37 Q: What is the price difference among EXW, FOB, CIF, DDP?
EXW- Ex Works FOB - Free On Board CIF - Cost Insurance and Freight DDP - Delivered Duty Paid
One of the big reasons this is the most popular intercom term used that the Export port is a good place to have a 3rd party inspection service inspect the goods. Further, the seller is responsible for all activities in the country of export. Simultaneously, the Buyer is responsible for all activities once the goods leave the country, making things simple. Besides, most freight forwarders will have an office at or near the port, and it’s an easy spot for them to pick up the goods on your behalf.
We often get asked, why don’t you get every project DDP? I will say it is the easiest for the buyer, but it will not be the cheapest. The Seller is the one that picks the shipping company and will choose the one they like best and not the cheapest or most reliable. You are putting a ton of trust in the shipping company. If you want, I would suggest you get a quote for DDP from your supplier, then get a quote for FOB and a quote from a freight forwarder and compare the two's final total price.
EXW- Ex WorksThis is the most basic shipping intercom term that a supplier can provide. The seller makes the item available to pick up at the factory and is not responsible for the product once it leaves the factory doors. The buyer is responsible for transporting it from the factory and covers all export and import clearances and insurance costs. If you are getting initial quotes from a factory for the first time, then they will almost always give you a quote for EXW unless you explicitly ask for a quote in another term. The reason factories and supplier quotes in EXW is simply because it’s the lowest price for them, and it looks good when you're comparing quotes, and you need the lowest price.
FOB - Free On BoardFOB means that the seller ships the goods to the nearest port, and the seller is responsible for everything after that. The Seller will drop this off at the port of shipment, and the Buyer will either pick it up themselves or more commonly work with a freight forwarder to ship it for them. The seller is the one to clear the goods for export, and the buyer is responsible for the goods from the port onwards. It’s vital when getting FOB quotes to make sure that you get the port's name that they are dropping the goods off at.
CIF - Cost Insurance and FreightEffectively similar to the one above except that the buyer will require the seller to take on the risk or obtain insurance on the good until the destination port. The seller bears all costs of shipping and assumes the risk of the goods until the destination port. The seller is also responsible for clearing customs, but the buyer is responsible for paying the duty. Again this is effectively the same as CIP, except CIF is specifically for water.
DDP - Delivered Duty PaidIn these terms, this means that the seller pays for and is responsible for everything. The seller pays all costs and assumes all risks to the final destination. The buyer is only responsible for unloading the goods once they arrive at the final destination as chosen by the buyer.
38 Q. What happens if testing fails once we received the parts and what is the procedure on that?
A:Our normal procedure is, if there is no problem with price and other matters, we would send you some samples first, if there is no problem with it too, we would start to mass process, and give QC 100%.
Of course, If there is a third party come to our company to make the inspection, we would coordinate it.
And if there is a problem with a product, We would confirm if could be repaired again first, if not, we would produce a new product again and assume the cost.
