EXW/FOB vs CIF vs DAP/DDP Incoterms 2020 & Transit Modes for China Clean-Energy Sourcing

Answer-First Verdict: Controlling Landed Cost & Dangerous Goods Risk from Factory Gate to Project Site

Incoterms 2020 Selection (ICC Publication No. 723E): Avoid EXW unless you control a licensed Chinese export agent and bonded consolidation warehouse, as EXW shifts China export customs clearance and factory pick-up onto the buyer . Specify FOB (Shenzhen / Ningbo / Shanghai / Qingdao) when your forwarder holds contracted FCL ocean rates, or CIF / CIP / DAP when you want the seller to bundle carriage and Institute Cargo Clauses (A) marine insurance (0.3–0.5% of CIF) while your local entity acts as Importer of Record (IoR) to recover import VAT/GST . Use DDP only when the seller is equipped to clear destination customs and pay cascading border taxes (such as Senegal's 20% ECOWAS CET DD + 1% UEMOA PCS + 18% TVA or Turkey's import duty + KDV) .

Transit Modes & Lithium Battery DG Rules: Ocean freight under IMO IMDG Code Class 9 (UN 3480) is the standard route for LFP cells (EVE LF304, 5,450 g), rack modules (Pylontech US5000, 39.7 kg; Deye BOS-G, 5.12 kWh), C&I towers (Huawei LUNA2000-215), and 20-ft containers (Sungrow PowerTitan2.0, 5 MWh), taking 7–10 working days (CN → Sri Lanka) or 18–25 days port-to-port (CN → Karachi) . Overland CPEC road freight via Khunjerab/Sost takes 10–14 days door-to-door but closes November–April for winter weather . Air freight (3–5 days airport-to-airport) requires UN 38.3 and IATA DGR Section 4 Packing Instructions 965–970 (Section II / IB marks), restricting practical use to urgent BMS boards, inverter PCBs, or small cell lots .

1. Side-by-Side ICC Incoterms 2020 Cost & Risk Allocation Matrix

Per the landed-cost calculation method, delivered cost builds across four stages: Supplier price, Export and freight, Border, and Destination . Table 1 maps how ICC Incoterms 2020 allocates each stage .

4. Decision Framework: Choosing Incoterms 2020 & Transit Mode

When to Choose FOB vs CIF/CIP

Choose FOB (Shenzhen / Ningbo / Shanghai / Qingdao) when importing multi-container PV or BESS lots where your corporate forwarder controls FCL ocean contracts . Choose CIF or CIP on LCL rack shipments or bonded-warehouse transfers (such as CIP Colombo) so the seller manages China Class 9 DG port handling and bundles Institute Cargo Clauses (A) insurance .

When to Choose DAP vs DDP

Choose DAP (named site/warehouse) when you want door-to-door multimodal transport—including inland oversize BESS haulage—while keeping your local entity as Importer of Record so input VAT/KDV/TVA remains recoverable . Choose DDP only when you require a single duty-paid site price and have confirmed the seller's destination customs brokerage capability .

Five Supplier Checks Before PO Release: Per the Tradvolt landed-cost method, always confirm: (1) Which Incoterm 2020 rule applies and which cost lines are included? (2) Which HS heading (8504.40, 8507.60, 8537.10, 9403.20 / 8538) is declared on the commercial invoice? (3) Who is the Importer of Record? (4) What freight basis (FCL, LCL, overland, air) is assumed? (5) Which destination charges are excluded?
