The rule we work to: a document goes on this page when it names our company — Dongguan Xinrongfa
New Material Technology Co., Ltd., credit code
91441300MA52TG0L1N — and is currently valid.
Anything held under a former name is shown together with the registration notice that links the names.
Anything not yet issued is marked in progress and is not claimable until we send you the finished file.

The full list — every line, with its real status
| Document | Status | What it actually covers |
|---|---|---|
| Business licence (PRC) |
Current | Dongguan Xinrongfa New Material Technology Co., Ltd. — name, registered address and legal representative
all match this website. Credit code 91441300MA52TG0L1N. |
| Registration notice change of name & address |
2022 | Issued by the Dongguan Administration for Market Regulation on 9 October 2022: the company was renamed from Huizhou Dikang Technology Co., Ltd. It is the same legal entity — the credit code did not change. We send this notice with any certificate that still carries the former name, so the change is explained on paper rather than left to guesswork. |
| ISO 9001:2015 quality management system |
Valid to 23 Jul 2029 | Certificate no. F06726Q02565R053, issued 24 July 2026 by ACM Certification
(CNCA approval no. CNCA-RF-2016-67) under our current company name and credit code.
Certification scope: production of silicone waterproof pads. Phone-case production is covered by our
own in-house QC programme, not by this certificate — we would rather state the scope precisely than let
you assume it is wider than it is. |
| A-level tax credit rating group's first company |
2015 – 2024 | Grade A — the highest rating issued by China's State Taxation Administration — held continuously since 2015 by Shenzhen Dikang Technology Co., Ltd., the group's first company. Publicly verifiable in the national tax-credit database. |
| Material test report RoHS + phthalates |
On file · 2019 | A third-party laboratory report covering Pb, Cd, Hg, Cr(VI), PBB/PBDE and phthalates on our silicone components. Full seven-page report sent on request. It does not cover TPU or PC case bodies — see the line below. |
| RoHS re-test on TPU / PC current case range |
In progress | Samples from the current case range are with a CNAS-accredited laboratory. Not yet claimable — ask us for the current status and we will tell you where it stands. We will not quote a completion date we have not confirmed. |
| High-Tech Enterprise Guangdong province, 2021 |
On file | Awarded by the Guangdong provincial authorities in 2021, under the company's former registered name. The 2022 registration notice above documents that it is the same legal entity, and we send the two together. |
| EU declaration of conformity | Per order | Passive phone cases are not a CE-marked product category, so there is no blanket CE certificate to hand over. We draft a DoC against the specification your market requires, and can add whatever third-party testing that market asks for — quoted as a separate line before you commit. |
| EU responsible person GPSR Art. 4 |
On request | Required for goods placed on the EU market since 13 December 2024. We confirm the responsible-person details in writing for each EU order before shipment. |
| Battery / magnet documentation | Not applicable | Our cases carry no cell, no electronics and no charging circuit. Magnetic variants use passive neodymium elements only, with no power source — so the battery-transport and UN38.3 requirements that apply to powered accessories do not apply here. |
What we deliberately do not claim
Buyer due diligence is a search for what is missing, so it saves everyone time if we name it first.
- No certificate held under a different company's name is presented as ours. Where a document belongs to another entity in the group, it is labelled with that entity and linked to the registration notice.
- No test report is stretched to cover a product it did not test. The 2019 report covers silicone components; the TPU/PC case body is a separate material and is being tested separately.
- No CE mark on passive cases. Cases are not a CE-marked category, and we say so rather than printing a mark that carries no legal basis.
- No certificates we do not hold. If a line is not on this page and not in the list above, we do not have it — ask, and the answer will be the same.
Verify us without asking us
Every claim above can be checked independently, and you should:
ISO 9001:2015 — search certificate F06726Q02565R053 on China's national certification
platform cx.cnca.cn, or on the issuer's own register at acmcert.com.cn.
Company registration — the credit code 91441300MA52TG0L1N is queryable in the National
Enterprise Credit Information Publicity System.
Tax credit rating — Grade A ratings are published in the State Taxation Administration's credit database.
Factory audit — come to Fenggang, Dongguan, or take a live video walk-through of the moulding floor,
printing line and QC bench.
If any check comes back different from what is written here, tell us — we would want to correct the page, not argue about it.
Need a specific document for a tender, a marketplace listing or a customs file?
Tell us which one and what it is for. We send the scan the same day where we hold it, and tell you straight away
where we do not — including whether it can be obtained and roughly what it would take.
