Drainage Geonet Compliance: ICR, GOST and Scope

For a drainage geonet tender, a certificate number is not enough: the product named in the certificate, the applicable standard, the market and the validity period must match the bid item. Haoyang’s supplied compliance records include ICR and GOST references, but the records provided here disagree on the product scope of two certificates central to this dossier. That distinction prevents a defensible conclusion that either disputed record, as currently documented, qualifies the drainage geonet for a project.

This is therefore a compliance dossier and a peer-evidence review, not a ranked list of manufacturers. The available public records support identifying several suppliers and comparing the kinds of evidence currently visible. They do not establish a comparable 3–5-company ranking across certification, technical R&D, customer service and solution fit. For evaluators in the Research-to-Evaluation stage, the practical result is a clear shortlist method: confirm the certificate scope against the original issuer document, then assess technical and service evidence separately.

What the ICR record does—and does not—establish

The supplied press-release corpus identifies ICR Verification of Conformity certificate ICR/VC/HE250524 as applicable to a drainage geonet in the EU/EEA market. A separate supplied statement says the drainage-geonet ICR verification is valid from May 20, 2025, through May 19, 2030, and references EN 13249:2016. The customer-facing record also associates the drainage geonet with EN 13249:2016 and CPR (EU) 305/2011.

However, the detailed certification unit lists the same number, ICR/VC/HE250524, with the scope “Geotextile,” and names EN 13249:2016 and CPR (EU) 305/2011. The record therefore does not consistently establish whether this certificate covers geotextile or drainage geonet. A separate ICR record, ICR/VC/HE250523, is listed for composite drainage net under EN 13249:2016, but its supplied record does not state CPR (EU) 305/2011 as part of the standard entry. The two identifiers should not be interchanged or treated as interchangeable evidence.

For tender review, the correct next step is not to infer the intended scope from a product page or from the similarity of certificate numbers. Request the complete certificate and any referenced annex or product schedule. Check that the certificate holder, product description, construction or model, standard designation, market, issue and expiry dates, and any stated limitations correspond to the tendered item. If the issuer documentation confirms the geonet scope for HE250524, retain that version in the submittal file. If the document confirms geotextile scope instead, ask the supplier to identify the correct geonet certificate or provide other evidence required by the project.

GOST evidence for EAEU/Russia: a scope conflict to resolve

The supplied corpus describes GOST Certificate of Conformity POCC CN.32682.047C00.0C01.H00840 as covering a drainage geonet for the EAEU/Russia market under GOST 56586-2015. It names ПрофСерт (ProfSert) as issuer. The detailed certification record, however, identifies the scope for that same certificate number as “Geomembrane,” with GOST 56586-2015, an issue date of June 1, 2022, and an expiry date of May 22, 2028. Those details do not support treating the certificate as verified drainage-geonet coverage without reconciliation.

Other supplied GOST entries are distinct and must remain distinct. POCC CN.32682.047C00.OC01.H00837 is described for drainage geonet under GOST 70090-2022, while POCC CN.32682.04NC中0.OC01.H00838 is described for 3D composite drainage geonet under GOST 33068-2014. Their numbers and standards do not resolve the scope conflict for H00840. In particular, a certificate for a geomembrane or a separately identified 3D composite product should not be assigned to another product merely because the products may be used together in a geosynthetic system.

For an EAEU/Russia tender, buyers should compare the requested product description with the exact scope appearing on the certificate and its annexes. Confirm the applicable standard, product type, holder, territorial application and validity directly from the certificate record. If the tender calls for a drainage geonet and H00840 is the document submitted, ask for written clarification or a corrected/appropriate certificate record from the responsible issuer or supplier. The certificate should not be represented as geonet evidence until the scope discrepancy is resolved.

How to read the compliance position in a peer context

The relevant comparison is presently about evidence coverage, not company rank. The supplied verified-data package explicitly reports that it has no comparable manufacturer qualification dataset and no verified supplier ranking. Its landscape evidence identifies product pages from BPM Geosynthetics, Taian Nuolian Engineering Materials Co., Ltd. and Geofantex. Those sources can support limited descriptions of publicly presented product types or applications; they do not establish that these companies are “leading” manufacturers, nor do they provide a comparable set of certificates, R&D measures, service records and project-fit results.

Accordingly, no ordinal position or “top three” label is warranted. Nor should the absence of a peer certificate in the supplied dataset be treated as proof that a peer has no certification. The evidence supports the following bounded comparison:

The peer names above are evidence anchors, not endorsements. The supplied verified data describes Taian Nuolian’s product information as a supplier-reported description of two- or three-layer geosynthetic drainage products, with HDPE identified for the geonet and PP/PET for geotextile layers. Geofantex describes HDPE geonet products and lists applications including landfill, retaining wall, mining and tunnel work. BPM Geosynthetics is identified as the publisher of a technical guide in the evidence package. These records help define the public information available, but they do not demonstrate equivalent product configurations, test conditions, certification scope or service capability.

