When I first began managing international shipments of custom steel parts, I didn’t realize how essential the correct HTS code was. One mistake in classification meant unexpected duties, customs delays, and even penalties. Over time, I learned how to accurately identify HTS codes and calculate the right tariff rate, which helped my team avoid costly surprises. If you're importing custom steel parts into the U.S., understanding the HTS (Harmonized Tariff Schedule) system is not just helpful—it's essential.
To find the HTS code and tariff rate for custom steel parts, importers should use the official U.S. Harmonized Tariff Schedule [^1] online tools, verify product classifications carefully, and account for additional duties like Section 232 and AD/CVD. It is also wise to consult Customs Rulings and licensed brokers for accurate classification.
What is the HTS Code for custom steel parts?
The HTS Code for custom steel parts depends on the part’s design, use, and material. HTS codes are 10-digit numbers used to classify goods for U.S. imports. The first six digits are standardized globally, and the last four are specific to the U.S.
Custom steel parts can fall under several HTS headings depending on factors like whether they are machined, stamped, or assembled. For example:
- A machined stainless steel bracket might fall under HTS 7326.90.8688
- A forged carbon steel gear component might fall under HTS 8483.90.5000
How to Interpret the HTS Code Structure
Each part of the HTS code carries meaning. Here’s a breakdown:
| HTS Code Section | Meaning | Example: 7326.90.8688 |
|---|---|---|
| 7326 | Chapter (e.g., iron/steel articles) | |
| .90 | Subheading (e.g., other articles) | |
| .8688 | U.S.-specific code for product details |
Each code corresponds to a specific product description, and selecting the correct one is critical for applying the right tariff rate.
How can I determine the tariff rate for my steel parts?
You can determine the tariff rate for your steel parts by checking the rate listed under your HTS code in the U.S. Harmonized Tariff Schedule. This includes the General rate (for most countries), Special rates (for countries with trade agreements), and Column 2 (for non-normal trade relations).
Many custom steel parts have low or even zero base tariffs under the General rate. However, that’s not the end of the story. You must also account for additional tariffs like:
- Section 232 (25%) on all steel products, regardless of origin [^2]
- Section 301 tariffs for Chinese-origin goods
- Anti-Dumping (AD) or Countervailing Duties (CVD) [^3], if applicable
Steps to Calculate the Total Tariff
- Start with the General rate from the HTS.
- Add Section 232 tariffs if the product is made of steel.
- Check for Section 301 tariffs if the origin country is China.
- Verify AD/CVD investigations using U.S. government resources.
| Tariff Type | Typical Rate | Applies To |
|---|---|---|
| General Tariff | 0%–5% | Most countries and steel categories |
| Section 232 | 25% | All steel products |
| Section 301 | 7.5%–25% | Products from China |
| AD/CVD | Varies | Country/product-specific cases |
Are there online tools to look up HTS Codes and duties?
Yes, there are several free online tools provided by U.S. government agencies to help you look up HTS codes and calculate import duties.These tools can guide you through the classification and provide legal descriptions of each tariff heading.

Do different steel products have varying HTS Codes and tariffs?
Yes, different steel products have different HTS codes and potentially different base tariffs. The specific classification depends on how the part is made, its use, material composition, and degree of machining.
Custom steel parts may fall under multiple headings depending on these details. For example, machined steel bushings and stainless steel clamps will each have different codes—and potentially different duties. Even small differences like being “hot-forged” vs. “cold-rolled” can affect the HTS code.
Examples of HTS Variations
| Product Description | Material Type | Possible HTS Code | Notes |
|---|---|---|---|
| Machined Bracket | Stainless Steel | 7326.90.8688 | Subject to Section 232, maybe AD/CVD |
| Forged Gear Housing | Carbon Steel | 8483.90.5000 | Precision-machined, used in machinery |
| Pipe Flange | Alloy Steel | 7307.21.1000 | Often included in piping systems |
| Mounting Plate (cut but not machined) | Iron/Steel | 7326.90.85XX | Base component, low processing level |
Because of this complexity, proper classification is critical. Misclassification can result in underpayment or overpayment of duties, fines, or shipment delays.
Final Tips for Accurate HTS Classification
- Use clear product specifications and detailed drawings.
- Confirm material types and dimensions.
- Cross-check similar CBP rulings on CROSS [^4].
- If uncertain, consult with a licensed customs broker [^6].
Conclusion
To correctly determine the HTS code and tariff rate for your custom steel parts, you must combine product knowledge with the right tools. Use HTS.USITC.gov to find accurate codes, review CROSS for rulings, and always account for extra tariffs like Section
