HS Code 2705.00 – Gases; coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons)
HS code 2705.00 is the 6-digit subheading for gases, coal, water, producer and similar gases (excluding petroleum and other gaseous hydrocarbons). It is used for coal gas, water gas, producer gas, synthesis gas (syngas) from coal and blast furnace gas.
What HS 2705.00 covers
This HS code covers various industrial gases derived from coal, water, or other processes, specifically excluding petroleum and other gaseous hydrocarbons (which fall under 2711). These gases, such as coal gas, water gas, and producer gas, are typically generated for industrial heating, power generation, or as chemical feedstocks. Coal gas, for instance, was historically used for lighting and heating. Water gas is produced by passing steam over hot carbon, yielding a mixture of carbon monoxide and hydrogen, valuable as a synthesis gas. Producer gas is made by passing air and steam over hot carbon. International trade in these specific gases is often limited to pipeline transfers between neighboring countries or as components within larger chemical processes, rather than extensive global shipping. Their primary use is often localized to the industrial facilities where they are produced or consumed, serving as intermediate products or direct energy sources. The economic viability and environmental impact of their production are key factors influencing their use.

Codes often confused with 2705.00
Common mistake. This code is crucial to distinguish from natural gas (271111) and other petroleum gases (2711XX), as its origin is specifically coal, water, or similar processes, not petroleum.
Top exporters and importers of HS code 270500, 2025
In 2025, the largest exporter of HS code 270500 in UN Comtrade data was the Netherlands, with 42% of world exports; the largest importer in UN Comtrade data was Italy, with 83% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).

What products fall under HS code 270500?
Coal gas, water gas, producer gas, synthesis gas (syngas) from coal, blast furnace gas, coke oven gas
What are common misclassifications for HS code 270500?
This code is crucial to distinguish from natural gas (271111) and other petroleum gases (2711XX), as its origin is specifically coal, water, or similar processes, not petroleum.
Which countries are the top exporters of goods under HS code 270500?
In 2025, the top exporters of HS code 270500 in UN Comtrade data were the Netherlands ($2.5M, 42% of world exports), Estonia ($1.4M) and Singapore ($728K). World exports came to about $5.9M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of goods under HS code 270500?
In 2025, the top importers of HS code 270500 in UN Comtrade data were Italy ($12M, 83% of world imports), the Netherlands ($422K) and France ($394K). World imports came to about $14M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
How is HS code 270500 structured?
HS code 270500 is a 6-digit subheading under the Harmonized System. The first 2 digits (27) identify the chapter, digits 3-4 (05) identify the heading, and digits 5-6 (00) specify the subheading. This code is standardized globally by the World Customs Organization.
What is the Brazil NCM code for HS code 270500?
In Brazil, HS code 270500 is NCM 2705.00.00. The last two digits are 00 because Brazil does not split this HS code further.
