Tariff Rate Quota: In-Quota vs Over-Quota Rates and Bulletins

Key Points

• A tariff rate quota (TRQ) lets a set quantity enter at a lower in-quota rate and charges a higher over-quota rate on everything above it, but it never bars entry the way an absolute quota does.
• Quota priority is fixed when the entry summary is presented in proper form, which requires the merchandise to have arrived within the port limits and the estimated duties to be deposited.
• If a quota opens with more presented than the quantity allowed, the entries presented at the opening moment, 12:00 noon Eastern time on the opening date, are prorated.
• TRQs are administered either first-come first-served by CBP or through licenses, such as the USDA-licensed dairy quotas.
• If a shipment arrives after the quota fills, the options are to pay the over-quota rate, enter the goods into a warehouse, or hold them in a foreign-trade zone until the next period.

A tariff rate quota is a two-tier duty structure: goods entered within the quota quantity pay the lower in-quota rate, and goods entered above it pay the higher over-quota rate. Whether a line falls in the first or second tier depends on when the entry is presented in proper form, so timing, not just classification, drives the duty.

What a tariff rate quota is

TRQ versus absolute quota

The two quota types are easy to confuse. An absolute quota bars entry above the limit. A TRQ does not: it permits a quantity at the in-quota rate and charges the over-quota rate above it. Entry is always possible, and the cost changes.

The governing procedures sit in 19 CFR part 132, which covers quotas administered by CBP.

Two ways TRQs are administered

• First-come first-served: CBP counts entries against the quantity as they are presented, and the in-quota rate applies until the quantity is used up.
• License-based: The importer needs a license to claim the in-quota rate. The dairy quotas, administered through USDA licenses, are the standard example. Without a license, the over-quota rate applies.

Confirm which model applies to your product before you plan a shipment. A license-based TRQ cannot be fixed by timing the entry.

The opening moment and quota priority

What "presented in proper form" means

Quota priority and status are fixed by the time the entry summary is presented in proper form. Under 19 CFR 132.1, that requires two things:

• The merchandise has arrived within the port limits.
• The estimated duties have been deposited.

Goods still at sea, or an entry without the deposit, do not hold a place in line. Quota merchandise is filed as entry type 02.

Proration at the opening

The opening moment is 12:00 noon Eastern time on the opening date. If more is presented at that moment than the quota allows, the quantity is prorated among the entries presented at the opening moment. Everyone presenting at noon shares the in-quota quantity, and later entries do not get in-quota treatment once the quota is filled.

That is why brokers stage goods and deposits ahead of an opening. For examples of what recent openings looked like in practice, see CBP TRQ quota openings across beef, autos, food and apparel.

How to read a quota bulletin

CBP publishes quota bulletins and commodity status reports on its quota page. They are the working record of how much of each quota has been used. When you open one, check these elements:

• Commodity and HTS coverage: confirm your tariff line is covered by the quota, not just a similar product.
• Quota period: the dates the quantity covers, and the next opening if a period has ended.
• Quantity allowed and quantity used: how much in-quota volume remains.
• Status: whether the quota is open, filled, or not yet open, and whether proration applied at the opening.
• Administration: whether CBP counts entries or a license is required.

Treat a bulletin as a snapshot. A quota near its limit can fill between the time you read the report and the time your entry is presented. For a worked look at specific bulletins, see CBP quota bulletins for quartz surface products and the beef TRQ.

Chapter 99 headings that carry quota rates

Many quota rates are not in the base HTS line. They are reported through Chapter 99 headings in the Harmonized Tariff Schedule, alongside the Chapter 1 to 97 classification.

• Agricultural TRQs: the agricultural quota headings carry the in-quota and over-quota treatment for covered goods.
• Section 232 vehicle TRQ: heading 9903.94.31 applies to United Kingdom passenger vehicles and is the one live Section 232 TRQ.

Pick the heading that matches the quota tier you actually qualify for. Reporting an in-quota heading on goods that were not entered in-quota is a rate error that will surface later. For how other Section 232 vehicle headings are structured, see 9903.94.04: Section 232 passenger vehicle heading.

When a shipment arrives after the quota fills

A filled quota does not stop the shipment. The importer has three options:

1. Pay the over-quota rate. Enter the goods for consumption and accept the higher duty. This is the right call when the goods are needed now and the margin absorbs the cost.
2. Warehouse the goods. Enter them into a bonded warehouse and withdraw them when the next quota period opens.
3. Hold them in a foreign-trade zone. Keep the goods in the zone until the next period, then enter them to try for the in-quota rate.

Waiting is not free. Storage, carrying costs, and the risk that the next opening is itself oversubscribed and prorated all belong in the comparison with the over-quota duty.

What importers should do

• Confirm for each quota line whether it is first-come first-served or license-based, and secure any required license before the shipment is booked.
• Build the opening-day plan backward from 12:00 noon Eastern: goods inside the port limits, duty deposit funded, and entry type 02 ready to present in proper form.
• Check the current CBP bulletin and commodity status report before each entry, and decide in advance among over-quota payment, warehousing, or a foreign-trade zone if the quota fills.
• Verify the Chapter 99 heading on each line against the quota tier actually claimed.
