When you sell product variants with the same physical dimensions and weight (like different colors, flavors, or sizes that fold identically), you can lock in consistent measurements across all variants. This ensures accurate fulfillment pricing and prevents measurement discrepancies between identical items.
## What Are Identical Products? Identical products are variants of the same item that share identical physical characteristics: **Same dimensions and weight across all variants** means products like: * T-shirts in different colors (Small Red, Small Blue, Small Green) that all fold to the same size * Candles in different scents with identical jar sizes and weights * Supplement bottles with different flavors but identical bottle dimensions * Shoes in different colors (if the same size) with identical packaging Even when products vary in attributes like color, flavor, or style, if their physical measurements match exactly, they qualify as identical products. *** ## Why Lock Dimensions for Identical Products? Locking dimensions and weights for identical products provides several benefits: | Benefit | How It Helps | | -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Consistent Fulfillment Costs** | | | **Accurate Pricing** | | | **Efficient Processing** | | Even with locked dimensions and weights, Jetpack still weighs each package individually for accurate shipping cost calculations. The locked measurements ensure consistency, but actual shipping costs are based on the specific package being sent. *** ## How to Lock Dimensions for Identical Products To lock dimensions and weights for your identical product variants, follow this process: ### Step 1: Gather Inventory IDs Collect the inventory IDs (also called SKU IDs) for all product variants that share identical measurements. You can find inventory IDs in your [Product Catalog](/fulfillment/managing-products) by viewing the product details for each variant. ### Step 2: Submit Request via Jetpack Care Contact Jetpack Care via Slack or email with: * **List of Inventory IDs** for all identical variants * **Confirmation** that all variants have identical dimensions and weight * **Request** to Cubiscan one unit and apply measurements to all variants ### Step 3: Jetpack Cubiscans One Unit Jetpack's receiving team will use Cubiscan technology to precisely measure one unit from your identical product group. Cubiscan captures: * **Length, width, and height** in inches or centimeters * **Weight** in pounds or kilograms * **Dimensional weight** for shipping calculations ### Step 4: Measurements Applied to All Variants Once Cubiscan measurements are captured for one unit, Jetpack applies those exact measurements to all variants in your identical product group. This locks in consistent dimensions and weight across the entire variant family. Before submitting a request, physically verify that all variants truly have identical dimensions when packaged. If variants differ even slightly in size or weight, they should not be grouped as identical products. *** ## Requirements for Identical Products To qualify for identical product measurement locking, your variants must meet these criteria: | Requirement | Details | | ---------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Identical Packaged Dimensions** | | | **Identical Weight** | | | **Consistent Packaging Materials** | | *** ## Managing Identical Product Groups Once your identical products have locked measurements, keep these management practices in mind: ### Adding New Variants When you add new variants to an existing identical product group: 1. Verify the new variant has identical measurements to the existing group 2. Contact Jetpack Care to add the new variant's inventory ID to the locked measurement group 3. Jetpack will apply the existing Cubiscan measurements to the new variant ### Changing Product Packaging If you change packaging for any variant in an identical product group: 1. **Notify Jetpack Care immediately** if packaging changes affect dimensions or weight 2. Request new Cubiscan measurements to update the locked dimensions 3. All variants in the group will be updated with new measurements Remember: Even with locked dimensions, each package is still weighed individually during fulfillment. This ensures accurate carrier billing based on the actual shipped weight. *** ## Let's Dive Deeper Back to the main guide on our receiving process Send your identical product variants to fulfillment centers Create variant product families with different colors and sizes Configure product specifications and settings Barcode requirements and best practices for variants View and manage all your products and variants *** If you have any questions or run into issues, you can always contact Jetpack Care for help.
