Derui
Liquid Silicone
LSR and plastic injection moulding with in-house tooling from Panyu, Guangzhou — manufacturing and export scope confirmed, 10 insured staff, ISO 13485 and a medical cleanroom declared but not independently sighted.
Liquid silicone, from tool to part.
Liquid Silicone Rubber (LSR) Parts
Custom parts made by LSR injection moulding — the company’s stated core process. Specify silicone grade (general, food-contact or medical), Shore hardness, colour, tolerances and the standard the material must meet.
Medical-Use Silicone Components
Silicone accessories for medical supplies are listed among the company’s products. Medical-use rubber and plastic product manufacturing is in the registered scope; there is no medical-device production licence in scope. Buyers of regulated devices should confirm who holds the device registration and ask for ISO 13485 evidence.
Maternal & Baby Silicone Products
Silicone items for baby and maternity use are listed as a customer segment; baby-product wholesale and retail are in scope. Food-contact and child-safety testing (e.g. FDA 21 CFR 177.2600, LFGB, EN 14350) has to be requested per product.
Protective Masks & Seals
Silicone protective masks, diving-mask parts, bathroom accessories and automotive seal parts are named among customer products. Provide drawings or samples with operating temperature, medium and fit requirements.
Plastic Injection-Moulded Parts
Plastic injection moulding is offered alongside LSR; daily-use and medical-use plastic product manufacturing are in scope. State resin, finish, tolerances and annual volume.
LSR & Plastic Injection Moulds
Mould manufacturing is in the registered scope, and the company lists LSR injection moulds among its main products. State cavity count, expected shot life and whether the buyer or the factory will own the tool.
What the registry confirms, and what stays open.
A Moulder Registered in 2018
Registered on 2018-04-02 in Guangzhou, the company’s scope covers daily-use plastic products, rubber parts, daily-use and medical-use rubber products, medical-use plastic products, metal daily goods and moulds. The registered industry is rubber and plastic products. The registered address is a factory building unit in Shilou Town, Panyu.
Export in Scope
Import and export of goods and of technology are in the registered scope, so the company can contract and invoice exports in its own name.
A Small Workshop by Headcount
The record shows 10 social-insurance contributors and RMB 1 million registered capital; paid-in capital is not published. The company’s own listing describes a 2,000 m² plant with 20 LSR injection machines, 5 plastic injection machines and 20+ mould-making machines — not independently checked.
Medical-Grade Claims, Declared
The company states ISO 13485 and a Class 100,000 (ISO 8 equivalent) medical cleanroom. Neither the certificate nor the cleanroom has been sighted in this check. Medical-use product manufacturing is in scope; no medical-device production licence is.
High-Tech Enterprise Tag
Chinese enterprise records tag the company as a High-Tech Enterprise (高新技术企业); the certificate number and validity date were not sighted. Twelve patents are declared; the patent list has not been checked.
Clean Risk Record, Frequent Changes
No self, related or historical risk items on record (no abnormal operation, penalty, enforcement, dishonesty or litigation). Eleven warning items: four investor changes, four key-personnel changes and three registered-address changes.
What was checked — and what the check found.
The stamp rests on a confirmed registration of a limited-liability company with rubber and plastic manufacturing (including medical-use products) and export in scope, and no risk items on record. What stays open: ISO 13485, the cleanroom, the High-Tech Enterprise certificate and twelve patents are declared but none has been sighted; the company’s B2B listing ticks about forty management-system certifications, which should be read as ticked boxes rather than held certificates; it describes more than twenty years of LSR experience against a 2018 registration; and its listing address in Shilou Town differs from the registered one. What would close it: the ISO 13485 certificate with scope and certification body, the patent numbers, the High-Tech certificate, and a note on which address the moulding lines run at.

Is it a manufacturer?
Yes. Its registered scope covers daily-use plastic products, rubber parts, daily-use and medical-use rubber products, medical-use plastic products and moulds, and its registered industry is rubber and plastic products. The record shows 10 insured staff.
Can it export directly?
Yes. Import and export of goods and technology are in its registered scope.
Can it make medical devices?
Its scope covers medical-use rubber and plastic products and non-licensed medical-device trading; there is no medical-device production licence in scope. For a regulated device, the brand owner normally holds the registration and the supplier works under its quality system. Ask for the ISO 13485 certificate and its scope.
Is ISO 13485 confirmed?
No. ISO 13485 is declared by the company but the certificate was not sighted at listing. Its B2B storefront also ticks about forty other management systems (IATF 16949, BRC, HACCP, FSC and more); treat these as ticked boxes until a certificate with number, scope and certification body is provided.
What LSR material standards should I ask about?
For food and baby contact: FDA 21 CFR 177.2600 in the US and EU Regulation 1935/2004 with LFGB or equivalent testing in Europe. For medical-contact parts: ISO 10993 biocompatibility and USP Class VI data for the specific silicone grade. These are properties of the grade and the process, so ask for reports tied to your part.
Why does the listing say 20+ years if it was registered in 2018?
The B2B storefront claims more than twenty years of LSR experience; the company was registered on 2018-04-02. The experience may belong to the founders or a predecessor business, but this is not explained. The storefront address in Shilou Town also differs from the registered address.
