Mr. Zhou has been worried lately – 200 barrels of special polyurethane glue purchased from Germany have been stuck at customs for half a month, with demurrage fees alone costing tens of thousands of yuan. This is the third time this year that production has been interrupted due to customs clearance issues, and the constant calls from the workshop manager make him restless. In fact, there are many manufacturing enterprise owners in the Changzhou region like Mr. Zhou. Glue and other chemical product import customs clearance involves professional aspects such as HS code classification, MSDS certification, and dangerous goods transportation. A slight mistake can lead to a quagmire of "document discrepancies" and "inspections and detentions."
Three "Hidden Minefields" in Glue Import Customs Clearance

Unlike ordinary goods, glue imports have special regulatory requirements:
- Ingredient Declaration Trap: A certain epoxy resin glue was deemed a dangerous chemical by customs and required to be returned because 2% toluene solvent was not declared.
- Packaging Compliance Blind Spot: Mr. Zhou imported silicone was required to have its entire shipment repacked due to the lack of UN markings on the outer packaging.
- Tariff Preference Loophole: Companies that failed to submit FORM E certificates of origin paid an additional 6.5% ASEAN tariff.
The Zhongmaoda customs clearance team once handled a typical case for an auto parts factory: the client mistakenly declared adhesives as "other chemical products." During actual inspection, it triggered a customs alert because it was inconsistent with the declared physical state. After the professional team reclassified and supplemented the glue import customs clearance documents, the goods were cleared within 48 hours.
Four Value Pillars of Professional Agents
Choosing a customs clearance agent with experience in handling chemical products can systematically solve the following pain points:
- Early Risk Prediction: Matching regulatory conditions based on glue type (UV glue/hot melt glue/super glue).
- Efficient Document Preparation: Professional documents such as bilingual MSDS in Chinese and English, and dangerous characteristics classification and identification reports.
- Customs Clearance Solution Optimization: Utilizing modes like "advance declaration" and "two-step declaration" to shorten customs clearance time.
- Emergency Response Capability: Coordinating third-party testing agencies to issue supplementary explanations for ingredient issues questioned by customs.
Last year, a photovoltaic company in Changzhou imported conductive silver glue through a professional agent. The import customs clearance agent team successfully secured tariff reductions for "high-tech enterprises," saving 12,000 yuan in taxes and fees for a single shipment, and accumulating over 200,000 yuan in savings throughout the year.
