KATS Adds Green Degradation Field to IC Polymer HS Codes

On July 5, 2026, Korea’s Agency for Technology and Standards (KATS) revised its HS Code Classification Guide for specialty polymers used in integrated circuit packaging, adding a mandatory declaration field for “green degradation rate.” Importers are also required to submit an ISO 14855-2 certification report during customs clearance. This development deserves attention from suppliers of high-end IC packaging materials exporting to South Korea, as well as from import, compliance, logistics, and delivery teams whose timelines may be affected by new documentation requirements.

What the KATS revision changes

According to the provided information, KATS formally revised the HS Code Classification Guide on July 5, 2026. The adjustment applies to specialty polymers used in IC packaging, including materials such as PI, PBO, and BCB. Under the revision, a new mandatory field for “green degradation rate” has been added to the relevant HS code declaration process. At the same time, importers must provide an ISO 14855-2 certification report when completing customs clearance. The stated direct impact is on the compliance pathway and delivery cycle of Chinese suppliers exporting high-end IC packaging materials to the South Korean market.

Where the pressure is likely to appear first

Customs and trade execution may face tighter document coordination

From an industry perspective, direct trading companies and import-export execution teams may be among the first to feel the effect. The reason is straightforward: the rule change is tied to customs declaration fields and supporting certification materials. In practice, the main pressure point is likely to be whether product classification data, supporting reports, and filing documents can move in step without creating clearance delays.

Material suppliers may need to recheck product-level compliance readiness

Analysis shows that suppliers of specialty polymers for IC packaging may need to pay closer attention to how individual product lines are documented for export to South Korea. The likely impact is not only on shipment preparation, but also on internal review of whether existing technical and compliance materials are sufficient for customs use under the updated declaration framework.

Supply chain and delivery planning could become more sensitive to lead-time variation

Observably, supply chain service providers and delivery coordination teams may need to watch for changes in cycle time. The provided information already indicates an effect on delivery schedules. That means booking, customs handover, and customer delivery commitments could all become more sensitive if the required certification package is incomplete or not aligned with the declared HS information.

Downstream buyers may pay more attention to document certainty

For procurement teams and downstream customers sourcing these materials, the immediate issue may be supply assurance rather than product substitution. What deserves closer attention is whether suppliers can provide complete compliance documentation in time, and whether shipment schedules into South Korea remain predictable under the revised clearance requirements.

What companies should focus on now

Watch the exact wording used in customs-facing implementation

Companies involved in Korea-bound shipments should closely review how the new “green degradation rate” field is described and applied in operational documents. The distinction between a formal guide revision and day-to-day customs execution can matter, especially when declarations, supporting paperwork, and product descriptions must match precisely.

Review affected product categories before the next shipment window

For exporters handling PI, PBO, BCB, or related IC packaging polymers, a practical priority is to identify which SKUs, material grades, or shipment batches fall within the revised declaration scope described in the provided information. This is less about broad strategy and more about reducing avoidable clearance friction on active orders.

Check certification availability against shipment timing

The requirement to submit an ISO 14855-2 certification report makes document readiness a near-term operational issue. Companies should compare current report availability with planned delivery schedules and customer commitments, especially where export timing is tight and customs submission windows leave little room for correction.

Align customer communication with compliance status

Suppliers and traders should also pay attention to how they communicate with Korean customers and import-side partners. If documentation timelines, declaration details, or compliance review steps are still being confirmed, that should be reflected clearly in delivery coordination to reduce disputes around lead time and order fulfillment.

Why this looks like more than a one-off filing update

Analysis shows that this development should not be read only as a minor customs formality. Because the new requirement links HS code declaration with a specific certification document, it has practical consequences for how compliance evidence is prepared and synchronized with shipment execution. At the same time, it is still more appropriate to understand this as a rule change whose full business impact will depend on how consistently it is enforced in real transactions. For now, it signals a more document-intensive compliance environment for affected IC packaging materials entering South Korea.

How the industry may need to read this stage

The current signal is clear enough on one point: for affected specialty polymers, customs compliance and delivery planning can no longer be treated as separate steps. A neutral reading is that this is an operationally meaningful change, especially for China-to-Korea supply flows in high-end IC packaging materials. It does not by itself establish broader market outcomes, but it does justify closer monitoring by exporters, importers, and supply chain teams handling these products.
