HS Code 7309Reservoirs, tanks, vats and similar containers; for any material (excluding compressed or liquefied gas), of iron or steel, capacity exceeding 300l, whether or not lined or heat insulated
1 six-digit code · Heading 9 of 26 in Chapter 73 · World Customs Organization Harmonized System
HS code 7309 is the code for large steel tanks, reservoirs and vats that hold more than 300 litres. This page helps you check what fits and tell it apart from nearby headings.
Heading 7309does not subdivide further in the WCO nomenclature: goods answering to “Reservoirs, tanks, vats and similar containers; for any material (excluding compressed or liquefied gas), of iron or steel, capacity exceeding 300l, whether or not lined or heat insulated” classify at the single six-digit code 730900. The heading is number 9 of 26 in Chapter 73, Iron or steel articles, which runs to 124 six-digit codes in all.
Six-digit codes under heading 7309
| HS Code | Import–export description |

What HS code 7309 covers
Heading 7309 is for big storage vessels made of steel or iron. Think of a water reservoir, a fuel tank or a vat used in a factory. Anything above 300 litres can qualify.
The tank can hold almost any material. The one exception is compressed or liquefied gas. It also does not matter whether the tank has a lining or heat insulation. A lined tank and a bare tank are treated the same way.
The number comes from the WCO Harmonized System, the shared code list that customs offices use. Some traders call it the HSN code 7309. The digits are identical.
Subheading 730900 and national codes
The world list stops at six digits here, so there is nothing to choose between. Every tank in this class goes to 730900.
Your country may add more digits for its own tariff. A customs form at home can therefore show a longer number. Check your national tariff for the exact version, and keep 730900 as the base.
How to classify steel tanks: 7309 vs 7310, 7311 and 7308
Ask three questions, in this order.
First, how big is the tank? Size is the main test between 7309 and 7310. Second, what will it hold? Gas under pressure, or gas turned to liquid, moves the goods to a different heading. Third, is it a tank, or a piece built to be part of a frame or building? Frames and their parts belong elsewhere.
If you are still unsure, the HS code classifier can help you narrow it down.
- Above 300 litres: heading 7309.
- 300 litres or less: heading 7310, which also covers casks, drums, cans and boxes.
- Gas containers: heading 7311.
- Structures and parts made for them: heading 7308.

HS Code 7309: common questions
What is HS code 7309?
It is the customs heading for steel reservoirs, tanks and vats above 300 litres. Traders also write it as HSN code 7309.
What is the six-digit HS code for steel tanks over 300 litres?
Use 730900. No other six-digit code sits under this heading, although national tariffs may add extra digits.
What is the difference between 7309 and 7310?
Capacity decides it. A tank above 300 litres goes to 7309, and one of 300 litres or less goes to 7310.
Which HS code covers steel tanks for compressed gas?
Heading 7309 excludes them. Look at heading 7311, which is made for gas containers.
Do insulated or lined steel tanks fall under 7309?
Yes. A lining or heat insulation does not change the heading, provided the tank is steel or iron and holds over 300 litres.
