Procurement language around drone components overlaps in ways that trip up even careful buyers: a part can be made in the USA and not NDAA-compliant, NDAA-compliant and not made in the USA, and on the Blue UAS Framework without being either. These are the terms that come up, each read for what it means for a propeller.
| Term | What it means for a propeller |
|---|---|
| NDAA covered-country requirements | Federal agencies may not buy or operate UAS or their components from covered foreign entities, and the restriction flows down through contracts, grants and cooperative agreements to the component level. A propeller from a covered-country maker, or molded from covered-country material, fails it. The explainer covers the mechanics. |
| NDAA-compliant | A component whose manufacturer is not a covered entity, whose supply chain contains no covered-entity material or sub-component at any tier, and whose maker can document both. It is a statement about the chain, not the label. |
| Made in the USA | A country-of-origin claim about where the part is manufactured. Under the FTC's standard an unqualified claim means all or virtually all of the product is made here. It says nothing by itself about whether a sub-tier supplier is a covered entity. |
| Country of origin | Where a part was manufactured or last substantially transformed. It is the fact that customs, tariff and procurement rules all key on, and for a molded propeller it turns on where the molding happened and what went into the mold. |
| ASDA / FASC list | The American Security Drone Act, implemented through FAR 52.240-1, prohibits delivering or operating UAS from covered foreign entities listed by the Federal Acquisition Security Council on SAM.gov. The Drone Dominance framework requires an 'ASDA-compliant entity' as its Phase 2 floor. |
| Section 889 | The FY2019 NDAA telecommunications prohibition on certain Chinese-made equipment. The framework requires 'no Section 889 components' in flight controllers, radios, GNSS and other electronics; it is not a propeller rule but it sits on the same BOM. |
| Blue UAS Cleared List | Complete aircraft vetted for DoD use. Being on it is a statement about the aircraft as configured, not a certification of each component in isolation. |
| Blue UAS Framework | Components — flight controllers, radios, GNSS, ESCs, cameras, Remote ID — vetted for use in building cleared aircraft. It carries no propeller entry; see the Blue UAS and Drone Dominance piece. |
| Drone Dominance supply-chain framework | DoD's component-by-component sourcing schedule for its small-UAS program, dated 23 July 2026, with dated phases through August 2027. Not a statute; it governs participation in that program. Row 10 is propellers, airframe and structural components. |
| Non-covered country (NCC) | The framework's term for any country that is not a covered country — principally not China. NCC assembly, NCC fabrication and NCC materials are its recurring requirements. |
| DFARS specialty metals and magnets | Domestic-melt requirements for specialty metals (10 USC 4863) and, under DFARS 252.225-7052, restrictions on magnets, tantalum and tungsten from China, North Korea, Russia and Iran. They reach a propeller only through fasteners and hardware; they reach a motor through its magnets. |
| Berry Amendment | A domestic-source requirement for certain DoD purchases. The framework invokes it for fasteners at Phase 3 preferred; it is not a propeller-material rule. |
| Buy American Act | A federal preference for domestic end products in direct federal purchases, tested on where the item is manufactured and the share of domestic component cost. Distinct from NDAA covered-country rules, which are prohibitions rather than preferences. |
| Trade Agreements Act (TAA) | For certain federal purchases, requires a product to be made or substantially transformed in the United States or a designated country. A TAA-compliant part can still contain covered-country material, so it does not substitute for NDAA documentation. |
| FCC Covered List | The FCC's list of equipment that cannot receive new equipment authorizations. In December 2025 it added foreign-produced UAS and UAS critical components; the published critical-components list names motors and batteries among others, does not name propellers, and is described as non-exhaustive. See the Covered List explainer. |
| Section 232 tariff | The August 2026 proclamation placing tariffs on imported UAS and components. Propellers and rotors sit in Annex III at 25 %, effective 9 February 2027 — see the tariff article. |
| Drop-in | In the Anvil line, a size referenced to a specific foreign part on diameter, pitch, blade count and hub, read from that manufacturer's published listing, so a platform keeps its tune when the supplier changes. A match on the three numbers alone is labelled a nominal match, not a drop-in. |
Two habits keep these straight. Treat "made in the USA" as the start of the conversation, not the end of it, and ask every supplier — domestic or not — for the sub-tier documentation that turns a label into evidence.
