EXW, FOB or DDP? Choosing Shipping Terms for Your Injection-Molded Parts

A buyer's guide to choosing Incoterms for plastic injection-molded parts: what EXW, FOB, CIF and DDP each put on your plate, how a China-and-Vietnam moulder changes the options, and the questions to settle before you ask for a quote.

What an Incoterm actually fixes - and what it leaves to you

When you buy plastic injection-molded parts, the unit price on the quote is only the first number. The second number - the one that decides whether the part lands on your dock at the cost you expected - is set by the Incoterm, the three-letter trade term printed next to the price. An Incoterm is not a delivery promise; it is a division of labour and risk between buyer and seller. It fixes, in writing, who books the freight, who pays for insurance, who clears the goods for export, who clears them for import, and who pays the duty. Everything the term does not mention stays yours to arrange.

For a moulded-parts buyer this matters more than for most purchases, because the part is rarely the whole shipment. It travels inside cartons, on pallets, sometimes in a shared container, and the moulder you bought it from may be thousands of kilometres away. A supplier such as DAYIN, a China- and Vietnam-based injection-moulding manufacturer with 30+ years and 100+ machines can ship the same part from either of its plants - which means the Incoterm you choose is not a formality, it is a real lever over cost, control and lead time. Get it wrong and the 'cheap' quote becomes expensive; get it right and the freight, the clearance and the duty all sit with the party best placed to handle them.

This guide walks through the four terms a moulded-parts buyer meets most often - EXW, FOB, CIF/CFR and DDP - and shows how to pick between them, including the twist that arrives when your moulder runs two plants in two countries. The logic below is generic trade practice; the supplier facts cited are taken from the moulder's own published pages, not invented.

EXW - collected at the factory gate

EX Works (EXW) means the seller makes the goods available at its premises - the moulder's warehouse or, for a finished batch, at the gate - and you take over from there. The headline unit price is at its lowest, because the seller has added nothing for freight, clearance or handling. But that low price hides the longest to-do list you will ever inherit: you (or your forwarder) must arrange pickup, export clearance, all international freight, insurance, import clearance and duty. In practice the seller under EXW is not even obliged to load the goods onto your truck.

EXW suits a buyer who already controls the chain - who has a freight forwarder on the ground in the origin country, who can clear exports, and who wants to keep the ocean contract and the carrier relationship in-house. For a first-time buyer in another continent it is a trap, because the export-clearance step alone forces you to find a local agent you have never worked with. The 'saving' on the quote is usually smaller than the cost of coordinating a chain you do not yet understand. Treat EXW as the term you grow into, not the one you start with.

There is also a China-specific wrinkle worth knowing: under EXW the seller does not clear the goods for export. If you are buying from a mainland plant and choose EXW, the burden of export declaration falls on you or your appointed agent. That is a strong reason many China-based moulders prefer to quote FOB instead - it keeps the export leg, which they do every day, in their hands.

FOB - the moulder loads it onto the vessel

Free On Board (FOB) is the term most moulders quote by default, and for good reason. The seller delivers the goods, cleared for export, onto the vessel you have nominated at the named port - FOB Shenzhen, FOB Ningbo, FOB Hai Phong. Risk and cost transfer from the seller to you the moment the cargo passes the ship's rail (or, in container practice, the moment it is delivered into the carrier's custody at the port). From that point the main freight, the insurance and the import side are yours.

FOB is popular because it splits the world cleanly. The moulder does what it is good at - making the part and getting it out of the country - while you keep control of the expensive, controllable part: the ocean contract. That lets you consolidate multiple suppliers into one container, negotiate directly with a carrier or forwarder you trust, and see the real freight rate instead of a bundled mystery number. A one-stop OEM/ODM supplier such as DAYIN's plastic injection-molding service typically offers EXW or FOB, and for a recurring buyer FOB is almost always the more transparent choice.

The only catch is that FOB still leaves you owning the import clearance and duty in your own country, and you need a forwarder at the destination to receive the container and file the entry. If you have that in place, FOB gives you the best combination of supplier simplicity and buyer control. It is the default worth defending unless you have a specific reason to shift the split.

CIF / CFR - the seller pays the ocean freight

Cost, Insurance and Freight (CIF) and Cost and Freight (CFR) look like a gift: the seller books and pays the main carriage to your destination port, and under CIF also arranges minimum insurance. The price you are quoted includes the ocean freight, so the number looks complete. But two things are happening underneath that you should not ignore.

