Short answer
- A tariff is a tax on imported goods (a price per unit or percentage of value). It raises the domestic price and generates government revenue.
- A quota is a quantitative limit on the amount of a good that may be imported over a period. It restricts quantity rather than directly changing price, and typically creates scarcity rents.

Key differences (concise)
- Type: tariff = tax (price instrument); quota = quantity limit (quantity instrument).
- Effect on imports: tariff reduces imports by making them more expensive; quota fixes the maximum import volume.
- Price outcome: tariff raises the domestic price by roughly the tariff amount; quota raises the domestic price to the level at which domestic supply + allowed imports meet demand.
- Revenue: tariff revenue goes to the government; quota rents (the difference between domestic and world price times import quantity) go to whoever holds the import licenses — which could be foreign exporters, domestic firms, or auction winners.
- Predictability/control: tariff gives predictable per-unit cost but uncertain import volume; quota gives precise control of import volume but uncertain domestic price.
- Administration: tariffs are easier to administer and less distortionary; quotas require allocation rules (licenses, auctions, first-come) and encourage rent-seeking and smuggling.
- WTO/trade law: tariffs are generally more acceptable under WTO rules; many quotas are prohibited or constrained (except under specific agreements like tariff-rate quotas).

Illustrative example
- World price of widgets = $10. A $4 tariff makes imported widgets cost $14 to domestic buyers; imports will fall but the government collects $4 per imported widget.
- A quota limiting imports to 100 widgets will raise domestic price until domestic supply + 100 imported widgets equals demand; the price could be higher than $14, and the extra margin (price minus $10) times 100 becomes quota rent for license holders.

When policymakers use each
- Tariffs: used when the government wants revenue and protection and prefers transparent, administrable tools.
- Quotas: used when a government’s priority is to limit quantity strictly (e.g., protect an infant industry or address sudden surges), though they are distortionary and politically contentious.

Related variant
- Tariff-rate quota (TRQ): a hybrid — a low (or zero) tariff up to a quota amount, and a higher tariff on additional imports.

If you want, I can show a simple supply-demand diagram or a numeric welfare analysis (consumer surplus, producer surplus, government revenue, deadweight loss) for each.
