1.The hotmelt is made to order for ABC and setting up the line for 250kg packed in 100 foil bags was a reasonable production run.
To run 30 bags ~ 75kg will be more difficult to obtain. This will need to be discussed at length with the manufacturing Dept in Germany.

2.At this stage I cannot guarantee we could supply small quantities every three months.
It will be early January before I can talk to our UK Sales Manager and Germany are notoriously slow at coming back with firm offers.

1。我认为没问题.
结构是用and连接了两个完整句子。The hotmelt is made to order for ABC。我不会翻译，是不是：热熔粘合剂被生产出来，为了ABC（American Broadcast Company?）setting up the line for 250kg packed in 100 foil bags was a reasonable production run.建立一条（250kg分封于100个铝箔袋）的生产线是个合理的计划。
To run 30 bags ~ 75kg will be more difficult to obtain. This will need to be discussed at length with the manufacturing Dept in Germany.
75kg分装于30袋的计划很难实现。这得和德国制造署好好谈谈。

2.认为句子结构没错，个别用词实在看不懂。
现阶段，我不敢保证每3个月的小量供给。
明年1月份上旬我将和英国销售经理谈，而德国人在给予肯定回复方面是出了名的慢。
