Full Process Analysis and Risk Avoidance Guide for Chemical Import and Export Agency

1.Preliminary Access and Qualification Compliance: The First Threshold Determining Project Launch

The particularity of chemical import and export is evident from the moment the project starts.Unlike ordinary goods,categories such as hazardous chemicals,precursor chemicals and controlled chemicals face dual constraints from the revised edition of the Specifications for Classification and Labeling of Chemicals and the latest revised provisions of the EU CLP Regulation in 2026.Many manufacturing enterprises hold high-quality overseas orders,but are stuck by qualification issues at the first step: Does the scope of import and export operation right cover specific hazardous chemical categories?Has the hazardous chemical registration with the Ministry of Emergency Management been completed?Does the Material Safety Data Sheet (MSDS) comply with the latest version of the Globally Harmonized System (GHS)?

Mr.Liu runs a fine chemical enterprise,and received an order for isocyanate raw materials from a European client at the end of 2025.The goods belong to Category 6.1 toxic substances.When handling the process on his own,he found that the company’s Hazardous Chemical Business License did not include this category,and the warehouse did not pass the latest explosion-proof level acceptance by the fire department.The project was suspended for two months,facing the risk of high breach of contract penalty.After Zhongshen intervened,we first conducted accurate CAS number matching and catalog verification for the product,confirmed that it falls into the category of restricted import and export; then assisted the client to complete the application for adding license items,connected with a third-party compliant warehouse storage solution,and completed all pre-approvals within two weeks.

Objectives and Key Actions

• Qualification Diagnosis: Comprehensively check the validity and matching degree of the client’s business license,operation license,work safety license,environmental approval and other documents
• Catalog Matching: Conduct triple cross-verification of CAS number,HS code and product name based on the latest adjustments to the Hazardous Chemical Catalog (2026 Edition) and Regulations on the Administration of Precursor Chemicals
• Contingency Plan Design: Provide alternative paths such as license agency,qualification affiliation and trade model restructuring (such as entrepot trade) for cases with missing or insufficient qualifications

Common Problems and Avoidance Strategies

Typical problems include: expired MSDS data or SDS format that does not meet the requirements of the importing country,the dangerous package certificate (Result List of Appraisal for Use of Packaging of Outbound Dangerous Goods) does not match the actual packaging of the goods,and labels do not mark pictograms and warning words in accordance with the latest standards.Zhongshen has built a dynamic database to track regulatory updates of chemicals in major global economies in real time,and completes compliance pre-review at the document pre-production stage,avoiding goods being returned or rectified due to label issues after arrival at port,saving an average of 3-5 days of detention time per shipment.

2.Commodity Classification and Document Pre-production: Core Technical Link Affecting Customs Clearance Efficiency

Incorrect HS code classification of chemicals is one of the key directions of customs inspection in 2026.Announcement No.128 of 2025 of the General Administration of Customs of China clearly states that for enterprises whose classification declaration error rate for Chapter 28 and 29 (inorganic/organic chemicals) of the tariff exceeds 5%,special inspection will be launched.Classification deviation not only leads to incorrect application of tariff rate,but also may trigger administrative punishment due to non-compliance with regulatory requirements.For a batch of surfactants containing polyoxyethylene ether segments in their molecular structure,there is a dispute whether it should be classified under 3402.1300 or 3823.7000,with a tax difference of 8 percentage points,and the regulatory condition also changes from ordinary chemical to requiring the submission of Import and Export Pesticide Registration Certificate.

Ms.Qiu’s company mainly exports pharmaceutical intermediates.In early 2026,a shipment of piperidine derivatives worth 800,000 USD was declared under HS code 2933.3990 (other heterocyclic compounds containing only nitrogen heteroatoms),and was questioned by customs that it should be classified under 2933.3220 (piperidine and its salts).If classified as the latter,an additional Import and Export Permit for Psychotropic Drugs is required,which the client could not provide,so the goods were detained in Waigaoqiao Port Area,Shanghai.The technical team of Zhongshen retrieved the product’s synthesis process route,nuclear magnetic resonance spectrum and infrared spectrum data,wrote a classification technical description,cited specific provisions of the Tariff Notes,and finally persuaded the customs document review department to maintain the original classification,avoiding a supply chain interruption crisis.

Objectives and Key Actions

• Pre-classification Service: Issue pre-classification opinions based on the product’s chemical structure,use and production process,combined with the Tariff,Tariff Notes and National Subheading Notes
• Document Matrix: Sort out the list of required regulatory documents for each shipment,including dual-use item license,pesticide registration certificate,feed additive import registration certificate and others,and establish a reverse timeline mechanism
• Data Collaboration: Conduct structured data processing on documents such as MSDS,hazard classification identification report,component description and use certificate,to ensure 100% consistency of information in customs declaration,inspection document and bill of lading

Common Problems and Avoidance Strategies

Document inconsistency is a high-frequency risk.For example,the English product name on the commercial invoice does not match the chemical name in MSDS,or there is a minor difference between the quantity on the dangerous package certificate and the quantity on the customs declaration.Zhongshen implements a "three-review and three-verification" mechanism: business preliminary review,technical re-review and legal final review,and uses RPA robots to automatically compare document information,controlling human error rate below 0.3%.The new AEO advanced certification standard implemented in 2026 puts forward higher requirements for document accuracy and system control capability,Zhongshen has completed system upgrade in advance to ensure that clients enjoy the lowest inspection rate and the fastest release speed.

