Mike,
"Drying" for solvent finishes (Lacquer & Shellac) is evaporation, not "off gassing".
Reactive finishes like oil finishes first "dry" as the carrier solvents evaporate, but then do create very small amounts vapor as part of the polymerizing chemical process. That can take up to several weeks. VOC ratings focus on the solvents (alcohols, stoddard/naptha, acetones, etc) used to create the finish liquids. Once those solvents evaporate (few days to a week), the finish film is essentially VOC free as stated by your finisher. The point here is that as long as whatever you use is "dry" and/or "cured" when you deliver the items to your customer, they will be essentially VOC free.
