OVERVIEW
Importing Batteries, Accumulators & Energy Storage from South Korea
Importing batteries from South Korea into the United States carries low compliance risk, with an effective duty rate of 0% KORUS FTA; IRA-compliant under US-Korea FTA. A Section 232 Tariff Rate Quota (TRQ) arrangement applies: steel and aluminum products within quota limits may enter at reduced or zero Section 232 duty, while above-quota imports face the full 25% surcharge.
Batteries imported from South Korea to the United States is subject to CBP entry requirements, applicable HTS-based duty rates, and agency compliance clearances. This guide covers the complete import process for 2026.

COMPLIANCE — DOT / EPA / CPSC / UL/NRTL
US Compliance Requirements for Batteries Imports
Regardless of origin country, batteries imports must satisfy the following US regulatory requirements before or at the time of CBP entry filing:
- DOT hazardous materials regulations (49 CFR 173.185) — lithium batteries classified as Class 9 hazmat; UN 38.3 testing certification mandatory
- UL 2054 (household batteries) or UL 2580 (EV batteries) safety certification required by most US retailers and OEMs
- EPA Mercury-Containing and Rechargeable Battery Management Act compliance — labeling requirements for rechargeable batteries
- CPSC recall authority for consumer batteries posing fire/explosion risk — robust quality control documentation increasingly expected

South Korea is a top-3 global battery manufacturer (LG Energy Solution, Samsung SDI, SK On). Korean battery firms have major US gigafactory investments.
What compliance agencies regulate batteries imports from South Korea?
Batteries imports require compliance with: DOT, EPA, CPSC, UL/NRTL. Specific requirements include: DOT hazardous materials regulations (49 CFR 173.185) — lithium batteries classified as Class 9 hazmat; UN 38.3 testing certification mandatory and UL 2054 (household batteries) or UL 2580 (EV batteries) safety certification required by most US retailers and OEMs.
What documents are required to import batteries from South Korea?
Required documents include: Commercial Invoice with battery chemistry, capacity (Wh), and cell configuration; Packing List with DOT hazmat shipping classification; Bill of Lading or Airway Bill with DG (Dangerous Goods) declaration; UN 38.3 Test Summary (mandatory for all lithium battery shipments). Additional: UL or NRTL safety certification documentation; Country of Origin Declaration. Ensure all documents are prepared before the shipment departs South Korea.
How long does customs clearance take for batteries from South Korea?
Typical timeline: 25–45 days (ocean; DG surcharges and routing restrictions); 3–7 days (air with DG acceptance). CBP clearance typically takes 1–3 business days for compliant entries. Complex entries (AD/CVD, formal entry review, or examination) may require 5–15 additional business days.
Are there Section 301 or Section 232 tariffs on batteries from South Korea?
No Section 301 tariffs apply to South Korea-origin goods. Section 232 applies with a TRQ arrangement — steel within quota enters at reduced/zero Section 232; above quota faces 25%.
What DOT and hazardous materials regulations apply to lithium battery imports?
Lithium batteries are classified as hazardous materials under DOT 49 CFR Part 173.185. Requirements include: UN certification of battery cells (UN 3090 lithium metal, UN 3480 lithium-ion), state-of-charge limits (lithium-ion cells ≤30% for air transport), proper packaging meeting UN specifications, hazmat labeling and markings, and shipping papers with Emergency Response information. IATA (air) and IMDG (ocean) regulations apply to international shipments. Non-compliant lithium battery shipments are rejected by carriers and subject to DOT penalties up to $82,012 per violation.
What are the HTS codes and Section 301 duty implications for battery imports from China?
Batteries fall primarily under HTS 8506 (primary batteries) and 8507 (electric accumulators/rechargeable). Lithium-ion batteries (8507.60): 3.4% MFN base + 25% Section 301 for Chinese-origin batteries (List 3). Lead-acid batteries (8507.10): 3.5% MFN + 25% Section 301 from China. The effective duty on Chinese lithium-ion batteries is approximately 28.4%. This has driven major US battery importers to diversify sourcing to South Korea (Samsung SDI, LG Energy Solution) and Japan (Panasonic, TDK) — which face no Section 301 — as well as India and Vietnam where manufacturing is expanding.
What UL certification and CPSC requirements apply to consumer battery-powered products?
Consumer products containing lithium batteries require: (1) UL 2054 certification for stand-alone batteries and UL certifications for the end device (e.g., UL 1642 for lithium cells, UL 62368-1 for IT/AV equipment), (2) CPSC oversight — numerous lithium battery recalls have occurred for overheating/fire risk; CPSC requires that battery products meet applicable UL standards, (3) FCC certification for devices with wireless functionality, (4) California Proposition 65 labeling for certain battery chemistries. CPSC actively screens consumer electronics imports for non-certified batteries at US ports.
What does the KORUS FTA cover and how do I claim preferential treatment?
The US-Korea Free Trade Agreement (KORUS, effective 2012) has phased out duties on the vast majority of US-Korea trade — most goods now enter at 0%. To claim KORUS preference, have a valid origin certification from the Korean exporter (self-certification is permitted under KORUS). Goods must meet KORUS rules of origin requiring sufficient production in the US or Korea, with country-specific RVC or tariff shift rules by HTS code.
Are Korean electronics (Samsung, LG, SK Hynix) subject to any additional US tariffs?
No. South Korea is not subject to Section 301 tariffs. Section 232 TRQ applies to Korean steel and aluminum, not electronics. Korean electronics benefit from both KORUS FTA (0%) and the ITA (0% WTO multilateral rate), providing dual zero-rating. Major Korean brands have extensive US operations that further simplify compliance for distributors and importers.
How strictly does CBP enforce KORUS rules of origin for auto parts?
CBP has significantly increased KORUS auto parts origin verification, particularly for vehicles and major components. Importers should obtain detailed origin certifications from Korean suppliers including net cost calculations and production records. Korean auto parts manufacturers supplying global OEMs typically maintain robust KORUS documentation — request it proactively rather than waiting for a CBP CF-28 inquiry.
