# Full-process US Export Agency Services, Backed by Zhongshen's 20 Years of Industry Experience

## Current Status of US Market Exports and Core Challenges

The US import regulatory system continues to be strengthened in 2026.The random inspection rate for low-value goods by CBP has increased to 15%,and the access review cycle for food,medical devices and cosmetics by FDA has been extended to 45-60 working days.Meanwhile,the coverage of the Section 301 tariff list has been expanded to categories including electronic components and mechanical accessories,with an average tax rate ranging from 7.5% to 25%.Export enterprises generally face three major pain points: first,the risk of inspection and cargo detention caused by inconsistent documents; second,the risk of a $5,000 fine due to overdue ISF filing; third,the pressure of capital occupation caused by the export tax refund cycle being extended to more than 90 days.General Manager Yin mentioned that an auto parts enterprise in the Yangtze River Delta had its cargo detained at the Port of Los Angeles for 22 days last year due to incorrect HTS code classification,resulting in over $120,000 in port demurrage and document amendment fees.

## Core Values of Zhongshen’s Export Agency Services

Since its establishment in 2006,Zhongshen has handled over 30,000 TEU of cargo on US routes,and is familiar with the customs clearance characteristics and inspection rules of major US ports including Los Angeles,Long Beach,New York and Savannah.The core value of our services is reflected in three aspects: Pre-positioned compliance review mechanism,which completes FDA registration number verification,EPA certification matching and Section 301 tariff exclusion application assessment at the booking stage; Dynamic risk early warning system,which tracks CBP policy updates and port congestion indexes in real time,and adjusts declaration strategies 72 hours in advance; Capital efficiency optimization scheme,which shortens the normal tax refund cycle to within 45 working days through direct connection with the electronic port and green channel of the tax bureau.This full-process embedded mode avoids the information gap caused by segmented operations of traditional freight forwarders and customs brokers.

## Service Module Breakdown and US Policy Response

### Customs Declaration and Inspection Module: Pre-review of HTS Codes and Access Certifications

US Customs has extremely strict requirements for cargo description,and vague declaration will trigger immediate inspection.Zhongshen has established a three-level review mechanism: The first level is for document clerks to check the consistency of cargo descriptions on commercial invoices,packing lists and purchase contracts; The second level is for customs affairs supervisors to perform pre-classification against the US HTS code library,focusing on checking tax numbers covered by Section 301 tariffs; The third level is for certification-involved products,for example,medical devices need to provide FDA 510(k) number,and food contact materials need to submit FCN filing.New requirements introduced in 2026 indicate that CBP has begun to use an AI text comparison system to perform semantic matching between declaration elements and physical labels,and a similarity lower than 85% will be determined as false declaration.General Manager Yin’s team once helped a customer exporting smart wristbands modify the product name from "watch" to "smart wearable device with heart rate monitor" in advance,successfully avoiding the high 14% tariff for watches.Based on an annual export value of $2 million,this directly saved $280,000 in tariff costs.

### International Transportation and Customs Clearance Module: Coordination of ISF and AMS Filing

The US "10+2" rule requires that ISF filing must be completed 24 hours before shipment,and the carrier’s AMS filing must also be submitted simultaneously.Time difference management has become the key: After receiving the customer’s booking entrustment,Zhongshen immediately launches the "dual-track filing" process,submitting AMS data to the shipping company on one hand,and pushing ISF information through a CBP-approved third-party platform on the other hand.For the purchase of US importer Bond,we provide two solutions: For customers with annual import value exceeding $100,000,we assist in applying for Continuous Bond with an annual fee of about $500; For customers with scattered orders,we purchase Single Transaction Bond on their behalf,costing about $50-100 per transaction.For port inspection,Zhongshen has established cooperation with 6 C-TPAT certified warehouses in Los Angeles and Long Beach,which can quickly transfer inspected goods to bonded warehouses to avoid high container detention fees.Data shows that in the first quarter of 2026,through this mode,the average release time of customers’ cargo was shortened from the conventional 5.8 days to 2.1 days.

