Plain-language guides to the regulations reshaping drone component sourcing — NDAA covered-country requirements, the FCC Covered List, and what component-level compliance actually requires.
The Blue UAS Cleared List, the Blue UAS Framework and DoD's Drone Dominance supply-chain framework, separated — with the propeller row of the framework quoted in full and its February 2027 and August 2027 dates.
Motors, ESCs, flight controllers, radios, GNSS, batteries, cameras, propellers: what NDAA covered-country rules require of each line, where the Pentagon's Drone Dominance supply-chain framework goes further and by when, what to ask a supplier, and examples of non-covered-country sources.
A definitions page for drone-component procurement: NDAA covered-country rules, ASDA, Section 889, Blue UAS, the Drone Dominance framework, DFARS, Berry, Buy American, TAA, the FCC Covered List and Section 232 — each read for what it means for a propeller.
Propellers and rotors sit in Annex III of the August 2026 Section 232 proclamation — 25% ad valorem, effective February 9, 2027. What the tariff covers, what it doesn't, and why the date matters more than the number.
The two materials small-UAS propellers are molded from, what each does under impact and under load, why folding blades are glass-fiber nylon, and which sizes in the line use which — with material following application, not size.
How to read 5×4.3×3, why 5 and 5.1 are different sizes, what pitch and blade count change, what CW and CCW mean, bullnose versus pointed tips, and why the hub is the fourth number a drop-in has to match.
What NDAA compliance means for a drone propeller, why the foreign-made parts most platforms were designed around are the problem, how to vet a domestic drop-in replacement, and how to spec one into your program.
NDAA covered-country and flow-down requirements restrict federal purchase and operation of covered foreign UAS — including individual components like propellers. What that means for programs, primes, and suppliers.
Additions to the FCC Covered List and expanding NDAA covered-country requirements keep tightening restrictions on foreign-made UAS components. What's changing and what to do.
A procurement checklist for component-level NDAA compliance: the four requirements a propeller must meet, the sub-tier supply-chain trap, and the questions to ask any supplier.
The sourcing question, answered brand by brand for the foreign propellers most often found on US drone platforms.
