As our usual practice, insurance covers basic risks only, at 110 percent of the invoice value. If coverage against other risks is required, such as breakage, leakage, TPND, hook and contamination damages, the extra premium involved would be for the buyer’s account. 按照我们的惯例,只保基本险,按发票金额110%投保。如果要加保其它险别,例如破碎险、渗漏险、盗窃遗失险、钩损和污染险等,额外保险费由买方负担。
