Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If sold as vehicle for pigments
Paint pigment vehicles have specific classification outside general chemicals.
If dryer metals non-naphthenic
Substitution with octoates shifts to generic 'other' preparations.

Import Tips & Compliance
• Batch analysis showing total naphthenate >60% required; multi-metal doesn't change heading
• VOC compliance docs for US sales; import under 'chemical preparations' not mixtures
