Standard Box vs. Custom Size Box: Which One Fits Your Business Better?

Q1: What is Dimensional (DIM) Weight, and how do custom size boxes reduce it?

DIM weight is calculated as $(L \times W \times H) / 5000$ (or $139$ for US domestic). Decreasing box length, width, and height by just $2 \text{ cm}$ each reduces total cubic volume exponentially, dropping parcel shipping costs.

Q2: What is the initial minimum order quantity (MOQ) for custom size boxes at Gerun Packaging?

Our structural packaging MOQs start at 500 units for custom folding paperboard cartons and corrugated mailer boxes, making custom dimensions accessible for scaling DTC brands.

Q3: Can a custom size box be designed to hold multiple distinct SKUs simultaneously?

Yes. We engineer modular custom insert trays (foam, paperboard, or molded pulp) that fit inside a single standardized outer box, allowing one exterior custom box size to hold multiple product configurations securely.

Q4: How much tolerance buffer should be added when measuring a product for custom size boxes?

Typically, a clearance margin of $1.5 \text{ mm}$ to $3 \text{ mm}$ is added beyond the exact physical dimensions of your product to ensure smooth insertion and extraction without tight friction jamming.

Q5: Is a one-time die mold fee charged on repeat orders of custom size boxes?

No. Steel rule die molds and magnetic foil blocks engineered for your custom box dimensions are stored in our physical die library for up to two years. Tooling setup fees are waived on repeat re-orders.
