China Sourcing Logistics Guide — FCL, LCL, Choosing a Forwarder, and Sea vs Air
The goods are made — but you get stuck bringing them in

Hello, this is GreenFrog Seoul.

"I negotiated a great ex-factory price, but once it landed, freight plus surcharges wiped out my margin."
"They told me LCL was cheaper, so I chose it — then the destination charges came in higher than the freight itself."
"The forwarder said 'no problem,' but I only found out at customs that the paperwork was incomplete."

Plenty of sellers clear the sample stage and finish production, only to get tripped up at the final gate: logistics. Treat international logistics as a mere "cost of moving goods" and you fall into traps. Logistics isn't just delivery — it's a pillar of the deal that shapes your final cost as much as the factory price does, draws the line of liability, and dictates your lead time. Choose by freight rate alone, and unseen surcharges and delays eat your margin.

Logistics isn't where you decide "how to ship." It's where you decide "where my responsibility ends and what my true cost really is." One shipping mode, one line of Incoterms, one forwarder — these choices pre-determine the cost and the liability for accidents after arrival.

Today, drawing on years of bringing in cargo for Korean sellers, GreenFrog Seoul lays out an 8-stage guide from choosing a shipping mode to managing a forwarder. The sea-vs-air fork, the FCL-vs-LCL criteria, how to pick a forwarder, the liability split set by Incoterms, and the surcharges that never appear on the rate sheet — all distilled into practical steps you can use on your next shipment.

1. Why Logistics Is Your Second Cost

Once the order is placed, it feels like you can relax — but your margin shifts again at logistics. No matter how well you cut the ex-factory price, get freight and surcharges wrong and the landed unit cost becomes a completely different number. If the factory price is "the value of the product," logistics is "the cost of getting that value to your warehouse." Only by adding the two do you see your true cost.

Pick the cheapest by freight rate alone, and the hidden costs all land at once at the destination port. Understand the structure first, and you can compare a true total cost — freight, surcharges, and customs bundled together.

2. Sea or Air — The Triangle of Weight, Volume, and Time

The first fork is whether to send by sea or by air. The right answer differs by product. Weight, volume, and how urgent it is — these three interlock to set the answer.

Sea vs Air at a Glance

Four Principles for Choosing a Mode

• Weigh both volumetric weight and actual weight — even if light, bulky cargo is billed by volumetric weight in air freight
• Judge by freight as a share of unit price — low-value, high-volume usually favors sea; high-value, low-volume often favors air
• Plan backward from the sale date — for seasonal goods, a few days' delay can blow a whole season
• Use air only when urgent; keep sea as the default — make air routine and your margin won't survive

3. FCL or LCL — A Whole Container, or Shared?

Once you've decided on sea, the next fork is whether to use a whole container (FCL) or share one with other shippers (LCL). Sellers with in-between volumes find this the most confusing point, but the criterion is surprisingly simple.

FCL vs LCL

Four Principles for FCL/LCL

• Consider FCL once volume exceeds half a container — in-between amounts can flip on LCL surcharges
• Compare LCL on total cost, not freight — destination handling often exceeds the freight
• Factor consolidation risk for fragile cargo — mixing with others' goods raises damage odds
• Watch for the point to switch to FCL as you grow — as order volume rises, per-unit freight is cheaper with FCL

4. Choosing a Forwarder — The Partner You Hand Your Logistics To

A freight forwarder handles shipping, customs, and paperwork, taking your cargo all the way to the door. Find a good one and logistics runs invisibly; pick the wrong one and every shipment becomes a string of accidents. That's why the first choice matters so much.

Criteria for Choosing a Forwarder

Four Principles for Forwarders

• Get quotes itemized — not "all-in," but freight, surcharges, and customs separately
• Ask about route track record — the more they run China→Korea, the more stable
• Test with a small shipment first — sync up once before handing over big volume
• Watch how they handle problems — their attitude in a crisis is the real measure of skill

5. Incoterms — The One Line That Splits Liability

Abbreviations on a quote like EXW, FOB, CIF, and DDP are Incoterms (trade terms). This one line sets "where factory responsibility ends and yours begins." Skip past it and, when an accident happens, you get a stretch no one is responsible for.

