As of July 30, 2026, a copper wire entry under four specific tariff classifications does not go into ACE complete without two country fields that were not part of your entry data six weeks ago. One names the country where the copper was smelted. The other names the country where the article was cast. Neither is the country of origin, and in most wire and cable supply chains neither is a question your supplier can answer off the commercial invoice.
The scope is narrow and the consequence is not. Four tariff lines, goods from every country of origin except the United States, and a Section 232 duty assessed on the full customs value of the covered article sitting behind the data. That combination makes these two fields evidentiary rather than statistical. If your entries since July 30 went out with a placeholder, that placeholder is now the work.
What the requirement actually is
CBP set the mechanics out in CSMS #69252300, issued July 15, 2026. Effective July 30, imports of certain copper articles from all countries of origin except the United States must report the primary country of smelt and the country of cast on the entry summary line, and may report a secondary country of smelt where it applies.
Three fields, then, with different weights. The primary country of smelt is required on every covered line. The country of cast is required on every covered line. The secondary country of smelt is optional, and it exists because a caster can blend cathode from more than one smelter.
Four classifications carry the requirement: 8544.42.10, 8544.42.20, 8544.42.90 and 8544.49.10. These are insulated copper wire and cable lines. Nothing else in your entry file is in scope today, which matters, because scope here is set by tariff classification and not by whether you think of yourself as a copper importer.
The data travels through a new field. CBP created Importer's Additional Declaration Type Code 12, Copper Smelt and Cast Country Detail, with the technical instructions in ACE CATAIR Entry Summary Create/Update V109. Your broker needs that mapped on their side before the data you collect has anywhere to go.
The obligation itself is older than the guidance. Proclamation 11021, signed April 2, 2026 under Section 232 of the Trade Expansion Act of 1962 and published April 9 at 91 FR 18201, requires importers to provide CBP the information necessary to identify the countries where the copper used in the manufacture of covered copper article imports is smelted and where those articles are cast. CSMS #69252300 is the plumbing. The proclamation is the duty.
None of this is a new species of requirement. CBP has required countries of smelt and cast on aluminum and its derivatives since it issued guidance on that program years ago, and countries of melt and pour on steel. What changed on July 30 is that copper wire joined them.
The dates that matter
The timeline explains why so many operations are behind, so it is worth walking rather than listing.
April 2 the proclamation was signed. April 3, one day later, CBP issued CSMS #68253075, the duty guidance, which imposed additional duties of 10 to 50 percent on the full customs value of certain steel, aluminum and copper articles and their derivatives from all countries effective April 6, and confirmed that smelt and cast reporting would be required for copper under certain classifications, with a later message to announce when ACE could accept it. April 9 the proclamation published in the Federal Register.
Then three months of quiet, which is the part that did the damage. The obligation existed from April. Only the filing capability was missing. CBP deployed the smelt and cast fields to the ACE certification environment on July 16 and to production on July 30.
An operation that read the April message as a duty notice with a data footnote had a full quarter to go get the answers. An operation that read it as "nothing to file yet" had the same quarter and spent it waiting. Both arrived at July 30. Only one arrived with the data.
Smelt and cast are two different companies
The two fields sound like variations on the same question. In a copper wire supply chain they are usually two different companies in two different countries, and neither is the one that sold you the cable.
Country of smelt points at the smelter that produced the copper, the facility that turned concentrate or scrap into metal. Country of cast points at where the copper article was cast. A typical chain runs cathode from a smelter in one country, cast into rod in a second, then drawn, stranded and insulated in a third. That third country is your supplier and very often your country of origin, and it is the only one of the three that appears anywhere on your commercial documents.
A wire and cable importer we worked with went looking for this data across several thousand part numbers and four suppliers, two in Asia and two in Mexico. The first round of requests came back with the country of origin restated in three cases and no response in the fourth. Not evasion. The suppliers genuinely did not hold it, because they buy rod, not cathode.
The answer lived two tiers up, in the rod mill's cathode purchase records. Reaching it took a direct conversation with the caster, a per-part-number request, and eventually a notification clause written into the supply agreement so that a change of cathode source would not silently invalidate the file. Three weeks of work that could not be compressed, on a data point that has to be present at the moment of entry.
That is the shape of this requirement. It is not a form to fill. It is a sourcing-transparency project with a filing deadline attached, and the filing deadline has passed.
The trap: OTH is permitted, which is exactly the problem
CSMS #69252300 includes a provision that reads like relief. If the primary country of smelt, the secondary country of smelt, or the country of cast are not known, the importer may report "OTH", meaning other.
That is a documented option, not a defect, and for a shipment already on the water it is the right answer. The trap is what happens next, which is nothing. OTH clears the filing. It does not build the file. And it is a formal declaration that you do not know where the metal in your article came from, inside a program whose entire purpose is establishing where the metal came from.
The error dictionary makes the mechanics visible. ACE CATAIR Entry Summary Error Dictionary V51 added five errors for this requirement: a missing primary smelt country code, an unknown-country primary smelt code, an unknown-country secondary smelt code, a missing cast country code, and an unknown-country recent smelt code. Two of the five fire on absence. Three fire on a code the system will not accept.
Read that against the OTH provision and the real exposure separates into two very different failures. An entry that omits the field or carries a code ACE rejects is a broken entry, and you will hear about it the same day. An entry that carries OTH is accepted, liquidates, and tells nobody anything. The first failure is loud and gets fixed. The second is quiet and accumulates.
Common mistake: treating OTH as the steady state. It is a bridge for cargo already in transit, not a sourcing policy. An operation reporting OTH on every covered line in month one and every covered line in month six has not built anything, and it has a documented record of not knowing.
What to do now that July 30 has passed
The preparation window closed. What is left is remediation, in four moves.
Start with what you already filed. Pull every entry summary line submitted on or after July 30 under the four classifications and look at what actually went into those three fields. Sort real country codes from OTH from lines that were rejected and refiled. That distribution is your baseline and it takes an afternoon.
Then map the classifications against your part master, not against your product categories. Scope follows the tariff line, so the question is which of your parts sit on those four numbers, and whether any part is sitting there wrongly or should be there and is not. A misclassification that used to be a rate question is now also a data-obligation question.
Third, put the request upstream in writing and address it past your supplier. Ask the caster, by part number, for the primary country of smelt, the secondary country where cathode is blended, and the country of cast, and ask for a commitment to notify you when a source changes. Verbal answers do not survive a request for information.
Fourth, close the loop with your customs broker on Type Code 12, so the data you collect has a field to land in, and put a monthly review of your OTH percentage on covered lines in front of whoever owns compliance. That single number tracks the whole project.
Quick check: what share of your covered copper lines filed since July 30 carries a real country code rather than OTH? If you cannot answer that today, that number is your first deliverable, and it is yours, not your supplier's.
Across more than 190,000 customs operations a year at 39-plus ports, holding a U.S. Corporate Customs Brokerage License alongside three Patentes Nacionales in Mexico, we have watched this pattern run through steel and then aluminum before arriving at copper. Fields that begin as statistical become evidentiary. The operations that absorbed each transition without disruption were the ones that built the source-country file while the field was still optional, because the data was never the hard part. Reaching the tier that holds it was.
Talk to a Joffroy expert about a smelt and cast readiness review on your covered copper classifications, including the OTH rate on entries you have already filed.
The lasting change is not a new field on a form. It is that the country of smelt now belongs to your purchasing team rather than to your broker, because no one at the border can supply an answer that lives three tiers up your supply chain. From here, a decision to switch cathode sources carries a filing consequence on the same day it is made.
TRADE. UNDER CONTROL.
