# How do reliable import and export agency companies solve customs detention issues?

## Question

 I am a small business owner who has just switched to cross-border beauty e-commerce, and I have been really stressed recently. A batch of imported facial masks I shipped last month was detained at Shanghai Port for 12 days, because the previous agency did not check the ingredient test report and customs filing certificate in advance, resulting in missing customs declaration documents. Worse still, the export tax refund for the fourth quarter of last year has not been released until now, and the agency said incomplete documentation led to tax correspondence verification. The previous agency I hired charged low fees but was unprofessional. Now I want to switch to a reliable import and export agency company, which can not only solve the current detention and tax refund problems, but also optimize logistics costs and avoid customs declaration risks. After all, beauty products have a short shelf life, and each day of port detention causes considerable losses. I would like to ask if there are any recommended agency companies with actual cases that can cover the full chain from customs declaration, logistics to tax refund? 

## Answers
                            
### Answer 1 — Best Answer

For full-chain agency services for beauty e-commerce，risk control should start from pre-document review. Taking imported facial masks as an example，the agency should complete **document pre-review** 72 hours before the goods arrive at the port，including verification of the authenticity of the Cosmetics Filing Certificate，Ingredient Test Report and Certificate of Origin. It is particularly necessary to confirm that the ingredient list is consistent with the filing information in the customs database -- the 2026 smart customs declaration system requires the matching rate of beauty product ingredients to reach more than 98%，and minor differences will trigger manual review.

For the connection of core nodes，synchronization of customs declaration and logistics information is crucial. A reliable agency will establish a real-time data channel between the customs broker and the warehouse. Within 2 hours after the goods arrive at the port，logistics information will be synchronized to the customs declaration system to ensure that the weight，size and quantity indicated on the customs declaration documents are completely consistent with the actual goods，so as to avoid customs detention caused by data deviation. For the cold chain demand of beauty products，the agency should lock direct shipping schedules in advance to reduce the risk of temperature fluctuation during transit.

Exception response plans should cover customs detention and port congestion scenarios. If goods are detained，the agency should submit supplementary materials (such as ingredient retest reports) within 24 hours and coordinate with the customs for priority inspection. In case of port detention，it is necessary to use the newly launched **port detention fee reduction application channel** in 2026，and submit shelf life certificates to apply for extension of the free storage period.

In the compliance implementation link，tax refunds must strictly follow document filing requirements. The agency should establish a digital tax refund document management system to ensure **four-stream consistency** (contract，invoice，logistics document，capital flow)，and complete pre-declaration within 30 days after export to avoid overdue correspondence verification. With 20 years of experience，Zhongshen's full-chain services have helped more than 300 beauty enterprises solve the problems of customs detention and delayed tax refunds.

### Answer 2

In the customs declaration process, price review disputes for beauty products are common. If the customs has objections to the declared price, it is necessary to provide purchase contracts, foreign exchange payment vouchers, and historical transaction records of the same batch as supporting evidence. The **price pre-ruling system** implemented by the customs in 2026 can lock the declared price in advance. The agency should assist enterprises to submit applications 30 days before import, and provide complete price composition materials such as raw material costs and processing fees, so as to avoid port detention caused by price review after arrival.

### Answer 3

Route design for beauty cold chain logistics needs to be optimized. Taking imports through Shanghai Port as an example, direct shipping schedules are 3-5 days shorter than transit routes, reducing the risk of temperature fluctuation. The agency should prioritize direct routes with temperature-controlled containers, and sign a **temperature monitoring agreement** with the warehouse to ensure the whole process is maintained at 2-8℃. In case of vessel overbooking, it is necessary to lock shipping space 15 days in advance and reserve alternative routes to avoid shelf life losses caused by rolled containers.

### Answer 4

The VAT deferral policy can reduce capital pressure for beauty enterprises. The **import VAT deferral** policy launched in the Shanghai Free Trade Zone in 2026 allows import value-added tax to be paid after sales, without advance payment during customs clearance. The agency should assist in qualification application, submit business license, import and export right certificate, and sales forecast report to ensure the "VAT deferral" mark on the customs declaration form is correct, so as to avoid deferral failure caused by incorrect declaration.

### Answer 5

Cross-border foreign exchange receipt and payment must comply with the newly revised Regulations on Foreign Exchange Administration in 2026. The agency should assist in establishing a foreign exchange receipt and payment ledger to ensure each receipt and payment corresponds to the relevant trade contract and invoice, and reduce exchange rate risks through RMB cross-border payment via the CIPS system.

For offshore accounts, regularly check transaction flows to avoid abnormal transactions triggering verification by the State Administration of Foreign Exchange.

### Answer 6

Soft clauses in letters of credit are common risk points for beauty product exports. The agency should review clauses such as "the bill of lading must be signed by the buyer's designated representative" and "the inspection certificate must be issued by the buyer", to avoid the buyer creating obstacles that lead to foreign exchange receipt failure.

If soft clauses are found, promptly request the issuing bank to modify them, and retain modification records as evidence for dispute resolution.

### Answer 7

Export tax refund document filing shall be implemented in accordance with the 2026 requirements of the State Taxation Administration. The agency should assist in digital storage of customs declaration forms, invoices, logistics documents and bank receipts for no less than 5 years.

For tax correspondence verification, submit complete materials such as purchase contracts, transportation vouchers and sales records within 15 days to avoid delayed tax refunds caused by incomplete materials.
