Aroma Diffuser Imports

Aroma diffuser imports classify under HTS 8543.70 (other electrical machines and apparatus) or 8509 (electromechanical domestic appliances). Section 122 stacks; Section 301 if China-origin (often List 3 at 25%). Most consumer diffusers from China.

This guide covers U.S. import tariff and compliance for aroma diffusers.

For SMB importers in this category, the practical questions are HTS classification, applicable Section 232/301/122 stacks, FTA opportunities, and regulatory overlay (FDA/USDA/EPA/CPSC where relevant).

HTS classification basics

Ultrasonic diffusers HTS 8543.70 or 8509.80. Specific subheading depends on technology.

Tariff stack and rates

Base 2.6-4.2% + Section 122 (15%) + Section 301 (25% if China-origin). Effective 17.6-44.2%.

Country of origin considerations

China dominant. Some Korean and U.S. assembly.

Regulatory overlay

UL listing for electrical safety. CPSC for child safety claims.

Mitigation opportunities

Korean KORUS preference. USMCA qualification on Mexican-assembled units.

Frequently asked questions

What is the typical effective duty rate?

Depends on origin and HTS classification. China-origin: 22-42% effective when Section 301 + Section 122 stack. USMCA-qualifying Mexican production: often 0-3%. Vietnam, India, Korea: 15-17% with Section 122.

Can I qualify under USMCA?

Possible if production occurs in U.S., Mexico, or Canada and meets rules of origin (typically 60% RVC under transaction value or 50% net cost). USMCA-qualifying goods are exempt from Section 122.
