10. Key Considerations (Honest Note)
Premium Tier Pricing — BYD prices at the top of the Chinese supplier range; volume and brand-equity commitments expected for the best terms.
Capacity Allocation — As the #1 global integrator, BYD allocates 2026 capacity primarily to mega-projects (>500 MWh). Smaller buyers should engage early to secure slots.
MOQ & Engineering Support — Standard MOQ is higher than mid-tier suppliers (e.g., Great Power, REPT, Hithium); custom engineering support typically requires confirmed orders.
Geopolitical Exposure — As a Chinese state-listed champion, BYD products may face higher scrutiny in U.S. utility procurement; EU and emerging markets remain fully open.
Trademark Caution — "BYD" is a registered global brand. Do not co-brand or rebrand without written authorization.
