GSP Renewal 2026: Status of HR 4276 and the Retroactive Refund Picture
The US Generalized System of Preferences (GSP) expired December 31 2020 and has not been reauthorized. Multiple renewal bills have moved through Congress without final passage. If a retroactive renewal eventually passes, importers can claim refunds of duties paid on GSP-eligible imports back to January 1 2021.

The US Generalized System of Preferences (GSP) expired December 31 2020. Five years later, despite multiple renewal bills clearing committees in successive Congresses, the program has not been reauthorized. The 119th Congress is now working on HR 4276 with committee approval but no floor passage as of mid-2026. For US importers buying from the 119 beneficiary developing countries, the cumulative refund opportunity is now approximately 4.5 to 5 billion USD.
This guide covers the current status of GSP renewal, the HR 4276 bill text, the retroactive refund mechanics, and what importers should do today to preserve their refund position.
What GSP did
The US Generalized System of Preferences, enacted in the Trade Act of 1974, provided duty-free treatment for eligible products from designated beneficiary developing countries. The program covered approximately 5,000 8-digit HTS subheadings and 119 countries when it expired.
For eligible products from eligible countries, the importer claimed GSP at entry via the Special Program Indicator (SPI) code A or A+ on the entry summary. CBP applied the GSP rate (zero) instead of the standard MFN duty.
Major beneficiary countries: India (until 2019 when graduated), Indonesia, Turkey, Thailand, Brazil (graduated 2018), Vietnam, Philippines, South Africa, and ~110 smaller economies.
Why GSP expired
Congressional reauthorization is required periodically. The 2020 expiration coincided with a broader trade policy reshape that has produced gridlock on related preference programs (AGOA, CBI, Andean Trade Preference) too. Procedural and substantive disputes include:
- Country eligibility (specifically whether to graduate countries that have grown beyond developing-country status).
- Worker rights conditions.
- IP enforcement conditions.
- Petitions to remove specific countries (Turkey was removed before expiration).
- Linkage to broader trade negotiations.
The renewal language in each successive bill has been substantively similar, but the bills have stalled at floor consideration.
HR 4276 status
HR 4276 (Generalized System of Preferences Reauthorization Act of the 119th Congress) was introduced in 2025 and cleared the House Ways and Means Committee in late 2025. The bill provides:
- Reauthorization through December 31 2030 (5-year window).
- Retroactive refund of duties paid on GSP-eligible entries between January 1 2021 and the date of enactment.
- Updated country list reflecting graduations and additions since 2020.
- Modified eligibility conditions on worker rights and IP enforcement.
- Specific carve-outs and modifications for individual countries.
As of June 2026, the bill awaits floor consideration in the House and Senate. The retroactive provision is intact in the committee-passed version.
Worked example: retroactive refund exposure
A US importer brought in 100,000 USD per quarter of HTS 6109.10 cotton T-shirts from Bangladesh (a continuing GSP beneficiary) from 2021 to 2026. Without GSP, the MFN was 16.5 percent. With GSP, the duty would have been 0 percent (assuming Bangladesh-origin and substantial transformation met).
| Year | Quarterly volume | Annual GSP duty paid |
|---|---|---|
| 2021 | 100,000 | 66,000 |
| 2022 | 100,000 | 66,000 |
| 2023 | 100,000 | 66,000 |
| 2024 | 100,000 | 66,000 |
| 2025 | 100,000 | 66,000 |
| 2026 (half year) | 100,000 | 33,000 |
| Cumulative refundable | 363,000 |
If HR 4276 passes with retroactive language intact, this importer recovers 363,000 USD plus interest. The interest accrual at CBP's published rate (around 7 percent annualized in 2026) adds another 50,000 to 80,000 USD depending on entry dates.
For the 119 beneficiary countries combined, the program-wide refund pool is approximately 4.5 to 5 billion USD across all importers.
