交货 is a separable verb (离合词) meaning 'to deliver goods', commonly used in business and logistics contexts. The verb 交 ('to hand over') and the object 货 ('goods') can be split when you add aspect markers (了, 过), measure words, or time expressions in between (e.g. 交了货 'delivered the goods', 交过一次货 'delivered once'). Do not place a direct object after 交货; instead, use 给 + recipient to specify whom you deliver to.
