外贸付款方式D⼀P 还是D⼀A

D/A：documents against acceptance：承兑交单。
D/P：documents against payment：付款交单。
On Collection: After shipment, the Sellers may draw on the Buyers at sight and send the draft(s) together with the shipping documents specified in Clause 10(1) hereof, to the Buyers through the Sellers' bankers and the Buyers’ Bank for collection.
托收：装运后，卖方开到买方即期汇票，并连同装运单据一并交付买方（进口国托收行）；以上按照条款10（1）通过卖方银行和买方银行进行托收。
付款交单：
1）.draft at sight：即期汇票----D/P：即期付款交单。
2）draft after sight：远期汇票----D/P after sight：远期付款交单。
3）D/P after sight：远期付款交单：出口商开出远期汇票（随装运单据一并寄往进口国托收行）----进口商审核无误承兑----托收行（进口国）代为保管（远期汇票和装运单据）----进口商付款托收行，取得装运单据（汇票到期日前）。
因为看到你这里是at sight而如果是承兑交单或者远期付款交单会出现draft after sight or after *** days。所以，我觉得是D/P at sight。
