Ocean vs Air Freight for Apparel: The Real Cost Per Garment

Freight is the one line in an apparel cost sheet where the same garment can cost ten times as much depending on a decision made three months earlier. This page does the per-garment arithmetic both ways, with the rate tables, transit times and terminal charges behind it, as of August 2026. It sits inside our guide to landed cost for apparel imports, which assembles freight, duty and fees into one number.

We looked at this from the data side first. Yarnstick's shipment-level analysis of US import bills of lading — air and sea, trailing twelve months, every consignee classified individually — shows thousands of small, frequent air shipments from brands replenishing in urgent batches at air-freight premiums. That is not an exotic edge case. It is the default operating mode of a small importer without a forecast, and it is precisely the pain a forecast-ahead, ship-by-sea model converts into margin.

The per-garment math: what ocean and air cost on the same tee

Basis: 10,000 cotton jersey crew tees, 180 gsm, FOB $4.30 a unit ($43,000), Asia to the US West Coast, August 2026. Freight figures are volatile and dated; the surcharge midpoints are industry ranges, not a quote.

A packed tee weighs about 0.23 kg — roughly 0.20 kg of finished garment plus polybag, carton and dunnage. Ten thousand of them is 2,300 kg of actual weight, and well under half a 40ft high cube.

The two columns are not symmetrical, and the asymmetry runs against air. The ocean columns carry $900 of US drayage from port to DC; the air column carries no equivalent, because airport ground handling, customs-side terminal charges and the trucking leg from the airport to your DC are not modelled here. Those charges are real and are billed on every air shipment, so the true air-versus-ocean gap is wider than this table shows, not narrower.

Even on the table as it stands, air costs $12,140 more than structural ocean on a $43,000 order — 28% of the FOB value of the goods, spent on speed. On a garment carrying a typical wholesale margin, that is the entire margin on the style.

Why ocean freight per unit depends on how full the container is

The 12.0% figure above looks worse than the $0.15-0.30 a unit quoted at the top of this page, and the difference is the single most useful thing to understand about ocean freight: you rent the box, not the space you use.

A 40ft high cube holds roughly 20,000-25,000 folded and polybagged tees. Fill it at the structural rate and freight is about $0.19 a unit, 4.4% of FOB, inside the $0.15-0.30 structural, non-peak per-unit range quoted at the top of this page. Put 10,000 tees in the same box and the identical freight bill spreads over less than half the units, so it doubles to $0.43 a unit before drayage.

Fill is one basis; the rate you booked on is the other, and the two ranges must never be mixed. On the 11 August 2026 spot assessments of $7,400-9,400 per FEU, the same full box works out at $0.30-0.47 a unit — that is a dated peak-spot basis, not a budgeting number. Any per-unit freight figure you carry in a cost sheet should say which of the two it is: $0.15-0.30 structural and non-peak, $0.30-0.47 at the August 2026 peak spot, both assuming 20,000-25,000 tees in the container.

Air freight has no such economy. It is billed per kilo, so the per-unit cost is flat whatever the order size — $1.38 a unit at 500 pieces and $1.38 a unit at 50,000. The strategic consequence is straightforward: ocean rewards consolidation and air does not, which is why a brand that can forecast one large sea shipment instead of four small air shipments wins twice, on rate and on fill.

Ocean freight rates: structural ranges against August 2026 spot

The table below shows structural, non-peak ranges suitable for annual budgeting. These are contract-planning numbers, not today's market.

The table below shows published spot assessments. These are snapshots and move weekly. August 2026 is an unusually elevated and extended peak season — do not budget from these numbers.

Freightos FBX and Drewry WCI are different baskets built on different methodologies. Track one, and do not mix them in a single chart or a single budget.

One structural caveat sits over every India, Pakistan and Bangladesh lane into the US East Coast: carriers have partially restarted Red Sea transits as of August 2026, but attacks extending to Bab el-Mandeb and Saudi Red Sea ports keep routing unstable. Red Sea routing is currently the single biggest swing factor on both transit time and rate for those lanes.

Transit times from Asia to the US, port to port

The table below shows port-to-port ocean transit. Full container door-to-door adds 7-15 days; LCL door-to-door adds substantially more.

By air, count 18-24 hours of flight time plus 4-8 hours of ground handling each end: 2-4 days door to door on express, 3-7 days on standard service from Vietnam or India. Deferred or economy air saves 20-30% against priority and costs a day or two. That last option is chronically under-used by brands who book priority air by reflex.

These numbers belong in your replenishment model, not in a spreadsheet cell labelled "shipping" — see reorder points when lead time is 90 days.

FCL or LCL: the crossover sits around 14-15 CBM

Below roughly 14-15 CBM, less-than-container-load is cheaper. Above it, a full 40ft container wins, and a 40ft high cube offers about 68-76 CBM of capacity.

LCL has two costs that do not appear in the per-CBM rate. It is slower, because your cargo waits for consolidation at origin and deconsolidation at a container freight station in the US: HCMC to Los Angeles runs 28-35 days door to door LCL against 18-22 days port to port FCL, and HCMC to New York 38-48 days. And it is handled more, which for polybagged apparel means more crushing, more moisture exposure and more mis-sorts. Also watch the minimum charges — $120-140 per shipment on the lanes above — which make very small LCL bookings expensive per unit.

