China → USA Oversized Cargo

The US lane runs three oversized channels, and they are not interchangeable. Sea flat-rack and open-top handle the heavy and the wide; air BUP handles the urgent and the fragile; UPS heavy air handles the pieces that are too big for a parcel but too small to charter. Picking the wrong one usually means the cargo gets re-packed, or refused at the gate.

All three are quoted DDP door: we clear on our own US customs BOND, prepay duty, and deliver with our own truck fleet plus crane or dock where the site needs it. Send a photo, a drawing and the L×W×H plus weight per piece, and we will confirm which channel physically accepts the cargo before we talk price.

Sea Oversized — Flat Rack & Open Top

The cheapest way to move heavy or over-width cargo to the US, and the only channel that scales to hundred-tonne pieces. Sailings from Yantian to Los Angeles, Long Beach, New York and Savannah.

EquipmentUsable PlatformPayloadBest For
20 ft Flat RackAbout 5.7 m × 2.2 mUp to about 30 tCompact heavy pieces, skids, compact machinery
40 ft Flat RackAbout 12.0 m × 2.0 m between postsUp to about 45 tLong machinery, steel structures, over-width loads
40 ft Open TopAbout 12.0 m × 2.3 m, roof removedUp to about 26 tOver-height cargo that still fits inside the posts
Break-bulk / heavy liftQuoted per shipment100 t and above per pieceTransformers, reactors, wind components

Transit 25–45 days port to port depending on carrier and discharge port; Matson CLX oversized truck to Long Beach is the fastest sea option. Inland over-width movement in the US needs a state permit and sometimes an escort — we arrange both.

Air Oversized — BUP

BUP lets cargo that breaks normal air pallet limits still fly. It is the right channel when the piece is urgent, valuable, or too delicate to survive a sea voyage — not when it is merely large.

ParameterTypical LimitNotes
Length per pieceUp to about 6 mLonger pieces need a special arrangement and a specific aircraft
Weight per pieceUp to about 5 tAbove this, loading equipment and aircraft type become the constraint
Transit to ORD / LAX / JFK7–12 days door to doorIncludes US clearance and inland delivery under DDP
PackingWooden crate or steel frame, shock and moisture protectionNude lashing is possible for some pieces; we assess the lifting points first

BUP is priced per shipment, not per kilo, because the cost driver is aircraft capacity and special loading rather than weight. Send the drawing and we will tell you whether it flies before you commit to packing.

UPS Heavy Air

For single pieces that clear the carrier's size and weight rules but exceed normal parcel limits, UPS heavy air is often cheaper and simpler than a full BUP arrangement — no charter negotiation, no special handling fee, and it tracks like a parcel.

ParameterTypical LimitNotes
Weight per pieceUp to 2,000 kg (2 t) per pieceSingle pieces beyond the parcel ceiling move on UPS heavy air without charter negotiation
Longest sideUp to 3.9 m (about 153 in)Very long pieces are accepted — we pre-check handling at both airports
Delivery8–12 days door delivery nationwideCovers all US destinations; faster than sea, cheaper than BUP for pieces within limits
PackingExport crate with drop protectionMust survive automated sorting equipment

UPS applies published weight and size limits per service. Send the carton dimensions and weight and we will confirm which UPS service accepts your piece and whether a surcharge applies.

Which US Channel Fits Your Cargo

Your CargoRecommended ChannelWhy
Heavy and wide, delivery date is flexibleSea Oversized — Flat RackLowest cost per tonne; the only channel that scales past 45 t
Over-height but inside the container postsSea Oversized — Open TopKeeps the standard container rate while clearing height that a GP cannot
Urgent, high value, or too delicate for a sea voyageAir Oversized — BUPFastest route for genuine out-of-gauge pieces
One piece up to 3.9 m / 2 t, no rush inside two weeksUPS Heavy AirParcel-like tracking and simpler handling than BUP
Multiple pieces, mixed sizes, one delivery dateSea oversized plus Air BUP for the critical pieceWe split the shipment so only the piece that has to fly, flies

If two channels are both technically possible, the decision is almost always transit versus packing cost — not freight rate.

FAQ — Oversized to the USA

Cargo We Accept for Oversized DDP

Our oversized DDP program regularly moves four standard categories of out-of-gauge freight:

Crated Goods (Wooden Case)

Precision instruments and industrial equipment packed in shock-absorbing, moisture-resistant wooden crates.

Flight Cases

Touring and exhibition gear, as well as instrument cases — moved via the air BUP channel or by ocean.

Timber-Framed Cargo (Wooden Frame)

Machine components and metal structures secured with custom timber framing.

Palletized Loads

Stretch-wrapped, labelled pallets, accepted for FCL, LCL or air shipments.

Every category above ships under DDP — delivered duty-paid to your door anywhere in the continental United States (all 48 states).

What is the largest piece you can ship to the US?

By UPS heavy air, up to 3.9 m and 2 t per piece with 8-12 day nationwide delivery. By air BUP, up to about 6 m and 5 t per piece. By sea flat-rack, up to about 12 m on a 40 ft frame with roughly 45 t payload, and break-bulk or heavy-lift beyond that. The real ceiling is usually the US inland leg, not the ocean voyage.

Sea or air for oversized cargo to the US?

Sea if the delivery date is flexible and the piece is heavy — flat-rack is far cheaper per tonne. Air BUP if the piece is urgent, high value, or too delicate to survive weeks at sea. Send the drawing and we will price both.

Can oversized cargo still go DDP to the US?

Yes. Sea and air oversized both run DDP: we clear on our own US customs BOND, prepay duty, MPF and HMF, and deliver to your site. Rail and truck oversized are not offered on the US lane.

What do you need from me to quote an out-of-gauge shipment?

Name and description of the cargo, a photo or drawing, L×W×H in metres, weight in tonnes, number of pieces, origin, delivery address with ZIP, and whether the piece has marked lifting points.

Can you deliver inside my factory or onto a foundation?

Yes. Our own US truck fleet plus partner heavy trucks can lift to the exact spot, including truck with crane or a dock leveller where the site requires it. Tell us the access constraints — gate width, ground bearing, overhead lines — at quoting stage.

Who is responsible if the cargo is damaged in transit?

Professional lashing and supervised loading are standard, and we arrange all-risk cargo insurance on request. Because consolidated sea cargo is handled more than once, we recommend insurance on LCL and on any piece that cannot be replaced quickly.

Which commodities qualify for your oversized DDP service?

Primarily four types — crated goods, flight-case shipments, timber-framed cargo and palletized loads — each one shipped duty-paid to the destination door.
