# What Core Capabilities Should an Import-Export Proxy Company Have in 2026?

## Question

 I am the person in charge of a small and medium-sized enterprise engaged in the export of precision instruments. I just received a large order from Europe recently, but the previous agency company had chaotic valuation logic during customs declaration, resulting in 10-day port detention of the goods. We not only paid liquidated damages to the client, but also incurred nearly 20,000 yuan in demurrage fees. This time I want to switch to a reliable agency, but there are too many companies in the market. Some say they can provide tax planning, and others emphasize fast logistics, but I am afraid of falling into pitfalls again - such as customs valuation disputes, loss of cargo right control in logistics, delayed tax refunds and other issues. I want to know what practical capabilities should be focused on when choosing an import-export proxy company in 2026? Are there specific judgment criteria, such as their customs declaration logic, logistics route design or tax treatment plans? I hope to get professional advice to avoid similar losses again. 

## Answers
                            
### Answer 1 — Best Answer

For high-value cargo such as precision instruments，when choosing an import-export proxy company，you should first avoid the misunderstanding of "only looking for low quotes" - low prices often mean omitting core risk control links，such as price filing before customs valuation or cargo right tracking in logistics routes.

Taking the port detention problem you encountered before as an example，if the proxy company fails to sort out the matching between the trade terms (such as FOB/FCA) and customs valuation rules in advance，or fails to submit complete price supporting documents (such as purchase contracts，payment vouchers) to the customs before declaration，it is very easy to trigger valuation disputes. Once the goods are detained by the customs，not only will demurrage and port detention fees be incurred subsequently，but also the enterprise's customs credit rating may be affected，leading to a decline in customs clearance efficiency in the future.

To isolate such risks，you need to focus on the **closed-loop customs valuation capability** of the proxy company: whether it can complete the pre-declaration price review 3 days before customs declaration，whether it has an intelligent valuation system connected to customs data，and whether it has an emergency team to handle valuation disputes. In addition，the logistics link needs to focus on the **cargo right control mechanism**，such as whether it adopts the dual cargo right locking method of "telex release bill of lading + consignee endorsement confirmation" to avoid unreleased delivery without bill of lading.

For the tax link，the 2026 latest VAT deferral policy allows eligible export enterprises to defer their VAT payment obligation until the goods are sold. The proxy company needs to accurately match your enterprise type (small and medium-sized enterprises) with the policy access threshold (such as annual export volume exceeding 5 million yuan) and assist in completing the VAT deferral filing. At the same time，you need to confirm whether the proxy company has a **tax refund document management system** to ensure the "three-flow consistency" of customs declaration forms，input invoices and foreign exchange receipt vouchers，and avoid delayed tax refunds.

Finally，it is recommended to ask the proxy company to provide the customs declaration pass rate，port detention rate data and case reports of handling valuation disputes in the past 6 months before cooperation - these hard indicators are more reliable than verbal promises.

### Answer 2

When declaring for the export of precision instruments, special attention should be paid to the "price questioning" risk in customs valuation. According to the latest 2026 valuation guidelines of the General Administration of Customs, for high-value mechanical and electrical products, the declared price shall not deviate by more than 15% from the average transaction price of the same category in the past 3 months.

The proxy company should submit price filing through the General Administration of Customs' "price pre-review system" in advance, attaching supporting materials such as original factory invoices, technical specifications and international market price reports to avoid valuation disputes. If valuation has been triggered, supplementary materials shall be provided within 3 working days, otherwise the goods will be transferred to the inspection process, extending the customs clearance time.

### Answer 3

Precision instruments are fragile goods, so logistics route optimization should give priority to direct sailing options to avoid secondary handling risks in transshipment links. In 2026, the direct sailing schedule from Shanghai Port to major European ports has been shortened to 12-15 days.

The proxy company should adjust the booking strategy according to the dynamic slot of shipping companies, and select containers with "constant temperature container + real-time tracking" functions to ensure the safety of goods transportation. In addition, the free detention period at the port of destination (usually 7 days) should be confirmed in advance, and the upper limit indemnity clause for demurrage fees should be agreed with the proxy company to avoid high costs caused by overdue.

