339.We have now decided to supply you with all the parts as itemized in your order and going
to apply to the government agencies concern for export licenses.

itemized作为开列，修饰什么

all the parts as itemized in your order
是不是订单里开列的所有部件
we wish to order from you your products as per our purchase
as per 修饰什么 什么意思

我来回答，希望您满意：

339.We have now decided to supply you with all the parts as itemized in your order and going to apply to the government agencies concern for export licenses.
339. 我们现决定向贵处提供订单中开列的所有零部件，并向相关政府机构申请出口许可证。

all the parts as itemized in your order
订单中开列的所有零部件

We wish to order from you your products as per our purchase
我们希望能采购贵处产品。

as per 根据（这里是“根据我方的采购计划”或“根据采购单”的意思，直接用as per purchase）

例句：

As per the contract, the construction of factory is now under way.
根据合同规定，工厂的建设正在进行中。

For the cost of the articles, I have debited you￡51.70, as per note annexed.
如附件说明，货价51.70英镑，已记入贵方借方帐项。

Kindly forward these by fast freight. enclosed please find a draft as per memorandum bill you send us.
上述货物，请尽快发货。按照贵公司寄我司的价格单，同函寄上汇票一份，请查收。

itemized作为开列，修饰all the parts,表示列的是这些部件 all the parts as itemized in your order 是订单里开列的所有部件 we wish to order from you your products as per our purchase as per ：按照，是动词/副词，表示按照我们的购买（单）。

作定语修饰all the parts 。 再看看别人怎么说的。

被列出的，当然是过去时态表被动了，like "broken shoes"

修饰他的order阿，itemize 表示列清单阿
