Import Tips & Compliance
• Declare exact salt stoichiometry in technical documentation per chapter note 5(C)(1) for organic salts
• Water-dissolved forms acceptable only if per chapter note (d); otherwise classify as solid salt
• Avoid retail packaging that could trigger Chapter 38 prepared chemical classification
