Common questions
- What is HTS code 7306?
- HTS heading 7306 covers other tubes, pipes and hollow profiles (for example, open seamed or welded, riveted or similarly closed), of iron or steel. It sits in Chapter 73 (iron and steel articles) of the US Harmonized Tariff Schedule and contains 68 tariff lines.
- What is the duty rate for HTS 7306?
- Duty-free under the general rate. The general rate applies to most-favoured-nation trading partners; goods from countries with a free trade agreement may qualify for a reduced or duty-free special rate.
- How many digits does a full HTS code have?
- US import entries require the full 10-digit HTS code. Heading 7306 is the first four digits — the remaining six narrow it down to the specific product, which is what determines the duty rate you actually pay.
