Market Background and Common Difficulties of Nanjing Glue Imports

As a core manufacturing hub in East China,Nanjing’s demand for imported glue in industries such as electronic assembly,high-end construction and auto parts continues to rise in 2026.Industrial-grade glue from brands like Henkel of Germany,ThreeBond of Japan and Loctite of Korea has become a hot procurement item for local enterprises due to its advantages in temperature resistance,bonding strength and environmental protection indicators.However,such glue falls under the category of dangerous chemicals,and import customs clearance often gets stuck in two key links: first,documents do not meet national standard requirements,and second,commodity inspection labels and test indicators fail to meet standards.

In October last year,Mr.Shi from a building materials company in Nanjing encountered a similar problem: he planned to import a batch of German architectural sealants.The MSDS (Material Safety Data Sheet) provided by the supplier only marked "flammable" and did not specify "Flammable Liquid Category 2" in accordance with China’s GB/T 17519-2013 standard.After the goods arrived at the port,Shanghai Yangshan Port Customs requested rectification,delaying delivery by 12 days and directly affecting the order delivery to downstream real estate enterprises.

Core Role of Zhongshen in Nanjing Glue Imports

In response to the pain points of Nanjing enterprises importing glue,the core value of Zhongshen lies in "early intervention + accurate matching of compliance requirements" —— instead of waiting until the goods arrive at the port to handle matters,we intervene in document pre-review before the enterprise signs the purchase contract.At the same time,we are familiar with the latest regulatory rules for chemical products issued by Nanjing Customs (such as the policy that RCEP member countries’ glue tariffs will drop to 3.5% in 2026) to avoid delays and cost increases caused by information gaps.

Breakdown of Core Procedures for Nanjing Glue Import Customs Clearance

I.Document Pre-review Stage: Secure the First Compliance Checkpoint

The document requirements for glue imports are much higher than those for ordinary goods.The core compliance points include:

• MSDSmustcomplywithChina’sGB/T17519-2013nationalstandard,andtheChinesetranslationmustbeissuedbyaqualifiedinstitution;
• DangerousCharacteristicsClassificationandIdentificationReport:ForClass3(flammable)andClass8(corrosive)glue,itmustbeissuedbyaCMA-certifiedinstitution;
• Architecturalgluemustprovideanimportpaintregistrationcertificate(completedinadvancethroughtheChinaNationalCoatingsIndustryAssociation);
• ToenjoyRCEPtariffpreferences,acertificateoforiginfromthemembercountry(inaformatcompliantwithcustomsrequirements)mustbeprovided.

How Zhongshen assists: Before the enterprise signs a contract with a foreign supplier,we require the supplier to provide a draft of documents for review by our chemical customs clearance specialist.In March 2026,when Mr.Lu from an electronics factory in Nanjing imported Japanese electronic glue,Zhongshen found that the supplier incorrectly declared the customs code as "3506100000 (acrylic adhesives)",while the actual code should be "3506919090 (other prepared adhesives)".After adjusting the code in advance,we not only avoided customs questioning but also enjoyed RCEP tariff preferences,saving approximately 12% of import costs.

II.Port Customs Declaration Stage: Accurately Match Codes and Tariff Rates

The customs code classification of glue directly affects tariffs and regulatory requirements.In 2026,Nanjing Customs requires 12 declaration elements for glue (including component content,usage,brand,model,whether it is water-based,whether it is hot melt adhesive,etc.).Zhongshen’s customs declaration team is familiar with the classification standards of local Nanjing Customs and can quickly match the optimal code: For example,for the automotive interior glue imported by Mr.Cui from an auto parts factory,after confirming the code,we can enjoy the RCEP tariff preference,reducing the tariff from 8% to 3.5%.

III.Commodity Inspection and Quarantine Stage: Early Coordination to Shorten Testing Cycle

As a chemical product,glue requires two core tests in commodity inspection:

• Qualityinspection:Confirmwhetherindicatorssuchasthebondingstrengthandtemperatureresistanceofthegluemeetthecontractrequirements;
• Safetyprojectinspection:DetectVOCcontentforarchitecturalglue(complyingwithGB18582-2020)andflameretardantratingforelectronicglue(complyingwithUL94).

Zhongshen will communicate with the Jiangsu Commodity Inspection Bureau 3 days in advance and arrange "port sampling + laboratory urgent testing" according to the needs of Nanjing enterprises.In May 2026,when Mr.Xu from a packaging factory in Nanjing imported Korean hot melt adhesive,the original 7-day testing cycle was shortened to 3 days,ensuring that the goods entered the Nanjing warehouse on time without affecting the production schedule.

Actual Case: How Zhongshen Helps Nanjing Enterprises Avoid Risks

In April 2026,Mr.Cui from an auto parts factory in Nanjing planned to import a structural adhesive from a German brand (used for automotive interior bonding).The team had no previous experience in chemical product imports and was worried that "incomplete documents" and "failed commodity inspection" would lead to production line downtime.After Zhongshen intervened,we did three things:

• Reviewedthesupplier’sMSDSandfoundthatitdidnotincludethe"VOClimitforautomotiveinteriorglue"requirement,andimmediatelyrequestedthesupplementofatestreportcomplyingwithEUECER43standards;
• Confirmedthecustomscodeas"3506919090"duringdeclaration,enjoyedRCEPtariffpreferences,andsaved62,000yuanintariffs;
• CoordinatedwithNanjingCommodityInspectionBureauduringthecommodityinspectionstage,arrangedaone-stopserviceof"sampling-testing-certificateissuance",shorteningthecustomsclearancecyclefromtheindustryaverageof10daysto5days.

In the end,Mr.Cui’s production line did not experience downtime,and procurement costs were reduced due to tariff preferences.

Comparison of Self-declaration vs.Zhongshen Agency

Conclusion: Professional Agency is the Core Guarantee for Nanjing Glue Imports

In 2026,the competition in Nanjing’s glue import market has long shifted from "whether it can be imported" to "whether it can be imported efficiently and compliantly".With more than 20 years of foreign trade agency experience,Zhongshen not only helps enterprises avoid risks in document and commodity inspection links in advance,but also reduces costs through tariff preferential policy optimization —— for Nanjing enterprises engaged in electronics,construction and auto parts,choosing a professional import customs clearance agent essentially means choosing the guarantee of "no pitfalls,no delays,and cost reduction".
