Import Tips
• Obtain EPA TSCA pre-manufacture notice if not on inventory; verify catalyst composition for REACH-like compliance
• Include detailed technical data sheets and safety data sheets (SDS) for customs; check for precious metal content declarations
• Avoid misclassification as finished auto parts (8708); common pitfall is undervaluing platinum content
