Public-source supplier profile · independent editorial note
What does Filtersun Filter (Dongguan) Co., Ltd. publicly disclose, and what must a buyer still verify?
Filtersun Filter (Dongguan) Co., Ltd. states on its own website that it completed a signing on 28 August 2026 and took up residency at the Shanghai International Auto Parts Permanent Exhibition Hall, and that it received a council-member plaque from a Yangtze River Delta aftermarket production-and-marketing alliance. The company also describes itself as a filtration manufacturer with more than twenty years in the sector and three production bases. All of that is the company’s own account; it is not an independent qualification of the company, its certificates, its capacity or its export readiness.
What this page does—and does not—establish
This is an independent profile compiled from publicly accessible materials. It is not an endorsement, a supplier certification, a quotation, a stock or capacity statement, or a statement of official affiliation between this site and the company. A public product list, a company’s own quality-system statement, a project event mention or a selection announcement does not establish that any product conforms to the requirements of your market, that a certificate is current, that a production site is covered, or that the company will contract with you on any particular terms. Confirm every commercial and compliance point directly with the company before you order.

The “relationship” line above records how the company or the cited source describes the connection. It is deliberately not converted into a stronger claim: a company’s own selection announcement, a reported plan to display, and a named representative at a project event are three different things, and none of them is a supplier qualification.
What the cited public sources report
- Public residency statement. The company states that on 28 August 2026 it completed a signing and took up residency at the Shanghai International Auto Parts Permanent Exhibition Hall, and received a council-member plaque from a Yangtze River Delta automotive aftermarket production-and-marketing alliance.
- Public production footprint. The company states that it operates three production bases: Dongguan in Guangdong, Suqian in Jiangsu and Dawu in Hubei.
- Public product range. The company lists filtration products spanning construction machinery, heavy trucks, agricultural machinery, mining equipment, generator sets and passenger-car cockpit applications.
- Public capability statement. The company says it covers independent research and development, tooling development, precision manufacturing, full-item testing and main-engine supply in-house.
- Public export contact. The company publishes a dedicated export desk with email, messaging-app contacts and telephone numbers for filtration enquiries.
Each item above restates what the cited source publishes. These are not findings by this site, and they have not been independently audited. Where a statement comes from the company itself, it is attributed to the company; where it comes from a project or event report, it is attributed to that report.

A published product list describes what a company presents publicly. It does not confirm that any listed item is currently in production, in stock, dimensionally suitable for a specific vehicle, or available under your market’s requirements.
Certification and quality statements
No current certificate evidence was reviewed for this public profile. The company describes a standardised laboratory testing regime covering fatigue, airtightness, resistance, efficiency and physicochemical performance. That is a self-description of internal testing, not a certificate, and no management-system certificate was reviewed.
Where a company states a management-system certification, ask for the certificate itself: its current validity date, its scope, the certified legal entity and the specific production site. A group-level or historical certificate frequently does not cover the part, the site or the period you are buying from.
What an overseas buyer still needs to verify
- Confirm which legal entity and which of the three stated production bases would contract and supply your order.
- Request current test reports and any management-system certificate for the specific filter reference and the specific production site.
- Confirm filter media specification, filtration efficiency, burst and collapse pressure ratings, and dimensional fitment against your OE reference.
- Confirm MOQ, tooling ownership, packaging, lead time, Incoterms and export documentation directly with the company.
These are procurement verification prompts, not legal, customs, certification or product-safety advice. Importers should obtain specialist advice where their market requires it.
Commercial and logistics position
- Minimum order
- Buyer qualification required
- Lead time
- Buyer qualification required
- Export markets
- Export markets not established by the reviewed sources. The company publishes an export desk, which indicates export activity, but no destination markets are stated on the reviewed pages.
- Stated location
- Dongguan, Guangdong — with additional stated bases in Suqian, Jiangsu and Dawu, Hubei
- Export capability
- The company publishes a dedicated export desk and messaging-app contacts. Confirm product-specific regulatory and commercial readiness directly with the company.
No item in this table is a quotation or a commitment. Where a field reads “buyer qualification required”, it means the reviewed public sources do not establish the figure at all — the only way to obtain it is to ask the company directly for your specific part and volume.
