Zinc Naphthenate Anti-Corrosion Primer
Zinc naphthenate, a water-insoluble zinc salt of naphthenic acids, serves as a rust-inhibiting primer for metal surfaces in marine and industrial applications. Classified under HTS 3824.99.75 due to its primary composition as naphthenic acid salts meeting the water-insoluble criterion. It is used in protective coatings rather than as a finished paint.

Import Tips & Compliance
• Provide detailed chemical composition certificates confirming >50% naphthenic acid salt content
• Check for VOC compliance and include emission test results for environmental clearance
• Label clearly as 'industrial primer base' to prevent classification as ready-to-use paint under Chapter 32
