Please correct my grammar, thanks

We have arranged for the surveyor to inspect these goods in November (or do you mean, on 7th November).
After that: your paragraph sounds like it is part of a formal letter to a client or customer, so that "after that" is slightly too informal. You could say, "Following this inspection, they will submit a certificate to us which will certify that these goods can be returned to China. This certificate will be sent/forwarded ("forwarded" is more in keeping with the formal tone of the letter) to you as soon as possible. The charge for this is USD240, which we will deduct (which will be deducted) from your next payment.
(By using the passive tense -will be deducted - you are making it more formal, which is more in keeping with a business letter, less personal, as it avoids using the personal pronoun "we".)

Please advise when you will be able to collect the goods ("pick up" is too informal, too casual for a business letter)
for return to your factory for ...
reworking: I am unsure whether this is the best word, as I don't know what the actual goods are, or what is apparently wrong with them. Possible alternatives are,
for modification, for repair, for alteration.
Hope this helps.
