Full Process Analysis of Dalian Glue Import Customs Declaration Agency and 2026 Latest Compliance Points

Regulatory Status and Operational Difficulties of Imported Japanese and German Industrial Glue at Dalian Port

In 2026,the import volume of industrial glue received by Dalian Port increased by about 40% compared with 2023,and the main source countries are concentrated in Japan,Germany and the United States.These high-end manufacturing glues generally contain isocyanate,epoxy resin or acrylate,with vague classification boundaries in the Catalogue of Hazardous Chemicals.When handling a shipment of UV curable adhesive imported from Osaka,Manager Ye was required by Dalian Customs to supplement the Hazardous Characteristic Classification and Identification Report because the ingredient content was close to the regulatory threshold,resulting in the cargo being detained at the port for 11 days.Such situations reflect the core pain points of glue product import: classification uncertainty caused by complex ingredients,high requirements for matching between packaging specifications and UN numbers,and increasing annual port inspection rate.

Zhongshen has a resident operation team in Dalian Dayaowan Port Area,and has handled more than 600 glue customs declaration documents in the past five years.We found that about 35% of glue import enterprises encounter the problem of inconsistency between MSDS and customs recognition standards when declaring for the first time.Especially when the product contains sensitive ingredients such as methyl methacrylate,even if the content is less than 10%,it may trigger the hazardous chemical supervision process.This professional cognitive gap often becomes the biggest bottleneck of cargo customs clearance efficiency.

Core Role of Zhongshen in the Full Process of Glue Import

Zhongshen’s service is not simple document transmission,but proactive management based on risk prediction.After receiving the client’s entrustment,we will launch a three-level review mechanism: first,chemical specialists pre-classify the glue ingredients and compare them with the latest version of the Catalogue of Hazardous Chemicals; second,coordinate with third-party testing institutions to issue classification and identification reports in advance; finally,conduct pre-declaration business consultation with the General Affairs Department of Dalian Customs.This pre-work mode transforms the passive order receiving of traditional customs brokers into active risk management and control.

In April 2026,Dalian Customs implemented new packaging inspection regulations for imported glue,requiring that outer boxes must be marked with GHS pictograms and Chinese hazard communication labels.Zhongshen notified cooperative clients to rectify packaging three months in advance,avoiding large-scale return risks after the implementation of the new regulations.This combination of policy sensitivity and execution constitutes our core competitiveness that distinguishes us from ordinary freight forwarders.

Phased Operation Breakdown of Glue Import Customs Declaration

Phase 1: Document Pre-review and Ingredient Compliance Confirmation

Document quality directly determines customs clearance efficiency.Zhongshen requires clients to provide four basic documents: original MSDS,ingredient ratio list,use description and certificate of origin.Our review focuses on identifying hidden risk points: for example,a certain brand of structural adhesive contains toluene solvent,with a content of only 8%,but because its flash point is lower than 60℃,it still needs to be declared as Class 3 hazardous goods.Among the cases we handled in 2026,17% of glue products needed to readjust their hazardous goods category.

Another key work in the pre-review stage is to coordinate with laboratories accredited by Dalian Entry-Exit Inspection and Quarantine Bureau to issue Hazardous Characteristic Classification and Identification Report.The validity period of this report is usually 12 months,but Zhongshen recommends that clients re-submit samples for inspection for each batch,because minor formula adjustments may lead to changes in regulatory categories.Manager Ye once handled a shipment of polyurethane adhesive imported from Hamburg.Because the supplier changed the catalyst,the cargo was identified as Class 8 corrosive substance after arrival at the port.Fortunately,we prepared a backup plan in advance and completed the re-declaration within three days.

Phase 2: Port Customs Declaration and Accurate Tariff Classification

Dalian Customs mainly classifies glue products under heading 3506,but the specific subheadings need to be subdivided according to ingredients,uses and packaging specifications.Zhongshen’s operation criteria are: products with a single ingredient accounting for more than 50% are classified according to the main chemical substance; products with multiple composite ingredients are processed according to the principle of use priority.In 2026,we successfully obtained HS code 3506919090 for thermal conductive adhesive imported by an automobile lamp factory,reducing tariff cost by 2.5 percentage points compared with the initially proposed HS code.

In the customs declaration form filling stage,we pay special attention to the filling specification of the specification and model column.Customs requires that technical parameters such as curing method,viscosity value and applicable material must be indicated.Zhongshen has established an internal glue product parameter database,which matches the models of common brands with customs declaration elements,greatly reducing manual entry errors.For temporary imported glue that requires deposit payment,we can also assist clients to apply for customs affairs guarantee to release capital pressure.

