π§ͺ Ethyl Carbamate (Urethane) β HS Code & Tariff Guide 2026 | Full Customs Clearance Breakdown
π HS Code Classification & Duty Analysis | 2026 U.S. Tariff Rules | Expert Compliance Strategy
π One Product, Four Possible HS Codes β Know Which One Applies to You!
Ethyl carbamate (also known as ethyl urethane) is a nitrogen-containing organic compound used in flavoring, pharmaceuticals, and industrial synthesis. Due to its chemical structure, it can be classified under multiple HS codes depending on its functional group and intended use. This guide breaks down all four possible HS codes for ethyl carbamate, including detailed tariff explanations, legal basis for each duty, and critical customs clearance recommendations.
β οΈ Key Insight:
The correct HS code depends on chemical classification, not just the product name. Misclassification can lead to overpayment, penalties, or seizure.

π° 2026 U.S. Tariff Breakdown by HS Code (With Legal Basis)
π― 1. 2915.39.45.50 β Other Odoriferous or Flavoring Compounds
| Item | Detail |
|---|---|
| Base Tariff | 4.8% (ad valorem) |
| Additional Duty (Section 301) | +25.0% (USITC Footnote 9903.88.01) |
| Section 122 Duty (IEEPA) | +10.0% (International Emergency Economic Powers Act) |
| Total Effective Duty | 39.8% |

π Common Mistakes & How to Avoid Them
β Mistake 1: Using βethyl carbamateβ as the only product name
π Result: Customs cannot determine function β delayed clearance or incorrect classification
β Fix: Use precise description:
βEthyl Carbamate, Aliphatic Carbamate, for Chemical Synthesis, CAS: 51-79-6, 99% Purity, Made in Chinaβ
β Mistake 2: Not providing chemical structure
π Result: Customs may assume worst-case scenario β 41.5% duty
β Fix: Attach structure diagram and MSDS withη³ζ₯
β Mistake 3: Assuming all carbamates are the same
π Result: Misclassifying 2924.11.00.00 as 2924.19.80.00 β +31.5% duty
β
Fix: Review chemical structure β if it's a simple chain-like amide, use 2924.11.00.00

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) β Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) β More specific grouping within the chapter
- Subheading (6 digits) β Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) β Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate β The standard duty rate applied to WTO members
- General rate β Applied to countries without trade agreements
- Trade remedy duties β Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