### Foreign Exchange Settlement and Tax Refund Module: Exchange Rate Locking and Tax Refund Acceleration

US orders are usually settled in US dollars,and exchange rate fluctuations significantly erode profits.Zhongshen provides a combination tool of forward foreign exchange settlement and foreign exchange swap to help customers lock exchange rate costs at the time of signing the contract.For the export tax refund link,the core barrier is the difficulty in obtaining the "export certificate" receipt from US Customs.CBP usually takes 30-45 days to issue the "export confirmation letter",which directly leads to the delay of domestic tax refund declaration.Zhongshen adopts the strategy of "pre-declaration + parallel operation": Once the cargo is loaded,we immediately submit the tax refund filing to the tax bureau with the bill of lading,and start the procedure of urging the issuance of export certificate at the US end at the same time.Through the A-level taxpayer green channel established with the tax bureaus of Shanghai and Ningbo,we realize "refund first,verification later",and the tax refund can be received as early as 38 days after the cargo departs from the port.General Manager Yin shared that after a furniture export enterprise adopted this mode,its annual capital turnover rate increased from 4.2 times to 6.8 times,and financial costs decreased by 37%.

## Efficiency Improvement and Risk Control Practices

The improvement of customs clearance efficiency relies on information pre-positioning and process standardization.Zhongshen has developed a special SOP manual for US exports,which shortens the document preparation time for conventional cargo from 48 hours to 6 hours.For "random inspection" by US Customs,we have established a "red,yellow and blue" three-level risk labeling system: Blue label cargo (low risk,such as ordinary hardware parts) adopts the "instant release" mode,and red label cargo (high risk,such as goods subject to Section 301 tariffs) activates the expert consultation mechanism.For tax refund speed,the core breakthrough lies in "document electronization" and "data cross-verification".Through OCR recognition technology,US invoices and packing lists are converted into structured data,which are automatically compared with domestic procurement invoices to ensure the accuracy rate of "three documents matching" reaches 99.2%,avoiding tax refund review rejection caused by inconsistent data.Data from 2026 shows that the average customs clearance time of customers is shortened by 58%,and the tax refund cycle is accelerated by 42%.

| Service Module | US Policy Barriers | Zhongshen’s Response Strategy | Efficiency Improvement Indicator |
| --- | --- | --- | --- |
| Customs declaration and inspection | HTS code classification disputes,FDA access review | Three-level pre-review,certification database matching | 99.5% declaration accuracy,60% lower inspection rate |
| Transportation and customs clearance | ISF overdue fine,port congestion and inspection | Dual-track filing,C-TPAT warehouse reserve | Release time reduced from 5.8 days to 2.1 days |
| Foreign exchange and tax refund | Delayed export certificate receipt,exchange rate fluctuation | Pre-declaration + green channel,forward exchange rate locking | 38-day tax refund cycle,exchange rate risk locked |

## Customized Service Selection Suggestions

Policies for exports to the US vary significantly across different product categories,so the selection of agency services should match one’s own needs.Textile and garment enterprises should focus on CPSC combustion performance testing and origin labeling compliance; Machinery and equipment enterprises need to check whether they are subject to ECCN control; For food and agricultural product enterprises,FDA registration and Prior Notice are the core checkpoints.Zhongshen provides three cooperation modes: Full trusteeship mode,suitable for production enterprises without import and export operation rights,we act as agent to complete all links from foreign exchange receipt to tax refund; Module outsourcing mode,suitable for enterprises with self-operated export rights but lack of US customs clearance experience,who can entrust ISF filing or tax refund acceleration services separately; Consultant mode,for large customers with annual export value exceeding $5 million,we provide policy interpretation and customized risk contingency plans.General Manager Yin suggests that enterprises can first experience the operation process of a single shipment through a trial order,and then select the most suitable service combination according to their own team capabilities and export scale.The US market has complex rules but considerable profits.The value of professional agencies lies in converting uncertainty into predictable cost and time nodes,allowing export enterprises to focus on product R&D and market expansion.
