Who Should Assign the GTIN for a Private Label Herbal Patch Order?
August 9, 2026GTIN, SKU y Lote en Parches de Marca Privada: Diferencias para el Distribuidor
August 9, 2026Short answer: sometimes. Under the cited GS1 rule, a change of more than 20% to any physical dimension or to gross weight requires a new GTIN. A smaller change can still require a new identifier under another GTIN rule, a local regulation or a trading-partner requirement. Review the complete trade item and packaging hierarchy before reprinting.
Buyer question: how is the percentage calculated?
Answer: compare each proposed physical dimension with the corresponding approved dimension. Use the original value as the denominator.
Percentage change = (new dimension - old dimension) / old dimension × 100
Hypothetical example
| Measure | Approved box | Proposed box | Change | Initial GTIN action |
|---|---|---|---|---|
| Length | 100 mm | 125 mm | 25% | New GTIN required under the cited dimensional rule |
| Width | 80 mm | 80 mm | 0% | No dimensional trigger on this axis |
| Height | 20 mm | 22 mm | 10% | Check other rules and partner requirements |
These dimensions are hypothetical and are not AnTie product specifications. The example shows the decision method only.
Evidence and limitations
Evidence: GS1’s GTIN Management rule states that a change over 20% to a physical dimension on any axis, or to gross weight, requires a new GTIN. It also notes that local, national or regional regulations take precedence.
Limitation: the 20% threshold is not permission to ignore smaller changes. A new declared net content, pack count, primary brand, formulation/functionality or other material trade-item change can be governed by a different rule.
What should the buyer review before approval?
- Record the approved box dimensions and gross weight.
- Measure the proposed packed box using a consistent method.
- Calculate every axis and gross-weight change separately.
- Review retail box, inner pack and master carton as distinct hierarchy levels.
- Check whether pack count, declared content, brand or channel presentation also changes.
- Confirm the applicable GS1 Member Organisation, market and retailer rules.
- Release the new artwork only after the GTIN decision is documented.
Why this matters for a 12-patch retail box
AnTie Family’s Wormwood Shoulder Patch reference contains 12 patches per retail box. A private-label buyer may change the box to fit a new insert, language panel or shelf format. Pack count is one decision; box dimensions are another. Both should be controlled before the buyer approves artwork, carton marks and warehouse records.
Review OEM/ODM packaging, compare the Wormwood Shoulder Patch reference, read the five packaging layers buyers should quote separately, and confirm project data through contact.
Frequently asked questions
Does moving the barcode require a new GTIN?
Barcode placement alone is not the same as changing the trade-item identity, but print quality, scanning and partner requirements still need approval.
Does changing the number of patches require review?
Yes. Declared net content or pack quantity is covered by separate GTIN management rules.
What if the retail box changes by 18%?
The cited dimensional threshold is not triggered by that figure alone, but another rule, regulation or partner requirement may still require a new GTIN.
Does a master-carton change matter?
Yes. Higher packaging levels that are trade items require their own hierarchy review.
Decision rule: calculate, classify and document before printing. Do not let the artwork supplier decide GTIN continuity by default.
