HTS heading 2711 is a broad product category for petroleum gases and other gaseous hydrocarbons. It can include gases in different forms and from different sources, such as products derived from petroleum processing or natural-gas processing. At the 4-digit level, it tells you the general product family—not the final tariff classification.
To reach a specific 8-digit HTSUS code, work through the subheadings and statistical provisions under heading 2711. The key distinctions commonly involve the substance or mixture, such as whether it is liquefied, whether it is a named gas or another gaseous hydrocarbon, and its chemical composition or commercial identity. Review the full legal text, including section and chapter notes, and confirm that the product’s physical form and ingredients match the selected code.
What to check
- Identify the exact chemical name, mixture composition, and whether the product is gaseous or liquefied as imported.
- Check the product’s safety data sheet, technical specification, and manufacturing process for classification evidence.
- Read every subheading under 2711 and compare the wording with the product—not just the commercial name or marketing description.
- Confirm whether the code distinguishes a named substance, a mixture, or another type of petroleum gas or gaseous hydrocarbon.
- Verify the current HTSUS wording and consult a customs broker or binding-ruling process when composition or classification is uncertain.
HTS heading 2711 summary
Petroleum gases and other gaseous hydrocarbons is a 4-digit product category containing 7 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.

How do I choose the right code within this category?
