Product dimensions (length, width, height) are not imported with node_import

I use node import for importing products into my website. And I noticed that dimensions get lost during this process.

When I reach Preview import (step 7 of 8) I see no information about dimensions.

I tried a module http://drupal.org/node/685698#comment-4024112 and it did not help.

I wanted to use a patch http://drupal.org/node/685698#comment-3366822 but I saw that it is already included to UC 2.9 uc_product.module version.

What else can I do to process dimensions during the import?
