Control Repeat-order Specifications

Transmission supply experience since 2008 supports clear model and drawing references for repeat orders. Make repeat purchasing traceable to the approved item details rather than a previous order description alone.

Repeat orders retain a clear specification baseline

A previous supply reference supports review, while the current order confirms what remains the same and what changes.

Previous baseline

Previous item or order reference
Confirmed brand and model
Drawing revision, if applicable

The earlier specification provides an identifiable starting point.

Current demand

Current quantity
Required delivery date
Packaging or destination changes

The new order establishes its own commercial and delivery requirements.

Change review

Model or drawing differences
Material or inspection changes
Approved alternatives, if any

Differences are reviewed against the previous specification.

Order confirmation

Current agreed specification
Confirmed changes
Order and delivery references

The current confirmation becomes the reference for this repeat order.

Reference the accepted baseline

Include the previous order or quotation reference together with the current part numbers and quantities. Keep the approved model and drawing revision visible in the new request.

Identify changes explicitly

Highlight changed material, dimensions, finish, model suffix or packing requirements. State which items are unchanged and which require a fresh technical or commercial review.

Reconfirm current supply conditions

Request updated availability, timing and commercial terms for the new quantity. A previous purchase is not a promise of current stock, pricing or identical lead time.

Keep approval records connected

Record approved alternatives and revision changes against individual lines. Maintain the latest accepted specification so subsequent orders do not accidentally revert to an older version.

Existing documents remain useful.

BOMs, model lists and drawings can form the starting point; open specifications stay marked for review. Submitted inquiries and attachments are saved to ZOFANG’s server for review.
