Import Tips
• Document stabilizer composition (<1% typically) to confirm it meets 'necessary for preservation' criteria in chapter notes
• Use UN-approved drums for import; test for stabilizer volatility to prevent off-gassing issues
• Monitor MFN duty rates and Section 301 tariffs applicable to Chinese-origin MDA
