特朗普总统迈出了又一步，目的是通过呼吁扩大美国对联邦政府基础设施项目和其他购买的购买要求来帮助美国钢铁和其他行业。新利18备用网址

但是，特朗普对家庭挑战政策的期望改变将主要取决于对政府采购规则的尚未撰写的修正案。

此外，似乎特朗普的指令于7月15日签署，不会影响联邦援助公路工作（最大的联邦资助建筑计划），该计划受到不同优先要求的要求，称为购买America.

Brian Deery, senior director of the Associated General Contractors of America's highway and transportation division, sees the executive order as "sort of tightening down" on some provisions of federal procurement regulations.

Deery says, "It will clearly have an effect on direct federal programs," such as the Army Corps of Engineers, Naval Facilities Engineering Command and General Services Administration. Those agencies bid and award construction contracts directly to contractors.

But he adds that the directive "absolutely will not have a direct impact on the federal-aid highway program." That program provides highway funds to states, which are the entities that award contracts.

行政命令的主要部分将大大扩展对铁和钢最终产品的外国内容的定义，从而将阈值定为其总成本的5％。相比之下，目前的外国含量最低为50％。

特朗普在7月15日的白宫活动中说：“目前，一种产品可以是50％的外国，但仍然算作美国制造的产品。弄清楚那个。”

For non-steel and iron products, Trump initially is calling for a much smaller change, setting the new foreign-content level at 45%, compared with 50% now.

但美联储指令还要求eral officials to study a further cut in the non-steel foreign-content threshold, to 25%, with the change possibly coming “incrementally,” the document says.

此外，行政命令试图改变联邦机构的公式，以确定使用美国 - 原材料材料的公司合同价格是否“不合理或与公共利益不一致”。

为了提高美国材料的使用，该指令建议代理商在使用外国材料的竞争性竞标中向材料价格增加20％。对于使用外国材料的小型公司的出价，将增加30％的材料价格。

Those plus-factors are much higher than the present ones, which are either 6% or, in cases involving small bid amounts, 10%.

为了做出这些更改，行政命令将向联邦收购监管委员会求助，称其“应考虑”在180天内对联邦采购规则进行修订。

The rule-writing process can be lengthy. After a proposal is drafted, interested parties will have at least several weeks to submit formal comments. After those are reviewed, the council would write a final version.

该委员会由白宫联邦采购政策负责人以及国防部，GSA和国家航空航天局的官员组成。

美国钢铁学院欢迎行政命令。在一个陈述, Thomas J. Gibson, the institute’s president and chief executive officer, called the directive “another positive step in ensuring the fullest possible implementation and enforcement of existing domestic procurement laws and ensuring the steel industry remains competitive.”

Trump's new executive order follows two others he has issued that deal with Buy American policy. In January, he issued a指示that sought to widen the types of materials the Buy American preference would cover and also expand the program from those funded by federal grants to other types of "federal assistance."

That was a follow-on to an April2017年行政命令这主要着重于减少从购买美国购买要求的豁免权的使用。
