How to Import With Restrictions and Quotas
Import restrictions and quotas can cap how much of a product may enter, add a steep duty, or bar it from entry entirely — and they turn on the exact product and country of origin, not the broad category. A shipment that looks routine can be stopped by an antidumping order, a tariff-rate quota that has already filled, or a forced-labor presumption. This guide explains the main types of restriction, who administers each, and how to check before you commit to an order.
Restrictions Attach to the Product and the Country
Every restriction screen starts with two facts: your precise HTSUS classification and your country of origin. The same product can be unrestricted from one country and subject to a quota or antidumping order from another. So before you order, pin down the tariff classification and confirm origin under CBP’s rules — the rest of the analysis flows from those two answers. The restriction layer sits on top of the normal import process; it does not replace your entry, valuation, or recordkeeping duties.
The Main Types of Restriction
| Restriction | What it does | Who administers it |
|---|---|---|
| Absolute quota | Caps the quantity that may enter in a period; excess is held or re-exported | CBP |
| Tariff-rate quota (TRQ) | Lets a set quantity enter at a low rate; imports above it pay a higher rate | CBP |
| Antidumping / countervailing duty | Adds duties to offset unfair pricing or foreign subsidies | Commerce + ITC; CBP collects |
| Forced-labor ban | Bars goods made with forced labor from entry | CBP, under 19 U.S.C. § 1307 |
| Import licenses / permits | Require agency authorization for specific goods | FDA, ATF, USDA, and others |
Quotas: Absolute vs. Tariff-Rate
An absolute quota sets a hard ceiling: once the quantity for the period is reached, no more of that product can enter until the quota reopens. A tariff-rate quota (TRQ) is softer — a defined quantity enters at a preferential duty rate, and anything beyond it still enters but at a higher rate. CBP administers both, generally on a first-come, first-served basis by presentation time, which is why timing your entry can matter when a quota is close to filling.
Antidumping and Countervailing Duties (AD/CVD)
AD/CVD orders are the restriction most likely to surprise an importer, because they can add duties far larger than the base tariff. The process runs across two agencies: the Department of Commerce determines the dumping margin or subsidy rate, and the International Trade Commission determines whether a U.S. industry was injured. If both are affirmative, Commerce issues an order and instructs CBP to collect cash deposits at the margin rate on each entry. Rates are product- and producer-specific and change through annual reviews, so always check the current order for your exact goods and supplier rather than relying on a past rate.
Forced-Labor Bans
Under 19 U.S.C. § 1307, goods made wholly or in part with forced labor are barred from entry. CBP enforces this through Withhold Release Orders and, for goods tied to China’s Xinjiang region, the UFLPA’s rebuttable presumption (covered in our textiles guide). Overcoming a detention requires clear and convincing supply-chain evidence, so this is a due-diligence problem you solve before importing.
How to Screen Before You Buy
Run this check during sourcing, not after the goods ship:
- Classify the product and confirm the country of origin under CBP rules.
- Search the active AD/CVD orders for that product and country; budget for cash deposits if an order applies.
- Check the current quota status if your product falls under an absolute quota or TRQ.
- Screen for forced-labor risk, especially for cotton, polysilicon, and other high-risk inputs.
- Confirm any license or permit the regulating agency requires.
Build the cost of any duties and the risk of any cap into your pricing before you place the order. A missed AD/CVD order can erase a margin overnight.
Frequently Asked Questions
What is the difference between an absolute quota and a tariff-rate quota?
An absolute quota caps the quantity that can enter — excess is held or re-exported. A tariff-rate quota lets a set quantity enter at a lower duty rate and charges a higher rate on anything above it, so over-quota goods can still enter, just at greater cost.
Who decides antidumping and countervailing duties?
The Department of Commerce calculates the dumping or subsidy margin and the International Trade Commission decides whether a U.S. industry was injured. If both findings are affirmative, Commerce issues an order and CBP collects cash deposits on affected entries.
How do I know if my product faces a restriction?
Start from your exact HTSUS code and country of origin, then check active AD/CVD orders, current quota status, forced-labor risk, and any agency license requirement. Because restrictions are product- and country-specific, a general category check is not enough.
Can restricted goods still be imported?
It depends on the restriction. TRQ goods can enter above the quota at a higher rate; AD/CVD goods can enter with cash deposits; but absolute-quota goods are blocked once the cap is hit, and forced-labor goods are barred entirely unless the presumption is rebutted.
The restrictions that hurt importers most are the ones discovered after the order is placed.
