Import Tips
• Submit technical data sheets confirming plasticizer function and phosphonate ester composition
• Check REACH-like registrations if from EU; ensure TSCA pre-manufacture notice if new chemical
• Prevent confusion with polyester plasticizers under 3824.99 by highlighting methylphosphonic acid base