Chargeable weight and the 6,000 cm³/kg divisor: why apparel volumes out

Air freight is billed on chargeable weight: the greater of actual gross weight and volumetric weight. Volumetric weight uses a 6,000 cm³/kg divisor, which is the same as saying 1 CBM = 166.67 kg.

Work a typical export carton. A 60 × 40 × 40 cm carton is 96,000 cm³, which divided by 6,000 is 16 kg volumetric. If that carton holds 60 tees at 0.23 kg each, the actual weight is 13.8 kg. You are billed on 16 kg — a 16% uplift you never see in the quote.

Apply that uplift to the worked example above and the 2,300 kg shipment bills as roughly 2,667 kg, taking the air total from $17,290 to about $20,040, or $2.00 a unit, 47% of FOB. Folded, polybagged apparel in cartons routinely volumes out this way, and heavier styles do not: a 320 gsm hoodie at roughly three times a tee's weight is far more likely to bill on actual weight. Ask your forwarder to quote chargeable, not actual, weight and to state the divisor.

Drayage, demurrage and detention: the costs that begin when the vessel arrives

The table below shows typical 2026 US drayage and terminal charges per container.

Worked drayage example: one 40ft container out of Port Newark, 20 miles inland. Line-haul $450, fuel surcharge $216, chassis $90, tolls $30 — $786 clean. Add a missed appointment, an extra chassis day and driver waiting time, and the same move bills at $1,636 or more. The delta is not a rate problem, it is an appointment and warehouse-readiness problem.

Two related charges start their clock at arrival. Demurrage applies while a loaded container sits inside the terminal past free time. Detention, or per diem, applies while the container is outside the terminal past free time. Free time typically runs 3-7 days for demurrage and 4-7 days for detention, carrier and port specific. North American daily rates are the highest in the world, averaging around $138/day, with demurrage commonly $100-500/day and detention $100-200/day — and the tiers escalate, so days 8 and beyond can bill at two to three times the day 1-3 rate. A container held for a CBP exam accrues these charges while it waits, which is why exam risk and demurrage risk should be modelled together with the MPF, HMF and entry-side fees.

Booking around Chinese New Year, Tết, Eid and Diwali

Freight rates are seasonal, but the harder constraint is factory and port capacity around fixed holidays. Chinese New Year removes 2-4 weeks of effective capacity in January and February, with a rate and space crush beginning weeks before it. Vietnam's Tết costs 1-2 weeks and bookings need to go in 3-4 weeks ahead. Bangladesh has two Eid holidays a year of roughly 1-2 weeks each. India loses working time around Diwali.

Put these in the ship window rather than the safety buffer. A shipment that needed to leave in the second week of Tết is not late by a week — it is late by a week plus however long the post-holiday backlog takes to clear. The sampling calendar that sets your ship window is where that planning starts, and origin choice changes which holidays bind, which is covered in comparing India, Vietnam, Bangladesh and China.

What to ask an apparel freight forwarder before you book

Every figure above is quotable, which means it is also checkable. The six questions below turn a forwarder's quote into something you can compare against another forwarder's quote and against the cost sheet.

• Is the rate all-in? Ocean quotes on the structural ranges above generally include terminal handling and fuel; air quotes above do not, and the surcharges added $3,490 to the $13,800 base in the worked example.
• What chargeable weight and divisor are you billing on? Ask for chargeable rather than actual weight and have the 6,000 cm³/kg divisor stated, because folded apparel in a 60 × 40 × 40 cm carton bills at 16 kg against 13.8 kg actual.
• How many days of free time do I get? Demurrage free time typically runs 3-7 days and detention 4-7 days, and both are carrier and port specific, so the number belongs in the booking, not in an assumption.
• What is included in drayage? Line-haul, fuel surcharge at 35-55 percent of line-haul, chassis at $35-75 a day and tolls are separate lines; the Port Newark example runs $786 clean and $1,636 with delays.
• What routing are you using? On India, Pakistan and Bangladesh lanes into the US East Coast, Red Sea routing is the single biggest swing factor on both transit time and rate as of August 2026.
• At what CBM would you put me in a full container? An apparel freight forwarder that answers "around 14-15 CBM" is using the same crossover this page does.

An apparel freight forwarder is not the same as a general forwarder with an apparel account: the useful ones already know that polybagged garments volume out on air, that LCL deconsolidation at a CFS crushes cartons, and that a container held for a CBP exam accrues demurrage while it waits.

When air freight is actually the right call

Air is not always wrong. It is right when the value of arriving on time genuinely exceeds 30-45% of FOB:

• A launch or collaboration with a fixed public date, where late means no sale at all.
• A seasonal category with a short selling window, where three lost weeks means markdown rather than full price.
• A partial airlift: fly enough units to open the season, sail the balance. This is usually far cheaper than flying the whole order and is the single most under-used tactic in apparel freight.
• A quality failure caught at final inspection where the replacement run must land before the drop.

What air is not is a substitute for a forecast. If your freight mix is drifting toward air across multiple seasons, the problem is upstream in planning and factory lead time, not at the airport. The freight decision also interacts with the commercial terms you buy on, which is covered in which Incoterm to buy on, and every term used here is defined in the Yarnstick glossary of freight and customs terms.
