f shipping rates displayed at checkout appear too high, too low, or inconsistent with expectations, the cause is usually related to product data, address input, or carrier rules. This article explains the most common reasons for incorrect pricing and how to resolve them.
Common Causes of Incorrect Pricing #
1. Incorrect product weight or dimensions
- Pricing is based on the greater of dead weight or cubic weight
- Overestimated dimensions can significantly increase the calculated freight cost
- Missing or default values may cause fallback behaviour
2. Packaging type not configured properly
- A product may be assigned a packaging type that doesn’t reflect how it’s actually shipped
- Default packaging may not match the item’s size, leading to incorrect cubic weight calculation
3. Residential vs. commercial delivery settings
- Carriers may apply residential surcharges automatically
- If the delivery type is set incorrectly in app settings, additional charges may be applied
4. Incomplete or regional addresses
- Remote or regional areas may attract higher delivery fees
- A minor address detail (such as a misspelled suburb) may route the shipment differently
5. API caching
- The plugin uses caching to reduce API calls
- Previously calculated rates may be temporarily reused if no change is detected
What to Check #
- Review the weight and dimensions for all affected products
- Check the packaging type configured in the Loadlink app settings
- Confirm that pickup and delivery building types are set correctly
- Test the same product with a known metro address for comparison
- Clear cache or re-save product data to refresh rate calculations
How to Correct the Issue #
- Adjust the product’s dimensions and weight to reflect actual packed size
- Use realistic data – avoid padding measurements unnecessarily
- Confirm that only physical, deliverable items are included in the cart
- Recalculate rates using the test tool in the Loadlink app
Contacting Support #
If rates still appear inaccurate after checks, contact Loadlink support with:
- Product name or URL
- Destination address
- Expected vs. returned shipping price
- Any packaging or handling instructions that apply
