Alloy and origin certificate files, assembled from mill and plant records for your quality manager.

A customer's PO asks for certs, maybe a country of origin line, sometimes a finish report. Someone in quality chases the billet or mill record for the cast number, the press lot and tensile result, and the finishing line's record, then types up a certificate and a cover note.

In the test, AI works from copies of those records for shipments you already closed and builds the file for each load, every field traced back to the record it came from: alloy and temper, heat or lot, test values, chemistry, finish, and smelt and cast where a record states them. What it can't find goes on the missing list and stays blank. Your reviewer, the quality manager or the person who knows these files best, holds each draft against the certificate that actually shipped.

Lot numbers have to connect. ASTM B666, the practice for marking aluminum products, lists what goes on a wrought product or its tags: the company name or trademark, alloy and temper, the basic specification number, ordered dimensions for some forms and a lot number, and it leaves package marking out. Your billet supplier's cast number, your press lot and the finishing rack or batch can each sit on a different sheet. The draft ties them together through whatever record connects them and lists any link it can't find.

Tests and chemistry are fields until a spec gives them meaning. ASTM B221, the specification for extruded bars, rods, wire, profiles and tubes, expects tensile strength, yield strength and elongation to conform and notes that elongation doesn't apply below certain sizes. The Aluminum Association's Teal Sheets, its registration record for wrought alloy composition, gives a limit for each element, then other elements each and in total, and says only limits identical to a registered designation belong to that designation. It warns that local, national or international rules can tighten a composition further and advises writing those into the sales agreement, so a customer's added chemistry line becomes a question. The draft copies what your mill or lab reported and never decides that a result passes.

Importers are asked where the metal began. U.S. Customs and Border Protection's March 7, 2025 guidance has importers report ISO country codes for primary smelt, secondary smelt and most recent cast on Section 232 aluminum goods. It says goods made only from recycled aluminum report a secondary smelt in the country of origin, importers must be able to provide manufacturing documents on request, and goods of U.S. origin are not covered by that reporting. A message dated June 13, 2025, effective June 28, lets filers report UN for unknown on derivative imports, with an extra heading required. An April 3, 2026 message tells filers to keep reporting these countries for subject aluminum and derivatives. So a customer that imports, or buys from one that does, can ask for those lines, and the draft fills them only from a record that states them.

Cast is its own record. Commerce's import licensing rule, 19 CFR 361.103, published December 23, 2020, defines the country of smelt as where new metal is made from alumina and the country of most recent cast as where the metal was last melted and cast solid, a billet or ingot included. A license application may say not applicable for the primary smelt field when only secondary aluminum was used, but it may not say unknown or not applicable for cast. That is why a billet supplier's certificate can answer one line and leave another open. We date these because trade rules change often, and they appear here as background: this page is not legal, customs or engineering advice, and the draft makes no customs determination.

A finish record has its own codes. Michigan State University's storefront standard writes clear anodize as AA-M12C22A41, Class I, 0.018 mm or thicker, under AAMA 611. The University of Texas at Arlington writes AA-M10C21A41, Color #14 Clear, 0.7 mil. Albuquerque Public Schools calls for a clear Class II finish, AA-M12C22A31, 0.4 mil minimum, and Maryland's June 2013 sections list AA-M12C22A42/A44. AAMA 611-26, announced in February 2026, covers anodic coatings on architectural extrusions and panels, batch or continuous coil. The draft carries the code, class and thickness reading your finish record shows and lists any mismatch for your quality manager, who checks it against the certificate that shipped.

With a yes, each new shipment gets the same file for about 30 days.

Your quality manager reviews and releases every certificate, and nothing goes to a customer or a broker unless a person sends it. The live month is scored on the same table.
