Changing fishing net suppliers can create hidden specification risk.
A buyer may send the new factory:
An old sample
A previous invoice
A few photos
A short product description
and ask:
“Please make the same product.”
But this is often not enough.
The key principle is:
Supplier switching should transfer the approved technical specification, not only the old physical sample.
A used or stored net may have changed over time.
It may show:
Deformation
Surface wear
Flattened twine
Changed mesh geometry
Faded color
These characteristics may not represent the original factory condition.
A sample is useful, but it should be supported by written data.
Before contacting a new supplier, gather:
Material
Mesh size
Measurement method
Twine specification
Dimensions
Knot type
Color
Border construction
Packaging
This gives the new factory a clearer starting point.
Old records may contain several versions.
For example:
Original quotation
Later purchase order
Revised drawing
Warehouse record
Do not assume the earliest document is the final approved version.
Use the latest verified production specification.
If the old supplier wrote only:
50 mm mesh
the new supplier may interpret it differently.
Confirm whether it means:
Knot-to-knot
Stretched mesh
Clear opening
This is one of the most important steps in supplier transfer.
Different suppliers may describe twine using different systems.
The buyer may have:
Diameter
Denier
Ply
Strand count
If possible, provide both the documented specification and a reference sample.
Do not assume two supplier terms are automatically equivalent.
The new supplier should know whether dimensions refer to:
Relaxed condition
Stretched condition
Finished panel dimensions
For custom panels, also provide:
Mesh count
Border length
Attachment positions
This reduces interpretation differences.
The old product may contain important construction that is not obvious from the main net.
For example:
Border rope diameter
Corner reinforcement
Lacing
Loops
Seam position
These details should be documented separately.
Supplier switching is not only about the net itself.
Also provide:
Packing type
Rolls per package
Labels
SKU
Barcode
Shipping marks
This is especially important for distributors and OEM buyers.
Some characteristics may need to remain unchanged.
Others may allow alternatives.
For example:
Mesh size
Dimensions
Twine construction
Neutral packaging
Minor color variation
Supplier internal code
Defining this early gives the new supplier clearer boundaries.
Do not simply send information and assume it is understood.
Ask the new supplier to return a structured specification showing:
What they understood
What they can match
What may differ
This creates an early technical cross-check.
Build a comparison table.
Check:
Material
Mesh
Twine
Dimensions
Construction
Color
Packaging
Any difference should be reviewed before sample production.
Even with good documentation, a new factory may use different:
Machinery
Yarn preparation
Finishing
Packing methods
A new sample helps confirm whether the transferred specification produces the expected result.
Two nets may look similar but differ technically.
Sample approval should check:
Mesh size
Twine
Dimensions
Construction
Border details
Visual similarity is only one part of equivalence.
For important SKUs, avoid moving the entire annual volume immediately.
A trial order can test:
Bulk consistency
Packing
Lead time
Documentation
Communication
This reduces switching risk.
During the transition period, identify which stock came from which supplier.
Record:
Supplier
Batch
Shipment
SKU
This makes customer feedback easier to trace.
Once the new supplier is approved, update internal records.
Include:
New supplier code
Approved sample reference
Latest specification revision
Packaging reference
Do not leave the new supplier linked only through informal email history.
Collect from the old product:
Material
Mesh size
Measurement method
Twine specification
Knot type
Dimensions
Mesh count
Borders
Reinforcement
Packaging
Confirm with the new supplier:
Rebuilt specification
Differences identified
Sample produced
Sample inspected
Trial order completed
Supplier code recorded
Batch traceability maintained
Buyer sends:
“Please copy this old green net.”
The new supplier must guess:
Material
Mesh method
Twine specification
Original dimensions
Packaging
The final product may look similar but still be different.
Buyer provides:
Material: PE
Mesh: 50 mm knot-to-knot
Twine: 2.0 mm
Construction: Knotted
Size: 5 m × 100 m
Color: Green
Packing: One roll per bag
Reference: Approved old sample + final specification Rev. 04
Now the new supplier has both physical and written references.
Supplier changes may happen because of:
Price
Capacity
Lead time
Quality concerns
Supply risk
But switching factories should not accidentally change the product sold to customers.
A controlled transfer helps protect:
SKU consistency
Customer expectations
Repeat-order accuracy
Warehouse records
A new supplier cannot reliably reproduce a product from appearance alone.
The key question is:
What technical information defines the product that must remain consistent after the supplier changes?
The key principle is:
Supplier Transfer = Approved Specification + Physical Reference + Difference Review + Sample Approval + Trial Production
At PL Fishery, we manufacture PE fishing nets, nylon fishing nets, aquaculture netting, fish cage panels, reinforced netting, commercial net rolls, marine ropes, repair twine, and customized net products for importers and distributors.
If you are transferring an existing fishing net specification to a new supplier, send PL Fishery your old specification, sample photos, material, mesh size and measurement method, twine specification, dimensions, packaging, annual volume, and critical requirements so our factory can prepare a comparable production proposal.https://plfishery.com/
