Prime MOQ for Manufacturers and Distributors

Enforce carton sizes and freight weight limits at checkout, so your storefront respects the packing and shipping constraints set upstream of it.

Short answer

Manufacturers and distributors usually have constraints set upstream of the store: a product ships only in cartons of a fixed size, or a pallet only makes sense past a certain weight. Use a case-pack rule for carton sizes and a weight rule for freight, and pick one governing constraint per product line.

  • Case-pack rules force orders into carton-sized multiples, so nobody orders a partial carton.
  • Weight rules cap or require total shipment weight for pallet and LTL logic.
  • How to count decides whether each SKU needs its own full carton or the order does.
  • One product is governed by one rule, so when packing and freight collide, enforce the harder constraint.

Why manufacturers and distributors use Prime MOQ

If you manufacture or distribute physical goods, your constraints are often set upstream of your Shopify store entirely. A product only ships in cartons of a fixed size, or a pallet only makes financial sense past a certain total weight. Prime MOQ lets the storefront enforce those real-world packing and freight constraints instead of relying on customers to read a note in the product description.

A typical case-pack rule

For a product line sold only in cartons of 12:

  • Limit type: Quantity
  • Sell in multiples of: 12
  • Applied products: the collection or product type covering that line
  • How to count: Each item separately, so every product in the collection must independently be ordered in a multiple of 12. Use Combined total instead if any mix of SKUs from the collection can add up to 12.

A weight-based freight rule would instead cap Maximum total weight across a heavy-goods collection, so a single order never exceeds what a standard shipment can carry.

Multiple constraints, one rule each

A product belongs to one rule at a time, so if a product line has both a case-pack requirement and a weight cap, decide which one actually governs. That is usually weight, since it is the harder physical constraint. Enforce the other through your variant setup, for example by only selling that item as fixed-size carton variants. See Why Only One Rule Applies Per Product.

Frequently asked questions

How do I stop customers ordering partial cartons?

Use a Quantity rule with Sell in multiples of set to your carton size. Any quantity not evenly divisible by that number is blocked at checkout, so 5 and 10 fail against a carton of 6 while 6 and 12 pass.

Can customers mix SKUs to fill one carton?

Only if How to count is set to Combined total, which sums every matching product before checking divisibility. Use Each item separately when each SKU has to be ordered in its own full carton.

How do I set a freight minimum instead of a cap?

Use the Weight limit type with a Minimum total weight, so orders below the weight that makes a shipment worth dispatching are blocked. You can set a minimum and a maximum in the same rule to express "worth dispatching, but within one pallet".

My weight rule never triggers. What is wrong?

Almost always missing product weights. The check reads the weight field on each Shopify product or variant, and a product with no weight counts as zero, which lets a heavy cart pass a maximum-weight rule. Audit weights before relying on the rule.

Different product lines have different carton sizes. How do I handle that?

One rule per line, each scoped to the collection or product type that ships in that size. Since a product is governed by one rule at a time, keep those scopes from overlapping.

Can I apply freight rules only to certain shipping regions?

Yes. Set Countries under Customer eligibility to Selected countries, which is common when a freight minimum only applies to domestic LTL lanes.

Best for: Manufacturers, importers and distributors whose products have fixed packaging units or freight-driven order limits.

Applies to: Quantity and Weight limit types
