HS Code for Engine Oil

Engine oil and related lubricants branch mainly by their base: lubricants derived from petroleum or bituminous minerals point toward heading 2710, while lubricating preparations that are not petroleum-based point toward heading 3403 in chapter 34. Within heading 2710, the form matters too; lubricating oils with additives sit on a different line than lubricating greases. The primary factor is whether the lubricant is a petroleum oil or grease, or a preparation built on a non-petroleum base. Duty treatment varies with that split: petroleum oils and greases carry small specific rates expressed per barrel, while non-petroleum lubricating preparations carry a percentage rate. Identifying the base and the form is the first step in exploring the most appropriate heading.

Engine oil is usually a lubricating oil derived from petroleum, and lubricating oils and greases obtained from petroleum or bituminous minerals point toward heading 2710. A finished motor oil that carries performance additives points toward the 'lubricating oils with additives' line at 2710.19.30, while a petroleum-based grease points toward the lubricating-greases line at 2710.19.45. The presence of additives and the physical form (oil versus grease) are the branches that separate these subheadings.

When the lubricant is not built on a petroleum or bituminous-mineral base (many fully synthetic lubricants, and preparations whose main function comes from non-petroleum components) it points instead toward heading 3403, the provision for lubricating preparations. A useful rule of thumb inside these headings is the proportion of petroleum oils: a preparation in which petroleum or bituminous-mineral oils make up 70 percent or more by weight tends toward heading 2710, while one below that threshold, or built on other bases, tends toward heading 3403. That composition test is worth confirming against the actual formulation.

Within heading 3403 the non-petroleum lubricating preparations point toward 3403.19, with the residual line at 3403.19.50 covering preparations not otherwise specified. This is where many synthetic engine and machine lubricants are explored when they fall outside the petroleum-oil headings.

A practical approach is to identify the base first (petroleum oil, petroleum grease, or a non-petroleum preparation), and then confirm the form and the 70-percent composition point. That sequence usually points toward a single most-appropriate heading to explore. It is generally better to stay with the lubricant headings 2710 and 3403 than to reach for broad chemical-preparation or automotive-parts headings, which are intended for different goods.

Duty treatment for engine oil and lubricants depends on the base and form. Petroleum-based lubricating oils with additives carry a small specific rate expressed per barrel (around 84¢/bbl), and petroleum-based lubricating greases a lower per-barrel rate (around 10.5¢/bbl). Lubricating preparations that are not petroleum-based, under heading 3403, carry a percentage rate around 5.8%. Because the petroleum lines use specific per-barrel rates and the non-petroleum line uses an ad valorem rate, the estimated duty can move noticeably depending on which base applies, so confirming the base is worthwhile. Preferential rates under free trade agreements or programs such as the Generalized System of Preferences may reduce or eliminate duties for qualifying origins. These figures are estimates for general planning purposes only.
