Import Duty and Tariff Strategy for LED Therapy Devices: What Most Brands Get Wrong
The Compliance Part (Which Most People Handle Correctly)
First, the basics that you probably already know:
HS code classification matters. LED therapy devices typically fall under HS code 9019.20.00.00 (mechanical therapy devices) or 8543.70 (electrical therapeutic devices). The difference in duty rate can be 2-3%. Get a binding tariff classification ruling from US Customs if you’re unsure.
Country of origin documentation is required. Your supplier must provide a Certificate of Origin. Without it, your shipment may be held or assessed at the highest duty rate.
Section 301 tariffs apply. LED therapy devices from China are subject to Section 301 tariffs. In 2025, the effective tariff rate on most LED therapy devices from China is approximately 25-30% depending on the specific product category and any active exclusion processes.
De minimis threshold. For US imports, goods valued under $800 per shipment often enter duty-free. For testing or sample shipments, this matters. For commercial quantities, it rarely does.
These are the compliance basics. Most brands handle them.
Where brands get into trouble is in treating tariff costs as fixed and unchangeable. They’re not.
Strategy One: HS Code Optimization Within the Rules
This is legal. It’s also frequently underused.
The specificity principle. In the Harmonized System, more specific product descriptions often carry different duty rates than general ones. A “red light therapy mask” may have a different rate than a “LED skin treatment device.”
We worked with a customs broker to review our product line’s HS code classifications. For one product category, moving from a general classification to a specific one reduced the duty rate by 3.2 percentage points. On a $2 million annual import volume, that was $64,000 per year in duty savings.
Product structure matters. Sometimes the same product can be assembled in ways that affect its classification. If your device includes specific features (ultrasound, radio frequency alongside LED), the classification may differ from a single-function LED device. Work with a customs broker who specializes in medical/wellness device classifications.
Chapter 84 vs. Chapter 90. Many LED therapy devices sit at the boundary between general machinery (Chapter 84) and medical/optical instruments (Chapter 90). The duty rates can differ. The right classification depends on the device’s primary function and intended use.
Strategy Two: Supply Chain Restructuring (Legal, But Requires Planning)
Third-country assembly. Some brands route components or semi-finished goods through a third country for final assembly. The device is then “made in” Vietnam, Malaysia, or Thailand — countries with lower or zero tariffs on exports to the US.
This is legal. It requires careful supply chain restructuring, and it doesn’t eliminate all compliance requirements. Rules of origin requirements apply, and your customs broker needs to be involved from the beginning.
We’ve seen brands save 15-20 percentage points in effective tariff rate through legitimate third-country assembly. The setup costs are significant (6-12 months, $30,000-100,000 in restructuring costs), but for brands with import volumes above $500,000 annually, the payback period is typically 12-18 months.
Component-level optimization. Sometimes individual components are classified differently than the finished product. If your device contains a component that can be separately classified, you may be able to reduce the overall duty burden.
Strategy Three: Tariff Exclusion Management
Section 301 tariffs are subject to exclusion processes. The Biden and Trump administrations both ran exclusion processes, and the current trade environment may see additional rounds.
Track exclusion opportunities actively. Subscribe to Federal Register notices. Work with a trade law firm or customs broker who monitors exclusion announcements in your product category.
Prepare documentation in advance. When exclusion windows open, they often close within weeks. Brands that have product specifications, tariff classification information, and import volume data ready to submit are more likely to receive exclusions.
exclusions are retroactive. If you’ve been paying tariffs on goods that later receive an exclusion, you can file for refunds. Maintain records of all import duties paid.
Strategy Four: Transfer Pricing and Contract Structure
Long-term purchase agreements. If you’ve locked in pricing with your supplier, check whether your agreement accounts for tariff changes. Some brands have found that their supplier absorbed tariff increases through margin compression — until they didn’t, and then quality suffered as a result.
DDP vs. FOB terms. Who bears the tariff cost depends on your Incoterms. Under DDP (Delivered Duty Paid), the seller handles everything including tariffs. Under FOB (Free on Board), you bear import costs. Make sure your contract clearly specifies who pays tariffs, and build in adjustment provisions for significant tariff changes.
Working capital implications. Higher tariffs mean higher landed costs, which means more working capital tied up in inventory. Model this impact on your cash flow before committing to inventory levels.
What Most Brands Get Wrong
Treating tariffs as a cost of doing business. Tariffs are a significant cost, but they’re also manageable. Brands that develop tariff strategy — not just tariff compliance — consistently outperform those that don’t.
Not using a specialized customs broker. General freight forwarders are not customs brokers. For LED therapy devices, which may have nuanced HS code classifications, work with a broker who specializes in electrical/medical device imports.
Underestimating the importance of country of origin. The Certificate of Origin isn’t a formality. It’s the document that determines which tariff rate applies. If it’s wrong, you face penalties, retroactive duty assessments, and potentially seizure of goods.
Ignoring the supply chain restructuring timeline. If third-country assembly makes sense for your business, start planning now. You won’t see benefits for 6-12 months, so earlier decisions compound over time.
The Decision Framework
For brands at different volumes, the right tariff strategy looks different:
Under $200,000 annual import volume: Focus on HS code optimization and tariff exclusion tracking. Supply chain restructuring likely doesn’t make financial sense yet.
$200,000-$500,000 annual import volume: Add active customs broker engagement. Explore whether your product structure offers classification opportunities.
$500,000-$2,000,000 annual import volume: Consider supply chain restructuring. The payback period is compelling, and you likely have enough volume to justify the investment.
Above $2,000,000 annual import volume: Engage a trade law firm. Your tariff exposure is significant enough that professional tariff strategy makes clear financial sense.
Practical First Steps
If you’re currently importing LED therapy devices from China and haven’t reviewed your tariff strategy in the past twelve months, here’s where to start:
- Calculate your effective tariff rate as a percentage of landed cost.
- Check whether your current tariff rate is being applied correctly to your specific products.
- Review your purchase agreements: who bears tariff risk, and does the allocation reflect your actual exposure?
- Estimate the cost of supply chain restructuring and compare against projected tariff savings.
The brands that navigate tariffs successfully treat them as a strategic variable, not a fixed cost. That shift in thinking — from compliance mindset to optimization mindset — is where the real opportunity lives.
