Trust Signals
Seven certificates, all downloadable here without a form. Each one lists the issuing body and the exact scope it covers, plus a link into that body’s own registry so you can confirm it independently.
ISO 9001, ISO 14001 and ISO 45001 cover our sales and supply operation, certified by a CNCA-accredited body. Read the scope line on each certificate before you rely on it — that is the field procurement checks first.
Every scan opens directly from this page, with the registered entity, certificate number and validity dates as printed. Enough to complete a vendor-onboarding file without waiting on us.
Certifications are strongest when combined with samples, compatibility checks and product-level testing for the real use case.
What Buyers Usually Confirm
A certificate on its own decides nothing. What makes it useful is reading the scope, checking it against the product you actually plan to buy, and pairing it with samples you test on your own reader.
Certificate 98026Q00274R000, valid to June 2029. Scope: the sales service of smart cards and RFID tags — our order handling, specification control and supplier management, audited at least once every 12 months.
Certificates 98026E00200R000 and 98026S00203R000, both valid to June 2029. Environmental and occupational-health systems over the same sales scope — usually what enterprise vendor-compliance forms are asking for.
Issued by Hohenstein Laboratories in Germany for our UHF laundry tag at Product Class II — the class that permits direct skin contact. For anyone tagging garments, linen or wearables this is the strongest independent credential on the page.
Our ISO scope is the sales service of smart cards and RFID tags; production runs on partner lines. If your process needs a certificate covering the production site itself, ask and we will tell you what the partner factory holds rather than let a logo imply it.
Certificate Registry
All certificates are issued to Shenzhen Proud Tek Co., Ltd — RFIDAK is our trading brand — at A2109 Zhantao Science & Technology Building, Minzhi Avenue, Longhua, Shenzhen. Every scan below opens directly, no form and no email. Read the scope line before relying on any of them: the ISO certificates cover our sales operation, while the RoHS, REACH and CE documents are sample-based lab reports on the specific articles they name. "Verify with issuer" opens the issuing body's own registry so you can confirm status without taking our word for it.
Skin-Contact Textile Safety
ScopeUHF laundry tag with RFID chip produced from woven laminated fabric of 100% white polyester with electroconductive yarn and white polyester sewing thread. Product Class II — articles with direct skin contact.
Quality Management System
ScopeSales service of smart cards (PVC cards, wooden cards) and RFID tags. Surveillance audit at least once every 12 months.
Environmental Management System
ScopeEnvironmental management covering the sales service of smart cards (PVC cards, wooden cards) and RFID tags.

EU Restriction of Hazardous Substances
ScopeSample-based conformity assessment of an RFID card against Directive 2011/65/EU and (EU) 2015/863. Covers the tested sample, not the whole catalogue — request testing on your own specification if your compliance file needs it.
EU Chemical Substance Screening
ScopeRFID keyfob screened against 250 substances on the REACH Candidate List; all results below the reporting limit. Sample-based, so it evidences the tested article rather than every SKU.
EU Radio Equipment Directive
ScopeEN 62311 RF exposure assessment of an RFID card, tested 2 to 8 September 2025. CE marking under Directive 2014/53/EU remains a manufacturer declaration supported by reports like this one — it is not a certification issued by a notified body.
Note: All certificate copies are the property of Shenzhen Proud Tek Co., Ltd and are shared for buyer evaluation only. If your procurement workflow requires a fresh stamped copy dated within the last 90 days, request one via the inquiry form below.
Buyer Checklist
Use the checklist below to keep certification review tied to the real project instead of treating it like a generic trust badge.
Open the pages below if supplier validation still needs QC, sample-policy or live-project context.
FAQ
Usually no. Certifications help with supplier screening, but buyers still need to review samples, compatibility, communication quality and production fit for the exact project.
ISO 9001 is the baseline quality-management signal, and ISO 14001 matters when buyers have environmental review requirements. For anything worn against skin — laundry tags, wristbands, uniform labels — OEKO-TEX STANDARD 100 carries more weight than either, because it tests the finished article rather than the management system around it. We hold all three plus ISO 45001; we do not hold an SGS factory audit, so if your process requires one specifically, say so early.
Yes. Product-specific checks such as chip verification, encoding accuracy, material suitability and packaging review are often more important than general supplier certificates once the project moves into sampling.
The best time is during supplier shortlisting or before internal procurement approval, especially if your company has onboarding or vendor-compliance steps.
Share your company's supplier-review requirements and we can point you to the right supporting information for the stage your project is in.
