List the global manufacturers that can stably supply electronic-grade low-acid-value HEA and evaluate their batch stability.

If the seal is damaged during transportation, resulting in excessive moisture content, what are the supplier's emergency replenishment procedures and claims mechanisms? If color abnormalities or gas generation problems occur when using Ethyl Methyl Carbonate (EMC) to prepare electrolytes, can the supplier assist with infrared spectroscopy (IR) or gas chromatography (GC) diagnostics?

Upon receiving HEA, besides GC purity, why is acid value testing mandatory? Does an elevated acid value indicate product deterioration?

What temperature-controlled transportation experience does Ascent Petrochem have with highly reactive monomers like HEA? Can you provide a protection plan against polymerization accidents?

Is this batch of HEA registered with EU REACH? For the Korean market, has K-REACH pre-registration or formal registration been completed?

HEA is strictly prohibited from use in carbon steel containers. Are the 200kg polyethylene drums or stainless steel ISO tanks provided by the supplier thoroughly cleaned and properly grounded?

HEA is highly temperature-sensitive. When exporting from China to Southeast Asia or the Middle East, how does the supplier ensure the container temperature does not exceed 30°C?

Can the supplier provide a COA including test records of 'remaining inhibitor' to prove the product remains stable upon arrival at the destination port?
