Methyl Benzoate: Flash Point 82 C, Still Class 6.1
Methyl Benzoate: Flash Point 82 C, Still Class 6.1
Executive Summary
A 150 kg shipment was held at Dalian. The flash point said safe. The catalogue said otherwise.
Overview
Let me be direct. The flash point habit comes from one rule. For sea transport, Class 3 flammable liquids are cut at a flash point of 60 degrees Celsius, closed cup. Somewhere along the way that hardened into a folk rule: above 60 degrees Celsius, it is general cargo. Frankly, that rule only ever applied to Class 3.
Class 6.1 is about toxicity, not fire. Class 8 is about corrosion. Class 9 covers environmental harm and everything else that does not fit. None of them look at flash point. Methyl benzoate sits in Class 6.1 with an oral LD50 of 3430 mg/kg in rats. The Dalian case involved 150 kg across 10 drums. It is toxic. That is the whole argument.
Put simply, the catalogue decides, not the drum. If a name appears on the national hazardous chemicals catalogue, it moves as a hazardous chemical in China. Your experience is not evidence.
Watch out for this one. A clear liquid with a pleasant smell is exactly what a toxic substance looks like.
Key Details
Here is the full profile. Methyl benzoate, CAS 93-58-3, molecular formula C8H8O2, UN 2938, Class 6.1 toxic substance, Chinese dangerous goods code 61624, Packing Group III, flash point 82 degrees Celsius, boiling point 198 degrees Celsius, relative density 1.09.
It has two jobs: fragrance and solvent. So it shows up on orders from flavour houses, cosmetics makers, coatings and ink producers. Bottom line: most of those buyers have no idea what they are shipping.
Packing Group III is the lightest of the three, and that is where people relax. Do not. You still need certified UN packaging, a packaging performance test report and a use-appraisal report. Three documents. All of them.
Looking Ahead
Check one. Run every product name against the national hazardous chemicals catalogue before you quote. Not after booking, before quoting. The same product name with a different formulation can land in a different class.
Check two. Read the label on the drum. That is what the officer at Dalian read first. Look for a pictogram and a signal word. No pictogram on a chemical drum is a warning sign on its own.
Check three. Ask for the hazard classification report, not only the MSDS. The MSDS is written by the manufacturer. The classification report comes from an accredited laboratory. The catch is that Chinese customs accepts the second one.
Now the money. A confirmed misdeclaration is fined at 5% to 20% of cargo value, capped at 200000 yuan, and the maritime authority can fine you again on top. A case published by Qingdao MSA on Sept. 14, 2026 carried 90000 yuan. Add re-export, demurrage and 3 to 5 days of storage. Is your margin built for that?
Market Outlook
If you move fragrance compounds, solvents or coating additives into Tianjin, Dalian, Qingdao or Shanghai, the sequence is the same every time: catalogue check, label check, classification report. Frankly, the forwarders who build that sequence into their quotation stage will be the ones still booking smoothly when the next case is published.
