Complete Process Breakdown of Glue Export Customs Clearance: Avoiding the Hidden Pitfalls in Chemical Product Exports

Mr.Ji’s glue factory received a large European order last year with considerable profits.Based on past experience,he declared a batch of epoxy resin adhesive as "ordinary chemical product" for shipment.When the cargo arrived at Antwerp Port,local customs inspected the goods and detained the entire container due to the lack of mandatory GHS hazard pictograms on the outer packaging,and inconsistencies between the MSDS component information of the goods and the actual tested results.Subsequent rectification,fines,and container detention fees completely wiped out the profits,and even resulted in a loss of over 100,000 yuan.This real case occurs every day at different ports in different forms.

Glue is by no means a simple product name in the customs clearance field.It may belong to ordinary goods,or may be Class 3 flammable liquids,Class 8 corrosive substances,or even involve dual-use items control.Incorrect determination may lead to document amendment fines at minimum,or vessel schedule delays,cargo forfeiture,and even legal liability for safety accidents at maximum.Below,we abandon theories and directly enter the four practical checkpoints that must be overcome in glue export customs clearance.

First Check: Product Attribute Determination – The Starting Point of All Risks

The first step of customs clearance is not filling out documents,but "verifying the identity" of your product.This directly determines all subsequent operation processes and costs.

• Core Action: Obtain Authoritative MSDS.Do not use templates downloaded from the internet or outdated versions.It must be issued by the manufacturer or a professional testing agency in accordance with the latest version of GHS standards.Focus on verifying Part 2 (Hazard Identification),Part 3 (Component Information),Part 9 (Physical and Chemical Properties),and Part 14 (Transport Information).Among them,UN Number,Hazard Class,Packing Group are the legal basis for declaring hazardous materials for sea/air transportation.
• Key Red Line: Strictly Prohibit Misdeclaration of Non-Hazardous Goods as Ordinary Cargo.This is a behavior severely cracked down by customs and maritime authorities.In 2026,the inspection of chemical products at various ports has become very mature in MSDS verification and on-site inspection technology.Once misdeclaration is confirmed,enterprises will face heavy fines,downgraded credit levels,and even criminal liability.
• Packaging and Labels: Based on the MSDS conclusion,use packaging certified for the corresponding hazard class (such as UN containers),and post standard and durable GHS labels on the outer packaging.If a printed label is pasted on an ordinary cardboard box,it will easily wear and fall off during sea transportation,becoming an obstacle to customs clearance upon arrival.

Second Check: Domestic Export Declaration and Document Preparation

After clarifying the attributes,enter the operation layer of declaration.Here,the familiarity with the customs system and regulatory documents is crucial.

Key Points for Customs Declaration Form Filling

The product name cannot only be "glue".You must declare the accurate Chinese and English product name,model,brand,and component content.For example,"Epoxy Resin Structural Adhesive (EPOXY RESIN ADHESIVE)".HS code classification is crucial,as it is related to regulatory conditions,tax refund rates,and taxes and fees.Glue products have scattered codes,and incorrect classification may lead to inability to obtain tax refunds or additional taxes.

Dangerous Goods Declaration (DG Declaration)

If the product is determined to be hazardous materials,you must declare to the shipping company when booking space,submit the Dangerous Goods Packing Certificate (or classification society certificate),MSDS,etc.to obtain hazardous space.This is not part of the customs clearance process,but must be completed before customs clearance.Shanghai Port has extremely strict requirements for this process,with fixed time windows; missing it will cause vessel schedule delays.

Certificate of Origin Application

If the destination country is a RCEP member state (such as Japan,ASEAN) or a country with preferential tariff treatment,be sure to apply for the corresponding preferential Certificate of Origin (such as RCEP Certificate of Origin,Form E).In 2026,the tariff concessions under these agreements have entered a deepening stage; one certificate may save the client 5%-15% in tariff costs,directly enhancing the price competitiveness of your product.

Third Check: Destination Port Compliance and Risk Control in Advance

Safe departure of goods only counts as half of the success.The real challenges often lie at the destination port.

