Import Tips

• Include stability data in documentation; solutions may require UN hazmat certification for transport

• Label concentration precisely (e.g

• 40% w/v); discrepancies lead to reclassification as mixtures

• Obtain prior EPA notification if used in US water systems; import permits may apply for large volumes
