Verifiable certifications, not just logos

The international standard for quality management systems. It confirms that production — from raw material sourcing to final inspection — follows a documented, consistently applied system rather than ad hoc checks, and that the system is externally audited every year.

Our certificate (No. 29024Q12400-07R0S, to GB/T 19001-2016 idt ISO 9001:2015) registers its scope as the production of nylon cable ties and runs to 29 July 2027. It certifies the system, not any individual product. See our quality control process →

The environmental counterpart to ISO 9001. It certifies that the environmental impacts of production — waste, emissions, energy and material use, and legal compliance — are managed under a documented system that is audited at least once a year.

Certificate No. 29024E11742-07R0S, valid to 19 October 2028. Increasingly a hard requirement in EU and UK tenders and in the supplier questionnaires large distributors send before onboarding.

The occupational health and safety management standard. It certifies that workplace hazards are identified, controlled and reviewed under a documented system — machine guarding, safe working procedures, incident reporting and worker consultation.

Certificate No. 29024S11684-07R0S, to GB/T 45001-2020 idt ISO 45001:2018, valid to 29 July 2027. For buyers running ethical or ESG supplier audits, this is the certificate that answers the labour-conditions question with a third-party document rather than a self-assessment.

UL 62275 is the safety standard for cable ties used in electrical installations. Our certificate covers nylon cable ties as a Recognized Component under file E225194 — UL tested representative samples, and the ties may be used inside end products that are themselves submitted to UL.

A Recognized Component is not the same as a UL Listed end product, and only ties carrying the UL Recognized Component Mark are covered by UL’s Follow-Up Services. If your specification requires UL, ask us to confirm the mark is printed on the exact part number you are ordering. Browse nylon cable ties →

A Constructional Data Form is the technical annex to a TÜV Rheinland certification: it records exactly what was assessed and what the product is declared to do, model by model. Ours (certificate R50557065 0001-0003, dated 23 September 2022) names Wenzhou Difvan Electric as both licence holder and factory — the factory line matters, because it means TÜV assessed the plant that actually makes the ties.

Declared on the form: Type 1 cable tie, non-flame propagating, declared operating temperature for the application −15 °C to 85 °C with a minimum installation temperature of −15 °C, and — usefully for outdoor buyers — resistance to ultraviolet light declared for black ties, not declared for white. If you are specifying for outdoor or UV-exposed use, that single line is the reason to choose black. See UV-resistant zip ties →

Restricts specific hazardous substances in electrical and electronic products: lead, mercury, cadmium and hexavalent chromium, the PBB and PBDE flame retardants, and the four phthalates DEHP, BBP, DBP and DIBP added by Directive (EU) 2015/863.

Our nylon cable ties were tested against all ten by SGS in December 2024 (report NGBPC24007626501) with a stated conclusion of Pass. That is a laboratory result, not a supplier self-declaration.

An EU regulation governing chemical substances in manufactured goods. Our declaration confirms Difvan products do not contain SVHCs above the 0.1% w/w threshold that would trigger notification or communication duties for you as the importer. It is issued per batch or per shipment on request, so the declaration you receive matches the goods you are actually buying.

CE marking indicates a product meets the EU health, safety and environmental requirements of the directives that apply to it, so it can legally be placed on the EEA market. For these product types CE is declared by the manufacturer, supported by third-party test reports rather than by a notified body — which is the correct route.

Cable glands — our current evidence is a Certificate of Compliance from BST Testing (Shenzhen), No. BSTXD190913336509EC dated 15 October 2023, covering models M, G, PG and NPT against the EMC Directive 2014/30/EU and standards EN 61000-6-3, EN 61000-3-2, EN 61000-3-3 and EN 61000-6-1. An earlier declaration for metal glands (test report CNB3110224-00459-E, CTS 2015) remains on file and is listed in the directory above. As BST prints on the certificate, it applies to the tested samples and is not an assessment of whole production.

Terminal blocks — a Certificate of Compliance from ISET S.r.l. (Italy), No. IT1724SC30071817, issued 29 July 2023 and valid to 30 July 2028, against both the Low Voltage Directive 2014/35/EU and the EMC Directive 2014/30/EU. As ISET states on the certificate, the verification is voluntary, a technical construction file is in place, and it does not imply an assessment of production — CE marking and the EC declaration remain the manufacturer’s duty.

SGS is an independent testing, inspection and certification body. An SGS test report is evidence that samples were tested in a third-party laboratory to a named method — it is the document most EU and US buyers accept when they need proof rather than a supplier statement. Ours was issued by the SGS-CSTC Ningbo Branch laboratory and can be authenticated directly with SGS.