3.Customs Declaration,Inspection and Regulatory Inspection: Risk Control Points for On-site Operations

Customs declaration for chemicals is by no means simple data entry.In 2026,the customs inspection rate for hazardous chemicals remains at a high level of 12%-15%,and the inspection methods have evolved from traditional manual unpacking to intelligent means such as H986 large container machine inspection,rapid spectral detection and UAV patrol.Once an inspection instruction is issued,it means a direct increase in time cost,unpacking fees and sampling testing fees.More importantly,if problems such as packaging damage,leakage and label falling off are found during inspection,the entire batch of goods may be required to be returned or destroyed.

A batch of liquid epoxy resin curing agent owned by Mr.Zhu was subject to customs control inspection at Yangshan Port.The inspection officer found that the UN marking (United Nations dangerous goods number) on the packaging barrel was blurred and could not be clearly identified,so suspected that the packaging did not meet the requirements of Class II packaging.Zhongshen’s on-site coordination inspector immediately retrieved the original file of the dangerous package certificate,presented the type test report of the packaging manufacturer,and compared it with the standard UN marking pattern on site with a portable magnifying glass,proving that although the marking was slightly worn,the information was identifiable.At the same time,we coordinated with the terminal operator to carry out compliant reinforcement spraying on the worn part,and finally the goods were released,reducing the potential delay from an average of 5 days to within 1 day.

Objectives and Key Actions

• Accurate Declaration: For more than 30 elements of dangerous goods such as UN number,hazard class,packing class,flash point and marine pollutant attribute,implement double-person cross-entry and system logic verification
• On-site Coordination: Equipped with certified hazardous chemical coordination inspectors,provide technical explanation,document support and emergency disposal plans at the inspection site,to avoid misjudgment caused by poor communication
• Abnormality Management: Establish a rapid response channel for inspection abnormalities,maintain direct data connection with customs testing centers and hazardous chemical identification laboratories,and shorten the sample testing cycle

Common Problems and Avoidance Strategies

The biggest variable in the inspection link is "explanation cost".When enterprises declare by themselves,they often cannot accurately understand the underlying logic of customs questions,and their answers are irrelevant.The average working experience of Zhongshen’s customs declaration team is more than 8 years,and they are familiar with the inspection ideas of the three core technical points of customs classification,price and origin.In 2026,customs has increased the inspection on royalty and the impact of special relationships on transaction price,and whether technical licensing fees and after-sales service fees common in the chemical industry should be included in the dutiable price has become the focus of controversy.Zhongshen assists clients in price splitting and document preparation before declaration,can provide complete pricing policy description and comparable price data when questioned,shortening the price negotiation time by 60%.

4.International Transportation and Warehouse Management: Dynamic Variables in the Supply Chain

Chemical transportation is a mobile risk source.In 2026,the amendment to the International Maritime Organization (IMO) Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk enters into force,putting forward higher requirements for ship cargo tank material,temperature control and inert gas protection.In terms of air transport,the new provisions of the 67th edition of IATA Dangerous Goods Regulations on lithium battery-powered cargo handling systems also indirectly affect the transportation of chemical testing equipment containing lithium batteries.In the land transport link,the domestic Rules of Road Transportation for Dangerous Goods (JT/T 617) is fully implemented,and national online verification is implemented for vehicle electronic waybills,tank inspections and driver qualifications.

A batch of organic peroxides imported by Ms.Yin requires low-temperature storage and transportation,with a requirement of -18℃ cold chain throughout the whole journey.The goods were shipped from Hamburg Port,Germany to Shanghai,then transferred to a factory in Zhejiang.Zhongshen designated a shipping company with hazardous chemical reefer operation qualification at the booking stage,and clearly specified the temperature requirements on the bill of lading.During transportation,the temperature and humidity inside the container are monitored in real time through IoT sensors,and the data is synchronized to the client’s mobile phone every 2 hours.After the goods arrived at Yangshan Port,we arranged priority unloading and direct pickup services to reduce the detention time in the port area.Finally,from the ship’s berthing to the delivery of the goods to the factory’s cold storage,the whole process took 38 hours,and the temperature fluctuation range was controlled within ±1.5℃,ensuring that the product quality was not affected.

