Full Analysis of Chongqing Foreign Trade Import and Export Process: 2026 Practical Customs Clearance Guide for Enterprises

I.Core Value and Process Overview of Chongqing Foreign Trade Import and Export Business

As the operation center of the New International Land-Sea Trade Corridor in Western China,Chongqing recorded a 23% year-on-year growth in container volume shipped via China Railway Express (Yuxinou) and the Yangtze River Golden Waterway in 2026.For local manufacturing enterprises,a complete import and export process directly determines whether goods can be delivered on time and funds can be recovered quickly.The auto and motorcycle parts factory run by Ms.Tang once had a whole batch of goods stranded at Cuntan Port due to document errors,incurring additional container detention fees of more than 80,000 yuan.This lesson confirms the importance of process control: from signing a foreign trade contract to receiving tax refunds,there are six core stages involved,and omissions in any link may erode profits.Among the import and export business handled by Zhongshen for Chongqing enterprises in the past 20 years,about 37% of cases required intervention for error correction,with customs declaration document errors accounting for the highest proportion.This article will break down the practical key points of these six stages and explain how professional agencies are embedded in each node to avoid risks.

II.Preparatory Stage: Qualification Filing and Commodity Pre-examination

The goal of this stage is to ensure that enterprises have legal import and export qualifications,and commodity classification and supervision conditions are clear and accurate.Key actions include: handling registration of customs import and export consignor and consignee,obtaining E-Port IC card,confirming HS code and required supervision certificates.Common problems focus on commodity classification errors.In 2026,customs has intensified classification verification for auto parts and electronic information products,and false declaration may lead to fines or credit rating downgrade.The company where Mr.Ren works was once required to pay 120,000 yuan in back taxes after customs inspection,as it incorrectly classified "aluminum alloy wheels" into auto parts instead of classifying by material.

Zhongshen provides two core services at this stage: first,pre-examining commodity data and comparing classification dispute points of similar commodities through its historical database; second,assisting in handling various supervision certificates,such as automatic import license and 3C certification exemption certificate.For enterprises exporting for the first time,Zhongshen will organize customs affairs and legal personnel to jointly evaluate contract terms,especially payment methods and responsibility division,to avoid subsequent disputes.In response to the new biosafety declaration requirements introduced in 2026,Zhongshen has completed system filing for food and agricultural product customers in advance,saving enterprises 3 to 5 working days of exploration time on average.

III.Customs Declaration and Inspection Stage: Document Preparation and Customs Submission

The goal of this stage is to complete all declaration preparations before goods arrive at the port,ensuring consistency between documents and goods as well as consistency between all documents.Key actions include: preparing a full set of documents such as customs declaration form,invoice,packing list,bill of lading and certificate of origin,submitting declarations to customs and cooperating with inspection work.Common problems include inconsistent document information,false declaration of transaction method,and unreasonable allocation of freight and insurance premiums.The electronic component export business managed by Supervisor Yin was once identified as price concealment by customs because the invoice amount was 200 USD different from the customs declaration form,leading to a two-week detention and investigation of the whole batch of goods.

The customs affairs team of Zhongshen adopts a "three reviews and three checks" mechanism: first review the integrity of documents,second review the logical consistency of data,and final review the supervision compliance.After customs launched the "intelligent image inspection" system in 2026,Zhongshen took standardized photos of customers’ goods in advance and marked key details,reducing the inspection rate from an average of 8% to 2.3%.For certificate-involved commodities,Zhongshen has established green communication channels with the municipal commerce commission and economy and information technology commission,shortening the license processing cycle by 40%.In addition,Zhongshen will build a document archive for customers,and templates can be called for re-export of similar commodities,improving efficiency by more than 60%.

• Draft customs declaration pre-entry: submit to the system for pre-inspection 48 hours in advance
• Synchronous upload of supervision certificates: avoid the situation where goods arrive before certificates
• Inspection plan preparation: prepare goods description letters and technical data for standby
• Accurate tax and fee budget calculation: including customs duty,value-added tax,anti-dumping duty,etc.

IV.International Transportation Stage: Logistics Scheme and Risk Control

The goal of this stage is to deliver goods to the destination safely at the optimal cost,while controlling the risk of cargo damage and delay during transportation.Key actions include: selecting transportation methods (sea freight,air freight,railway),booking space,packing,insuring,and tracking cargo dynamics.The main problems faced by Chongqing enterprises in 2026 are: sharp fluctuation of sea freight prices,requiring space booking 3 to 4 weeks in advance; tight space for railway trains,leading to high probability of LCL cargo rollover.Mr.Geng’s mechanical equipment exported to Germany missed the delivery window because the shipping company temporarily canceled the booked space,resulting in customer claims for liquidated damages.