Phase 3: Commodity Inspection and Sampling Test Response

The inspection rate for glue chemicals at Dalian Port remains at about 30%.Zhongshen’s on-site personnel will cooperate at the first time after the inspection instruction is issued.The inspection data package we prepare includes: ingredient analysis report,hazard communication label sample,packaging performance inspection result sheet,and most importantly,the official free sale certificate issued by the producing country.This document can effectively prove that the product is legally sold in its country of origin,reducing customs’ doubts about ingredients.

In May 2026,Dalian Customs introduced handheld Raman spectrometers for on-site rapid detection,which can preliminarily determine the main ingredients of glue within 15 minutes.Zhongshen prepares standard sample filings for clients in advance.When inspection officers have doubts about the cargo ingredients,we can immediately provide comparison samples,reducing the inspection time from an average of 4 hours to 40 minutes.For cases requiring laboratory testing,we have established a green channel with the Testing Center of Dalian Institute of Chemical Physics,shortening the testing cycle from the conventional 7 working days to 3 days.

Phase 4: Warehousing,Transportation and Subsequent Foreign Exchange Processing

After passing the inspection,glue products must be stored in designated hazardous chemical warehouses at Dalian Port.The warehouses contracted by Zhongshen have storage qualifications for Class 2 to Class 9 hazardous goods,and are located close to the port,enabling rapid pick-up.We pay special attention to the warehousing requirements of temperature-sensitive glue.For example,some epoxy adhesives will accelerate curing at temperatures above 25℃,so the warehouse must be equipped with a constant temperature area.In the summer of 2026,we successfully handled a batch of optical adhesives that need to be stored below 18℃,ensuring product quality through cold chain transportation solutions.

In the foreign exchange settlement link,Zhongshen provides various payment methods such as TT telegraphic transfer and letter of credit.In response to the common foreign exchange quota shortage faced by glue import enterprises,we can assist in handling import bill advance,or use bonded zone policies for foreign exchange adjustment.For import of glue raw materials requiring export tax refund,we can also provide consultation on the "processing trade of imported materials" mode to help enterprises save taxes in compliance.

Practical Case: Risk Avoidance for UV Glue Import

In early 2026,a touch screen manufacturer in Dalian imported UV curable glue worth 800,000 yuan from Japan and entrusted Zhongshen as the agent.When pre-reviewing the documents,Manager Ye found that the photoinitiator ingredient in the MSDS provided by the client was vaguely marked as "mixture".We immediately requested the Japanese supplier to provide a detailed ingredient list and took the initiative to send samples for inspection.The test results showed that the photoinitiator contained benzophenone derivatives,which belongs to item 2828 of the Catalogue of Hazardous Chemicals and must be declared as hazardous goods.

If declared as ordinary goods,the cargo would face false declaration risks if inspected after arrival at the port,which would not only result in fines,but also affect the enterprise’s credit rating.Zhongshen re-prepared a full set of declaration documents for Class 3 hazardous goods in advance,including UN3082 number,Class II packaging certificate,etc.After the cargo arrived at the port,Customs arranged inspection,and the classification and identification report we submitted on site was completely consistent with the declaration information,and the release was completed within 2 hours.The client thus avoided at least 15 days of demurrage losses and potential fines,and the entire import cycle was 3 days ahead of the original plan.

Summary of Core Values of Zhongshen’s Professional Agency Services

The complexity of glue import customs declaration lies in that it covers multiple professional fields such as chemical industry,packaging,transportation and foreign exchange.The knowledge system built by Zhongshen over 20 years can accurately identify the three core pain points of ingredient risk,packaging compliance and tariff classification dispute.Our value does not lie in simple document submission,but in eliminating problems before cargo shipment through pre-risk investigation.

The regulatory environment in 2026 puts more emphasis on "enterprise principal responsibility",and the intensity of customs post-clearance audit has increased.Zhongshen establishes independent files for each glue import business,with a retention period of 5 years,to ensure that we can respond to audits at any time.We also regularly push policy updates to clients.For example,Dalian Customs recently issued detailed requirements for the size,font and color of GHS labels on glue packaging.Choosing a professional agent essentially transforms uncertain customs clearance risks into predictable service costs.For medium and large enterprises with annual import volume of more than 50 shipments,the hidden cost saved far exceeds the agency fee itself.
