Incoterm (Korea →
Riverside Warehouse)
DDP – Delivered Duty Paid to Chaevi America Warehouse, 2060 Chicago Ave, Unit B-7, Riverside, CA 92507. Chaevi bears all costs and risks of bringing the goods from the factory in Korea to the Riverside warehouse, including export charges, ocean freight, import duties, customs clearance, and inland delivery to the Riverside warehouse. Title and risk of loss transfer to the City of Riverside upon collection from the warehouse.
Buyer Collection (No
Installation)
Where the City of Riverside elects to collect and install the equipment independently, the City shall arrange pick-up from Chaevi's Riverside warehouse at a mutually agreed date and time. No additional delivery charges apply to the City of CHAEVI AMERICA, INC. | COMMERCIAL INVOICE & TOTAL COST PROPOSAL | City of Riverside Chaevi America, Inc. | 2060 Chicago Ave, Unit B-7, Riverside, CA 92507 | (949) 535-6910 | [email protected] | Page 3 of 10 T&C Item Details

Chaevi-Managed
Installation (Delivery to
Site)
Where the City of Riverside requests installation services to be performed by Chaevi or a Chaevi-authorized installation partner, Chaevi shall bear all logistics costs (transportation, handling, and staging) from the Chaevi Riverside warehouse to each designated installation site within the City of Riverside. Site-specific logistics terms will be confirmed in the Installation Services Agreement.
Insurance in Transit
Chaevi shall maintain adequate cargo insurance coverage for all equipment in transit from the factory to the Riverside warehouse. Upon buyer collection from the warehouse, insurance responsibility transfers to the City of Riverside.
Damage During Transit
Any damage to equipment identified upon delivery to the Riverside warehouse shall be documented and reported to Chaevi within ten (10) business days of warehouse receipt. Chaevi shall be responsible for replacement or repair of equipment damaged in transit prior to warehouse delivery.
Force Majeure
(Logistics)
Delays in delivery caused by port congestion, carrier strikes, customs delays, or other events beyond Chaevi's reasonable control shall not constitute a breach of this agreement. Chaevi shall provide prompt written notice and use commercially reasonable efforts to minimize delays.
SECTION B — IMPORT DUTIES, FREIGHT & CUSTOMS (Included in Section A Pricing — For Reference)
IMPORTANT NOTE: All costs listed in Section B are fully absorbed within the all-inclusive unit prices stated in Section A. The City of Riverside will NOT be separately invoiced for any of the items below. Section B is provided for transparency and cost reference only. The breakdown is calculated on the basis of 45 units of 180kW chargers.
FOB KOREA PRICE REFERENCE (180kW Sonic, indicative): If the City of Riverside were to source these chargers on an FOB Port of Busan, Korea basis (buyer responsible for all shipping and import costs), the equivalent factory/FOB unit price for the Sonic 180kW charger would be approximately ~$35,000 per unit. The difference between the FOB Korea price and the delivered DDP price ($40,000) represents the estimated all-in cost of ocean freight, import tariff, customs fees, and inland delivery to the Riverside warehouse (approximately $6,000 per unit for 45 units, as detailed below). This reference applies to the 180kW Sonic model only; pricing for other models is available upon request.

Following the U.S. Supreme Court ruling of Feb. 20, 2026 (striking down the IEEPA tariff), a 10% Section 122 tariff currently applies to Korean-origin goods. Under the KORUS FTA, the base MFN duty rate is 0%; the Section 122 tariff is imposed in addition. Section A unit pricing may be adjusted based on US tariff policy accordingly. Chaevi will notify the 10% × ~$1,575,000

Note Amount
F-
1 California Sales & Use Tax
Chaevi has reviewed California Revenue & Taxation
Code §6381, which generally exempts purchases by
California cities, counties, and other government
entities when the equipment is used in the exercise of
an essential governmental function. Based on Chaevi's
review, the City of Riverside may qualify for this
exemption as a California municipal corporation, which
would result in a $0 California Sales & Use Tax liability on this purchase.
IMPORTANT — City of Riverside Action Required:
Chaevi's review is provided for informational purposes only and does not constitute legal or tax advice. The City of Riverside is strongly advised to independently verify its sales and use tax exemption status with the California Department of Tax and Fee Administration (CDTFA) and/or its legal
counsel prior to finalizing this purchase. If the exemption is applicable, a completed Government Entity Exemption
Certificate (CDTFA Form CDTFA-230) must be provided to
Chaevi prior to invoice finalization.

1. All-Inclusive Pricing: The unit prices in Section A ($40,000 for 180kW; $75,000 for 400kW) are fully all- inclusive delivered prices to Chaevi's Riverside warehouse, incorporating all import duties, ocean freight, customs clearance, and inland delivery costs itemized in Section B. No additional landing or freight charges will be invoiced to the City of Riverside for equipment delivery to the Riverside warehouse.
2. Pricing Validity: Prices are valid exclusively for the City of Riverside project and apply to minimum orders of 45 units. This proposal is valid for 90 days from the invoice date (April 15, 2026). Chaevi reserves the right to revise pricing after the validity period.
3. Minimum Order: The quoted all-inclusive unit price applies to orders of 45 units or more. Orders below this threshold may be subject to revised pricing.
4. Delivery & Logistics: Equipment is delivered DDP to Chaevi's Riverside warehouse. If installation is performed by Chaevi or a Chaevi-authorized partner, Chaevi will bear all logistics costs from the warehouse to each installation site within the City of Riverside, as specified in the Installation Services Agreement.
5. Installation Cost Variability: Section C estimates are based on a 2025 reference project in the Riverside area.
Final costs will vary based on site-specific conditions. A formal on-site engineering assessment by Chaevi's certified engineers is required before final cost confirmation.
6. Import Tariff Notice: The current 10% Section 122 tariff applicable to Korean-origin goods is scheduled to expire approximately July 24, 2026. Should shipment occur after tariff expiration, the Section A unit price may be renegotiated to reflect the reduction. Chaevi will provide advance notice of any such adjustment.
