Direct Answer
An approved PE rattan sample should be linked to a controlled specification revision. A change to profile dimensions, cross-section, color formulation, surface, UV formulation, material formulation, frame geometry or other conditions that may affect the approved result should trigger documented review before the previous approval is reused.
Approved Sample Revision and Change-Control Record
Link every approved physical sample to the current specification revision, material item, profile, cross-section, measured dimensions, color reference, surface, UV formulation, material formulation, roll standard, intended application, approval date and buyer decision. An unlabeled strip cannot show which revision or order it controls.
A change to profile dimensions, cross-section, color formulation, surface, UV formulation, material formulation, frame geometry or another condition that may affect the approved result should trigger documented review before the previous approval is reused. This guide does not define universal automatic acceptance; the buyer's specification and risk determine the review.
Put the furniture program at the top
A good specification sheet starts with the product, not the material code. Write down whether the PE rattan will be used for outdoor sofas, dining chairs, cabinet inserts, baskets, decorative panels, or another furniture part.
Also note the market level and exposure. A hotel poolside collection, a covered patio chair, and a cost-focused local-market item should not be treated as the same order, even if the color looks similar in photos.
Describe the profile in measurable terms
Profile words such as flat, round, hollow, twisted, or brushed are useful, but they are still too general for production. Add width, thickness, diameter, wall structure, surface texture, and any drawing or cross-section photo you have.
If you are replacing an old material, send a short strip or a clear close-up with a ruler. The supplier can then check whether the profile should be copied exactly or adjusted for easier weaving on the current frame.
Separate color, surface, and UV grade
Color names are easy to write but easy to misunderstand. Natural, coffee, grey, black, and teak can mean different things to different factories. Attach an approved sample, color board, or old strip whenever possible.
Surface and UV grade should be written separately from color. A buyer may want a wood-look surface with a regular outdoor grade, or a simple flat strip with a stronger UV plan. Keeping these fields separate makes the quotation cleaner.
Add roll and packing requirements early
Roll length, roll weight, label information, carton use, pallet loading, and mixed loading can affect the workshop more than buyers expect. A roll that is difficult to handle can slow down production even when the material itself is correct.
If your warehouse has a preferred roll weight or label format, write it on the sheet. If several colors or profiles will ship together, ask the supplier how they will separate labels and packing so the factory floor does not need to guess.
Leave space for approval records
The final sheet should show which sample was approved, who approved it, and what version should be used for bulk production. This is especially important for repeat orders and long-running furniture collections.
A practical record includes item code, profile, color sample, UV grade, roll standard, packing method, batch number, and any special note from the weaving team. It does not need to be complicated, but it must be consistent.
What to send with the sheet
For a new inquiry, send the specification sheet together with furniture photos, frame details, old material samples if available, target quantity, destination, and expected production timing.
With these details, Greenlife Rattan can reply with a more practical material suggestion instead of only asking follow-up questions. It also helps both sides avoid approving a good-looking sample that does not fit the real production line.
When Should an Approved Sample Be Replaced?
Replace or formally supersede an approved sample when physical damage, fading or discoloration prevents reliable comparison; when its identity or revision link is missing; or when the controlled specification has been superseded.
A material, formulation, profile, dimension, surface, tooling, color or UV-grade change may require a new sample or defined recheck. A buyer-approved new revision should identify the new sample and state what happens to the superseded sample so it cannot be used as the current reference.
Change-Control Matrix
Use the current buyer approval and affected application to decide the recheck scope. The matrix does not define universal automatic acceptance or require a full resample for every change.
