Import Tips

Label containers with exact chemical name and CAS number (CAS 25550-93-6) to match HTS 2931.49.00.25 specifications

Provide end-use statement if used in food-contact applications to address FDA regulations alongside tariff classification

Avoid bulk mixtures; pure compound import prevents reclassification to higher-duty mixture headings
