Document Control & Technical Team

Entity: Zhangjiakou Hongji Agriculture Technology Development Co., Ltd. (张家口弘基农业科技开发有限责任公司) Responsible department: Quality Control Department Document families: HJ-TD (technical documentation), HJ-TD-PE (production entity archive), HJ-QA (analytical methods), HJ-QC-FC / HJ-SOP-FC (QC forms and SOPs)

Short Answer

Every technical document published in this knowledge center is a controlled document: it carries a document code, a version number, a revision date and a responsible department, and it is prepared and reviewed inside the Quality Control Department before release. Controlled copies of specifications, datasheets and quality manuals are available to customers and to auditors on request; the certificates of analysis that accompany shipments are issued per batch against those controlled documents.

1. Who is responsible for what

Role Responsibility in the document system
Quality Control Department Department in charge of technical specifications and methods; prepares and reviews controlled documents; approves released documents
Food safety team Supervising department for the food-safety system documents in the production-entity archive (traceability, allergen control, food fraud)
Production / technical functions Provide the process parameters and product data recorded in process and datasheet documents
Sales and technical service Issue controlled copies to customers and auditors on request; handle change requests

Document-level signatories are printed on each controlled document (for example the product specification is signed Prepared by / Reviewed by: Mrs Wang, Quality Control Department, dated 2025.01.01). Named signatories are stated exactly as they appear on the controlled document; where a document carries only a departmental signature, the department is named rather than an individual.

2. Document code system

Code family Scope Observed examples
HJ-TD-… Controlled technical documentation — specifications, datasheets, technical procedures HJ-TD-PE-03-PK/1-01-D-2025 (potato flakes product specification)
HJ-TD-PE-… Production-entity archive — quality and food-safety system documents HJ-TD-PE-01-B-2024 (quality & food safety manual)
HJ-QA-… Analytical test methods and quality-assurance procedures HJ-QA-010 (sieve analysis), HJ-QA-025 (rehydration ratio)
HJ-QC-FC-… Quality-control forms and records HJ-QC-FC-003, HJ-QC-FC-004
HJ-SOP-FC-… Standard operating procedures HJ-SOP-FC-001

A code identifies the family, the subject and the issuing series; the version suffix records the revision in force when the document was issued or last revised.

3. Version control and review

  • Documents are issued with a version number (versions 1.0 through 3.0 appear in the current series) and an effective date.
  • Revisions are made by re-issuing the document with a new version number; earlier versions are superseded and are not to be used for purchasing decisions.
  • The review date shown on each page of this site records when that page was last checked against its source document — it is not the date of the underlying third-party standard.
  • Where a document and a page of this knowledge center conflict, the controlled document governs; please report the discrepancy so the page can be corrected.

4. What we will send you, and how

Document Availability
Product specification (controlled, current version) On request — for qualification and purchasing
Technical datasheet (flakes, powder) On request and published in this knowledge center
Certificate of analysis (COA) Issued per shipment; a specimen COA can be provided for evaluation
Quality & food safety manual, HACCP plan, certificates Available for customer audits and supplier qualification
Quality manual and process flow chart Available for download on the main website

Requests go through the contact route on the main website — see Request a Quote / Contact — or by email to [email protected]. State the product grade, the parameters you need verified and the method your own specification cites, so the correct controlled document is issued.

5. Corrections and change requests

We treat factual corrections as a document-control event, not a marketing edit:

  1. Send the document code (or page URL), the statement you believe is wrong, and the evidence or the primary source you are relying on.
  2. The responsible department is asked to confirm against the controlled document.
  3. If the page was wrong, it is corrected and the change is recorded; if the controlled document is being revised, customers holding the previous version are informed.
  4. Confirmed corrections are reflected in the page's review date.

See also Technical Data Governance for how values must be labelled when quoted (typical vs guaranteed, method, and version).

6. Why this matters to a buyer

  • A specification you can cite by code and version is auditable; an unversioned number on a web page is not.
  • A COA that states its method and lot number can be compared against the specification the order was placed against.
  • A documented change process means the figure you qualified your line against does not silently change.
