# Mianyang Ocean Freight Agent for Exports to the US: Full Core Process Services and Policy Adaptation

## Market Status and Common Challenges of Mianyang Ocean Freight Exports to the US

As a key foreign trade city in Sichuan Province,Mianyang recorded a 12% year-on-year increase in exports to the US in 2026.Mechanical and electrical products (45% share),textile and apparel (28% share),and agricultural products (15% share) are the main export categories.Many Mianyang enterprises report that with the dynamic adjustment of US tariff policies and intensified fluctuations in ocean freight space,they often encounter the following problems during the export process: first,customs clearance delays caused by non-compliant documents; second,delivery delays due to congestion at US West Coast ports; third,delayed export tax refund processes caused by poor matching of US transaction data.

## Core Service Value of Zhongshen for Mianyang Exports to the US

Zhongshen has been deeply engaged in foreign trade agency services for over 20 years.Focusing on the pain points of Mianyang enterprises exporting to the US,we prioritize two core directions: "policy adaptation and process optimization".For example,for US tariff exclusion applications that Mianyang mechanical and electrical enterprises often encounter,Zhongshen has established a special docking mechanism; for FDA certification requirements for textile and apparel products,we sort out compliance checklists in advance.Mr.He,Head of the Document Department at Zhongshen,notes that many small,medium and micro enterprises in Mianyang are not familiar with the latest US trade rules,and our services are designed to help them eliminate risks before export.

## Disassembly of Core Service Modules and Response to US-Specific Policies

### 1.Document Compliance Services – Accurately Meet US ISF and Certification Requirements

US Customs has far stricter requirements for import documents than domestic customs.**ISF (Importer Security Filing)** is the core barrier – filing must be completed 24 hours before the goods arrive at the port,and more than 10 pieces of detailed information (such as supplier and manufacturer addresses,container seal numbers,etc.) are required.In addition,textile and apparel products exported from Mianyang that involve children’s products also require CPSIA certification; agricultural products must meet the inspection and quarantine requirements of the US Department of Agriculture (USDA).

Zhongshen’s response solutions:

- Start document pre-review 10 days in advance: Mr.He’s team will check the completeness of ISF filing information and certification documents in advance based on the product categories of Mianyang enterprises,to avoid delays caused by supplementary filing after the goods arrive at the port;
- Establish a US certification database: For certifications such as FDA and CPSIA,we have sorted out compliance checklists for common products from Mianyang.Enterprises only need to provide basic materials to complete certification docking quickly;
- Sync policy updates in real time: We push the latest document requirements of US Customs every month,such as the new "sustainable packaging filing" added in 2026,to help enterprises adjust document templates in advance.

### 2.US Customs Clearance Services – Solve ACE System and Anti-Dumping Duty Verification Issues

The **ACE (Automated Commercial Environment)** system of US Customs is the core platform for customs clearance.After the system was upgraded in 2026,the requirement for HS code matching accuracy for products has increased to 99%.Incorrect codes will directly trigger inspection.In addition,some mechanical and electrical products exported from Mianyang (such as photovoltaic modules) are still on the anti-dumping duty list,and detailed origin certificates and cost accounting materials are required,otherwise high tariffs will be imposed.

Mr.Kong,Head of the Customs Clearance Department at Zhongshen,introduces that they have established a "code pre-verification mechanism" for the US ACE system:

- Double check of HS codes: After the enterprise provides the preliminary code,the system will first match the latest US tariff schedule,and then manually review the product parameters to ensure 100% accuracy of the code;
- Special anti-dumping duty service: For photovoltaic enterprises in Mianyang,we assist in preparing origin certificates and supply chain traceability materials in advance.If they meet the exclusion conditions,we will also assist in applying for tariff reduction and exemption;
- Fast response to inspection: We have established direct connections with customs brokers at 12 major ports in the US.If inspection is triggered,supplementary materials can be submitted within 2 hours,and the average inspection time is reduced from the industry average of 5 days to 2 days.