First, risk still transfers at the load port, exactly as under FOB - the seller paying the freight does not mean the seller owns the risk once the cargo is on the water. Second, the freight the seller books is the seller's negotiation, not yours, and it is rarely the cheapest available; the markup is simply hidden inside the unit price. The insurance under CIF is also the minimum institute cargo clause cover, which may be inadequate for precision tooling or high-value electronics embedded in the parts. You gain convenience and lose visibility and control.

CIF/CFR is a reasonable crutch for a small first order when you have no forwarder and no volume to leverage. But as soon as you are shipping a full container regularly, renegotiate to FOB so you can see and control the freight. Paying a bundled, marked-up ocean rate on every container is a silent tax on the whole programme - and it prevents you from consolidating with other suppliers, which is where the real freight savings live.

DDP - delivered, duty paid, to your door

Delivered Duty Paid (DDP) is the opposite end of the spectrum: the seller handles everything, including import clearance and the duty, and delivers the goods to your door in your own country. For a buyer who wants zero logistics involvement, it is tempting - one price, one party, no customs forms. But DDP carries two costs that a careful buyer should weigh before accepting it.

The first is price. The seller must price in the freight, the insurance, the import duty and the last-mile delivery, plus a margin for the risk of getting any of those wrong. You pay for certainty, and you pay for the seller's lack of scale in your market. The second is more subtle: under DDP the seller becomes the importer of record in your country. That can create compliance exposure for them and, depending on jurisdiction, can mean the goods are imported under the seller's name rather than yours - awkward for audits, for IP, and for any future direct importing you might want to do. You also learn nothing about your true landed cost, because every underlying charge is bundled and invisible.

DDP can make sense for a one-off sample batch or for a market you will never import into directly. For an ongoing supply relationship it is usually the worst of the options: the most expensive, the least transparent, and the one that teaches you the least about the chain you are relying on. If a supplier only offers DDP, that is itself a signal about who controls the logistics - and it is not you.

Incoterms at a glance: who owns each leg

The table below is the working summary. For each term it states who clears export, who pays the main freight, who arranges insurance, and who clears import and pays duty. 'Buyer' and 'seller' are the two parties to the contract; 'risk transfers' marks the point at which a loss becomes the buyer's problem rather than the seller's.

Use it as a checklist when you read a quote. If the term and the named place do not match - 'FOB' with no port, or 'EXW' on a quote that also claims to include export clearance - send it back. A precise term with a named place is the single cheapest insurance against a logistics dispute you will ever buy.

Why a China-and-Vietnam moulder doubles your options

A moulder that runs two plants in two countries turns the Incoterm choice from a paperwork detail into a sourcing decision. DAYIN's Vietnam plant in Bac Ninh, established in August 2024 with 90-1200T injection machines, means the same part can be quoted EXW Dongguan or EXW Hai Phong, FOB Shenzhen or FOB Hai Phong. Those are not equivalent: the origin plant changes the export regime, the port, the lead time to the vessel, and - critically - the trade-agreement access of the finished goods.

Vietnam's network of free-trade agreements, including the EU-Vietnam FTA, can make Hai Phong-origin parts land in Europe on a different duty line than the same part leaving Shenzhen. So the Incoterm and the plant are two knobs on the same machine: FOB Hai Phong might beat FOB Shenzhen on landed cost to Rotterdam even if the ex-works unit price is identical, because the freight leg is shorter and the duty is lower. A buyer who treats 'the moulder' as one supplier with one quote misses the point - the dual-country moulder is really two origin options, and the term you pick should follow the destination.

The decision matrix below maps common buying situations to a recommended term. The point is not that one term is 'correct' - it is that the right term follows from how much of the chain you already control and which plant the part comes from.

What to put in the RFQ so the quote is comparable

None of the above helps if the quotes you receive are not built on the same basis. Before you ask a moulder for a price, state the Incoterm and the named place explicitly, fix the currency, and state the annual volume you expect - because the term that is cheapest at one carton is rarely cheapest at one container a week. Ask the supplier to confirm who arranges export clearance and who insures the cargo, and whether the quoted price includes the export documentation or leaves it to you.

Specify the packaging too: carton dimensions, pallet type and stack height decide how many parts fit a container, which decides the true per-part freight. A quote that omits packaging is not comparable to one that includes it, and the gap shows up only after the container is booked. Finally, ask for both an EXW and an FOB figure on the same part from the same plant; the difference between them is the supplier's view of the export-and-port leg, and seeing it tells you exactly what you are taking on if you choose EXW. Two quotes on two bases, from one supplier, is the cleanest way to choose the term with open eyes rather than by habit.
