Import Tips
• Technical grade isobutanal with 95-98% purity is still a separate chemically defined compound; impurities are allowed under Chapter 29 note 1(a)
• Provide the exact purity and impurity profile on the commercial invoice
• If the product is used as an intermediate, no special permits are needed, but ensure it is not a fuel additive excluded by Chapter 27
