1. Errors that repeat across agreements
China-Korea and ChAFTA certificates share a set of failure patterns, mostly because the documents look similar and get treated as interchangeable.
They are not. Each agreement has its own certificate format, its own origin criterion code set, and its own staging schedule.
2. Using the wrong certificate
The most basic error. A Form E presented for Korea-bound goods, or a China-Korea certificate presented for Australia-bound goods, confers nothing.
Both destination authorities accept only the certificate issued under the agreement being claimed. The formats are visually distinguishable, and an incorrect format is caught immediately.
This error usually originates upstream, when the buyer says “send the certificate of origin” and the supplier reaches for whichever template is open.
3. Copying origin criterion codes between agreements
Each agreement uses its own code system for the origin criterion field. The codes are not harmonized.
An exporter who files China-Korea and ChAFTA certificates for similar products will be tempted to reuse the code. The result is a certificate carrying a code that does not exist in that agreement’s system, or that means something different.
This produces either an immediate rejection or, worse, a certificate that passes issuance and fails at verification.
4. Using last year’s rate
Both agreements phase tariffs down on 1 January each year.
Cost calculations built on last year’s rate produce a quote that is wrong in the customer’s favour or yours. Neither is good, but the second is discovered at the invoice stage, which is later and worse.
Check the rate at the start of each year for the products you ship regularly. This takes an hour and prevents a year of small mispricing.
5. Origin criterion inconsistent with the product
The filed criterion does not match the product’s pre-assessment, or the product cannot satisfy the criterion filed.
The mechanism is template reuse. The previous shipment’s certificate is copied, the raw material source changed three months ago, and nobody updated the criterion.
The certificate issues. It is wrong. It is discovered at verification.
6. FOB used where CIF is required, and the reverse
Regional value content calculations go wrong in two directions.
Using a CIF value as the denominator understates the percentage and can make a qualifying product appear not to qualify.
Using purchase prices rather than CIF values for imported materials overstates the percentage and makes a non-qualifying product appear to qualify.
The second is more dangerous because it passes internal review. The issuing authority recalculates and the figure falls.
7. Transport documentation gaps
Both agreements require direct transport or qualifying transit.
Goods routed through a third country need documentary evidence that they remained under customs control and were not entered into trade or consumption.
A through bill of lading is the usual evidence. Where the shipment was consolidated or re-handled at a hub, additional records may be needed.
The failure mode is not the transit itself. It is the absence of a documented chain when the question is asked.
8. Goods description too general
Descriptions like “spare parts” or “electronic components” do not let the destination authority map the goods into its national tariff schedule.
Korea’s schedule is finely subdivided. Australia’s is less so but still requires a description that identifies the goods.
A description that names the material, function, and relevant specification solves this at the filing stage.
9. Consignee field problems in third-party trade
Where an intermediary sits between the Chinese exporter and the destination buyer, the consignee field needs to be completed consistently with the actual transaction and with the bill of lading.
A certificate naming an intermediary while the bill of lading names the final buyer, with nothing linking them, invites a query.
10. A pre-filing check that covers all of the above
Before filing either certificate, confirm:
The certificate format matches the destination.
The origin criterion code belongs to that agreement’s system and reflects a current determination.
The regional value content calculation, if used, applies the correct valuations.
The HS code’s first six digits match the export declaration.
The goods description is specific enough for the destination schedule.
The consignee reconciles with the bill of lading and the commercial documents.
The transport route is supported by documentation.
Ten checks. Most failures are one of these.
11. Closing view
The errors on this list are not subtle. They are the kind that survive because the filing process is routine and nobody treats each certificate as a fresh determination.
The discipline that prevents them is unglamorous: check the rate each January, and never copy an origin criterion without confirming the product still matches it.
