Shipping & Logistics Terms

Beyond the basics, there is a whole vocabulary around shipping. "Rehearsal packing" means the agent pre-packs to give you exact weight. "Volumetric weight" is the dimensional calculation carriers use for bulky items. "Declared value" is the amount you tell customs the package is worth, which affects duties.

Mastering this vocabulary takes you from confused beginner to confident buyer in days. When you understand what GL and RL mean, you can participate in QC threads and learn from the community at 10x the speed of someone guessing.

Frequently Asked Questions

GP stands for Guinea Pig — being the first person to order from a new seller or batch. It carries risk because there are no reviews yet, but it also means you get to discover new sources before the crowd. Only GP with small test orders under $50.
