Custom fishing net orders often go through several rounds of discussion.
The buyer may change:
Mesh size
Twine diameter
Net dimensions
Color
Border construction
Packaging
These changes are normal during quotation and sample development.
But before bulk production begins, the order needs a clear point where the final specification is frozen.
The key principle is:
Bulk fishing net production should start only after the buyer and supplier confirm one final approved specification version.
A specification freeze means the buyer and supplier agree that the technical requirements are final.
After this point, production should follow the approved version.
Typical frozen information includes:
Material
Mesh size
Mesh measurement method
Twine specification
Knot type
Dimensions
Color
Borders
Reinforcement
Packaging
Quantity
This creates one official production reference.
During negotiation, information may exist in:
Emails
WhatsApp messages
Quotations
Samples
Drawings
Purchase orders
If these documents contain different values, the factory may not know which version is final.
For example:
An early message says:
Mesh: 50 mm
A later sample uses:
60 mm
But the purchase order still shows:
50 mm
Without a specification freeze, this can become a production dispute.
Before production, consolidate the important requirements into one document.
The specification sheet can include:
Product code
Material
Mesh
Twine
Dimensions
Construction
Color
Quantity
Packing
This reduces the need to search through old messages.
Each major change should create a new revision.
For example:
Rev. 0 — Initial quotation
Rev. 1 — Mesh changed
Rev. 2 — Border updated
Rev. 3 — Final approved version
Production should use only the approved revision.
A freeze date makes the production status clearer.
For example:
Specification Freeze Date: August 28, 2026
Any change requested after this date should be treated as a formal revision.
This is especially useful for long or complex projects.
A sample may be approved before bulk production.
But the sample should not exist separately from the written specification.
Record:
Sample reference
Sample date
Approved specification revision
This helps connect physical approval with written requirements.
For fish cage panels or custom project netting, the final drawing should also be frozen.
The drawing should show:
Dimensions
Mesh direction
Borders
Seams
Loops
Reinforcement
The final drawing revision should match the specification sheet.
A specification freeze should also confirm the commercial production quantity.
This is important because changing quantity may affect:
Material purchasing
Production scheduling
Packaging
Price
A frozen technical specification with an unclear quantity is still incomplete.
Packaging is often treated as a final-stage issue.
But custom packaging may require:
Printed bags
Labels
Cartons
Barcodes
Shipping marks
If these change late, shipment may be delayed even when the net itself is finished.
If the buyer changes:
Twine diameter
Mesh size
Material
Net dimensions
Reinforcement
the original quotation may no longer apply.
A final price should therefore match the frozen specification.
This prevents comparing the final product with an outdated quotation.
Late technical changes may affect:
Material preparation
Machine setup
Finishing
QC
Packaging
The delivery schedule should be reconfirmed after the final specification is frozen.
Sometimes a buyer still needs to change the order after production planning has started.
In that case, the change should be documented.
Record:
What changed
Old value
New value
Price impact
Lead-time impact
Production status
This turns an informal request into a controlled revision.
A change requested before material preparation may be relatively easy.
The same change requested after:
Netting production
Cutting
Seaming
Packing
may create much more cost and waste.
Always check production status before approving a late revision.
Factories should not have to determine the final specification by reading the last WhatsApp message.
Informal chat is useful for discussion.
Final production requirements should be consolidated into controlled documents.
This becomes increasingly important as order complexity grows.
The final purchase order should match the frozen technical documents.
Check:
Product code
Description
Quantity
Price
Packaging
Revision reference
If the PO and specification conflict, resolve the difference before production.
Before bulk production, confirm:
Material
Mesh size
Mesh measurement method
Twine specification
Knot type
Dimensions
Mesh count where required
Color
Borders
Reinforcement
Attachment details
Quantity
Packaging
Labels
Final drawing
Approved sample reference
Revision number
Freeze date
Commercial confirmation:
Final price
MOQ
Lead time
Payment terms
Trade term
Initial quotation:
50 mm mesh / 1.5 mm twine
Later message:
Please make twine thicker.
Sample:
2.0 mm twine
Purchase order:
1.5 mm twine
This order now contains conflicting instructions.
Final specification:
Revision 03
PE
50 mm knot-to-knot
2.0 mm twine
5 m × 100 m
Green
Knotted
Standard bale packing
Status:
Approved for Bulk Production
Now the factory has one clear production reference.
For importers, distributors, and project buyers, late specification changes can create:
Wrong production
Price disputes
Delivery delays
Mixed packaging
Rework
Unusable inventory
A formal freeze reduces these risks.
The frozen version can also become the reference for future purchases.
Instead of saying:
“Same as last time.”
the buyer can say:
“Repeat Specification Rev. 03.”
This makes repeat ordering much clearer.
Changes are normal during product development.
But bulk manufacturing needs one final reference.
The key question is:
Which exact version is the factory authorized to produce?
The key principle is:
Specification Freeze = Final Technical Version + Final Commercial Terms + Controlled Change Process
