Our Certifications
SHUILIDA holds internationally recognised certifications across quality management and product safety. These are not box-ticking exercises — they govern how every product is made, tested, and shipped.
Product Testing & Standards
Before leaving our factory, every product undergoes rigorous testing. Here are the key tests and standards applied to each product line.
Test reports for any product line are available on request. Third-party lab testing by accredited bodies can be arranged before shipment.
Our Quality Control Process
Five checkpoints between raw material arrival and container loading. Every batch that leaves our facility has passed each gate.
Raw Material Inspection
Every incoming batch of steel, aluminum, brass, and polymer is tested against material certificates. Non-conforming materials are rejected before entering the production line.
In-Process QC
Dedicated QC inspectors check dimensional tolerances, weld integrity, and surface finish at each production stage. Defects are identified and corrected before the next process step.
Finished Product Testing
Every finished unit undergoes a hydraulic pressure test at 1.3 times the rated working pressure. Heat output is spot-checked on radiator batches against EN 442-1 tables.
Pre-Shipment Inspection
A final visual inspection, packaging check, and carton-marking review is completed before loading. Third-party PSI by SGS or Bureau Veritas is available on buyer request.
Certificate Issuance
Each shipment is accompanied by a factory test report, material certificates, and a packing list. CE Declaration of Conformity and ISO certificate copies are supplied on request.

Certification FAQs
Common questions from importers about our certificates, testing, and quality processes.
QDo all products carry CE marking?
Steel panel radiators, aluminum radiators, and brass ball valves carry CE marking. Underfloor heating systems and PPR pipes comply with the relevant EN standards but are sold under technical documentation rather than a full CE declaration. Contact us for specific product compliance documentation.
QCan I get a copy of your ISO 9001 certificate?
Yes. Email sales@shuilida-hvac.com with your company name and we will send the current certificate within 24 hours. Our ISO 9001 scope covers all product lines listed on this website.
QWhat happens if products fail at destination?
All products undergo factory pressure testing before shipment. In the event of a quality issue at destination, we investigate using shipping photos, test reports, and batch records. Replacements or credit notes are issued for confirmed manufacturing defects within 12 months of shipment.
QAre your factories open for audit?
Yes. We welcome unannounced or scheduled factory audits from buyers and third-party inspection agencies. Contact our export team to schedule a visit.
QDo you offer products certified for the US/Canadian market?
Currently our certifications target European (CE) and international (ISO) markets. US/Canadian specific certifications (NSF, UL, CSA) are available on OEM orders with sufficient volume. Contact us to discuss requirements.
QWhat is your product warranty period?
Steel panel radiators: 10-year warranty against manufacturing defects. Brass ball valves: 5-year warranty. PPR pipes and underfloor heating: 10-year warranty on materials. All warranties are subject to correct installation and operating conditions.
Our export team can provide any documentation your customs or procurement team requires.
