由于国家对税收的调整，以致于我公司对贵公司印尼米黄的价格作出调整，特由我致电于您。
Because of the tax adjustment in our country, our company has to adjust the price of Indonesian Beige plates from your company. Hereby, I declare it to you.
想跟您商量一下贵公司印尼米黄荒料的价格。
I would like to discuss the price of Indonesian Beige materials of your company.
因为现在国内规定非金属产品出口不享受退税（包括大理石），这样的话我公司所做印尼米黄板材的成本又多出2.5美元。
Since there is no tax reimbursement to non-metallic products in China anymore, the cost of every Indonesian Beige plate made in our company has been increased by 2.5 dollars in this condition.
如果美国不加价，贵公司又不减价的话，今后我公司很难再做印尼米黄这个品种。
If America doesn't raise the price, and your company don't reduce the price, it is very hard for our company to produce plates of Indonesian Beige in the future.

现今美国方面同意加0.5美元。故我公司希望柜公司蒋荒料价格下调40美金，这样的话我公司蒋可以操作贵公司产品。望能尽快得到贵公司的答复。谢谢
Now that America agrees to increase 0.5 dollar, so we hope that you can reduce the price of materials by 40 dollars, so
