Vietnam Requires VIEP Certification for RO Antiscalants

On June 13, 2026, Vietnam’s Ministry of Industry and Trade and Ministry of Environment jointly issued Circular No. 28/2026/TT-BCT, introducing a new compliance threshold for imported industrial water-treatment chemicals. From October 1, 2026, imported RO antiscalants and biocides must obtain Vietnam Industrial Eco-Products (VIEP) green formulation certification before customs clearance. For exporters, importers, procurement teams, and supply-chain service providers, this is not just a product standard update; it directly affects certification timing, shipment planning, and market access.

What the new entry requirement confirms

The confirmed change is that Vietnam has linked market access for imported RO antiscalants and biocides to VIEP green formulation certification under the newly issued circular. The certification focus includes biodegradation of phosphorus-based components at or above 85%, organophosphonate residue at or below 0.5 mg/L, and heavy metal migration. The measure was jointly issued on June 13, 2026, and is scheduled to take effect on October 1, 2026. The information provided also states that the average certification cycle for Chinese exporters is 45 days, and products without certification will not be allowed to clear customs.

Where the pressure will likely appear first in the supply chain

Export shipments now face a pre-clearance compliance gate

From an industry perspective, exporters of RO antiscalants and biocides are likely to feel the most immediate impact because certification becomes a condition tied directly to customs clearance. This means product readiness is no longer only a matter of commercial agreement or routine shipping documentation; certification status may affect whether goods can enter the market at all. What deserves closer attention is the alignment between testing results, technical files, and shipment schedules, especially where delivery windows are already tight.

Importers and procurement teams may need to reset ordering timelines

Importers and buyers in Vietnam may need to pay closer attention to lead times, because the stated average 45-day certification period for Chinese exporters introduces a planning factor ahead of October 1, 2026. Analysis shows that procurement decisions may increasingly depend on whether suppliers can demonstrate certification progress, supporting test records, and readiness for the new threshold values. In practical terms, purchase timing and supplier selection could become more compliance-sensitive than before.

Testing and certification-related service links become more critical

For companies involved in compliance support, laboratory testing, document preparation, or certification coordination, the rule change points to a more central role in transaction execution. Observably, the required checks on phosphorus-based biodegradation, organophosphonate residue, and heavy metal migration mean that technical verification is closely tied to trade continuity. Even where the detailed execution pathway is not yet described in the input, businesses in these service links will likely be judged by their ability to support complete and usable certification submissions.

What companies should watch before the October deadline

Review whether product formulations map to the stated thresholds

Analysis shows that exporters and suppliers should first compare existing product data against the listed certification focus items: phosphorus-based component biodegradation, organophosphonate residue, and heavy metal migration. This is not yet a conclusion about pass or fail outcomes, but it is a practical starting point for identifying whether current formulations and supporting data are likely to face added scrutiny.

Check whether trade documents and technical files are certification-ready

What deserves closer attention is whether product dossiers, test reports, and technical documentation can support a VIEP certification process without delaying delivery. Since uncertified products will be barred from customs clearance after the effective date, any mismatch between commercial paperwork and compliance documentation could become a trade risk rather than a routine administrative issue.

Reassess delivery schedules against the stated 45-day certification cycle

From an industry perspective, the stated average certification cycle for Chinese exporters suggests that contract execution, shipment booking, and replenishment planning may need earlier coordination. This should be understood as a planning observation, not as proof of a fixed outcome for every case, because actual execution details and review pace are not further described in the input.

Track how the rule is reflected in market-facing documents

Companies should also watch for how the new requirement may later appear in procurement specifications, tender documents, supplier qualification reviews, and customs-related compliance checks. The current information confirms the certification mandate and the effective date, but it does not provide full operational detail, so follow-up attention remains necessary.

Why this looks like an execution signal, not just a policy notice

Observably, this development is more appropriate to understand as an implemented market-entry requirement with a defined effective date rather than a general policy direction. The reason is straightforward: the rule identifies covered product categories, names the certification route, sets specific testing focus areas, and ties non-compliance to denial of customs clearance. At the same time, analysis shows that the market still needs to watch how certification review standards, documentary expectations, and trade-side enforcement are applied in practice.

How to read the current significance of this change

At this stage, the update should be read as a concrete compliance change affecting access to the Vietnam market for imported RO antiscalants and biocides. It does not yet justify broad conclusions beyond the facts provided, but it clearly signals that certification readiness, timing control, and technical documentation will matter more in upcoming transactions. A neutral reading is that this is already a rule change with direct trade implications, while the finer points of implementation still require continued observation.
