Garment exporters could still lose orders even though US Customs has lifted entry bond measures introduced to eradicate alleged transshipment irregularities in the territory.
At the opening of a textile trade fair, Hong Kong Exporters' Association chairman Willy Lin said the bond issue still needed clarification.
US Customs last week said it would scrap entry bonds imposed on eight categories of garments exported from Hong Kong.
It also dropped a watch list on which four other categories of Hong Kong exports were awaiting possible bond requirements.
The decision was made after officials concluded their second round of factory visits in the territory in February.
Mr Lin said garment makers were still under threat because the US could increase a standard bond on all imports.
