Using harmonized code in Product Import CSV file?

[wikkidchik]

Every two weeks I update many products using the Product Export/Import CSV file because I update variants and variant images. But because I ship to Canada, I need to be able to add Harmonized Codes to these new variants. The Product Export/Import CSV file does not contain fields to add this information to each variant.

I see that the Product Inventory CSV contains these fields, but I don't want to do multiple uploads for the same products that tweak different bits of information.

My question is, can I just add the HS Code field and COO (country of origin) fields to the Product Export/Import CSV file so that these two bits of information get updated with the main Product Import file?

TIA!

Shamless plug, but you can use Mellow's spreadsheet software to do so (supported barcodes: GTIN, ISBN, UPC, EAN, MPN):
