Quick Answer
FOB and DDP are two of the most common shipping terms (Incoterms) in supplement OEM quotes, and they determine two very different things: who pays for freight, insurance, and customs duties, and at what point responsibility for the goods transfers from seller to buyer. Under FOB, the buyer takes over once goods are loaded onto the shipping vessel at the origin port — the buyer arranges and pays for everything after that. Under DDP, the seller handles the entire journey, including customs clearance and duties, and delivers the goods to the buyer's specified address. Neither term is inherently "better" — the right choice depends on whether you have your own freight forwarder and customs experience, or you'd rather pay a bit more for a single, predictable landed cost.
Why This Matters More Than It Seems on a First Order
For first-time supplement brands, Incoterms are often the least-understood line item on a quote — but getting this wrong is one of the most common sources of unexpected cost surprises. A quote that looks cheaper on an FOB basis isn't actually cheaper once freight, insurance, customs brokerage, and import duties are added — those costs simply move from the seller's quote to the buyer's own arrangements. Understanding this upfront prevents the common mistake of comparing an FOB quote from one supplier directly against a DDP quote from another, which isn't an apples-to-apples comparison.
FOB (Free on Board): What It Actually Means
- The seller is responsible for the goods, export customs clearance, and loading them onto the vessel at the origin port (commonly a Chinese port for supplement OEM shipments).
- Once the goods are loaded onto the ship, responsibility and risk transfer to the buyer.
- The buyer arranges and pays for ocean/air freight, marine insurance (if desired), destination customs clearance, import duties, and final delivery to their warehouse.
- FOB typically results in a lower quoted unit price from the manufacturer, since freight and import costs aren't included — but the buyer needs either their own freight forwarder or a working relationship with one.
DDP (Delivered Duty Paid): What It Actually Means
- The seller is responsible for the entire journey: export clearance, freight, import customs clearance, and payment of import duties, all the way to the buyer's specified delivery address (often a fulfillment center, such as an Amazon FBA warehouse).
- The buyer's responsibility begins only once the goods arrive at the agreed destination.
- DDP typically results in a higher quoted total price, since freight, insurance, and duties are built into the number — but it gives the buyer one predictable landed cost with no customs paperwork to manage themselves.
Which Should a First-Time Buyer Choose?
- Choose DDP if: this is your first import, you don't have an existing freight forwarder or customs broker relationship, or you want a single predictable number to plan your margins around — this is especially common for smaller pilot orders and first-time Amazon FBA shipments.
- Choose FOB if: you already import regularly, have an established freight forwarder, and want more control (and potentially lower cost) over the shipping and customs process — this is more common for repeat buyers and larger, recurring orders.
Other Incoterms Buyers May See
- EXW (Ex Works) — the buyer takes responsibility from the seller's factory door, including arranging pickup; rarely used for first-time buyers since it requires the most logistics knowledge.
- CIF (Cost, Insurance, and Freight) — similar to FOB but the seller also arranges and pays for freight and insurance to the destination port; the buyer still handles destination customs clearance and delivery.
Questions Worth Asking a Manufacturer Before Choosing
- Is the freight cost on a DDP quote a firm number, or an estimate subject to adjustment based on actual shipment weight? (Freight rates fluctuate, so many DDP quotes are estimates that get reconciled after the actual shipment weight is confirmed.)
- Does the DDP quote include import duties for your specific product category and destination country, or only freight and customs clearance fees?
- If choosing FOB, does the manufacturer have experience preparing export documentation your freight forwarder will need (commercial invoice, packing list, certificate of origin)?
- For destination-specific compliance (labeling, registration) — is that the buyer's responsibility regardless of which Incoterm is used? (It generally is — Incoterms govern shipping and customs cost responsibility, not product compliance.)
Buyer Checklist
- Have you confirmed which Incoterm a quote is based on before comparing it to another supplier's quote?
- If choosing DDP, have you confirmed whether the freight portion is a firm number or a weight-based estimate?
- If choosing FOB, do you have a freight forwarder relationship in place, or a plan to establish one?
- Have you separately confirmed product compliance requirements for your destination market, since this isn't covered by the Incoterm itself?
Frequently Asked Questions
What's the main difference between FOB and DDP? FOB means the buyer takes responsibility for the goods once they're loaded at the origin port and arranges their own freight, insurance, and customs; DDP means the seller handles the entire journey, including import duties, delivering to the buyer's specified address.
Is DDP always more expensive than FOB? The quoted unit price is typically higher under DDP because freight, insurance, and duties are built in — but the total landed cost may be similar once an FOB buyer adds their own freight and customs costs. The real difference is who manages the logistics and where cost certainty sits.
Which Incoterm should a first-time Amazon FBA seller use? DDP is common for first-time FBA shipments, since it delivers directly to the fulfillment center with duties and customs already handled, removing the need for the buyer to manage import logistics themselves.
Does the Incoterm affect product compliance requirements? No — Incoterms govern who pays for and manages shipping, customs, and duties. Product compliance (labeling, registration, market-specific claims rules) is a separate responsibility that applies regardless of which Incoterm is used.
Why do DDP freight quotes sometimes change after the order ships? Freight rates can fluctuate between quoting and actual shipment, so many DDP quotes are provided as an estimate based on projected weight, with a final reconciliation (refund or additional charge) once the actual shipment weight is confirmed.
