Understanding Inbound Freight (Without Getting Lost in the Details)

Inbound freight isn’t glamorous, but it’s one of the biggest levers on your margin and your sanity. Get it right and your goods land on time, your 3PL can receive quickly, and cash doesn’t evaporate on preventable fees. Get it wrong and you’ll feel it in delays, damaged inventory, and line items you didn’t see coming.

When one of my brands launched just before the pandemic, I went from never booking a container to negotiating ocean freight in the most chaotic market I’d ever seen. I built myself a simple operating outline to avoid expensive mistakes. This is the short, practical version of that outline.

The freight math that drives every decision

Before you book anything, you need two numbers: how much space your goods take and how they’ll ride.

1) Calculate CBM

Freight volume = (Length × Width × Height) × Quantity. Convert to cubic meters (CBM). This number drives container choice and pricing.

2) Pick your container and load strategy

  • 20' container: better for dense, heavy cargo; roughly 9–10 pallets per tier.

  • 40' container: better for volume; roughly 20 pallets per tier.

  • 40' high‑cube: adds one foot of height for bulky items.

Usable capacity is rarely 100%. Plan on ~80% once you account for packaging, bracing, and safe stacking.

FCL vs. LCL (rule of thumb)

  • Choose FCL around 12–15 CBM or higher when reliability matters and you want fewer touchpoints.

  • Choose LCL when you’re light on volume and flexible on timing; expect higher cost per CBM and more handling risk.

Palletized or floor‑loaded: the real trade

  • Palletized: faster to unload at the 3PL, cleaner inventory control, lower damage risk; freight cost is higher because pallets add weight and volume.

  • Floor‑loaded: cheaper per shipped unit; slower and more expensive to receive, higher risk of damage.

Founder note: if your product is fragile, high‑value, or has strict carton orientation, palletize. One “cheap” floor‑loaded container that arrives with crushed corners will erase whatever you saved on freight.

Customs bonds: the small checkbox that stops big delays

If you’re importing into the U.S., a customs bond guarantees duties, taxes, and fees will be paid.

  • Single‑entry bond: one shipment; typical cost ranges from roughly 50 to 150 dollars depending on value.

  • Continuous bond: covers all shipments for a year; generally worth it once you’re shipping monthly or moving higher values.

As of May 2025, the U.S. removed the 800‑dollar de minimis threshold for shipments from China and Hong Kong. Even small parcels can now trigger duties and bond requirements. Plan accordingly.

Ask your partner every time:

  • Do I need a bond for this shipment?

  • Who is arranging it?

  • Which HTS code are you applying to my product?

Insurance: don’t ship without it

Marine cargo insurance is the only reliable way to protect inventory in transit.

  • All‑Risk: broad protection against most loss and damage; recommended when possible.

  • Named Perils: only listed risks (fire, sinking, collision).

  • FPA (Free of Particular Average): major losses only.

Founder note: carriers’ default liability is not a safety net. If the vessel declares General Average, you can be billed to help “save the voyage” unless you’re properly insured.

Where invoices jump: fees to watch

  • Demurrage: container sits at port beyond free time.

  • Detention: container kept too long after pickup.

  • Drayage: short‑haul trucking from port to your 3PL.

  • 3PL receiving: fees spike when pallets miss spec (height, wrap, slip sheets, labeling).

A quick example: a founder skipped slip sheets, assuming the warehouse would unload anyway. The 3PL paused receiving and re‑palletized at hourly rates. The shipment was fine; the invoice wasn’t.

Build a buffer. Add 10–15 percent to your inbound freight budget for port and handling variance. It’s cheaper than pretending variance won’t happen.

Make your 3PL’s job easy

Every 3PL has a receiving spec. A typical baseline:

  • Four‑way 48" × 40" pallets in good condition

  • Loaded height in the mid‑50‑inch range (including pallet)

  • Pallet wrap covering the entire load and pallet

  • Slip sheets between cartons and pallet, plus on top

  • Carton labels facing out; mixed pallets clearly marked and content listed

Hit their spec and you’ll cut receiving time, reduce miscounts, and avoid “special handling” charges.

A simple checklist you can copy

1. Calculate CBM and sanity‑check actual usable container capacity (~80%).

2. Choose FCL vs. LCL based on volume, timing, and risk tolerance.

3. Decide palletized vs. floor‑loaded with receiving cost in mind.

4. Confirm Incoterms so cost and risk are clear at each stage.

5. Secure the right customs bond and verify HTS codes.

6. Buy cargo insurance that fits your risk (All‑Risk if you can).

7. Align to your 3PL’s receiving spec (pallet height, labeling, slip sheets).

8. Add a 10–15 percent buffer for demurrage, detention, and drayage variance.

Quick FAQs

When should I switch from LCL to FCL?

Around 12–15 CBM, the math often tips to FCL once you include reliability and reduced damage claims. If you’re shipping on a cadence, FCL scheduling also reduces “wait to fill” delays.

Do I really need cargo insurance?

Yes. The cost is modest relative to the risk. All‑Risk coverage makes the most sense for most consumer goods.

Which Incoterms show up most for DTC?

FOB and CIF are common for ocean freight. Know exactly when title and risk transfer, and who pays what. Misunderstanding Incoterms is a quick way to pay for problems you didn’t plan for.

Mini glossary

  • CBM: cubic meters; core input for ocean freight pricing.

  • FCL / LCL: full container load vs. shared container space.

  • Incoterms: rules allocating cost and risk between buyer and seller (FOB, CIF, DDP).

  • Demurrage: fee when a container sits at port beyond free time.

  • Detention: fee when a container isn’t returned on time after pickup.

  • Drayage: short‑haul move from port to warehouse or 3PL.

  • General Average: maritime principle where cargo owners share certain emergency costs.

Inbound freight is an operating system choice, not just a booking. Do the math up front, decide how your goods will ride, protect the shipment legally and financially, and meet your 3PL’s spec on arrival. The result is fewer surprises, faster receivings, and healthier contribution margins.
