The 86-year-old act, which banned the import of good to the US produced by the involvement of slaves and child labor, is made stiffer and stronger by the new amendments implemented by US President Barack Obama.
Sen. Ron Wyden, an Oregon democrat who worked on the legislation said, "This law slams shut an unconscionable and archaic loophole that forced America to accept products made by children or slave labor", according to ABC News.
The tariff Act of 1930 enabled the Customs and border Protection Authority to take the necessary action against the shipments, which involved the slavery and child labor.
This act was totally used only 39 times and the last time was in the year 2000. Two words in the act created the big loophole.
"Consumptive demand" - which means the act, can be loosened and goods can be imported regardless of its make when the supply is insufficient to meet the needs of the domestic supply.
However, the President has now removed that loophole and deleted the two words, to make it stricter by signing the "The Trade Facilitation and Trade Enforcement Act" on Wednesday.
The explanations and doubts regarding the implementation of the new law are being planned by the US Customs and Border Protection Commissioner Gil Kerlikowske and agency leaders.
David Abramowitz, the vice president for Humanity United who voted for the change said, "If the U.S. government works to really keep out goods made with forced labor, this change will have a profound ripple effect on supply chains worldwide."
The human rights group has decided to use the Labor Department list of 350 goods, which are produced by slaves and children, to enforce the act. The list has the peanuts from Turkey, gold from Ghana, carpets from India and fish and shrimp from Thailand.
