Wholesale and distributor orders should ship as parcels when each carton stays inside a carrier's published weight and size limits and the order is a handful of cartons; they should ship as LTL freight when the order is palletized, exceeds parcel limits, or would need so many cartons that per-carton handling costs more than a pallet. The line is not a single weight; it is a combination of carton count, carton size and destination. This guide lays out the carrier-published limits that force the decision, the rules distributors use to split orders between the two modes, and how a pay-as-you-go parcel account with side-by-side USPS, UPS, FedEx and DHL rates handles the parcel side without a monthly fee.

What are the parcel limits that force the LTL decision?

Parcel carriers publish hard limits, and any carton outside them cannot ship as a parcel regardless of price.

USPS accepts domestic packages up to 70 lb. Length plus girth is capped at 108 inches for most services and 130 inches for USPS Ground Advantage, per USPS.
UPS accepts packages up to 150 lb, up to 108 inches in length, and up to 165 inches in length plus girth, per UPS. Packages above certain size or weight thresholds carry a published large package or additional handling surcharge.
FedEx ground services accept packages up to 150 lb and up to 108 inches in length, with 165 inches length plus girth, per FedEx, with similar oversize surcharges.
DHL limits vary by service and are stated in DHL's published terms.

Below those caps, a carton is parcel-eligible. Above them, or when a carton is heavy enough to trigger additional handling fees on every unit, freight becomes the practical option. Our package size and weight limits page lists the published figures by carrier.

When does parcel still win for a wholesale order?

Distributors often assume any B2B order is freight. In practice parcel wins more often than expected:

Few cartons, moderate weight. An order of four cartons at 30 lb each is well inside parcel limits. Four parcel labels avoid the freight pickup scheduling, the pallet, and the receiving dock requirement at the customer.

Customers without a dock. Retail boutiques, salons and small restaurants receive parcels at the front door. An LTL delivery to an address without a dock triggers liftgate and residential or limited-access fees on the freight side.

Split-ship and replenishment. Weekly top-up orders that are small and frequent are almost always cheaper as parcels than as a weekly pallet.

Speed. Ground parcel transit is predictable and tracked carton by carton; LTL transit depends on terminal schedules.

When does LTL win?

Freight wins when the order is heavy, uniform and going to a dock:

Palletized orders. Once the customer orders a full pallet or more, freight is the correct mode. Breaking a pallet into 40 parcels is slower to pack and each parcel is handled separately.
Cartons over parcel caps. A single 180 lb crate has no parcel option.
Fragile bulk. Glass, ceramics and liquids in quantity travel better shrink-wrapped on a pallet than as individual cartons subject to conveyor handling.
Density. Freight is classed by density and commodity. Dense, stackable goods get favorable freight classes; light, bulky goods do not, and may still be cheaper as parcels.

How should a distributor set the split rule?

The practical rule set most distributors converge on:

Rule 1: Carton eligibility first. If any carton exceeds a parcel carrier's published weight or size cap, that carton is freight. Do not try to force it.
Rule 2: Count the cartons. Set a carton threshold based on your own packing time and the customer's receiving setup. Many distributors use a range between six and twelve cartons as the point where they quote freight.
Rule 3: Check the destination. No dock, no forklift, no receiving hours means parcel unless Rule 1 forces freight.
Rule 4: Rate the parcel side properly. For the parcel portion, quote every carton across USPS, UPS, FedEx and DHL rather than defaulting to the account you have always used. Heavy cartons between 70 lb and 150 lb are automatically a UPS or FedEx comparison because USPS is capped at 70 lb.

Rule 4 is where wholesale shippers leave money on the table, because B2B teams often have one legacy carrier account and never see the alternatives.

A worked example: a beverage distributor

A specialty beverage distributor receives an order for 8 cases from a cafe with no loading dock. Each case is 12 x 12 x 10 inches and weighs 34 lb.

Rule 1. Every case is under the 70 lb USPS cap and well under the 150 lb UPS and FedEx caps. All are parcel-eligible.

Rule 2. Eight cartons sits at the lower end of the distributor's freight threshold.

Rule 3. No dock. An LTL delivery would require a liftgate and would be billed as limited access. That tips the order to parcel.

Rule 4. In the "To Ship" queue, all eight cases are quoted across the four carriers. At 34 lb per case the USPS quote is compared against UPS and FedEx ground; the winner depends on zone and residential status. USPS Ground Advantage includes $100 of insurance per package against loss or damage, per USPS, which is relevant when each case is worth more than that and additional coverage should be considered. The team picks the lowest quote meeting the delivery date, buys eight labels from the prepaid wallet and prints them through PrintNode.

Had the same cafe ordered 40 cases, Rules 2 and 3 would conflict, and the distributor would quote freight with a liftgate and compare against 40 parcel labels before deciding.

How does the parcel side fit into wholesale systems?

Wholesale orders rarely come from a Shopify checkout. They come from an ERP, an order sheet, or a B2B marketplace. Three paths bring them into a parcel workflow:

Bulk CSV import with header aliasing takes an ERP export of carton-level rows and maps columns once.
The public REST label API with one Bearer header lets an ERP create labels at pick-out without human handling.
Store connectors cover the retail side; GoatLabels has 13, including Shopify, WooCommerce, Amazon and Walmart, and all orders land in one "To Ship" queue next to imported wholesale rows.

There is no monthly fee, so a distributor that ships freight most of the time and parcels occasionally is not paying for idle software. The wallet is funded by card or other methods and each label draws its quoted amount; see pricing. Questions on origins (US and Singapore), voids and printer setup are in the FAQ. You can sign up and rate your next multi-carton order in minutes.

Quick answers

When should a wholesale order ship LTL? When cartons exceed parcel limits, the order is palletized, or the destination has a dock and the carton count is high.

What is the heaviest parcel USPS, UPS and FedEx accept? USPS publishes a 70 lb maximum; UPS and FedEx publish 150 lb maximums for standard services.

Can distributors rate shop cartons across carriers? Yes; GoatLabels shows USPS, UPS, FedEx and DHL quotes side by side for every carton, with no monthly fee.

How do ERP orders get into a parcel queue? By bulk CSV import with header aliasing or through the REST label API with one Bearer header.
