A copper products company in the Bajío spent three years importing without a single padrón problem. Cathodes in, wire rod out to the domestic market, every registration current, every renewal diaried. Then a buyer in Texas asked for a quote on semi-finished bar, and the compliance lead pulled the company's registrations to confirm there was nothing to do before booking the truck. There was nothing to do on the import side. The export side did not exist.
That is not an unusual file. It is the predictable result of a mental model in which a padrón sectorial is an import control, something the authority uses to decide what comes into the country. For gold, silver and copper the register that actually bites points the other way, and the operations that get caught are usually the ones with the cleanest import compliance, because a clean import file is exactly what makes a team stop looking.
The register lives on the export side
Anexo 10 of the Reglas Generales de Comercio Exterior for 2026, published in the DOF on January 14, 2026, splits the sectoral register into two. Fracción I is the Padrón de Importadores de Sectores Específicos. Fracción II is the Padrón de Exportadores Sectorial. Gold, silver and copper appear once, in fracción II, as Sector 9, "Oro, plata y cobre."
The negative check matters as much as the positive one. There is no precious metals sector anywhere in fracción I. The two metals sectors on the import side, Sector 14 "Siderúrgico" and Sector 15 "Productos siderúrgicos," run through the iron and steel headings and do not reach Chapter 74 at all. Nothing in the import register asks a question about gold, silver or copper. A company can hold every import registration the law contemplates for its product mix and still be unable to file a single export pedimento on the same metal.
What sits inside Sector 9 is broader than the sector name suggests. It covers copper from the earliest stage forward: copper ores and concentrates, mattes and cement copper, unrefined copper and anodes, cathodes, waste and scrap, bars, wire, plates and foil. On the precious metals side it covers silver and gold in powder, unwrought and semi-manufactured form, plated stock, ash containing precious metal, jewelry components such as clasps and continuous chain in lengths of ten meters or more, and coins without legal tender status. It also covers platinum waste and scrap, under a heading the sector name never mentions.
The practical consequence is that the trigger is the fraction, not the business description. A jewelry manufacturer, a refiner, a mining company and a scrap consolidator can all land in Sector 9, and a company that thinks of itself as a copper fabricator rather than a metals exporter lands there the moment the goods cross out.
What Sector 9 actually asks for
Enrollment runs through Article 87 of the Reglamento de la Ley Aduanera, in its text as reformed on February 23, 2026, and through regla 1.3.7, using the A6 form and ficha de trámite 141/LA published in the DOF on January 12, 2026.
The baseline conditions apply to every sector on the export side and are worth reading as a set, because they are checked at the moment of resolution rather than at the moment of filing: an active RFC, a valid e.firma, current compliance with tax obligations, a fiscal domicile with "Localizado" status, a buzón tributario (the SAT's electronic mailbox) in "Validado" status, absence from the SAT listings under Articles 69 and 69-B of the Código Fiscal de la Federación, and no resolution under Article 49 Bis determining that the company issues false invoices. The authority also verifies that the opinión de cumplimiento, the SAT's certificate of tax compliance standing, is positive not only for the company but for its shareholders and legal representatives.
On top of that baseline, Sector 9 carries two specific requirements, and they tell you what the register is really for.
The first is corporate: a copy of the notarial instrument containing the company's incorporation, together with proof of its inscription in the corresponding Registro Público de Comercio, the public commercial registry.
The second is a provenance statement. The legal representative signs, under oath, a declaration setting out the date and the origin of the gold, silver or copper product, and attaches the corporate name and RFC of the company's principal suppliers of the finished or semi-finished goods to be exported.
That second requirement is the whole design of the register in one paragraph. Sector 9 is not a volume control or a tariff mechanism. It is a traceability instrument, and it asks the exporter to put its supply chain on the record before the first shipment, not after an audit. Operations that buy metal through brokers, aggregators or informal channels discover at this step that they cannot name their suppliers in a document they are willing to sign.
The scrap trap
Copper waste and scrap sits inside Sector 9, so the instinct is that it follows the same path as primary metal. It does not.
Common mistake: treating copper scrap as a Sector 9 filing like any other. Ficha 141/LA provides that exports under NICO 7404.00.03 01, 02 and 99 must additionally satisfy the requirements set for sectors 10 through 15. Two documents becomes a full corporate file.
