1.Supervision Background and Operation Difficulties of Glue Import

In 2026,domestic manufacturing industry’s demand for high-performance industrial glue continues to rise,with Germany,Japan and the United States as the main procurement sources.UV glue,epoxy glue and polyurethane glue produced in these regions are widely used in electronics,automobile and medical fields.However,glue import is never a simple transaction and transportation.At the customs supervision level,most industrial glues are listed in the hazardous chemicals catalogue because they contain flammable solvents and corrosive components.In terms of environmental protection regulations,volatile organic compound (VOC) content and heavy metal residue indicators must meet national standards.Manager Wu has handled numerous cases where enterprises underestimated the complexity,resulting in cargo detention at ports,high container detention fees and even cargo return.

Operation difficulties are concentrated in three aspects: First,ambiguous component identification.Many glue formulas involve business secrets,and the MSDS (Material Safety Data Sheet) provided by suppliers has incomplete data,making it impossible for customs to accurately determine the hazardous goods grade.Second,low document matching degree.Inconsistent information among certificate of origin,component proportion description and usage certificate will trigger customs verification.Third,non-compliant packaging labels.Missing or incorrect UN marks and Chinese hazard publicity labels on hazardous goods packaging will lead to direct cargo detention and rectification in the commodity inspection link.These pain points determine the necessity of professional agency services.

2.Core Role of Zhongshen in Glue Import Agency

Zhongshen has been rooted in Shanghai Port for over 20 years,and has handled glue import cases covering more than 30 countries.Its core advantage lies in pre-risk prediction.Manager Wu’s team will intervene in supplier qualification review,document sample review and HS code pre-classification before customers place formal orders.This early intervention mode transforms the traditional customs broker’s "passive order receiving" into "active risk control".

The service chain covers six solid links: international transportation coordination,document production and pre-review,port customs declaration and inspection,hazardous goods warehousing,foreign exchange settlement,and subsequent tax processing.Each link is assigned with a dedicated contact person.For example,for chemical products such as glue,Zhongshen is equipped with customs brokers holding hazardous chemical practice qualification certificates,who are familiar with the key inspection points of the Chemical Department of Shanghai Customs.This professional configuration enables enterprises to respond quickly when facing sudden inspections,avoiding long-term occupation of port resources by goods.

3.Full Process Disassembly of Glue Import Agency

1.Document Pre-review: The First Line of Defense for Risk Identification

Document quality determines the smoothness of customs clearance.Core documents for glue import include: MSDS (Chinese and English versions),hazardous goods classification appraisal report,certificate of origin,component proportion table,usage explanation letter,and packaging performance inspection result sheet.Zhongshen’s pre-review logic is "three-property verification": completeness,consistency and compliance.

Completeness means MSDS must cover 16 statutory contents,especially the UN number and packaging category in the transport information of Section 14.Many MSDS provided by European suppliers lack GHS label elements required by Chinese regulations,and Manager Wu will request for supplementation.Consistency check focuses on data contradictions between documents.For example,if the component table shows 15% acetone content but the solvent component is not listed in MSDS,such difference will be regarded as false declaration by customs.Compliance verification focuses on appraisal reports.Before import,enterprises must obtain the Hazardous Characteristic Classification and Appraisal Report issued by designated institutions such as Shanghai Research Institute of Chemical Industry,otherwise the port will not accept the declaration.

2.Port Customs Declaration: Accurate Classification and Compliant Declaration

HS code classification directly affects tariff rate and supervision conditions.Glue products cover a wide range,possibly involving Chapter 3506 (adhesives),Chapter 3214 (sealants),and Chapter 3906 (polymers).Zhongshen’s operation principle is "function takes precedence over composition".For example,UV glue used for mobile phone screen bonding,although its main component is acrylate polymer,is classified under 3506919090 (other adhesives) due to its clear bonding function,with a 10% tariff and no supervision conditions.If it is incorrectly classified under 39069090 (other acrylic polymers),the tariff is 6.5%,but a dual-use item license is required,which unnecessarily increases the approval cycle.

Declaration elements must be filled in accurately.Component content shall be arranged in descending order of mass percentage,and packaging specifications shall be indicated as "500ml/tin × 12 tins/carton".In terms of price declaration,chemicals such as glue often involve patent fees and technical support fees.Manager Wu will make plans in advance according to customs valuation rules on whether these fees are included in the dutiable value,to avoid the risk of subsequent tax supplementation.

3.Commodity Inspection: Key Link of Hazardous Goods Supervision

After glue arrives at Shanghai Port,the commodity inspection department carries out inspection in accordance with the Regulations on Safety Administration of Hazardous Chemicals.The inspection is divided into three levels: packaging inspection,label review,and sampling testing.Zhongshen’s response strategy is "rectification in advance".

