Shipping rates not showing
Updated · SMART Shipping Rates (E-TRADE PARTNER)
If a SMART calculated shipping rate is not showing, check Shopify Carrier Service first, then confirm the checkout cart, address, zone, origin, product, weight, volume, quantity, and price conditions all match. Use Checkout simulator to replay the cart, then Activity log after a live checkout. Delivery customizations do not create new rates, so they will not make a missing calculated rate appear.

A missing rate usually means Shopify did not receive an eligible calculated rate for that checkout. Work through the checks in order so you do not spend time changing product rules when the store is missing Carrier Service.
Fast checklist
- Confirm the rule is a Shipping rates or Combined rates rule, not only a delivery customization.
- Confirm Shopify Carrier Service is available. Zone creation is disabled without it.
- Check whether the store is on a Shopify plan that can use Carrier Service. The app banner states that Basic plan stores cannot enable Carrier Service.
- Run Checkout simulator with a cart and destination that should match the rule.
- If the simulator or a live checkout still looks wrong, open Activity log and check the No rates returned tab.
- Test with an address inside the configured country, city, postal code, wildcard, or range.
- Check cart total, cart weight, cart quantity, cart volume, dimensional weight, product, origin, date, and time conditions.
- Check whether product tags, shipping tags, or combined-rate tags are spelled consistently.
- Review Settings for units, volumetric divisor, default dimensions, multiple rates behavior, and rounding.
- Replay the cart in Checkout simulator, then check Activity log after a live checkout (entries are kept up to 48 hours).
Carrier Service symptoms
| Symptom | Likely cause | What to check |
|---|---|---|
| Zone creation is disabled | Carrier Service is not available | Open Shipping rates and review the Carrier Service banner |
| No calculated SMART rate appears | Shopify cannot receive the app rate or the rule does not match | Check Carrier Service, then run Checkout simulator and review Activity log |
| Delivery customization works but new rate does not | Different module requirements | Delivery customizations do not need Carrier Service, calculated rates do |
| Combined rate does not appear | Tagged calculated rates are missing or not matching | Check shipping tags and included rates |
Condition mismatch checks
- Use Checkout simulator with an address that exactly matches the intended country and city.
- For postal code rules, test one value inside the range and one outside it.
- Check wildcard * and range ... patterns carefully.
- Make sure cart and product weights use the expected unit from Settings.
- For volume or dimensional-weight rates, confirm Product dimensions and the volumetric divisor.
- Confirm the cart includes the products or quantities the rule expects.
- For origin conditions, confirm Ship from location in the simulator matches the warehouse you meant.
When the issue is not a missing rate
If Shopify already shows the correct rate but the method name, order, or visibility is wrong, use Delivery customizations. If several SMART rates show separately and should become one, use Combined rates.
Checkout simulator does not run delivery customizations
Checkout simulator tests calculated rates only. It does not evaluate Delivery customizations (hide, rename, or reorder). Simulator results can also differ from checkout for items that do not require shipping. Use a real Shopify checkout to verify those cases.
For setup context, read Carrier Calculated Shipping, Checkout simulator, Activity log, and the shipping zones guide.

Frequently asked questions
›Why is my SMART rate not appearing?
The most common causes are missing Carrier Service for calculated rates or a checkout cart and address that do not match the rule conditions.
›Why is zone creation disabled?
Zone creation is disabled when Shopify Carrier Service is not available.
›Can delivery customizations create a missing rate?
No. Delivery customizations control existing checkout methods. Use Shipping rates when SMART must create a calculated rate.
›How should I test a missing rate?
Run Checkout simulator with a cart and destination that should match. If a live checkout still looks wrong, open Activity log and check the No rates returned tab. Also test a non-matching cart to confirm the rule boundary.
