Can the US Build a DJI? A Teardown of Two DJI Drones
9 hours ago
- In December 2025, the FCC added all foreign-manufactured drones to its 'Covered List,' blocking new models from being sold in the US, with DJI being the primary target due to national security concerns dating back to 2017.
- DJI dominates the global drone market with ~70% share, and its Mini line is especially popular for being under 250 grams, avoiding licensing requirements, and offering fast iteration with seven models shipped between 2019 and 2023.
- Over 90% of drones used by US police and fire departments are DJI, and the California Fire Chiefs Association opposes the ban due to lack of comparable replacements.
- A teardown of the 2019 Mavic Mini and 2023 Mini 4 Pro revealed DJI's hardware margins grew from 72% to 79% between 2019 and 2023, higher than Apple's 53% gross margin on the iPhone 15 Pro Max.
- DJI vertically integrated its supply chain: the share of BOM cost sourced from China rose 28 percentage points from 2019 to 2023, with 22 points driven by in-housing custom silicon, such as the vision SoC, ISP, radio SoC, and core processing SoC in the Mini 4 Pro.
- Custom silicon development is economically viable only at scale; DJI began around 2015 when revenue surpassed $1 billion, following an Apple-like playbook of starting as a system integrator then moving to custom chips.
- DJI optimized for mass, folding flight control into the main SoC, achieving a $139 BOM drone under 250 grams, while competitors using discrete parts often exceed the regulatory weight threshold.
- In some cases, DJI paid more to Chinese suppliers for lighter components, such as battery packs from Ampace offering 38% higher energy density and 20 grams lighter, enabling more sensing and compute hardware.
- DJI stuck with Swiss vendor u-blox for GNSS receivers despite cheaper alternatives, likely due to high switching costs and the mature ecosystem of tools and services.
- US-based Skydio, once DJI's closest competitor, built more intelligent drones with better autonomy but failed on price and mass, losing money on every consumer sale and exiting the market in 2023.
- Skydio's struggle highlights the importance of geographic proximity to the supply chain; DJI's Shenzhen location allows 1-2 day component delivery and rapid iteration, while Skydio faced weeks-long delays.
- The ban's impact is uncertain; no clear US winner has emerged, and similar to the Huawei ban, demand may shift to other foreign incumbents like Samsung, Ericsson, and Nokia rather than domestic manufacturers.
- DJI is fighting the ban legally and lobbying, while US agencies have started adopting Skydio but face a 1.2x-2.2x price premium.
- The article suggests that rebuilding a DJI-equivalent ecosystem in the US requires not just hardware capability but also manufacturing knowledge, talent, and iteration speed that are deeply embedded in Shenzhen's industrial belt.