Those additional requirements are substantial. The applicant must submit, as a plain text file, the complete list of current shareholders, partners, associates and legal representatives with valid RFC keys, all registered and active, and the shareholders must be current under the dividend income regime of Title IV, Chapter VIII of the Ley del Impuesto sobre la Renta. Shareholders resident abroad who are not required to register in the RFC are handled through their own separate filing. The applicant must also submit a signed statement describing the industrial use of the goods, meaning the economic and technical activity that transforms the raw material into other products, along with the productive processes the exported goods undergo.
Read together, the two tiers are a deliberate design. Primary and semi-finished metal is asked where it came from. Scrap is asked who owns the company and what the material is actually for. Anyone who has watched how scrap flows move across the corridor will recognize why the second question exists.
The operational consequence is a sequencing problem. A metals company that exports both primary product and scrap needs the heavier file, and needs it assembled before it applies, because the shareholder and dividend regime status of individual partners is not something a compliance team can fix in the week a purchase order lands.
Ten days, and what happens when the answer is no
Ficha 141/LA sets the maximum period for the SAT to resolve at ten days. Read alone, that number makes the registration look like a short errand. Read alongside the rest of the ficha, it does not.
The same document marks as not applicable both the maximum period for the SAT to request additional information and the maximum period for the applicant to answer such a request. There is no stage for requesting additional information. The filing is either complete or it is not.
Resolution is also published rather than notified. Results appear in the SAT's Padrón de Importadores y Exportadores portal, in the "Consulta resultados del Padrón de Exportadores" section, under "Procedentes" when the registration goes through and under "Improcedentes" with the detected inconsistencies when it does not. A rejected application is not corrected in place. Ficha 141/LA is explicit that the applicant must resolve the observed inconsistencies and file again under regla 1.3.7.
So the honest answer to how long the registration takes is ten days per attempt, with each rejection restarting the ten days rather than pausing them. A company that submits an incomplete supplier statement, or that files while a shareholder's RFC status is inactive, is not ten days from exporting. It is ten days from finding out, plus however long the underlying problem takes to fix, plus another ten.
And there is no relief valve at the border. Article 86 of the Reglamento allows a one time authorization to clear goods already held in depósito ante la aduana, in customs custody at the port of entry, for parties that have not completed registration or that are suspended, but by its own terms it reaches only those obliged to register in the Padrón de Importadores. The export side has no equivalent. A metals shipment that reaches the crossing without Sector 9 does not get an exception. It waits.
Where it touches the general padrón, and your broker's file
Two connections are easy to miss because they run in different directions.
The first is upward. Article 87 does not require a Padrón de Importadores registration in order to enroll in the Padrón de Exportadores Sectorial. A pure exporter can register. But ficha 141/LA provides that enrollment will not proceed when the applicant is suspended in the Padrón de Importadores under Article 84 of the Reglamento or regla 1.3.3. You do not need the import register to get in. You do need it not to be broken. For a company that imports cathodes and exports wire, a suspension on the import side closes both directions at once.
The second connection runs sideways, into the file your broker keeps on you. Regla 1.4.14 of the RGCE, as reformed in the DOF on May 14, 2026, requires the customs broker to maintain an electronic file on every user requesting foreign trade operations, refreshed every three years or whenever the user reports a change. That file screens for the same things ficha 141/LA screens for: the Article 69-B listing, the Article 49 Bis false invoice resolution, fiscal standing and identity of the legal representative. It also asks the user to describe, under oath and with photographs, the premises and equipment used in the operation.
In our work across 39 ports and more than 190,000 customs operations a year, we see the same file requested twice, by the authority and by the broker, and assembled twice by teams that did not realize it was the same file. Building it once, and keeping it current in one place, removes a recurring month of work and removes the risk that the two versions say different things about the same company.
The export registration itself has no expiry. Ficha 141/LA marks its validity period as not applicable. What it has instead is a set of conditions that must remain true, which is a different and more demanding thing than a renewal date. A registration obtained in March and a shareholder who goes inactive in September produce the same practical result as an expired document, with no calendar reminder to warn you.
Do the registration before you quote, not after
The sequence that fails is the common one: win the order, book the truck, then discover the register. The sequence that works inverts it. Before a metals operation quotes its first export, someone should be able to answer three things in writing. Which fractions the shipment will actually declare. Whether any of them fall under NICO 7404.00.03, because that answer changes the size of the file. And whether every condition in ficha 141/LA is currently true for the company, its shareholders and its legal representatives, not true in principle but true today, in the SAT's records.
If that takes a week, it is a week spent before there is a customer waiting. Spent afterward, it is the same week with a purchase order aging on top of it.
