KATS Revises HS Code for IC Packaging Polymers

On July 3, 2026, the Korea Agency for Technology and Standards (KATS) announced a revision to HS code 2934.99.90 for specialty polymers used in IC packaging. From September 1, 2026, export declarations for the covered materials must include measured biodegradation data certified under ISO 14855-2, reported as % in 180 days. Because the change applies to mainstream packaging materials such as epoxy molding compounds and ABF substrate base materials, it deserves attention from exporters, customs documentation teams, procurement functions, compliance staff, and supply chain partners handling shipments into the Korean market.

What the rule change specifically introduces

The confirmed change is limited but operationally concrete. KATS announced a revision to HS code 2934.99.90, which applies to specialty polymers used for IC packaging. Under the revised requirement, exporters will need to submit measured biodegradation data at the time of export declaration, and that data must be certified under ISO 14855-2. The required reporting unit is % in 180 days, and the obligation becomes mandatory on September 1, 2026.

The event summary also makes clear that the scope includes common packaging material categories such as epoxy molding compounds and ABF substrate base materials. For Chinese exporting companies, the immediate procedural change identified in the input is the need to update customs declaration templates.

Where the practical pressure is likely to appear

Export filing moves from classification alone to data-backed declaration

For direct exporters, the main impact is not only the HS classification itself but the addition of a new declaration element tied to certified test data. Analysis shows this can affect document preparation, internal compliance review, and shipment release readiness. Companies shipping covered polymers will need to pay closer attention to whether the required biodegradation result is available in the correct format before export filing is made.

Material procurement and supplier coordination become more document-sensitive

For procurement teams and manufacturers using epoxy molding compounds or ABF substrate base materials, the change may shift attention upstream to supplier documentation. From an industry perspective, the issue is whether suppliers can provide ISO 14855-2 certified measured biodegradation data in time for export and customs workflows. Even where the physical product does not change, the supporting compliance package now becomes more important to purchasing and scheduling decisions.

Customs, trade operations, and service providers face template and process updates

For customs operations teams and supply chain service providers, the clearest operational change is the reported need to update declaration templates. Observably, that means data fields, document checklists, and handoff procedures may need adjustment before the September 1 effective date. The impact is likely to be concentrated in filing accuracy, completeness checks, and coordination between exporters and agents.

Testing and certification support may become a bottleneck area

For certification-related firms and testing service providers, the new requirement points to a narrower but more immediate task: supporting ISO 14855-2 certification for measured biodegradation performance. Analysis shows the pressure here is less about policy interpretation and more about whether supporting reports can be prepared and aligned with export timing and declaration needs.

What companies should review before the effective date

Check whether covered products are already mapped to the revised code path

Companies dealing in IC packaging polymers should first confirm whether their products fall within the scope described in the event summary, especially where epoxy molding compounds or ABF substrate base materials are involved. What deserves closer attention is product-to-code mapping inside internal trade and ERP documentation, because declaration errors can begin with classification handling rather than testing itself.

Review whether ISO 14855-2 data is available and declaration-ready

Firms should examine whether measured biodegradation data certified under ISO 14855-2 already exists for the relevant materials and whether the result is expressed in the required unit, % in 180 days. Since the input does not provide execution detail beyond the filing requirement, it is more appropriate to treat this as a document-readiness issue that still requires close verification of format and acceptance practice.

Update templates, supporting files, and cross-team handoffs

The event summary explicitly notes that Chinese exporters need to update customs declaration templates. In practice, companies should also review related technical files, product statements, shipment packets, and any internal approval checkpoints linked to export release. Analysis shows this is the kind of change that can create friction if commercial, regulatory, and logistics teams are working from different document versions.

Track follow-on wording and execution signals

The announced rule is clear on the effective date and the required data field, but the input does not provide further detail on implementation wording, review standards, or handling of edge cases. For that reason, companies should continue monitoring subsequent official expressions, customer documentation requests, and any updates to tender or procurement documents that start reflecting the new requirement.

Why this looks like an execution signal rather than a distant policy theme

Observably, this development is not a broad policy discussion but a filing-level compliance change with a stated effective date and a defined reporting requirement. That makes it more appropriate to understand the event as a rule entering practical execution, at least for the products covered by HS code 2934.99.90. At the same time, analysis shows the market still needs to watch how strictly the certification and data format are applied in day-to-day trade operations, because those details often shape the real compliance burden.

From an industry perspective, the notable point is that the rule ties customs declaration more directly to a certified environmental performance metric. Even without adding unverified broader conclusions, this is enough to signal that document quality, traceable test support, and supplier responsiveness may matter more in shipment preparation for covered IC packaging materials.

How the market should read the announcement now

At this stage, the announcement is best read as a confirmed procedural change with immediate relevance for exporters of covered IC packaging polymers, rather than as a general market narrative. The known facts are already sufficient to require preparation in customs templates, certification readiness, and document coordination. The broader commercial effect still needs observation, but the compliance trigger itself has been clearly stated.

A neutral reading is that the change raises the practical importance of certified biodegradation data in export filing for the specified materials. For affected companies, the most reasonable approach is to treat it as an active compliance preparation issue ahead of September 1, while continuing to watch for further clarification in execution practice.

Basis of this article and what still needs verification

This article is based on the user-provided news title, event date, and event summary. The analysis is limited to the confirmed facts provided in that input and does not rely on additional unverified policy numbers, market data, company examples, or source links.

For events of this type, relevant source categories commonly include official announcements, publications from regulatory authorities, customs or trade administration notices, industry association updates, standard organization documents, and reporting by authoritative trade media. A specific official source link was not provided in the input, so the original publication path still needs to be verified on an ongoing basis.

What still requires continued observation includes any further policy detail, certification execution standards, filing interpretation, changes in procurement or tender documentation, market feedback from affected companies, and the practical pace of implementation after the September 1, 2026 effective date.
