Dipropyl Ketone (4-Heptanone)
Dipropyl ketone (CH3CH2CH2COCH2CH2CH3), or 4-heptanone, is an acyclic ketone used in organic synthesis and as a high-boiling solvent. It is classified in HTS 2914.19.00.00 as 'other' acyclic ketones without additional oxygen functions, per Chapter 29 definitions. This ensures proper distinction from aromatic or quinone structures.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for technical grade with stabilizers added
Chapter note (f) allows stabilizers for qualifying ketones, but excessive additives may push to unspecified chemical preparations in 3824.
If it had an ether oxygen function
Additional ether groups classify under earlier oxygen-heterocyclic or ether headings per numerical order rule.
If saturated acyclic monocarboxylic acid derivative misinterpreted
Ketones distinct from esters/acids; misreading functional groups leads to 2915 classification.

Import Tips & Compliance
• Include GC-MS reports proving chemical purity >98% to avoid mixture classification; comply with VOC regulations
• Avoid common error of declaring as 'ketone oil' which triggers 1518/1522 vegetable oil headings