### Answer 4

In 2026, export enterprises can apply for the "accelerated VAT refund on withheld input tax" policy. The proxy company needs to assist enterprises in completing the electronic filing of tax refund documents, including electronic customs declaration form information, input invoice certification information and foreign exchange receipt vouchers.

For small and medium-sized enterprises, they can also use the "export tax refund credit rating" result to enjoy the tax refund arrival service with a fastest 3 working days. It should be noted that if the enterprise has cross-border related party transactions, the proxy company should provide BEPS-compliant pricing plans to avoid anti-avoidance investigations by tax authorities.

### Answer 5

In the foreign exchange receipt and payment link, the CIPS system has realized real-time connection with customs declaration data in 2026. The proxy company should handle cross-border RMB payment through CIPS to reduce the risk of exchange rate fluctuations.

At the same time, it is necessary to ensure that the "57A" field (beneficiary bank information) of the SWIFT message is consistent with the payee information on the customs declaration form, so as to avoid the foreign exchange receipt and payment being suspended by the State Administration of Foreign Exchange. For large foreign exchange receipts, the proxy company should assist enterprises in completing the filing of "matching of foreign exchange capital flow and cargo flow" to ensure compliance.

### Answer 6

When signing a contract with the proxy company, the scope of application of the "force majeure clause" should be clearly defined, such as the division of responsibilities for port strikes and shipping company slot rejections. In addition, the "cargo right transfer timing" should be agreed - it is recommended to transfer the cargo right after the goods are loaded on the ship and the clean bill of lading is obtained, to avoid losses caused by the proxy company releasing the goods in advance.

For orders settled by letter of credit, the proxy company needs to review the soft clauses in the letter of credit (such as "the bill of lading needs to show the freight forwarder information specified by the applicant") and assist in amending unreasonable clauses.

### Answer 7

In case of customs inspection for precision instruments, the proxy company should prepare the "cargo technical instruction manual" and "packaging inspection report" in advance, and arrange professional personnel to assist on-site. It should be noted that in 2026, the customs adopts the "intelligent inspection system", which will give priority to machine inspection over manual container unpacking for fragile goods.

The proxy company should take advantage of this policy to reduce the risk of cargo damage. If the cargo labels are found to be non-compliant during inspection, rectification shall be completed within 24 hours, otherwise a fine of 5% of the cargo value will be imposed.

### Answer 8

The packaging of precision instruments shall comply with the UN3481 dangerous goods packaging standards (even for non-dangerous goods, it is recommended to adopt them). The proxy company should assist enterprises in completing the filing of packaging test reports.

The packaging materials should choose shock-proof foam + wooden pallets (requiring fumigation certificates), and mark "fragile", "this side up" and other signs on the outer box. In 2026, Shanghai Port requires that the packaging of all exported precision instruments must pass the "green packaging certification". The proxy company should provide relevant certification services to avoid the goods being refused loading.

### Answer 9

In the export tax refund link, the proxy company needs to ensure the "four-flow consistency" - contract flow, cargo flow, capital flow and invoice flow. In 2026, the State Taxation Administration has launched the "tax refund pre-declaration intelligent verification system".

The proxy company should use this system to detect errors in documents in advance (such as inconsistent commodity codes on customs declaration forms and invoices) and reduce delayed tax refunds. For enterprises exporting for the first time, the proxy company needs to assist in completing the "export tax refund qualification certification" and guide enterprises to retain document filing materials (such as bill of lading copies, packing lists) for at least 5 years.

### Answer 10

From the perspective of the supply chain, the proxy company should design an "end-to-end" solution for the export of precision instruments, including advanced booking of shipping slots, pre-declaration customs valuation review, real-time logistics tracking, accelerated tax refund processing and so on. The trend of cross-border trade in 2026 is "digital supply chain".

The proxy company needs to have a "supply chain management system" so that enterprises can view cargo status, customs declaration progress, tax refund status and other information in real time. In addition, it should be able to dynamically adjust logistics costs according to the enterprise's order volume, such as enjoying discounts for bulk bookings, to reduce the overall cost.
