API Spec 5CT Marking

I am in trouble with API marking

The new issue, how can I show the pipe length in marking?

Should I measure each pipe and add the result at the end of marking as meter, or
just adding "Range 1" at the end of marking is enough?

Marking / length normally mentioned by the Mill at the time of mill roll. However it all depends upon customer. Some people OK with Range 1, Range 2 or Range 3 description or some need exact length of tally of these joints. Like our customer issue purchase order on inch basis and we have to measure each and every pipe according to inches. Following is as per API5CT requirement
