Federal authorities in New York on Wednesday seized a shipment of weaves and other beauty accessories suspected to be made out of human hair taken from people locked inside a Chinese internment camp.

This is the second time this year that CBP has slapped one of its rare detention orders on shipments of hair weaves from China, based on suspicions that people making them face human rights abuses.

Rushan Abbas, a Uighur American activist whose sister, a medical doctor, went missing in China almost two years ago and is believed to be locked in a detention camp, said women who use hair weaves should think about who might be making them.

In May, a similar detention was placed on Hetian Haolin Hair Accessories Co.

Ltd., although those weaves were synthetic, not human, the agency said.

The AP tried to visit Hetian Haolin Hair Accessories Co.

more than a year ago during an investigation into forced labor inside the camps.

From the road, it was clear the factory — topped with "Haolin Hair Accessories" in big red letters — was ringed with barbed wire fencing and surveillance cameras, and the entrance was blocked by helmeted police.

It was unclear whether the factory was part of a detention center, but former detainees in other parts of Xinjiang have described being shuttled to work in fenced, guarded compounds during the day and taken back to internment camps at night.

The Chinese Ministry of Affairs has said there is no forced labor, nor detention of ethnic minorities.

Representative Chris Smith said that while the allegations of forced labor are appalling, "sadly they are not surprising.".

"It is likely that many slave labor products continue to surreptitiously make it into our stores," said Smith, a New Jersey Republican who has taken a lead on anti-human trafficking legislation.