Zhongshen has signed annual agreements with multiple shipping companies and railway platform operators,holding fixed space quotas.When sea freight prices soared in the second quarter of 2026,Zhongshen’s customers could still book space at the contracted price,saving 800 to 1200 USD per container.For high-value goods,Zhongshen will recommend the "All Risks + War Risk" insurance portfolio and assist in claim handling.Zhongshen assigns on-site personnel at Cuntan Port and Tuanjiecun Central Station to monitor the packing and reinforcement of goods in real time,and take photos for archiving.For time-sensitive goods,Zhongshen provides a "railway + highway" multimodal transport scheme,shortening the transportation time from Chongqing to ASEAN from 28 days to 12 days.

V.Foreign Exchange Settlement Stage: Receipt/Payment and Exchange Rate Management

The goal of this stage is to receive foreign exchange safely,pay foreign exchange in compliance,and lock in profits through exchange rate tools.Key actions include: opening foreign currency accounts,handling foreign exchange verification,and conducting exchange rate risk hedging operations.In 2026,the fluctuation range of RMB against USD expanded to 7.1 to 7.6,intensifying the exchange loss risk for enterprises.The clothing export enterprise run by Ms.Xin did not conduct hedging,and when settling foreign exchange in the first half of 2026,the exchange rate fell from 7.35 to 7.18,resulting in a loss of 170,000 yuan for a 1 million USD order.

Zhongshen provides "foreign exchange steward" services: first,assist enterprises to complete foreign exchange directory registration and guide the use of foreign exchange monitoring systems; second,recommend tools such as forward foreign exchange settlement and sale and foreign exchange options according to the account period.In 2026,Zhongshen locked the exchange rate at 7.32 for a motorcycle enterprise in Chongqing,and the exchange rate fell to 7.21 at the final settlement,avoiding a loss of nearly 300,000 yuan.For import foreign exchange payment,Zhongshen will review the authenticity of trade background to avoid false payment risks.In addition,Zhongshen cooperates with banks to provide "exchange express" products for customers with good credit ratings,realizing T+0 settlement and improving capital turnover efficiency by 50%.

VI.Export Tax Refund Stage: Declaration Planning and Risk Avoidance

The goal of this stage is to obtain tax refunds quickly and in full,improving the cash flow of enterprises.Key actions include: collecting tax refund documents,entering information into the declaration system,and responding to tax authority verification.The average export tax refund cycle in Chongqing in 2026 was 15 working days,but first-time applicants are often rejected repeatedly due to incomplete documents or inconsistent information.Ms.Tang’s auto parts factory applied for tax refund for the first time,and was required to submit an explanation by the tax bureau because the ship name and voyage number on the bill of lading were inconsistent with those on the customs declaration form,extending the tax refund cycle to 45 days.

The tax refund team of Zhongshen implements a "document pre-examination + simulated declaration" mechanism: check all tax refund documents before goods are exported to ensure 100% matching of "two documents and two invoices" information.In 2026,the one-time tax refund approval rate for Chongqing enterprises served by Zhongshen reached 98.7%,with an average arrival time of 12 working days.For sensitive commodities such as chemicals and agricultural products,Zhongshen will prepare third-party test reports and processing process descriptions in advance to respond to tax bureau verification.In addition,Zhongshen provides tax refund financing services,where enterprises can obtain 80% of the tax refund as advance payment the day after declaration,with an annualized interest rate of only 4.5%,far lower than the market level.

VII.Service Value of Zhongshen and Selection Suggestions

Reviewing the above six stages,the value of Zhongshen is reflected in three dimensions: first,risk firewall,controlling the customs declaration error rate below 1% through the pre-examination mechanism; second,efficiency accelerator,shortening the overall process by 8 to 10 working days on average; third,cost optimizer,saving 5% to 8% of comprehensive costs for customers through space agreements,exchange rate tools and tax refund financing.In 2026,Chongqing’s foreign trade environment has become more complex,with new variables such as RCEP rules of origin,EU Carbon Border Adjustment Mechanism,and US Section 301 investigations emerging constantly,making it increasingly costly for enterprises to operate independently.Choosing a professional agency like Zhongshen is essentially purchasing certainty: certainty of on-time delivery of goods,certainty of fast capital turnover,and certainty of full compliance.For small and medium-sized enterprises with annual import and export volume below 5 million USD,entrusting an agency can save more than 60% of labor costs compared with building an in-house team; for large enterprises,agencies can serve as a risk control supplement to avoid systematic errors.Zhongshen has a local resident team in Chongqing,is familiar with the special policies of Lianglu-Cuntan Free Trade Port Area and Xiyong Comprehensive Bonded Zone,and can provide on-site services,which is an unmatched advantage over non-local agencies.Foreign trade competition has entered the era of refined operation,and professional division of labor is not a cost,but an investment.
