We have no access to change product names in Dexco's SAP, and the product description is not required on the Commercial invoice, because the harmonized code is already listed. If Dexco wished to comply with the request to add Styrenic Block Copolymer, either the customers product code will need to be updated in SAP, or I would suggest putting it in the invoice header text field. If the customer's product name can not be updated, the only way I can think to update the COA is to just cut and paste Styrenic Block Copolymer on to the document.
