HTS Chapter 27 covers mineral fuels, mineral oils, and products made from them. It includes coal and lignite, coal-tar distillation products, petroleum oils and preparations, petroleum gases, mineral waxes, petroleum coke, bitumen, natural asphalt, oil shale, and related residues. The correct provision depends on the product’s composition, source, processing, and sometimes its physical form—not simply on how the product is marketed or used.
The HTS is organized in levels: a chapter is a broad product section; a heading is a four-digit category, such as 2710 for certain petroleum oils and preparations; a subheading adds detail at six digits; and the full U.S. classification is generally a 10-digit HTSUS code. Start with the product’s objective facts, compare the relevant heading and subheading descriptions, read the legal notes and exclusions, and verify the complete 10-digit code and any applicable Chapter 99 provisions using current official HTSUS information. Classification questions involving complex mixtures, chemical analysis, or competing provisions may require a customs broker or other qualified classification professional.
What to check
- Identify the product’s source, chemical composition, processing method, physical state, and principal ingredients before choosing a heading.
- Distinguish crude products, refined or distilled products, preparations, residues, wastes, and manufactured solid fuels; similar commercial names can classify differently.
- Read the Chapter 27 notes, heading notes, and exclusions, including provisions that direct certain products to another chapter or heading.
- Check whether the product is a mixture or preparation and whether the tariff text uses composition thresholds, essential-character rules, or stated exclusions.
- After finding the base HTSUS code, check current U.S. tariff measures and any applicable Chapter 99 provisions separately; confirm the result with official sources or a customs professional when facts are uncertain.
How to use this chapter
A chapter is the first classification level, not a duty rate. Choose the heading that describes the product, narrow by material, construction, use, or other legal distinctions, and verify the final line against the official HTS notes.

Questions about HTS Chapter 27
What does HTS Chapter 27 cover?
HTS Chapter 27 covers Mineral fuels, mineral oils and products of their distillation. This page groups the chapter’s 4-digit headings; a shipment still needs the most specific active 8- or 10-digit line supported by the product facts.
Is HTS Chapter 27 a final product classification?
No. A chapter is a broad 2-digit category. Narrow it to the applicable heading and the most specific active statistical line before estimating duty or filing an entry.
