Common questions
- What is HTS code 2937?
- HTS heading 2937 covers hormones, prostaglandins, thromboxanes and leukotrienes, natural or reproduced by synthesis; derivatives and structural analogues thereof, including chain modified polypeptides, used primarily as hormones. It sits in Chapter 29 (organic chemicals) of the US Harmonized Tariff Schedule and contains 28 tariff lines.
- What is the duty rate for HTS 2937?
- 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 2937 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.