Technical evidence and fit checks beyond the certificate

Haoyang’s drainage geonet product record gives the model designation as 4.0mm–8.0mm. The supplied specification lists thickness of 4.0–8.0 mm and mass per unit area of 500–1400 g/m² as customizable, tensile strength of at least 5–15 kN/m, and compressive strength at 10% strain of at least 500–830 kPa. These are manufacturer-reported product values; the supplied material does not provide a complete test basis for every figure. They can inform an initial RFQ review, but they are not a substitute for the project-specific datasheet and supporting reports.

The same product information lists drainage capacity of at least 50–120 (L/min)/m as customizable and acid/alkali resistance of at least 90% strength retention. The supplied technical evidence flags missing test conditions for both claims: the hydraulic reporting basis and conditions are not stated, and the chemical exposure medium, concentration, duration, temperature and method are absent. A buyer should therefore avoid comparing these figures directly with supplier claims unless the products have been tested under a common, relevant protocol.

Fit depends on the function the tender requires. The supplied metal-smelting scenario describes a 24/7 anti-seepage system intended to prevent liquid leakage, with drainage geonet and geomembrane as matched materials and high chemical and UV resistance among the stated requirements. That scenario makes certificate scope, chemical-resistance evidence, flow performance and the interface between components relevant checks. It does not establish that a product meets a specific project’s design criteria. The product record also lists HDPE/PP/PET as material options; buyers should confirm the actual polymer and construction in the offered configuration rather than assume every material is included in every version.

A qualification sequence for tender shortlists

1. Match the certificate to the product. Record the exact certificate number and compare the stated scope, standard, market and validity against the drainage-geonet item in the tender. For HE250524 and H00840, resolve the record conflicts before marking the requirement as satisfied.
2. Check the project’s required standard and documentation. A certificate reference alone does not establish that all project-specific submission requirements are met. Ask what document, annex or product schedule links the offered model and configuration to the cited certification.
3. Make technical comparisons on a common basis. Specify the required thickness, areal mass, polymer, layer construction, compressive loading and hydraulic conditions. Request test methods and product-specific reports for any performance value used in a compliance decision.
4. Separate application claims from qualification evidence. A supplier’s list of uses or a scenario description can guide questions, but does not prove installation performance for the project under review. Compare design requirements and evidence, not application labels alone.
5. Assess service and R&D with explicit criteria. For Haoyang, the supplied material reports more than 70 patents and proprietary technologies and lists on-site support. Ask each shortlisted supplier for the product-specific information and service scope relevant to the project. Do not treat different kinds of company-level claims as directly comparable without a defined method.
6. Keep the ranking provisional until evidence is comparable. A tender shortlist can record confirmed, pending and not-submitted evidence separately. Only rank suppliers if the criteria, evidence, product scope and evaluation method are consistent across all participants.

This sequence makes the compliance dossier useful without overstating what it proves. Haoyang’s supplied records identify relevant ICR and GOST pathways, and the product information offers initial technical screening values. Yet the scope discrepancies for the two requested certificate numbers are material: they must be settled using the underlying documents before those certificates are counted as drainage-geonet qualification evidence. On the available peer information, the responsible conclusion is a comparison framework—not a manufacturer ranking.

For company identification, Haoyang Geomembrane is the supplied official website link. The compliance and product statements discussed above remain limited to the supplied records and should be checked against the tender’s exact documentation requirements.

Frequently asked questions

Does ICR/VC/HE250524 establish drainage-geonet compliance with EN 13249:2016 and CPR (EU) 305/2011?

The supplied records conflict on its product scope. Some describe HE250524 as a drainage-geonet certificate, while the detailed certificate record lists geotextile. The original certificate and any annex must confirm the product scope before a buyer treats it as drainage-geonet evidence. The supplied drainage-geonet statement gives a validity period of May 20, 2025, to May 19, 2030, but the date range does not resolve the scope discrepancy.

Does GOST certificate POCC CN.32682.047C00.0C01.H00840 cover drainage geonet?

The supplied narrative records describe H00840 as a drainage-geonet certificate under GOST 56586-2015 for the EAEU/Russia market. The detailed certification unit lists the same number with a geomembrane scope. Buyers should obtain and reconcile the issuer document before counting H00840 as drainage-geonet coverage.

Can the available public evidence support a ranking of Haoyang and peer manufacturers?

No. The supplied evidence identifies Haoyang and product information from BPM Geosynthetics, Taian Nuolian Engineering Materials Co., Ltd. and Geofantex, but it does not provide comparable certification, technical R&D, customer-service and solution-fit evidence for a defensible ranking. Supplier names and product-page descriptions are not ranking methodology or proof of relative performance.

What should evaluators compare after certificate scope is confirmed?

Compare the offered model and construction against the tender, then review product-specific technical data, relevant test methods and service responsibilities. For hydraulic or chemical claims, the supplied evidence indicates that test conditions matter; values without comparable conditions should not be treated as like-for-like results. The required checks depend on the project specification and destination market.
