The United States import duty structure for base oil is characterized by a combination of specific rates, environmental taxes, and administrative fees. Most base oils fall under Chapter 27 of the Harmonized Tariff Schedule (HTS), where duties are often calculated per barrel rather than purely on value. Importers must also navigate trade enforcement actions, such as Section 301 duties, which can significantly alter the total landed cost depending on the country of origin.
| Duty/Tax Type Name | Standard Rate or Rate Range |
|---|---|
| Ad Valorem Duty | 0% to 5.5% |
| Specific Duty | $0.052 to $0.105 per barrel |
| Compound Duty | Varies by HTS (Specific + Ad Valorem) |
| Section 301 Duties | 25% (applicable to China origin) |
| Antidumping (AD/CVD) | Case-specific (varies by supplier) |
| Excise Tax (OSLTF) | $0.09 per barrel |
| Merchandise Processing Fee (MPF) | 0.3464% (Min $32.71, Max $634.62) |
| Harbor Maintenance Fee (HMF) | 0.125% (Sea freight only) |
Types of Duties and Taxes:
- General Customs Duty: Most base oils are subject to specific rates per barrel or low percentage-based ad valorem rates. These are defined by the HTSUS General column 1 rates.
- Trade Defense Duties: Section 301 and Antidumping duties target specific origins to protect domestic industry. These can add substantial costs to imports from targeted countries like China.
- Environmental Excise Taxes: Federal fees like the Oil Spill Liability Trust Fund are assessed on petroleum products. These are typically specific rates applied to the volume of the import.
- Administrative Fees: MPF and HMF are user fees collected by CBP to cover processing and port maintenance. HMF is only applicable if the cargo arrives via a designated water port.