| Change | Current Approval Status | Recheck Required | New Sample May Be Required | Record to Update | Effective PO / Order |
|---|---|---|---|---|---|
| New production batch | Current approval remains linked only when the buyer's batch rule permits reuse | Batch identity, color, profile, surface and applicable incoming checks | When batch risk, deviation or the buyer's rule requires it | Batch record, inspection and approved-sample link | Confirm the effective PO / order and disposition before release |
| Resin/material formulation | Old approval does not automatically cover a changed material basis | Material identity, formulation reference, profile and matched sample | When processing or performance scope may change | Material revision, supplier record and approval | State the first PO / order covered by the reviewed revision |
| UV formulation | Old approval does not automatically cover a changed UV formulation | UV formulation reference, color, profile, exposure scope and evidence | When formulation or exposure position changes | UV revision, evidence record and buyer decision | Record the effective PO / order after buyer approval |
| Color formula | Changed color formulation is not covered by the old approval | Color reference, formulation scope and actual-profile comparison | When woven appearance or performance scope may change | Specification revision, color approval and sample record | Identify the first PO / order using the new color |
| Masterbatch | A changed masterbatch requires review of color and material scope | Masterbatch reference, color, formulation, profile and batch | When shade, dispersion or another approved result may change | Masterbatch record, comparison and sample decision | Record effective PO / order and supersede the old reference as directed |
| Profile dimensions | Old dimensional approval does not cover the new profile | Width, thickness/diameter, tolerance and actual-frame behavior | When fit, tension, coverage or appearance may change | Drawing, measurement record, sample and frame result | Link the new approval to the effective PO / order |
| Cross-section | Old cross-section approval does not cover the new geometry | Cross-section, dimensions, edges and actual-frame behavior | When fit, tension, coverage or appearance may change | Drawing, measurement record, sample and frame result | Do not apply the old approval to an order without review |
| Tooling | Tooling changes require review of the produced profile and surface | Tooling ID, dimensions, cross-section, surface and batch | When geometry, repeatability or appearance may change | Tooling revision, measurements and approved sample | Record the effective PO / order after the tooling review |
| Surface/texture | Review required for the changed surface or texture result | Texture, gloss, marks, cross-section and weaving behavior | When appearance, handling or cleaning may change | Surface revision, comparison and approved sample | State which PO / order uses the reviewed surface |
| g/m target | A changed grams-per-meter target is not covered by the old approval | Measured g/m method, profile, length basis and tolerance | When weight, coverage, roll planning or handling may change | g/m record, sample and buyer disposition | Identify the effective PO / order and accepted target |
| Frame geometry | Old approval may not cover a changed frame or bend route | Frame drawing, radii, edges, fixing and test weaving | When fit, tension or appearance may change | Frame revision, test panel and disposition | Apply only to the reviewed PO / order scope |
| Bend condition | Old approval may not cover a changed bend route or condition | Bend radius or route, temperature, direction, support and timing | When handling or finished-frame behavior may change | Controlled bend check and sample record | Record the first effective PO / order for the reviewed condition |
| Weaving pattern | Old approval may not cover a changed pattern or tension route | Pattern, spacing, direction, tension and actual-frame result | When panel behavior or appearance may change | Weaving instruction, sample and review | Link the approved pattern to the effective PO / order |
| Packing | Product approval may remain subject to buyer review when packing changes | Protection, identity, handling, labels and shipment risk | When packing could affect material condition or use | Packing revision and buyer disposition | Record the effective PO / order and packing instruction |
| Supplier/site | Old supplier/site evidence does not automatically transfer | Entity, site, process, specification, sample and traceability | Possible unless equivalence is demonstrated and accepted | Supplier/site record, evidence and new approval | State which PO / order is covered by the accepted site |
| Document-only correction | Approval may remain unchanged if the correction does not alter the controlled item | Corrected field, source record, revision and traceability | When identity, compliance or buyer records could be affected | Correction log and authorized review | Record the effective PO / order only if scope changed |

Buyer Decision Points
Approve the material only after the guide's relevant checks are tied to the actual product, frame, market, and repeat-order record.
- Approved Sample Revision and Change-Control Record
- Put the furniture program at the top
- Describe the profile in measurable terms
- Separate color, surface, and UV grade
Factory Process or Test Method
Start with the buyer's application and reference sample, document the relevant profile, color, performance, and packing requirements, then compare the production sample on the intended frame before bulk approval.
Common Mistakes
Common errors are approving from a screen photo alone, omitting the actual frame or exposure condition, treating a color name as a repeatable standard, and leaving packing or batch identification until after production.

Buyer FAQ
These answers explain how to apply the guide without treating it as a substitute for buyer-specific testing.
When should an approved PE rattan sample be replaced?
Replace or formally supersede it when it is damaged, faded, no longer traceable, or when a controlled change may affect the approved result and the buyer approves a replacement or new revision.
Does every new batch require re-approval?
Not automatically. The buyer should define the recheck scope from the current approval, batch risk, documented change and actual result; no universal automatic resampling rule is set here.
Does a color-formula change require a new sample?
It may. Review the color formulation, masterbatch, profile, surface, intended application and existing approval before deciding whether a new sample or defined recheck is required.
Can an old approval be reused after a profile change?
Do not reuse it automatically. A profile dimension or cross-section change can affect fit, tension, coverage or appearance, so document the review and buyer decision before applying the old approval.
What happens to superseded samples?
Mark the sample as superseded, retain its identity and disposition record, and prevent it from being mistaken for the current approval reference.
