Shipping & Volume FAQ
How do I choose between 20ft, 40GP, and 40HQ containers?
It depends on your total volume (CBM) and weight. A 20ft container holds approx. 33 CBM and is best for heavy goods. A 40ft GP holds approx. 67 CBM, suitable for large general cargo. A 40ft HQ (High Cube) holds approx. 76 CBM and is ideal for voluminous but lighter goods. Use our calculator above to see which fits your order best.
Can REPA consolidate shipments from different suppliers?
Yes. We can collect goods from multiple suppliers and consolidate them into a single shipment at our warehouse. This significantly reduces your shipping costs and simplifies customs clearance processes. We provide flexible transportation solutions tailored to your specific requirements.
What if my cargo is lost or damaged during shipping?
We aim to minimize risks for our partners. If you use our shipping service, REPA will assist you in claiming compensation from the shipping agent or insurance company. We are committed to ensuring your sourcing process is both efficient and safe.
What is CBM and why is volume key for sea freight?
CBM stands for Cubic Meter. It is the standard unit used to measure the volume of your shipment.
Why it matters: In ocean freight--especially for LCL (Less than Container Load)--shipping lines charge based on the space your cargo occupies rather than its weight. Knowing your CBM allows you to estimate shipping costs accurately and determine if your shipment is cost-effective.
My CBM is low, so why am I charged for "Volumetric Weight"?
This occurs due to Chargeable Weight. Carriers compare the actual physical weight of goods against their "volumetric" (dimensional) weight and charge for whichever is higher.
The Logic: If you ship light but bulky items (like plush toys), they consume significant container space. Carriers use a "dim factor" (e.g., L x W x H / 6000) to convert that volume into a billable weight equivalent.
How many shipping containers do I need based on CBM?
Compare your total CBM to these standard capacities:
- 20ft General Purpose (20GP): ~28-30 CBM
- 40ft General Purpose (40GP): ~58-60 CBM
- 40ft High Cube (40HQ): ~68-70 CBM
Pro Tip: Never plan for a 100% fill rate. Due to "dead space" and potential carton bulging (expansion), always assume a 10% margin of error in actual loading capacity to avoid unexpected overages.
How does palletization affect my final CBM calculation?
Palletizing goods significantly increases total CBM. You must calculate volume based on the pallet's footprint (e.g., 1.2m x 1m) and the total height including the pallet itself (which usually adds 10-15cm).
Advice: If your shipment requires pallets, always calculate the volume of the entire "pallet stack" rather than individual boxes to ensure your freight budget is accurate.
