Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dioctyl rather than dinonyl chains
Different carbon chain length (C8 vs C9) changes classification to dioctyl orthophthalates heading.
If mixed with phosphate plasticizers
Blends with non-phthalate plasticizers fall under general mixed esters category.
If for monononyl phthalate intermediates
Single ester group compounds classify under monocarboxylic acid esters rather than diesters.

Import Tips & Compliance
• Include third-party assay certificates verifying ≥99% purity; lower purity risks 2917.39.9000 classification
• Specify 'technical grade - not for food contact' on documentation to avoid FDA import alerts
• Use nitrogen-blanketed containers to prevent oxidation; degraded product may be rejected at entry
