HTS heading 7310 groups certain containers made of iron or steel when their capacity is not more than 300 liters. It covers items such as tanks, casks, drums, cans, boxes, and similar containers, including containers that are lined or heat insulated. The heading generally applies when the container does not have mechanical or thermal equipment built in, and it does not cover containers for compressed or liquefied gas.
Heading 7310 is a 4-digit category, not usually the final classification used for entry. To reach the specific 8-digit HTSUS code, read the subheadings beneath 7310 and follow the applicable distinctions, which can include the container’s type, capacity, construction or material details, and other listed characteristics. The final digits may also provide statistical detail. Classification can depend on the product’s actual design and intended use, so unusual containers may require customs-broker or classification specialist review.
What to check
- Confirm that the container is primarily iron or steel and has a capacity of no more than 300 liters.
- Check whether it is intended for compressed or liquefied gas; if so, do not assume heading 7310 applies.
- Verify that the container has no built-in mechanical or thermal equipment, such as powered cooling or heating machinery.
- Measure the container’s capacity and identify its form—such as a drum, can, box, tank, or another similar container—using product specifications and drawings.
- Read every 7310 subheading and the relevant Section and Chapter Notes in the current HTSUS, then confirm the 8-digit code against the product’s construction and features.

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.
