Import Tips
• Obtain ATF import license as thiodiglycol is a List I chemical regulated under chemical diversion laws
• Provide detailed safety data sheets (SDS) and end-use statements to clear customs without delays
• Label containers properly to distinguish from mixtures; pure thiodiglycol stays in 2930, diluted forms may shift headings
