Importing Under HTS 730110: What Importers Ask
How do I verify the correct HTS classification before importing?
Request a binding ruling from CBP's National Commodity Specialist Division. The ruling is valid for 5 years and is binding on all CBP ports. Alternatively, consult a licensed customs broker for a classification opinion. Misclassification can result in retroactive duties and Section 592 penalties.
Can I get duty-free treatment under an FTA for this product?
Check the Special rate column on this page for FTA preferences. If a preferential rate is listed, verify your product meets the FTA's specific rules of origin. All FTAs require origin certification — USMCA, KORUS, and others have specific documentation requirements.
What documentation is required at the port of entry?
At minimum: commercial invoice, packing list, bill of lading, and CBP Form 7501 (Entry Summary). Depending on the product, additional documentation may include FTA certificate of origin, FDA prior notice, USDA phytosanitary certificate, or TSCA certification. CBP may request the foreign supplier's manufacturing records.
HTS Chapter 73 Classification Guide: Articles of Iron or Steel
Chapter 73 covers manufactured articles of iron or steel — tubes, pipes, structural components, fasteners, nails, screws, springs, stoves, and household articles. Classification depends on the article's function and form, not the steel grade. Note that tools and cutlery fall under Chapter 82, not Chapter 73.
Common Misclassification Errors
- Classifying steel tools under Chapter 73 instead of Chapter 82 (tools and cutlery) — hand tools, cutlery, and interchangeable tool heads belong in Chapter 82
- Confusing pipe and tube subheadings — different end uses (line pipe vs. oil country tubular vs. structural) have separate subheadings with different ADD/Section 232 treatment
- Failing to recognize that Section 232 derivative product expansion now covers certain fasteners (7317-7318)
Duty Calculation Tips for HTS 730110
Steel articles face Section 232 (25%) and the 2024 derivative product expansion covers nails, staples, and fasteners under headings 7317-7318. Anti-dumping duties on steel pipe and tube products from multiple countries range from 10-85%. Verify whether your product falls under the original Section 232 proclamation or the derivative expansion.
What Importers Need to Know About HTS Chapter 73
This subheading falls under an HTS chapter covering articles of iron or steel including tubes, pipes, structures, fasteners, nails, screws, springs, stoves, and household articles. Importers of these products should be aware of the following trade compliance considerations:
Steel articles (Chapter 73) are subject to Section 232 25% tariff and derivative product expansion (2024). Verify whether your product falls under the derivative products list or the original steel proclamation.
For the specific subheading HTS 730110, we recommend you:
- Verify the correct 10-digit statistical suffix — even within a 6-digit subheading, duty rates can differ significantly between suffixes
- Check FTA eligibility — if your product qualifies for preferential treatment under USMCA, KORUS, or another FTA, you may reduce or eliminate duties by providing the required origin certification
- Monitor for trade remedy changes — Section 301, Section 232, and anti-dumping duties are updated periodically. A rate that was correct last quarter may have changed
- Consult CBP resources — for binding classification rulings, CBP's National Commodity Specialist Division provides written determinations
Chapter 73 Frequently Asked Questions
What steel articles are covered by the Section 232 derivative expansion?
The 2024 Section 232 derivative expansion covers downstream products made from steel, including nails, staples, tacks, and fasteners under HTS headings 7317-7318. If a product contains steel and is not explicitly excluded from Section 232, assume the 25% tariff applies until verified otherwise.
How are steel pipes and tubes classified differently?
Steel pipes and tubes have multiple subheadings based on end use: line pipe for oil/gas (7304), casing and tubing for drilling (7304), structural tubing (7305-7306), and other tubes. The classification depends on the product specifications, wall thickness, and stated end use. Each category may have different ADD/CVD exposure.
Do steel fasteners from China face Section 301 tariffs?
Yes, steel fasteners from China face Section 301 List 3 (25% additional duty) plus potentially Section 232 (25%) if covered by the derivative expansion. The combined effective duty rate can exceed 50% on top of the MFN rate. Sourcing from non-Section-301 countries is recommended.
Are structural steel components subject to anti-dumping duties?
Certain structural steel components face anti-dumping duties, particularly from China, Korea, and Taiwan. Standard structural shapes (beams, channels, angles) under heading 7308 may be subject to ADD depending on the country of origin and specific product. Check Commerce Department orders.
When should a steel article be classified under Chapter 73 vs. Chapter 82?
Chapter 73 covers general manufactured articles of iron or steel (pipes, structures, fasteners, springs, household articles). Chapter 82 covers tools, implements, cutlery, and interchangeable tool heads of base metal. If the item functions as a tool or cutting implement, it belongs in Chapter 82 regardless of the steel type.