### 3.Export Tax Refund Services – Resolve Pain Points in US Transaction Data Matching

After Mianyang enterprises export goods to the US,the tax refund process is often stuck due to "inconsistency between US Customs data and domestic declaration data".In 2026,China’s tax authorities require that tax refund applications be supported by documents such as customs clearance receipts of US importers and copies of bills of lading.If the materials are incomplete,the tax refund cycle will be extended from 15 days to more than 30 days.

Mr.Teng,Manager of the Finance and Taxation Department at Zhongshen,mentions that they improve the tax refund speed through "data synchronization + material pre-review":

- Real-time synchronization of US customs clearance data: We connect API interfaces with US customs brokers,and obtain customs clearance receipts and copies of bills of lading within 1 hour after the goods are cleared,which are directly synchronized to the domestic tax system;
- Pre-review of tax refund materials in advance: Before the enterprise submits the tax refund application,Mr.Teng’s team will check the consistency of invoices,contracts and customs clearance data for US transactions,to avoid rejection due to data mismatch;
- Customized tax refund cycles: For batch exports of Mianyang textile enterprises,we provide "batch-by-batch tax refund" services,shortening the average tax refund cycle to 12 days,3 days faster than the industry average.

### 4.Ocean Freight Logistics Services – Respond to Congestion at US West/East Coast Ports

In 2026,the congestion index of US West Coast ports (Los Angeles,Long Beach) remains around 1.2 (a congestion index >1 indicates congestion),while the space premium rate of US East Coast ports (New York,Savannah) reaches 15%-20% due to growing demand for supply chain transfer.If Mianyang enterprises choose conventional ocean freight,the delivery period may be delayed by 7-10 days.

| Port Type | Major Ports | 2026 Congestion Status | Zhongshen’s Response Measures |
| --- | --- | --- | --- |
| US West Coast Ports | Los Angeles,Long Beach | Congestion index 1.2,average berthing time 48 hours | 1.Reserve "emergency space": Sign long-term agreements with shipping companies to reserve 200 TEU of emergency space per month; 2.Prioritize "express routes": The time limit of US West express routes is 3 days faster than conventional routes |
| US East Coast Ports | New York,Savannah | Space premium 15%-20%,stable time limit but tight space | 1.Combined transportation: Part of the goods are transported by "sea freight + rail" (for US East inland points); 2.Lock space in advance: Lock space 15 days before cargo loading to avoid premium |

## How Zhongshen Improves Customs Clearance Efficiency and Tax Refund Speed for Mianyang Enterprises

Combined with 20 years of service experience,Zhongshen has summarized three efficiency improvement methods for Mianyang enterprises exporting to the US:

- "Pre-positioned" services: For example,for products of Mianyang mechanical and electrical enterprises,we check US certification requirements in advance during the production stage,to avoid temporary certificate supplementation before export;
- "Localized" docking: We have established a direct connection team with customs brokers in Los Angeles and New York,eliminating third-party transit during the customs clearance process,increasing information transmission speed by 40%;
- "Digital" management: We integrate document,customs clearance and tax refund data through the internal system,so enterprises can view the export progress in real time without repeated communication.

Last year,a textile enterprise in Mianyang exported goods to the US through Zhongshen.The originally feared CPSIA certification delay was avoided as we completed the pre-review 10 days in advance.Finally,the customs clearance time was 4 days faster than before,and the tax refund cycle was also shortened from 20 days to 11 days.

## Customized Services Adapt to the Different Needs of Mianyang Enterprises

The product categories of Mianyang enterprises exporting to the US vary greatly,so Zhongshen provides customized services: for example,for agricultural product enterprises,we add pre-inspection services of the US Department of Agriculture (USDA); for mechanical and electrical enterprises,we provide special consultation on tariff exclusion applications; for small,medium and micro enterprises,we provide a packaged service of "document + customs clearance + tax refund" to reduce operating costs.
