1. Identifying the Right HS Codes (Duty Savings)
Correct HS Code classification is the first step to minimizing import costs. Wrong classification can lead to delays, fines, or higher duty rates.
GaN & Car Chargers (HS 8504.40)
Most wall and car chargers fall under 'Static Converters.' In many regions, this category enjoys lower duty rates compared to complex electronics. We help you choose the correct classification to optimize your duty rate.
Power Banks (HS 8507.60)
Lithium-ion batteries have specific classifications. Correct labeling as 'Portable Power' can prevent your shipment from being flagged as 'Loose Batteries,' which are restricted. We provide MSDS and UN38.3 documentation for smooth clearance.
Wireless Chargers (HS 8504.40 or 8543.70)
Depending on the country, these may be classified as power adapters or radio-frequency devices. We help you choose the most compliant code to avoid customs issues.
Engineering Insight: Always request official HS classification documents from your supplier. WOWOHCOOL provides signed HS Code certificates with every export shipment, verified by our logistics partners.

Note: Rates are estimates and may vary based on specific product classifications. Consult your customs broker for accurate rates.
3. Shipping Factors: The "Weight vs. Volume" Rule
Shipping costs depend on actual weight vs. volumetric weight. Understanding this can significantly reduce your per-unit landed cost.
GaN Chargers: Compact Packaging Advantage
GaN technology allows for smaller packaging. This means you can fit 30% more units in a standard shipping carton compared to old silicon chargers, effectively lowering your shipping cost per unit. For a 65W GaN charger, typical volumetric weight is only 0.3kg per unit.
Power Banks: Dangerous Goods Considerations
As Dangerous Goods (DG), power banks require specialized sea or air freight. We optimize the inner packaging to meet UN38.3 standards while keeping the volumetric weight as low as possible. Average volumetric weight: 0.4-0.6kg per 10000mAh power bank.
4. The 2-in-1 Advantage: Simplified Logistics
Our Hybrid 2-in-1 (GaN + Power Bank) devices are classified under the battery category (HS 8507.60). Importing one hybrid SKU is often more cost-effective in terms of customs entry fees than importing a charger and a power bank separately.

Popular Hybrid Models for Export
- • WOP69 - 65W GaN + 15000mAh Power Bank (2-in-1)
- • WOP67 - 45W GaN + 10000mAh with Built-in Cable
Example: 5,000 Wireless Chargers
Key Takeaway
Adding just $0.27 per unit to your product cost covers all shipping and import fees. Always factor this into your pricing strategy to maintain profit margins.
