Are hot melt adhesive particles dangerous goods? Clear explanation of transportation, warehousing, and customs compliance in one go

Conclusion: Conventionalhot melt adhesiveParticles are not classified as dangerous goods

Conventional EVA and APAO based hot melt adhesive particles are not classified as dangerous goods. It is a solid particle at room temperature, free of organic solvents, with a flash point generally above 250 ℃. It is neither flammable nor explosive, and is not listed according to GB 12268 “List of Dangerous Goods” and the “United Nations Recommendations on the Transport of Dangerous Goods”. Therefore, highways, railways, and sea transportation can all be carried as ordinary goods without the need for dangerous goods certificates or declaration of dangerous goods on the waybill.

Why is this question repeatedly asked

Most misunderstandings come from three places. The word ‘hot melt’ evokes associations with high temperatures and open flames; Secondly, procurement personnel have seen that solvent based adhesives are managed as hazardous chemicals, so they classify all adhesives as one category; Thirdly, in order to avoid liability, some freight forwarders are required to provide a dangerous goods appraisal certificate when encountering the word “glue”. In fact, the risk of solvent based adhesives comes from volatile solvents such as toluene and ethyl acetate, while hot melt adhesive particles are 100% solid content bulk adhesives, and there are no solvents in the formula. The risk levels of the two are completely different.

The real troubles that procurement and warehouse management will encounter

Although it is not classified as dangerous goods, it will still get stuck during the process. Common situations include: customs requiring non hazardous identification reports during export declaration; Factory safety review requires supplementary MSDS/SDS; What fire hazard category should be set up for the rubber granule warehouse during the fire inspection. These are not questions of whether they are dangerous goods or not, but rather questions of whether the material specifications have been prepared.

Two types of adhesives that require separate attention

• PUR reactive hot melt adhesiveMoisture curing type contains isocyanate groups, and some grades may have sensitization prompts in SDS. Transportation is generally classified as non hazardous, but storage should be sealed and moisture-proof, and gloves should be worn during operation.
• Customized adhesive containing special functional additivesVery few flame retardant or conductive formulas may introduce controlled ingredients. The SDS conclusion of this brand should prevail, and general conclusions should not be applied.

Practical suggestions for warehousing and on-site operations

Although hot melt adhesive particles are not dangerous goods, they still belong to materials that are sensitive to moisture, sunlight, and high temperatures. It is recommended to control the temperature in the warehouse below 35 ℃, store them off the ground and walls, and avoid direct sunlight and rain; After the arrival of summer containers, they should be spread and cooled down before being stored to reduce clumping. After opening, the bag opening should be tightly sealed to prevent moisture absorption and the formation of bubbles and white spots during the melt adhesive process.

FAQ

Q: Can I send hot melt adhesive particle samples by express delivery?
Answer: Sure. As a non hazardous general cargo, normal delivery is sufficient. It is recommended to attach an MSDS with the sample to avoid misjudgment and rejection by the branch due to the word “glue”.

Q: Should non hazardous identification reports be made for every batch?
Answer: No need. The identification report of the same brand and formula can be reused within the validity period, and only needs to be reissued after changing the brand or adjusting the formula.

Q: Who do you need MSDS from?
Answer: Request from the manufacturer. Guangzhou Sunlife TradingSunlife Hot Melt AdhesiveMSDS, ingredient description, and non hazardous identification data required for export can be provided for each series of brand names. Commonly used models for book binding, packaging and sealing, and graphic printing have ready-made documents, which can usually be sent out on the same day without affecting the progress of customs declaration and review.

Simply put, regular hot melt adhesive particles are not dangerous goods, but preparing MSDS and non hazardous identification papers can help you avoid many detours during customs declaration, safety assessment, and fire inspection. Choosing a supplier who can consistently provide complete compliance documents is much more cost-effective than temporarily supplementing materials afterwards.
