Import Tips

• Declare exact concentration on commercial invoice; discrepancies can trigger penalties under CBP valuation rules

• Comply with EPA pre-manufacture notice if used in mixtures post-import; track for TSCA regulations

• Avoid pitfall of mislabeling as 'lye solution' without NaOH specification, leading to classification challenges
