Certifications & Compliance
The documents we hold are listed below, together with the documents we do not currently hold. Ask us for any item and we will tell you what we have and what we do not.
On file
Credentials and platform status we hold
The third-party credential and the platform status we hold are listed below. Several documents — CE, ISO 9001, brand authorisation letters — we do not currently hold as a company, and we would rather say so up front than send a buyer on a chase.
1. SGS Audited Supplier (Made-in-China.com)
- Audited by: SGS-CSTC Standards Technical Services Co., Ltd.
- Audit report serial: QIP-AS1192382
- Audit date: 2019-05-20
- Scope: site existence, business operations, and the production / quality / export capabilities behind the storefront.
- Status: original scan on file. Current re-audit status is held at Made-in-China.com — ask us if you need the latest status for your supplier file.
2. Alibaba.com Gold Supplier (3rd consecutive year — as of October 2026)
- Status: Alibaba.com Gold Supplier — a verified, paid membership tier on Alibaba.com for the storefront Shenzhen Zhongli Weiye Electromechanical Equipment Co., Ltd.
- Platform standing: 3rd consecutive year of Gold Supplier membership as of October 2026; 3-diamond Supplier Index, 100% response rate and ≤2h response time on the storefront.
- Category ranking: #2 top-selling supplier in Boiler Parts on Alibaba.com (as shown on the storefront, October 2026).
- What it is — and is not: a platform trade status, not a third-party product-compliance certificate (CE / ISO 9001 / etc.). It tells a buyer the storefront is established and responsive on Alibaba.com; it does not by itself evidence product conformity.
What we provide with your quotation
Documents supplied with every quote
Zhongli Weiye is a distributor and system integrator, not a production line. We do not issue our own CE or ISO certificates for the burners we sell — those documents are issued by the original brand. What we do, by default, is include the relevant brand documents with every quotation, on the model you actually receive.
-
Brand datasheet
Full specification sheet from the original brand for the exact model number and revision you receive.
-
Test & inspection report
Factory test / burn-in report for the individual serial number shipped, when the brand issues one for the model.
-
Commercial invoice & packing list
Itemised commercial invoice, packing list and HS code declarations, ready for your customs broker.
-
Warranty card
Serial-linked warranty card with our three-year commitment on quality defects (consumables excluded).
-
Installation & commissioning manual
The brand's installation, commissioning and operating instructions, English edition where the brand publishes one.
If your market needs a CE Declaration of Conformity, an ISO 9001 certificate, or a brand-authorisation letter for a specific model, ask us before you order. We will tell you within one working day what the brand publishes for that model and what we can or cannot supply on top.
Pending / not on file
Documents we do not currently hold
B2B buyers get misled often enough that we would rather draw a clean line. The following items are not on file at Zhongli Weiye today, and we will not invent or back-date them to win an order.
| Document | Status | What we will do if you ask |
|---|---|---|
| CE Declaration of Conformity (company-issued) | Not on file | Supply the brand's per-model DoC when the brand publishes one; we do not issue a Zhongli Weiye company-level declaration. |
| EU Machinery Directive 2006/42/EC attestation | Not on file | Refer you to the brand's compliance documentation for the specific model. |
| EU Low Voltage Directive 2014/35/EU attestation | Not on file | Refer you to the brand's compliance documentation for the specific model. |
| ISO 9001 quality-management certificate | Not on file | Confirm the brand's ISO 9001 status per model; our own internal quality process is not currently certified. |
| Brand authorisation / general-agent letter from each principal | On request | Ask the principal case by case; supply on a per-order basis when the principal authorises it in writing. |
| FDA / FSMA and equivalent sanitary credentials | Not on file | Not applicable to our current burner portfolio; refer food-grade enquiries to the brand's own food-grade lines. |
Buyer Questions
Compliance questions
Can you provide CE documentation for a specific burner model?
If the original brand publishes a Declaration of Conformity for that model, yes — we will include it in the per-model document pack we send with the quote. If the brand does not publish a DoC for the model, we will tell you so and not invent one. We do not issue a Zhongli Weiye company-level CE declaration; we are a distributor, not the legal producer of the equipment.
Are you ISO 9001 certified?
Zhongli Weiye does not currently hold an ISO 9001 certificate. Our internal quality process — pre-dispatch bench testing, three-year warranty, and serial-traceable spare-parts support — is real, but it is not third-party certified. Several of the brands we represent do hold ISO 9001 at their own factories; we can confirm per brand on request.
Are you a verified Gold Supplier on Alibaba.com?
Yes. Shenzhen Zhongli Weiye Electromechanical Equipment Co., Ltd. has held Alibaba.com Gold Supplier status for three consecutive years as of October 2026, with a 3-diamond Supplier Index and a 100% response rate on the storefront. This is a verified platform trade status — it shows the storefront is established and responsive on Alibaba.com, but it is not a product-compliance certificate. Our current third-party compliance credential remains the SGS audit on Made-in-China.com (2019-05-20).
Can you sign a brand-authorisation letter for a specific brand?
Only if the brand principal authorises it in writing, on a case-by-case basis. We do not pre-print or pre-sign such letters. Ask us for the specific brand and the target market and we will come back within one working day with either a signed letter or a clear "no".
Need a specific document before you order?
Tell us the model and the market, and we will tell you what we have and what we do not.
