Western Buyers Boycott Uzbekistan's Cotton

An Uzbekistan government official said the law prohibited children under age 16 from working. He added that even if children did work in the fields, it wasn't because they were forced to do so but because they wanted to. He declined to comment further.

Sportswear and equipment maker Adidas AG said it has signed a pledge, along with more than 50 of the world's best known apparel companies, not to knowingly source Uzbek cotton harvested using forced child labor.

"The Adidas group fully supports the pledge," said Frank Henke, the company's global director of social and environmental affairs. "We have been enforcing our code of conduct, the so-called 'workplace standards,' for many years, which includes a clear ban of child labor from our entire supply chain. By signing this pledge we are showing our unwavering commitment to the cause."

Swedish fashion giant Hennes & Mauritz AB, which also signed the pledge, said it also works to avoid buying from cotton producers that use children workers.

"The companies will maintain this pledge until the elimination of this practice is independently verified by the International Labor Organization," H&M press officer Charlotta Nemlin said. "H&M is a major cotton consumer and does not accept child labor."

Still, Keith Flury, senior commodity analyst at London-based Rabobank, warns that tracing the origin of cotton supplies remains a challenge for the industry.

"Traceability of fiber is easier than raw cotton, but given the complicated and globalized cotton supply chain it is difficult, and adds costs to account for origins in the final textile products," Mr. Flury said.

Uzbekistan harvested about 4.1 million tons of raw cotton last year and exported about 65% of that, according to the National Cotton Council of America.
