Before you finalize the order, do a quick mental checklist:

• COA received and verified against the product.
• Label matches the COA for strength and type.
• Batch number visible on each unit.
• Your market actually wants this strength—don't order 50 mg if your customers usually buy 20 mg.
• Storage plan is ready—cool, dry, and away from sunlight.

Nicotine strength is a compliance issue as much as a sales issue. Get it right, and you'll have fewer returns and more repeat customers. Get it wrong, and you'll be dealing with complaints and chargebacks. The ten minutes you spend verifying will save you hours later.