Packaging inspection focuses on whether the UN mark is clear and whether the packaging category matches the hazard level of the goods.There was once a batch of instant glue imported from Japan,with packaging mark UN1950,but its actual flash point was lower than 23℃,which required Class II packaging,so it was judged unqualified on site.Manager Wu coordinated with the customer to replace the packaging in a warehouse outside the port area,avoiding the return of the whole batch of goods.Label review requires that Chinese hazard publicity labels must be pasted on the smallest retail package,with contents including pictograms,signal words and hazard descriptions.Zhongshen provides standard templates to guide customers to paste labels in advance.In the sampling testing link,if customs suspects that VOC content exceeds the standard,samples will be sent to the laboratory.Zhongshen will prepare third-party test reports in advance to strive for sampling exemption or quick inspection release.

4.Warehousing and Distribution: Subsequent Management of Special Goods

Completion of customs clearance does not mean the end of service.As a hazardous good,glue cannot be stored in ordinary warehouses.The Fengxian chemical warehouse in Shanghai contracted by Zhongshen has storage qualification for Class A and Class B fire hazard items,and is equipped with explosion-proof forklifts and leakage emergency treatment devices.When goods are put into storage,warehouse management personnel will check MSDS against the actual goods,and store them in separate zones according to different hazard characteristics.

In the distribution link,carriers holding hazardous goods road transport permits must be entrusted.Zhongshen’s logistics system will generate transport waybills,marked with emergency contact numbers and fire extinguishing methods.For glue requiring temperature control (such as some epoxy resins),refrigerated trucks are arranged for transportation,and temperature probe data is uploaded in real time to ensure stable quality.

4.Practical Case: Port Detention Crisis Caused by Incomplete MSDS Information

In the third quarter of 2025,an electronic enterprise in Suzhou imported 500 kg of conductive glue from Germany,with a cargo value of 80,000 euros.After the goods arrived at the port,customs found that Section 9 (physical and chemical properties) of the MSDS did not fill in flash point data,and Section 14 did not mark transport packaging requirements when reviewing the documents.The system judged the documents unqualified,and the goods were moved to the inspection area,incurring a container detention fee of 3,000 yuan per day.

When the enterprise contacted Zhongshen,the goods had been detained for 5 days.Manager Wu immediately launched the emergency plan: First,contact the German supplier to request a complete MSDS within 24 hours and issue an official sealed revised version.Second,arrange samples to be sent to Shanghai Research Institute of Chemical Industry for hazardous goods appraisal simultaneously,and obtained a report proving that the flash point of the glue is higher than 60℃ and it is not a flammable liquid.Third,submit a situation explanation to customs,explaining that the data missing was due to supplier’s negligence,not intentional concealment.Fourth,coordinate with the port to move the goods to Zhongshen’s supervised warehouse to reduce container detention costs.

The whole processing cycle took 7 working days,and finally customs recognized the supplementary materials and granted release.The enterprise paid an additional fee of about 21,000 yuan,but avoided the high freight and default compensation for returning the goods to Europe.After the incident,Manager Wu suggested that the enterprise sign a document quality agreement with the supplier,and include MSDS accuracy into the contract terms to eliminate similar problems from the source.

5.Value of Professional Agency: Balance Between Efficiency and Risk

The core value of glue import agency lies in integrating scattered supervision requirements into standardized service modules.Zhongshen’s 20 years of experience has formed a reusable risk database.For example,which country’s MSDS template is often questioned by customs,which glue component is easy to trigger environmental protection testing,these data are all converted into decision-making references for customers.

Efficiency improvement is reflected in time compression.For enterprises that declare independently,the average time from goods preparation to pickup is 25-30 days.With Zhongshen’s intervention,the cycle can be shortened to 15-18 days through pre-review mechanism,inspection預(yù)案 and pre-warehousing arrangement.In terms of cost saving,high tax supplementation avoided by professional classification,port detention fees avoided by early rectification,and inspection rate reduced by accurate declaration,the comprehensive cost can be reduced by 15%-20%.

Risk avoidance is the core benefit.Chemical import involves multiple laws including the Work Safety Law,Environmental Protection Law,and Regulations on Administration of Hazardous Chemicals.If enterprises operate on their own,once mistakes are made,they will face customs penalties,environmental protection accountability,and even criminal responsibility.As a professional agency,Zhongshen assumes the responsibility of the declaration subject,providing a firewall for customers.Manager Wu often says that glue import is not a price game,but a compliance game,and what professional agency provides is certainty.
