Why new capacity is not new supply for years
Qualification attaches to a specific material from a specific plant by a specific route, and until it is granted a working facility is not a source anybody is allowed to buy from.
Pending review

The short version
A separation plant, a sponge plant or a magnet line that is built, commissioned and running is not yet a supplier. In the applications that matter most for these minerals, a buyer may only use material that has been qualified — approved as a specific product, from a specific facility, made by a specific route — and that approval is a separate project with its own timetable. Capacity is the easy half. Why a defence platform cannot simply switch alloys sets out the documents that grant the permission; this article is about what getting into them costs, the one dated instance anyone has published, and why the money arrives last.
Qualification is about a route, not a metal
The distinction that does the work here is between qualifying a material and accepting a batch of it. FAA guidance defines the first as a process "of establishing the database to control an 'original' material system", and the second as the process "of determining, by test and/or inspection, whether a specific batch of material meets the requirements of the applicable procurement specification". One is a standing approval; the other is a routine check against it.
What makes qualification expensive is what it attaches to. The FAA's technical report on the subject records that changes "to the material, process, tooling, and/or facility may require that some (or all) of these tests be repeated" — hedged, may require, but the list is the point. The facility is in it. A qualified material made somewhere else is not, without further work, a qualified material.
The handbook, and what it takes to get into it
For metallic aerospace materials the practical gate is a published handbook of design allowables. FAA policy describes MMPDS as the primary source "for statistically based metallic material properties used for strength approvals made by FAA engineers", and instructs its engineers to consider A and B-basis design values "acceptable for compliance for material strength properties and design values for aircraft certification and continued airworthiness without further showing of compliance".
That sentence is the whole economics of the thing. Material inside the handbook needs no further showing; material outside it needs one, on every programme, for every applicant.
Getting inside is a sampling exercise. A presentation by the MMPDS Program Manager at Battelle on adding a new alloy sets, for A- and B-basis primary tensile properties, 10 heats and 10 lots and 100 tests — "299 for non-parametric" — with reduced requirements for secondary properties, and inclusion in the "next version of MMPDS (yearly)". The document states a burden and a cadence; it does not state a duration, and neither will this article.
A plant produces material. A qualification produces permission. Only one of them can be built with capital.
What it looks like from outside
The consequence is visible in how few places are permitted to supply the most demanding applications: on the US Commerce Department's Section 232 finding on titanium sponge, plants certified for aerospace rotating-quality sponge stood in four countries (commerce_232). Not four countries with sponge plants — four countries with certified sponge plants. That sentence is quoted in full, with the architecture of handbook, qualified-products list and process accreditation that sits behind it, in Why a defence platform cannot simply switch alloys. What that article does not carry, and what this one is for, is how long acquiring the certification takes.
For the duration, the available figures come from an interested party and should be weighed as such. In its Section 232 petition, TIMET stated that it "can take several years for a titanium sponge producer to achieve certification", and described lengthy qualification processes "driven by airframe and engine OEMs" as high barriers to entry. The same submission gives a dated instance: ATI's Rowley plant, "which began production in 2009, did not achieve PQ certification until 2015". A competitor's account of a competitor, filed in a trade case — and the only concrete timeline of its kind located here.
The same structure, a different industry
Nuclear fuel shows the pattern without any of the same commercial framing. The NRC describes lead test assemblies as fuel assemblies "that contain design features or materials that have not been approved for unrestricted use in the reactor core", and explains their purpose: LTA irradiation campaigns "provide knowledge of and experience with irradiated material properties and performance, which is critical for qualifying analytical codes and methods and for developing the design bases to license new fuel material or design features for unrestricted use".
A new cladding alloy, in other words, has to be put into a working reactor under restriction, irradiated, and examined, before it may be used without restriction. No regulator consulted here states how long that takes, so no figure is offered.
Which is why the money arrives last
Put the two halves together and the financing problem writes itself. The IEA describes it directly: downstream customers "typically require demonstrated technical feasibility before committing to long-term offtake, creating a structural mismatch between financing needs and demand certainty". The buyer wants proof the plant works; the plant needs the buyer's commitment to be built.
Public assessments of the timescale reflect that, though they measure something adjacent rather than the same thing: GAO reports DOD's assessment that it can take a decade or longer to establish new domestic sources for rare earths (gao_24), hedged, and about mines and refineries rather than about qualifying a supplier into a platform. That assessment is quoted, and the distinction drawn out, in Why a defence platform cannot simply switch alloys.
So the announcement of a new plant and the arrival of new supply are separated by a process that has no capital cost line and does not appear on a construction schedule. Reading capacity figures as though they were availability figures misses precisely that gap, and the gap is where most of the time goes.
