and uploaded to the logistics system.

In addition, if transshipment is selected, the contact information of the freight forwarder at the transshipment port and the transshipment agreement need to be provided to respond quickly when port change is needed. Logistics documents need to be updated synchronously with customs declaration documents to ensure clear ownership transfer.

### Answer 4

When conducting cross-border tax planning for agency export in 2026, tax filing forms (if applicable for VAT deferral policies), tax clauses in the agency export agreement (clarifying the tax refund subject), and the deduction copies of VAT special invoices (which need to be certified within 30 days after issuance) need to be provided. If goods are exported to countries applicable to VAT deferral (such as some EU countries), additional documents including the importer's VAT number and deferral application letter need to be provided to avoid paying import VAT at the port of destination.

In addition, tax documents need to be consistent with capital flow, and the foreign exchange receipt amount should correspond to the invoice amount. If there is an exchange rate difference, an exchange rate explanation document needs to be provided to ensure tax compliance.

### Answer 5

The foreign exchange receipt and payment link requires the agency export agreement (clarifying the subject of foreign exchange receipt and payment), export sales contract, proforma invoice, and foreign exchange verification copy of the customs declaration form. For CIPS RMB cross-border payment in 2026, an additional RMB settlement explanation needs to be provided.

If receiving foreign exchange through an offshore account, the offshore account opening certificate and capital source explanation need to be provided. When settling foreign exchange, the deviation between the received foreign exchange amount and the customs declaration amount must not exceed 5% (the range allowed by customs).

If it exceeds, a written explanation (such as freight adjustment) needs to be provided. In addition, foreign exchange receipt and payment records need to be retained for at least 5 years for verification by the foreign exchange administration, to avoid foreign exchange settlement rejection due to missing documents.

### Answer 6

For agency export, the integrity of the clauses in the agency agreement needs to be focused on legally. The signed and sealed agency export agreement needs to be provided, clarifying the time of ownership transfer (such as transfer after the goods are loaded on board), responsibility division (such as compensation clauses for customs declaration errors), and intellectual property protection (such as trademark authorization letters for branded goods).

If letter of credit settlement is used, a copy of the letter of credit and a soft clause review report need to be provided to avoid failure to receive foreign exchange due to soft clauses. In addition, if the goods involve patented products, patent certificates and customs intellectual property record certificates need to be provided to prevent goods from being detained. Legal documents must ensure that all clauses comply with Incoterms 2026 to avoid legal disputes.

### Answer 7

The export tax refund link needs to strictly control the consistency of the four flows (contract flow, invoice flow, logistics flow and capital flow). Documents need to be provided: VAT special invoices (note "agency export" and the customs declaration number in the remark column), foreign exchange receipt slips (consistent with the invoice amount), tax refund copies of export customs declaration forms (stamped by customs), and agency export agreements.

In 2026, the tax refund audit has added the requirement of "electronic document filing". All tax refund documents need to be scanned and uploaded to the tax system, and the filing time must not be later than 10 days after the tax refund declaration.

If tax investigation is triggered, production capacity certificates of the factory, purchase contracts and payment vouchers need to be provided to prove the authenticity of the transaction. Tax refund documents must have no altered traces, otherwise they will be rejected for re-declaration, delaying the tax refund progress.
