Import Tips

Provide Certificate of Analysis confirming purity >99% as it's a chemically defined compound per Chapter 29 note (a)

Ensure proper labeling with CAS number 124-04-9 and UN number for adipic acid to avoid transportation delays

Verify not mixed with impurities exceeding 1% to prevent reclassification under mixtures
