About Dongying Zhizao (东营智造)
Dongying Zhizao is a public bilingual manufacturer directory for Dongying, Shandong, China — not a government portal, not an Alibaba-style marketplace, and not the same as dongying.biz city listings.
What this site is
- A crawlable directory of company profiles, petroleum value-chain categories, API/ISO source-record hubs, and geographic axes (districts, zones, parks, clusters).
- Flagship focus: Oilfield equipment manufacturers in Dongying.
- RFQ desk forms so buyers can send requirements; response targets on forms are operational goals, not contractual SLAs unless separately agreed.
What this site is not
- Not a live certification registry — “Certification records” chips are public archive labels. Verify on the API Composite List.
- Not dongying.biz or municipal government sites — those are separate properties with different purposes.
- Not a claim that listed firms are “verified exporters”; verified count on the home page is whatever the live UI shows (often 0 until a desk process completes).
How to use it
- Read the buyer playbook: How to source oilfield equipment from Dongying.
- Verify API claims: How to verify an API certificate before you RFQ.
