一、國際快遞怎樣寄最便宜
國內想要寄快遞有以(yi)下(xia)幾種方(fang)式:
一、DHL/FedEx
DHL和FedEx的(de)運輸速度都很(hen)有保證，但是這(zhe)兩家都有一個(ge)缺點就是對于郵(you)寄物品的(de)限制很(hen)多，例如食品、易(yi)碎品等(deng)等(deng)都是不承接(jie)的(de)。運費也很(hen)貴，1kg的(de)包裹大約(yue)需要500RMB左右，很(hen)不劃(hua)算。
二、郵政EMS
EMS能(neng)郵(you)寄的東西有很多，速度雖然比不(bu)上DHL。就是郵(you)寄的費用也有點貴，偶爾會出現丟件的情(qing)況。
擴展資料
EMS國(guo)際快(kuai)遞(di)是鐵定按照貨物(wu)重(zhong)量(liang)（實(shi)重(zhong)）來收(shou)費(fei)的(de)，而DHL、UPS和聯(lian)邦等國(guo)際四(si)大家族是按照實(shi)重(zhong)與(yu)體積重(zhong)量(liang)（長(chang)*寬*高/6000）哪個(ge)重(zhong)就按哪個(ge)來收(shou)費(fei)的(de)。不過DHL、UPS那些每公(gong)斤(jin)的(de)收(shou)費(fei)都要比(bi)EMS打折后每公(gong)斤(jin)的(de)收(shou)費(fei)低不少。
比如寄(ji)(ji)(ji)到英國，一般EMS折后每公(gong)斤要(yao)70元左右(you)，而DHL最便宜的每公(gong)斤45元都(dou)有(you)（限(xian)于(yu)普貨(huo)，也就是非品牌貨(huo)物）。所以，如果寄(ji)(ji)(ji)重的而體積又(you)小(xiao)的東西(xi)，就用DHL、UPS等發貨(huo)。如果寄(ji)(ji)(ji)輕的而體積又(you)大(da)的東西(xi)，就用EMS發貨(huo)吧(ba)。
二、UPS與EMS有什么區別
寄國(guo)外(wai)快(kuai)(kuai)遞(di)可以用DHL、UPS、FEDEX、EMS和順(shun)豐等(deng)類(lei)的(de)國(guo)際快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)。在(zai)(zai)寄國(guo)外(wai)快(kuai)(kuai)遞(di)時(shi)，可以通過(guo)官網查詢對比(bi)再選擇合(he)(he)適的(de)快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)，找到合(he)(he)適的(de)快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)后，確認運費(fei)，達成運輸協議，再轉(zhuan)寄包(bao)裹到快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)，快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)再轉(zhuan)寄國(guo)外(wai)即可。上(shang)(shang)(shang)(shang)述講到的(de)國(guo)際快(kuai)(kuai)遞(di)公(gong)司(si)(si)(si)(si)的(de)優(you)勢(shi)(shi)如下：1、DHL，主(zhu)要優(you)勢(shi)(shi)在(zai)(zai)21KG以下的(de)小(xiao)貨(huo)(huo)上(shang)(shang)(shang)(shang)，時(shi)效(xiao)是比(bi)較穩定的(de)。2、UPS，主(zhu)要優(you)勢(shi)(shi)在(zai)(zai)100KG以上(shang)(shang)(shang)(shang)大貨(huo)(huo)上(shang)(shang)(shang)(shang)。大貨(huo)(huo)走(zou)UPS價格是比(bi)較好的(de)。3、FEDEX，主(zhu)要優(you)勢(shi)(shi)在(zai)(zai)21-99KG段，在(zai)(zai)這個重量(liang)段，FEDEX價格上(shang)(shang)(shang)(shang)是比(bi)較有優(you)勢(shi)(shi)的(de)，時(shi)效(xiao)也不(bu)會太差。4、EMS，擁(yong)有首屈一指的(de)航空和陸路(lu)運輸網絡，覆蓋最廣的(de)網絡體系為EMS實現(xian)國(guo)內300多個城市間次晨達、次日遞(di)提(ti)供了有力的(de)支撐。5、順(shun)豐，在(zai)(zai)服(fu)務方式上(shang)(shang)(shang)(shang)，順(shun)豐實行門(men)到門(men)、手(shou)到手(shou)交(jiao)接、送(song)貨(huo)(huo)上(shang)(shang)(shang)(shang)門(men)，并派(pai)專(zhuan)人上(shang)(shang)(shang)(shang)門(men)為客(ke)戶提(ti)供送(song)貨(huo)(huo)服(fu)務，對客(ke)戶送(song)的(de)商品沒有太多限制和要求。
三、國際快遞哪家公司最好
國(guo)(guo)際(ji)快遞(di)好的公司有(you)：UPS、FedEx、Panalpina、EMS國(guo)(guo)際(ji)快遞(di)、日本運通公司。

國際快遞注意(yi)事項(xiang)：
1、國(guo)際快(kuai)(kuai)遞包裹重(zhong)量(liang)分實際重(zhong)量(liang)和體積重(zhong)量(liang)兩種，快(kuai)(kuai)遞公(gong)司將(jiang)以兩種重(zhong)量(liang)中大的一項為計費依(yi)據；
2、體(ti)積(ji)重(zhong)計(ji)算：
（1）．四大國際快遞DHL、UPS、TNT、FedEX包(bao)裹體積重量的計算方(fang)法(fa)：（長 x 寬(kuan) x 高）（cm）
÷5000，注(zhu)意長(chang)寬高單位是(shi)厘米；
（2）．EMS郵(you)政速遞(di)，對長、寬、高(gao)三邊中任(ren)一單邊達(da)到(dao)60cm或以上的包裹進行計(ji)算體積重重量計(ji)算公式：體積重量（kg）＝長＊寬＊高(gao)（cm）÷8000；
3、國際快遞(di)包裹的貨物不(bu)足 0.5公斤的，按0.5公斤計(ji)費；
4、21Kg（46.3Ib）以下貨(huo)物(wu)按(an)照小(xiao)貨(huo)計(ji)費(fei)，按(an)首(shou)重、續重計(ji)費(fei)，計(ji)費(fei)單(dan)位為0.5Kg（1.1Ib）、21Kg及21Kg以上貨(huo)物(wu)按(an)大貨(huo)計(ji)費(fei)；
; 5、國際快遞包裹單件貨物(wu)的規(gui)(gui)格(ge)必須保證(zheng)：1長 + 2高 + 2寬(kuan) 330CM（各快遞公司要求的規(gui)(gui)格(ge)不盡(jin)相同）；
6、國(guo)際(ji)快遞包裹單件超過或等于(yu)68公(gong)(gong)斤／件的，必(bi)須用有(you)腳卡板進行(xing)包裝（部分國(guo)家拒收原本(ben)卡板包裝），否則快遞公(gong)(gong)司拒收貨物(wu)；
7、倘若有以下(xia)情(qing)況的國(guo)際快遞包裹(guo)，需預先訂艙：貨物(wu)單件維(wei)長超(chao)(chao)(chao)過330厘(li)米(mi)（10英(ying)尺25.2英(ying)寸）；貨物(wu)單件重量超(chao)(chao)(chao)過68公斤；貨物(wu)單件不超(chao)(chao)(chao)過330厘(li)米(mi)，重量不超(chao)(chao)(chao)過68公斤（149.9Ib），但(dan)一票貨超(chao)(chao)(chao)過300公斤（661.4Ib）。