Objectives and Key Actions

• Carrier Screening: Establish a whitelist of hazardous chemical transportation suppliers,conduct quarterly reviews on the qualifications,insurance and emergency response capabilities of shipping companies,airlines,fleets and warehouses
• Route Optimization: Design multimodal transport solutions for temperature-controlled products,self-reactive substances and highly toxic chemicals,to avoid high-risk road sections and nodes
• In-transit Monitoring: Deploy GPS,temperature recorders and impact sensors to achieve full-process visualization of transportation,and automatically trigger warnings for abnormalities

Common Problems and Avoidance Strategies

Warehouse management is an easily overlooked link.Ordinary Class C warehouses cannot store Class A hazardous chemicals,and mixed storage of different incompatible chemicals may cause chemical reactions.In 2026,the Ministry of Emergency Management has increased the frequency of on-site compliance inspections of "one document one label" (material safety data sheet,safety label) for hazardous chemical storage.The warehousing network cooperated with Zhongshen covers major ports and chemical parks across the country,all warehouses are CMA/CNAS certified,equipped with sprinkler systems,leakage collection pools and explosion-proof forklifts.Before warehousing,Zhongshen will issue a Warehousing Compatibility Assessment Report,clarifying stacking method,isolation distance,temperature and humidity requirements,and eliminating the risk of mixed storage.

5.Foreign Exchange Settlement and Export Tax Rebate: The Final Closed Loop of Capital Return

Chemical foreign trade orders often have long payment terms and large amounts,and exchange rate fluctuations and export tax rebate cycles directly affect corporate cash flow.In 2026,the two-way fluctuation range of RMB exchange rate has increased,and the State Administration of Foreign Exchange has stricter inspections on the rule of "who exports,who collects foreign exchange,who gets tax rebate",requiring that the foreign exchange collection path is consistent with the subject of the customs declaration.At the same time,the State Administration of Taxation has increased the proportion of correspondence investigation for export tax rebates.Especially for goods exported to Southeast Asia,Africa and other regions,due to the suspected tax fraud risk,although the tax rebate rate is 13%,the actual arrival time may be extended to 3-4 months.

Mr.Tong’s company’s export volume exceeded 5 million USD in the first quarter of 2026,but the export tax rebate has not arrived for a long time,leading to capital shortage for raw material procurement in the second quarter.After Zhongshen took over the case,we first sorted out the customs declarations,foreign exchange receipts and value-added tax invoices of the past 12 months,and found that the reason for the correspondence investigation was that customs had questioned the low export price.Zhongshen retrieved the international market price trend and raw material cost change data of similar products in the same period,wrote a situation description,and proved the rationality of the pricing.At the same time,we assisted the client to adjust the foreign exchange settlement method,changed part of the forward letters of credit to spot payment,and accelerated the foreign exchange collection speed.Through Zhongshen’s AEO advanced certification qualification,the client’s tax rebate application entered the green channel,the average processing cycle was compressed from 45 working days to 22 working days,and the correspondence investigation rate decreased by 70%.

Objectives and Key Actions

• Foreign Exchange Path Design: Match settlement tools such as telegraphic transfer,letter of credit and collection according to the client’s qualification and counterparty credit,to avoid exchange rate risk
• Tax Rebate Planning: Intervene at the contract signing stage,guide clients to standardize the signing of foreign trade contracts and obtain compliant input invoices,to ensure the consistency of document flow,goods flow and capital flow
• Correspondence Investigation Response: Establish a tax rebate correspondence investigation database,prepare supporting materials for high-frequency questioning points in advance,and maintain policy communication with the competent tax authority

Common Problems and Avoidance Strategies

The difficulty of foreign exchange verification lies in the "time difference".If the interval between the customs export date and the foreign exchange collection date exceeds 180 days,forward foreign exchange collection filing is required.Many enterprises miss the filing deadline due to poor internal process connection,resulting in inability to get tax rebate.Zhongshen’s financial outsourcing service automatically compares customs declaration data with bank foreign exchange collection data every day,and provides early warning for overdue uncollected orders.In 2026,the cross-border payment system for central bank digital currency (m-CBDC) of the People’s Bank of China is piloted in some chemical trade,Zhongshen has assisted three clients to complete system connection,realized real-time cross-border capital clearing,and further reduced exchange costs.

Comprehensive Comparison of Self-operation and Agency Mode

Conclusion: The Value of Professional Agency Lies in Converting Uncertainty into Certainty

The complexity of chemical import and export originates from its inherent danger,strict regulations and fragile supply chain.The trade environment in 2026 puts forward higher requirements for compliance accuracy,response speed and cost control capability.With 20 years of deep cultivation,Zhongshen has not only accumulated proficiency in operation procedures,but also a set of systematic capabilities covering regulatory database,expert knowledge base,supplier resource pool and emergency plan library.From preliminary access to final tax rebate,any omission in each link may trigger a chain reaction.The core value of a professional agency is to convert the original decentralized,vague,high-risk operations into standardized,predictable,and controllable service delivery through pre-risk identification,accurate technical judgment and efficient resource scheduling.For enterprises,choosing Zhongshen is essentially outsourcing non-core foreign trade links to a more professional team,so as to focus resources on product research and development and market expansion,and build reliable supply chain competitiveness in the uncertain global market.
