The Generalized System of Preferences (GSP) is a US trade programme that grants duty-free access for thousands of products from designated developing-country beneficiaries. Authorised under the Trade Act of 1974 and administered by the Office of the United States Trade Representative (USTR) and US Customs and Border Protection (CBP), GSP is the principal US tariff-preference programme for non-FTA developing-country trade. The programme covers approximately 119 beneficiary countries (the list changes annually) and approximately 5,000 products defined by HTS code.
How GSP works
A US importer claims GSP by entering the cargo under the relevant HTS code with the special program indicator “A” (or “A+” for least-developed-country beneficiaries) on the customs entry. Three conditions must be met:
- The exporting country is a current GSP beneficiary. Beneficiary status is reviewed annually; countries can be added or removed by USTR.
- The product is GSP-eligible. Most HTS codes covering manufactured chemicals, raw materials, and consumer goods are eligible. Some products (textiles, footwear, certain agricultural goods, certain steel products) are excluded.
- The product satisfies rules of origin. Generally, the product must have at least 35% local content (the value added in the beneficiary country plus the cost of materials produced there) and must undergo “substantial transformation” in the beneficiary country.
When the conditions are met, the import is duty-free. Without GSP, the import pays the standard MFN tariff rate.
Why GSP does not apply to Chinese imports
China was never a GSP beneficiary. The programme is reserved for developing countries that meet specific eligibility criteria, and China was excluded from the original 1976 list and has remained excluded ever since. Chinese chemical exports to the US pay the standard MFN tariff plus any applicable Section 301 surtax plus any AD/CVD duty. There is no GSP path for Chinese cargo.
Why Chinese sourcing decisions still need to consider GSP
Three patterns in chemical sourcing make GSP relevant even when buying from China:
- Alternative-source diligence. A buyer evaluating whether to move sourcing from China to Vietnam or Thailand needs to know whether the destination country is a current GSP beneficiary. If yes, the GSP duty preference offsets some of China’s price advantage. Vietnam and Thailand are both GSP beneficiaries; India returned to the programme in 2024 after a 2019-2024 suspension.
- Substantial transformation as a relabelling pathway. A Chinese-origin chemical that is further processed in Vietnam or Thailand to a degree that meets substantial transformation can claim GSP origin under the new country. This is the “third country processing” pathway, and it is heavily scrutinised by CBP under the UFLPA and forced-labor-due-diligence framework. It is not a routine workaround.
- GSP-renewable status. GSP authorisation lapses periodically when Congress fails to renew it. The programme lapsed from 2021 to early 2025, during which all GSP claims paid the MFN rate; refunds were issued retroactively after Congress passed the renewal. Importers planning around GSP need to track the authorisation status.
Beneficiary country list (2026)
Active GSP beneficiaries include:
- Asian beneficiaries: India, Indonesia, Pakistan, Sri Lanka, Cambodia, Bhutan, Bangladesh, Maldives, Nepal, Mongolia, Laos, Yemen, Vanuatu
- Latin American beneficiaries: Argentina, Brazil, Bolivia, Ecuador, Paraguay, Uruguay, several CARICOM nations
- African beneficiaries: Most sub-Saharan African nations
- Pacific beneficiaries: Various Pacific Island nations
Notably absent: China, South Korea (graduated in 1989), Taiwan (graduated in 1989), Hong Kong (graduated in 1989), Singapore (graduated in 1989), and Russia (suspended).
China and the four “Asian Tigers” graduated as their economies matured. The graduation criteria are based on per-capita income relative to the US.
Common GSP-eligible chemical HTS codes
Many HS Chapter 28 (inorganic chemicals) and Chapter 29 (organic chemicals) codes are GSP-eligible. A few examples for chemical buyers comparing Vietnam vs China sourcing:
| HTS code | Product | MFN tariff | GSP eligible? |
|---|---|---|---|
| 2904.99.20 | Aromatic sulphonates | 6.0% | Yes |
| 2917.19.30 | Sebacic acid | 4.5% | Yes |
| 2918.14.00 | Citric acid | 6.0% | Yes |
| 2924.29.71 | Other amides | 6.5% | Yes |
| 2933.39.10 | Pyridine and its salts | 6.0% | Yes |
For these products, a Vietnam or Thai supplier offers up to 6.5% duty saving over a Chinese supplier of the same product (before factoring Section 301 and AD/CVD on the Chinese side).
How GSP catches importers off guard
Three failure patterns recur:
- Authorisation lapse. GSP authorisation has lapsed multiple times pending Congressional renewal. Importers who book based on duty-free GSP rates may suddenly face MFN rates if the renewal is delayed.
- Country graduation. A country can be removed from GSP through graduation (per-capita income threshold), competitive-need limit (CNL), or specific bilateral disputes. India was removed in 2019, restored in 2024; Turkey was removed in 2019.
- Product graduation under CNL. Even within an active beneficiary country, specific products can be excluded from GSP if their export volume to the US exceeds the competitive-need limit. The CNL list updates annually.
How GSP interacts with Section 301 and AD/CVD
GSP applies to imports from beneficiary countries. Section 301 applies to imports from China (and a few other targeted countries). AD/CVD applies to specific products from specific countries. These regimes do not overlap on the same shipment:
- Vietnam-origin product → GSP eligible (if beneficiary status holds), no Section 301, may have AD/CVD if Vietnam-specific orders exist
- China-origin product → GSP not eligible, Section 301 stack applies, AD/CVD may apply on top
- Vietnam-origin product with Chinese inputs that have been substantially transformed → claims Vietnam origin → GSP eligible (subject to UFLPA scrutiny)
For Chinese chemical imports specifically, the practical consequence is that the GSP duty saving is not available; the buyer’s only duty-mitigation pathway in the US is duty drawback (refund on re-export) or bonded warehouse deferral.

Section 301 is the China-specific tariff regime. Anti-Dumping Duty and Countervailing Duty are the trade-remedy duties. Free Trade Agreement Tariff is the parallel preference path through bilateral FTAs. Rules of Origin determines whether a product qualifies for GSP. HTS Code classification determines GSP eligibility per product. ChAFTA is the China-Australia FTA, a parallel preference framework on the Australia side.
