换单就是换 (SWITCH BILL)。收货人先接到发货方的B/L(BILL OF LADING)，船到达收货方 后，收货人持B/L到船公司指定换单处换取 (DELIVERY ORDER)，整箱货一般都要换取提货单后持提货单 ，交纳 及提货。
hipper拿着外代H.B/L——交银行——开证银行——CNEE——我司代理，代理将M.B/L交回船公司安排放货，通知Consignee去提货(Consignee已在货到前就做好了 手续及交目的港产生的Local Charge及换单费)。
二次换单跟转船没关系的，主要由于发货人那，没直接拿到船公司的MASTER B/L，而是找了货代公司，由货代公司签发HOUSE B/L给发货人，用来在目的港换单造成的。这样就需要收货人在目的港找到H B/L的上的换单代理(即发货人那边，签发H B/L的公司，其在目的港合作伙伴，可能是分公司，也可能是合作公司)，先换取M B/L(一次换单)，再以M B/L向船公司进行换单(二次换单)，然后才能申报，提货(有部分海关可以以H B/L申报)。
What is a Switch Bill of Lading and when and why is it used..??
In the normal course of business you might have come across the term Switch Bill of Lading.. A “Switch” bill of lading is the second set of bill of lading that may be issued by the carrier (or agent) in exchange for the first set of bill of lading originally issued when the shipment was effected..
Why does one ask for or require a Switch bill of lading..?? Switch bills are requested generally when there has been a change in the original trading conditions.. Some of the reasons could be :
- Goods could have been resold and the discharge port has now been changed to another port and this could have occurred as a high-seas sale..
- The seller (who could be an intending agent) does not wish the name of the actual exporter to be known to the consignee in case the consignee strikes a deal with the exporter directly..
- The seller does not want to know the buyer to know the actual country of origin of the cargo so he requests that the port of loading be shown as some port other than the one the cargo was loaded from..
The practice of issuance of switch bills of lading is considered by many,luding Clubs and insurance companies, to be dubious or fraudulent depending upon the reasons why the switch bill of lading is required to be issued..
In order to protect themselves from any possible claims arising out of issuing switch bills of lading, the shipping line/agent have to ensure that
- They are covered by their insurance for issuance of such switch bills of lading
- They should provide their insurance company with the exact reason for the issuance of the switch bill of lading..
- They must have the written authority of the prin al before issuing the switch bill of lading, if the issuing party is acting as agents for a shipping line or principal..
- They must issue the switched bill only after collecting the first set of bills, as the dangers of two sets of original bills in circulation for the same cargo are many..
- The switched set should not contain any information different to that of the original bill of lading, (like incorrect port of loading, or change in the condition and quantity of the cargo).. If switch bills contains misrepresentations, the carrier/agent will be at risk of claims from parties who have suffered a loss because of such misrepresentations..
- If the agent has been asked by the principal to issue the switch bill of lading based on an indemnity from the customer, the agent should ensure to get the wording format from the principal and get the completed indemnity approved by the principal before issuing the switch bill of lading..
It seems to be the concerted view of almost all insurance companies covering exports, that a switch bill of lading issued with any misrepresentation or information contrary to the first set issued, without the express actance and understanding of the buyer is a fraudulent document..
