Copper Naphthenate Wood Preservative

Copper naphthenate is a water-insoluble salt of naphthenic acids used as a fungicide and insecticide for pressure-treated wood products like decks and fences. It falls under HTS 3824.99.75 as it is specifically a water-insoluble salt of naphthenic acids prepared for industrial preservative applications. This classification covers such metallic naphthenates not elsewhere specified in Chapter 38.

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.

Naphthenic Acid Methyl Esters

Methyl esters of naphthenic acids are used as synthetic lubricants and plasticizers in industrial formulations. This product qualifies for HTS 3824.99.75 as it consists of esters derived from naphthenic acids, not elsewhere specified. They provide solvency properties in oil-based mixtures.

Barium Naphthenate Paint Drier

Barium naphthenate acts as a drier catalyst in alkyd paint formulations, accelerating oxidation and drying of oil-based coatings. It is imported as a water-insoluble naphthenic salt under HTS 3824.99.75 for use in the chemical/paint industry. This excludes finished paints classified elsewhere.

Cobalt Naphthenate Catalyst

Cobalt naphthenate serves as a polymerization catalyst in polyester resin production and as a paint drier. As a water-insoluble salt of naphthenic acids, it precisely matches HTS 3824.99.75 classification for industrial chemical preparations. Concentration typically 6-10% cobalt metal content.

Lead Naphthenate Industrial Lubricant

Lead naphthenate provides extreme pressure lubrication properties in metalworking fluids and gear oils. This water-insoluble lead salt of naphthenic acids imports under HTS 3824.99.75 as an industrial chemical preparation. Restricted use due to lead toxicity regulations.
