SEMI Sets VOC Cap for Advanced Packaging Materials

On June 21, 2026, SEMI released SEMI G92-0626, a compliance guide focused on environmental and safety requirements for advanced packaging materials. The update draws immediate attention from packaging material suppliers, outsourced assembly and test operations, procurement teams, and cross-border business units because it introduces a defined VOC ceiling for key specialty polymers used in sub-7nm logic SoIC and HBM stacking, with mandatory enforcement in the U.S., Europe, Japan, and South Korea starting in January 2027.

What the New Guide Covers

According to the information provided, SEMI issued SEMI G92-0626, the Advanced Packaging Materials Environmental and Safety Compliance Guide, on June 21, 2026. The guide sets a volatile organic compounds (VOC) limit of no more than 150 ppm for epoxy molding compounds (EMC), underfill, and temporary bonding glue (TBG) used in SoIC and HBM stacking for logic chips below 7nm. The requirement will be mandatorily enforced from January 2027 in the U.S., Europe, Japan, and South Korea. The provided information also states that major Chinese packaging material manufacturers have already started formulation iterations.

Why Different Parts of the Chain Are Watching Closely

Material suppliers face an immediate formulation and compliance question

From an industry perspective, the most direct impact falls on companies supplying EMC, underfill, and TBG. They may be affected because the new rule is tied to the compliance status of the material itself, and the practical impact is likely to show up in formulation adjustment, internal testing, and documentation prepared for customers and regulated markets.

Packaging and manufacturing operations need to reassess incoming material readiness

Packaging manufacturers and related processing operations may be affected at the material qualification and production planning stages. Analysis shows that once a VOC threshold becomes mandatory in major overseas markets, manufacturers handling sub-7nm SoIC and HBM-related production need to pay closer attention to whether current material inputs remain acceptable for customer programs tied to those regions.

Procurement and cross-border business teams will need clearer supply coordination

For procurement teams, traders, and supply-chain service providers, the issue is not only material availability but also whether suppliers can provide timely compliance-related proof for shipments into the U.S., Europe, Japan, and South Korea. What deserves closer attention is the coordination between sourcing cycles, customer confirmation, and market-specific delivery requirements as the January 2027 enforcement date approaches.

Practical Issues Companies Should Track Now

Watch for any further official wording or implementation clarification

Analysis shows that companies should continue tracking how SEMI G92-0626 is referenced in customer requirements and market access practices. The rule in the provided information is clear on the VOC cap and enforcement timing, but businesses still need to distinguish between the published compliance signal and how it is operationalized in contracts, approvals, and shipment review.

Review exposed product lines and destination markets first

What deserves closer attention is whether a company’s EMC, underfill, or TBG products are tied to sub-7nm logic SoIC or HBM stacking programs serving the U.S., European, Japanese, or South Korean markets. This is where the compliance change is most likely to translate into immediate commercial and delivery questions.

Prepare supplier documents and customer communication early

Observably, the operational burden may extend beyond formulation updates. Companies may need to align supplier qualification materials, technical statements, and customer-facing compliance communication so that procurement and delivery teams are not forced to resolve documentation gaps close to the enforcement date.

Separate reformulation progress from shipment readiness

The provided information confirms that major Chinese packaging material manufacturers have started formulation iterations. From a business perspective, this should not automatically be read as full market readiness. Companies should pay attention to the gap between ongoing technical adjustment and actual readiness for customer acceptance, supply continuity, and market-specific execution.

How This Update Is Best Interpreted at This Stage

Analysis shows that this development is more than a routine standards update, because it defines a measurable VOC threshold for specific advanced packaging materials and attaches a clear enforcement timeline in multiple major markets. At the same time, it is more appropriate to understand this as a compliance signal that is already concrete in scope but still requires continued observation in implementation. The rule itself is confirmed in the provided information; the full commercial effect will depend on how suppliers, manufacturers, and customers translate it into qualification, procurement, and delivery decisions over the coming months.

What the Industry Can Reasonably Take From It

At this point, the most balanced reading is that SEMI G92-0626 introduces a targeted compliance change with direct relevance to advanced packaging materials used in leading-edge applications. The immediate significance lies in the VOC limit and the January 2027 enforcement window across four major markets, while the broader industry meaning lies in how quickly material ecosystems can adjust. It is more appropriate to understand this as a near-term operational issue with longer-term signaling value, rather than as a fully settled market outcome.
