Magento默认无法导入Tier Price，需要在app/code/local/YOURMODULE/Catalog/Model/Convert/Adapter/Product.php 继续加入扩展方法。

已有的脚本里已实现过导入多图/多属性，自动创建目录，自动采集远程图片，现在再加导入Tier Price的功能。

核心函数：

private function _editTierPrices(&$product, $tier_prices_field = false)
{
if (($tier_prices_field) && !empty($tier_prices_field)) {
    if(trim($tier_prices_field) == 'REMOVE'){
        $product->setTierPrice(array());
    } else {
        $existing_tps = $product->getTierPrice();
        foreach($existing_tps as $key => $etp){
            $etp_lookup[$etp['price_qty']] = $key;
        }
        $incoming_tierps = explode('|',$tier_prices_field);
        foreach($incoming_tierps as $tier_str){
            $tmp = explode('=',$tier_str);
            $tps_toAdd[$tmp[0]] = array(
                                'website_id' => 0, // !!!! this is hard-coded for now
                                'cust_group' => 32000, // !!! so is this
                                'price_qty' => $tmp[0],
                                'price' => $tmp[1],
                                'delete' => ''
                            );
            if(isset($etp_lookup[$tmp[0]])){
                unset($existing_tps[$etp_lookup['price_qty']]);
            }
        }
        $tps_toAdd =  array_merge($existing_tps, $tps_toAdd);
        $product->setTierPrice($tps_toAdd);
    }
}
}

然后在saveRow函数里找地方加入：

if(
    isset($importData['tier_prices'])
    && !empty($importData['tier_prices'])
){
    $this->_editTierPrices($product, $importData['tier_prices']);
}

CSV文件里要有字段”tier_prices“，值的格式例子：qty=price|qty=price|qty=price

比如：50=12.25|500=11.70|5000=11.00

这样Magento就能导入Tier Price了
