Flash Point refers to the lowest temperature at which a flammable liquid, under specific test conditions, emits vapor that can form a mixture with air and momentarily flash when exposed to an open flame. In foreign trade, flash point mainly concerns the transportation, warehousing, and customs declaration of dangerous goods such as chemicals, oils, coatings, and solvents. Use cases include: determining whether goods are flammable liquids (usually flash point ≤60°C is flammable), thereby applying dangerous goods regulations such as IMDG and IATA; packing group classification (e.g., flash point <23°C is Packing Group I, 23-60°C is Group II, 60-93°C is Group III); MSDS preparation and transport document declaration. Notes: different test methods (closed cup/open cup) yield different results, and the method must be specified; flash point is not fire point, it only indicates the lowest temperature for flash ignition; low flash point goods often require special packaging and segregation. Differences from fire point and autoignition temperature: fire point requires sustained combustion, autoignition temperature requires no ignition source. Foreign trade practitioners should accurately provide flash point data to avoid fines or accidents caused by misdeclaration.
📝 Examples
1. When exporting a batch of paint thinner, the MSDS indicated a flash point of -4°C, so we booked it as Class 3 flammable liquid and used Packing Group II. (Note: Flash point determines dangerous goods classification and packing group.)
2. The customer requested industrial cleaning agents with a flash point not lower than 60°C, so they could be shipped as ordinary non-dangerous goods to reduce costs. (Note: Flash point directly affects transport mode and compliance requirements.)
