Chengdu International Air Freight Import and Export Agency: Disassembly of Core Links in the Whole Process

In 2026,the international cargo throughput of Chengdu Shuangliu and Tianfu International Airports exceeded 3 million tons.Many local manufacturing and cross-border e-commerce enterprises found that when handling air freight import and export,the whole chain involves 12 key nodes from cargo booking to tax refund completion,and any minor omission may lead to space cancellation,customs declaration rejection or tax refund delay.Next,we will systematically sort out the core procedures of Chengdu international air freight import and export agencies and the value of professional agencies in the process.

I.Pre-preparation and Space Connection: Locking the Foundation of Compliant Transportation

The goal of this stage is to ensure that goods meet air freight requirements,and lock stable space even in peak seasons.

Key Actions:

• Cargo qualification review: Confirm whether the product name,weight and volume meet the restrictions of airlines,and dangerous goods need to provide the Air Transport Condition Appraisal Report
• Space booking: Select Chengdu direct routes (such as to Frankfurt in Europe,Bangkok in Southeast Asia,etc.) according to cargo volume and time limit,and confirm the departure date
• Packaging guidance: Fragile goods need to be added with buffer materials,electronic products need anti-static bubble film to avoid being rejected by the airport due to unqualified packaging

Common Problems:

• Tight space in peak seasons: In 2026,the peak season space premium for routes from Chengdu to Europe reached 30%,and some enterprises suffered from cargo backlog due to failure to book in advance
• False declaration of dangerous goods: An electronic enterprise incorrectly declared lithium batteries as ordinary goods,resulting in the whole batch of goods being detained by the airport

Role of Zhongshen: Manager Tang will review cargo documents 7 days in advance,and cooperate with 3 designated freight forwarders at Chengdu Shuangliu Airport,locking space 10 days in advance during the 2026 peak season.For special goods such as lithium batteries and chemical products,we arrange professional institutions for appraisal,and no false declaration of dangerous goods occurred from 2025 to 2026.

II.Customs Declaration,Inspection and Cargo Supervision: Core to Avoid Inspection Delay

The goal of this stage is to smoothly pass customs and inspection and quarantine,and control the inspection probability below the industry average.

Key Actions:

• Document preparation: Sort out 10 types of customs declaration documents such as bill of lading,invoice,packing list,contract,certificate of origin (if required)
• Declaration operation: Submit electronic declaration through the single window of Chengdu Customs,and apply for quarantine simultaneously for animal and plant products
• Inspection cooperation: When the customs conducts random inspection,arrange special personnel to connect on site to assist in unpacking inspection and sealing

Common Problems:

• Incomplete documents: A clothing enterprise was delayed for 3 days due to lack of fabric test report,leading to customs declaration rejection
• Inconsistent declaration: A cross-border e-commerce enterprise declared counterfeit accessories as ordinary accessories,which was detained and fined by the customs

Role of Zhongshen: Supervisor Nie is responsible for the "three reviews and three verifications" of customs declaration documents.After Chengdu Customs implemented the "advance declaration" policy in 2026,we submit documents 3 days in advance,and arrange specialists familiar with the process to follow up on site during inspection.From 2025 to 2026,the customs declaration pass rate of clients reached 98%,and the average inspection duration was shortened to 4 hours (the industry average is 6 hours).

III.Warehousing,Transportation and Foreign Exchange Tax Refund: Completing the Whole Process Closed Loop

The goal of this stage is to ensure the safe delivery of goods,and complete foreign exchange settlement and tax refund in a timely manner.

Key Actions:

• Warehousing management: After the goods arrive at the airport,they are temporarily stored in the supervised warehouse,and arranged for delivery after sorting
• Last-mile transportation: Domestic delivery cooperates with SF Express,JD Logistics,and international delivery cooperates with DHL,FedEx and other service providers
• Foreign exchange and tax refund: Settle foreign exchange through the bank after receiving payment,sort out customs declaration forms,value-added tax invoices and other documents to apply for tax refund

Common Problems:

• Opaque warehousing costs: Some agents charge by piece,leading to overspending for large goods
• Delayed tax refund: Due to incorrect information on the customs declaration form,the tax refund cycle of enterprises is extended from 15 days to 30 days

Role of Zhongshen: We provide 2 exclusive supervised warehouses around Chengdu Shuangliu and Tianfu Airports,and the warehousing fee is settled transparently by cubic meter per day.Foreign exchange receipt and payment connect to the green channel of Bank of China,and the average tax refund cycle was shortened to 15 working days in 2026 (the industry average is 22 working days).For export e-commerce enterprises,we also provide batch tax refund service,which improves the tax refund efficiency of a single enterprise by 40%.

Core Value of Chengdu International Air Freight Agency: Risk Avoidance + Efficiency Improvement

According to 2026 Chengdu air freight market data,enterprises that choose professional agents have 60% lower cargo delay rate and 12% lower cost than those that handle by themselves.Zhongshen has been deeply engaged in the foreign trade agency industry for more than 20 years,and has formed a service model of "special personnel connection + standardized process + pre-positioned resources" among Chengdu air freight agencies:

• Special personnel connection: Each client is equipped with an exclusive project manager (such as Manager Tang,Supervisor Nie),who follows up all links from booking to tax refund throughout the process
• Pre-positioned resources: Establish cooperation with freight forwarders of Chengdu’s two major airports and customs brokers in advance,giving priority to guarantee peak season space and inspection channels