Common Incoterms

Four Principles for Incoterms

• Always confirm the Incoterm on a quote — the same unit price means a wildly different total by term
• As a beginner, master FOB first — the liability split is clear, making comparison and management easy
• With EXW, beware hidden inland costs — you bear the full cost from factory to port
• With DDP, check the breakdown despite the convenience — all-inclusive can look expensive, but variables are few

6. Surcharges — The Real Costs the Rate Sheet Hides

Half of all logistics trouble comes from not knowing the surcharges. Freight is one line, but the costs that attach as the cargo passes through ports to your warehouse run in several streams. The names sound foreign, but once you know the structure you gain an eye for reading a quote.

Typical Surcharges

Four Principles for Surcharges

• View quotes as a total including surcharges — comparing on one freight line is always wrong
• Pay special attention to destination charges — surprise billing is more common at the destination than the origin
• Calculate duty and VAT in advance — check the rate by HS code and reflect it in cost (see Ep.24)
• Ask about unexpected items on the spot — if an unfamiliar abbreviation appears, confirm before it's billed

7. Lead Time and Risk — Time Is a Cost Too

In logistics, time matters as much as money. Skimp on freight and miss your deadline, and you lose a sales opportunity worth more than the freight you saved. Seasonal goods especially — a few days' difference decides a whole season's revenue.

Variables That Shake Lead Time

Four Principles for Lead Time and Risk

• Plan backward from the sale date — add customs and inland transport time to the target arrival date
• Leave slack before peaks and holidays — move several weeks earlier around Chinese New Year
• Insure high-value cargo — a fraction of the freight wards off a large loss
• Don't depend on a single forwarder — keep a second option for emergencies

8. Customs Connection — Arrival Isn't the End

The ship reaching port doesn't mean the job is done. Only after clearing customs does the cargo truly become yours. Get stuck at customs and it sits at the port while storage charges pile up daily, so logistics and customs must be prepared as one package.

What to Cover at Customs

Four Principles for Customs

• Confirm HS code and import requirements before shipping — check before departure, not after arrival
• Match documents exactly to the goods — mismatched amount, quantity, or name gets you stuck
• Secure an FTA certificate of origin to save duty — for Korea-China FTA items, the rate changes greatly (see Ep.24)
• Sync with forwarder and broker early — share from the shipping stage, not just before arrival

9. GreenFrog Seoul's Logistics Support

Much of today's 8-stage guide a seller can judge alone once they understand the structure. But comparing forwarders, verifying surcharges, and checking customs documents require a local network and trade experience, so GreenFrog Seoul handles or shares that work.

Wrap-up — Know Logistics, and the Last Margin Remains

Compressing today's 8-stage guide to a line each:

• Stage 1 (nature of logistics): not freight but a second cost — see true cost by adding it to the ex-factory price
• Stage 2 (sea vs air): choose the mode by the triangle of weight, volume, and time
• Stage 3 (FCL vs LCL): drop the myth that LCL is always cheaper; judge on total cost
• Stage 4 (forwarder): pick not the cheapest but the most transparent
• Stage 5 (Incoterms): the one line that splits liability — compare on aligned terms
• Stage 6 (surcharges): add up the real costs the rate sheet hides
• Stage 7 (lead time): time is a cost too — finish a month before Chinese New Year
• Stage 8 (customs): arrival isn't the end — get documents ready before shipping

Logistics is the stretch where a seller finally protects or loses their margin. Get quotes as a "landed-to-door price" rather than a single freight line, align liability with Incoterms, and prepare customs documents before shipping — most of the devices introduced today cost nothing extra and apply from your very next shipment. GreenFrog Seoul works alongside Korean sellers to catch the margin that leaks in logistics, from mode design to forwarder comparison, total-cost quotes, and customs checks. If the goods are made but the path to bring them in feels daunting, reach out before you ship — no pressure.
