急！非原木包装Consignment identifier这一句是什么意思啊

我的澳大利亚一客户需要如下文件证明我们的包装是非原木包装，请问Consignment identifier(s) or Numerical Link(s):______这一栏是什么意思？该填什么呢？ Ps:我们产品的包装是三合板，不在熏蒸范围内，只要个以下的证明就可以，但是我实在是不清楚那个序列号是什么意思，麻烦知道的大侠讲下吧，小女子感谢不尽啊~~ 请各位高人不吝赐教，感激不尽，谢谢谢谢！ 首先先解释下这个公约的源起吧，ISPM是国际植物保护公约（International Plant Protection Convention，简称IPPC）秘书处所发布的国际植物检疫措施标准第15号出版物《国际贸易中木质包装材料管理准则》（Guidelines for　Regulating Wood Packing Material in International Trade），即为国际木质包装植物检疫措施标准，简称第15号国际植物检疫措施标准（ISPM15）。 FCL ISPM 15 Packing Declaration [Boxes □ to be marked with an X in the appropriate place.] Ship Name:_________________________ Voyage Number:_________________________ Consignment identifier(s) or Numerical Link(s):____________________________________ Straw packing includes straw,cereal,rice hulls,and other unprocessed plant materials.)
