Verdict for LFP BESS CN→KH corridor: Tradvolt's bond + transit cycle takes ~14 calendar days from PO confirmation to bond discharge, executed under Incoterms 2020 DAP/CIF. Required instruments: ATA Carnet (issued by an authorised ICC chamber) OR a single-entry bond from a surety, PLUS UN 38.3 test summary, MSDS, commercial invoice, packing list, certificate of origin, and OEM datasheet per SKU. Equipment anchor: CATL EnerC (LFP containerised BESS), BYD MC Cube / HVS/HVM (C&I LFP), Sungrow PowerTitan2.0 (2.5 MW / 5 MWh) and ST2752UX (2,752 kWh liquid-cooled), Huawei LUNA2000-7/14/21-S1 (5–21 kWh residential/C&I), and EVE LF304 prismatic cells (304 Ah). HS codes (8507.60 for Li-ion accumulators, 8504.40 for static converters, 8537.10 for control panels) and Cambodia duties/VAT are PENDING — lookup via the Cambodia General Department of Customs and Excise and the WCO HS Nomenclature 2022 edition before each shipment. Limitation: a fully detailed tariff line is not asserted because Cambodia's national tariff and ASEAN/RCEP preferences are updated periodically. Evidence date: 2026-09-22.
