Import Tips
• Include technical data sheet confirming use as pure chemical, not pre-mixed fluid, to prevent reclassification
• DOT classification as non-hazardous is key; mislabeling as corrosive leads to additional fees
• For oilfield imports, link to end-use permits if required by state regulations