• Anti-Dumping and Trade Barrier Alerts: Some glue products or their downstream products may be subject to anti-dumping duties by countries such as Europe and the United States.Prior to export,check the latest trade remedy measures of the target country.For example,certain polymers exported to the United States may face additional tariffs.We once assisted a client named Ms.Wu in adjusting pricing and contract terms in time by alerting her to the anti-dumping investigation underway in a country before her export of sealant to that country,avoiding subsequent losses.
• Chemical Registration and Regulations (e.g.EU REACH,US TSCA): Glue exported to the EU may require pre-registration or registration under REACH for chemical substances contained,which is a mandatory requirement for customs clearance.The responsible party is usually the importer,but as the exporter,you must ensure that the product component information is transparent and traceable,and can provide a compliant SDS (Safety Data Sheet,the EU term for MSDS); otherwise,the importer cannot clear customs,and the goods will be stranded at the port.
• Customs Clearance Delay Risk: Consider the efficiency reduction caused by destination port holidays (such as the Middle East Ramadan,European and American Christmas season).It is recommended to clearly define the customs clearance responsible party (usually the client) in the contract,and reserve sufficient payment terms to avoid huge costs caused by cargo detention due to the client’s poor customs clearance,while your payment has not been fully recovered.

Fourth Check: Tax and Financial Optimization and Settlement Safety

Compliance is the bottom line,and profit is the goal.One of the core values of export agencies is to help you achieve financial optimization within the compliance framework.

Export Tax Refund: This is an important profit source for Chinese manufacturing.The tax refund rate for glue products is usually 13%.Ensuring the consistency of three streams: document flow (customs declaration form),cargo flow (bill of lading),and capital flow (overseas foreign exchange receipt) is a prerequisite for smooth tax refund.The product name and code on the customs declaration must match the invoice,and the foreign exchange receipt amount must correspond reasonably.Any inconsistency may trigger tax audits,leading to delayed or failed tax refunds.

Exchange Rate Risk Locking: The cycle from order acceptance to foreign exchange receipt may be 21 to 4 months.Exchange rate volatility remains normal in 2026.It is recommended to lock in the exchange rate through financial instruments such as forward foreign exchange settlement based on the expected foreign exchange receipt time after signing the contract,avoiding profit erosion due to exchange rate losses.We usually advise clients to calculate an exchange rate safety margin when quoting.

Foreign Exchange Receipt Safety Guarantee: For new clients or high-risk regions,prioritize payment methods such as Letter of Credit (L/C) or partial pre-T/T.Even if using Open Account (O/A),you should purchase export credit insurance to transfer the buyer’s commercial credit risk and national political risk.

Practical Review: Complex Customs Clearance of a "Simple" Glue Order

Last year,a factory in Zhejiang exported a batch of "polyurethane foam sealant" (canned with propellant) to Australia.The client initially considered it ordinary cargo.After reviewing its MSDS,we found that the product is Class 2 hazardous material (flammable gas).We immediately launched the hazardous material export process:

• Assisted the factory in applying for the Dangerous Goods Packing Certificate;
• Declared hazardous space to the shipping company and arranged hazardous material trailers to enter the dangerous goods warehouse in Shanghai Waigaoqiao;
• During customs clearance,accurately declared UN1950,Hazard Class 2.1;
• Meanwhile,applied for a China-Australia FTA Certificate of Origin (Form A) for the client to enjoy tariff concessions.

After the goods arrived in Australia,customs clearance was smooth due to complete documents and standard labels.The client was very satisfied with this cooperation due to the tariff savings and established long-term entrustment.This case shows that a professional agency is not a "runner",but by identifying risks in advance and conducting compliance operations,it simplifies the seemingly complex process and ultimately ensures the safety and efficiency of the trade chain.

In glue exports,technical details determine success or failure.Instead of paying high "tuition fees" for customs clearance problems afterwards,it is better to clarify all links in advance with an agency team with practical experience in chemical products.As a team based in Shanghai,with service networks covering major domestic ports and major overseas agents,we have handled a large number of various adhesive products exported from Shanghai,Ningbo,Shenzhen and other places,and are familiar with the regulatory characteristics and time windows of different ports.No matter which city your cargo departs from or where the destination is,the key is to follow a fully compliant path from the very beginning.
