Thousands of imported textiles and garments, auto parts and mechanical and electrical products were returned or destroyed in Shanghai port because of quality flaws.
The substandard products, which were seized in September, involved some international brands including H&M, Guess, Salvatore Ferragamo, M&S and GAP, according to the Shanghai Entry-Exit Inspection and Quarantine Bureau yesterday.
They failed for substandard color fastness, pH index and excessive formaldehyde, the bureau said.
Among the 39 substandard batches of imported products, 18 batches of H&M clothing or trousers made in Pakistan, Bangladesh, India, and Turkey failed for poor color fastness.
Dye in clothing with poor color fastness can bleed onto the skin, which can be harmful, officials said. The largest batch was 7,600 H&M boys' trousers made in Pakistan, according to the bureau.
A batch of 171 Guess jeans for boys that were imported from Tunisia failed for the same problem.
A batch of seven Salvatore Ferragamo shirts for men made in Italy failed for higher pH index than the standard.
Officials warned that textiles with high pH index can lead to skin allergies, particularly for children.
A batch of 1,600 GAP cold protective clothing for infants imported from Vietnam were found to have the same problem.
Four hundred M&S cotton knitted pajamas for girls imported from Sri Lanka failed for excessive formaldehyde.
Excessive exposure to formaldehyde can lead to headaches, dermatitis, respiratory disease and eczema, doctors said.
A batch of 314 Abercrombie & Fitch shirts for men imported from India also failed for excessive formaldehyde.
In addition, 92 Eagle automobile tires imported from the United States failed for lacking a China Compulsory Certification (3C) sign.
A batch of 80 Kogaz gas heating water heaters made in South Korea failed for electrical safety.