How retroactive refunds would work
The historical pattern from prior GSP renewals (2010, 2015, 2018) is that CBP processes refunds in two channels:
Channel 1: Automatic refund for entries with GSP claim flag. Importers who continued to file the SPI code A or A+ on entries during the expiration window are automatically processed. CBP runs an automated refund batch against the entry database, applies the GSP rate retroactively, and refunds the difference plus interest. Typical processing time after renewal passage: 3 to 9 months.
Channel 2: Protest filing for entries without GSP flag. Importers who stopped filing the flag (or never filed) must file individual protests under 19 USC 1514 for each affected entry. The protest cites the renewal statute, identifies the GSP-eligible entry, and requests the refund. Typical processing: 12 to 24 months per protest.
Channel 1 is dramatically faster and cheaper. The CBP guidance throughout the 2021 to 2026 expiration has been to keep filing the GSP flag to preserve Channel 1 eligibility.
What importers should do today
1. Continue filing GSP claim codes on every eligible entry. Even though no refund is being processed today, the flag preserves Channel 1 eligibility for when renewal passes. Cost: zero (just data field on the entry summary). Benefit: orders of magnitude faster refund processing.
2. Document the GSP eligibility of each entry. Maintain origin documentation, substantial transformation evidence, and country-eligibility records as if GSP were in force. CBP will audit refunded entries.
3. Calculate your exposure. Build a spreadsheet of all GSP-eligible imports since January 1 2021 with the MFN duty paid. This is the refundable amount when renewal passes.
4. Engage trade counsel for high-value refund cases. If your cumulative exposure exceeds 500,000 USD, the legal preparation for protest filing (if Channel 1 fails) is worth the cost.
5. Track the renewal bill. HR 4276 in the 119th Congress is the active vehicle. Subscribe to USTR and Ways and Means committee updates. The bill could pass quickly if attached to a must-pass vehicle (NDAA, appropriations, infrastructure package).
EU GSP context
The EU operates a separate GSP for 2026-2028 cycle. Notable change: India was largely graduated out of EU GSP+ in January 2024 based on per-capita GNI thresholds. EU GSP coverage continues for ~60 lower-income countries on a separate schedule.
EU-bound imports from countries still in the EU GSP get preferential rates. India-EU trade now pays full EU MFN.

Frequently asked questions
Is GSP currently in force?
No. The US Generalized System of Preferences expired December 31 2020 and has not been reauthorized as of June 2026. All previously GSP-eligible imports pay full MFN duty since January 1 2021. CBP continues to accept GSP claim codes (the A or A+ Special Program Indicator) on entry summaries so that retroactive refunds can be processed if renewal passes.
How big is the retroactive exposure?
GSP coverage was approximately 5,000 HTS subheadings across 119 beneficiary developing countries. Annual duty assessed on GSP-eligible imports under the post-expiration regime has been roughly 800 million USD per year. Cumulative duty paid 2021 to 2026 is approximately 4.5 to 5 billion USD that would be refundable on retroactive renewal.
What is HR 4276?
HR 4276 (Generalized System of Preferences Reauthorization Act) is one of several GSP renewal bills introduced across the 117th, 118th, and 119th Congresses. The 119th Congress version has cleared committee but not passed both chambers as of mid-2026. The retroactive provision has been included in all versions.
Should I still file GSP claim codes on entries?
Yes. CBP's standing guidance is that importers should continue to flag GSP-eligible entries with the appropriate SPI code so that retroactive refunds can be processed automatically (or via protest) once renewal passes. Without the flag, the importer must file individual protests for each entry, which is significantly more costly.
What about the EU GSP and other countries' GSP programs?
The EU GSP runs on a separate 2026-2028 cycle that excluded India for most products as of January 2024 due to GNI graduation. Australia, Canada, Japan, Norway, Switzerland, UK each operate their own GSP programs. The US GSP is the largest single program in dollar terms and the most consequential when reauthorized.
