A bulk apparel order may contain the correct total quantity but still be packed incorrectly. If cartons contain the wrong combination of sizes or colors, a buyer’s warehouse may need to reopen cartons, recount garments, or reorganize inventory after delivery.
Mixed-size carton packing should be treated as a defined order requirement rather than a last-minute decision made at the packing station.
1. Choose the Right Packing Method
Before production is completed, clarify whether the order should use solid packing, assorted packing, or fixed ratio packing.
- Solid packing: A carton contains one specified style, color, and size combination, according to the buyer’s instructions.
- Assorted packing: A carton contains a mixture of products, but the exact mix must still be documented.
- Ratio packing: Each carton follows a defined size or color ratio, such as a repeating assortment across several sizes.
The right option depends on how the buyer plans to distribute, store, or sell the garments. Do not assume that a previous order’s packing method applies to a new order.
2. Define the Exact Size and Color Ratio
A packing instruction should state the quantity of each size and color in every carton or pack. If multiple garment styles are involved, identify them separately.
For example, a carton might contain a specified mix of small, medium, large, and extra-large shirts. The exact ratio should be agreed with the buyer rather than selected by the factory.
Also define how to handle remaining units when the order quantity does not divide evenly into complete ratio packs. Options may include a separately identified balance carton or another arrangement approved in writing.
3. Reconcile Carton Quantities with the Order
Check the packing plan at several levels:
- Quantity of each SKU
- Quantity by size and color
- Quantity per inner pack or carton
- Total cartons
- Total shipment quantity
These figures should reconcile with the purchase order and final packing list. A correct grand total alone is not enough: extra small garments and missing medium garments can cancel each other out numerically while leaving the buyer with the wrong assortment.
4. Agree on Carton Identification
Every carton should be identifiable according to the buyer’s receiving requirements. Confirm which information must appear on the carton, such as purchase order number, style, color, size range, carton sequence, and quantity.
If cartons contain mixed products, the external marks should make that clear. Avoid labels that imply a carton contains one size when it actually contains several.
The carton markings and packing list should be generated from consistent, approved information. Any changes to the packing arrangement should be reflected in the final records.
5. Inspect the First Completed Cartons
Before closing all cartons, ask the factory to check the first completed cartons against the approved packing plan. Where appropriate, buyers can request photographs or a documented carton check.
During final inspection, select cartons from different parts of the shipment and verify their contents against the carton marks. The inspection method and sample size should be agreed in advance, especially for large or multi-destination orders.
Our Approach to Custom Apparel
A practical carton plan identifies each style-color-size combination, the required packing ratio, the number of units per carton, and the labeling method. It should be shared with the packing team and the buyer’s receiving contact before packing begins.
For orders shipping to several warehouses or distributors, prepare separate instructions for each destination. This reduces the risk of sending the correct products to the wrong location or delivering an assortment that does not match local demand.

Conclusion
Mixed-size packing is an important part of fulfilling a custom apparel order accurately. Confirming the packing method, exact ratios, carton labels, and final quantity reconciliation helps buyers reduce receiving problems and maintain better control over bulk shipments.
