2026 Tariff Guide: How Solar Lamp Exporters Benefit From New ASEAN, Japan & South Korea Rules
Leave a message
For anyone importing or exporting solar lamps, 2026 brings significant changes. New tariff reductions under the RCEP (Regional Comprehensive Economic Partnership) agreement took effect on January 1, 2026, further lowering costs for solar lights shipped to key markets.
These changes aren't just trade policy details - they directly impact how much buyers pay and how competitive your products can be in these growing markets.
Here is your practical guide to the 2026 tariff landscape for solar lighting products.
1. RCEP Countries: Lower Rates Across the Board
The most important change for 2026 is the ongoing reduction of tariffs under the RCEP framework -2. This affects trade between major economies including:
Japan
South Korea
ASEAN nations (Thailand, Vietnam, Malaysia, Indonesia, Philippines, Singapore, Brunei, Cambodia, Laos, Myanmar)
Solar Lamp Tariffs: 2025 vs. 2026
| Market | 2025 Rate Range | 2026 Rate Range | Change |
|---|---|---|---|
| ASEAN countries | 5.6% – 14.7% | 2.5% – 13.5% | ↓ 0.5%+ |
| Japan | 5.8% – 16.3% | 3.4% – 13.8% | ↓ 0.6%+ |
| South Korea | 0% – 9% | 0% – 8% | ↓ 0.3%+ |
| Australia & New Zealand | Higher | 2.5% – 15% | ↓ 0.2%+ |
What this means for buyers:
A solar garden light that cost $100 CIF (Cost, Insurance, Freight) to an ASEAN buyer in 2025 would have incurred $5.60–$14.70 in tariffs. In 2026, the same product incurs only $2.50–$13.50 - saving 3–5% on landed cost.
2. Cambodia's New Zero-Tariff Policy for Solar Lamps
Cambodia introduced a significant new policy effective April 1, 2026 -6. Under this reform:
Solar lamps (9 tariff lines) saw import tax reduced from 7% to 0% -3-8
Solar power systems and lithium batteries (179 tariff lines) reduced from 15% to 0% -1-7
Why this matters: As a key ASEAN hub, Cambodia's zero-tariff policy for solar lighting products makes the country more attractive for distribution into the broader ASEAN market. Buyers using Cambodia as an entry point pay no import duty on solar lamps.
💡 Practical tip for buyers:
If you are distributing into Cambodia directly, your solar lamp imports now incur 0% tariff. If using Cambodia as a regional hub under RCEP cumulation rules, you may also benefit from simplified supply chains.
3. Japan: Already Zero for Most Solar Lamps
For solar lamp exporters shipping to Japan, the tariff picture is already extremely favorable.
According to Japan's 2026 tariff schedule, most LED solar lighting products - including garden lights, pathway markers, and photovoltaic lamps - already enjoy 0% import duty under Japan's WTO commitments -9.
Key HS codes for solar lamps (9405 series) show "Free" for general tariff rates -9:
| Product Category | Duty Rate |
|---|---|
| LED solar garden lights | 0% |
| Photovoltaic LED fixtures | 0% |
| Solar-powered lighting strings | 0% |
What this means:
Japan already offers very low or zero tariff access for most solar lighting products. The 2026 RCEP reduction further locks in these favorable rates.
4. South Korea: Stepping Down to 0–8%
For South Korea, 2026 brings continued tariff reductions under RCEP -2-5.
The new range of 0% to 8% means many solar lighting products now enter at or near zero duty, depending on specific HS classifications.
Buyers importing solar lamps into South Korea should check their specific HS code to confirm whether they qualify for the lower end of this range.
5. How Buyers Can Claim These Benefits
To actually benefit from these reduced rates, here's what your customers need to know:
✅ 1. Provide a valid RCEP Certificate of Origin
Without this, standard MFN (Most Favored Nation) rates apply
The certificate proves goods originate from an RCEP member country
✅ 2. Correct HS code classification
Solar lamps generally fall under HS Code 9405.40 (Photovoltaic/ solar lamps)
Verify with your local customs broker before shipping
✅ 3. Work with freight forwarders familiar with RCEP rules
Not all forwarders understand preference claims
Choose partners with experience in the destination country

Final Advice for Solar Lamp Buyers in 2026
If you are importing solar lamps into ASEAN, Japan, or South Korea this year, you are likely paying less in tariffs than ever before - provided you have the correct documentation.
For buyers in markets not covered by RCEP (e.g., some non-member countries), standard MFN rates still apply. Check with your local customs authority for country-specific rates.
The window is open. Make sure your documentation is ready.
