1. What GSP is
A unilateral scheme under which a developed importing country grants reduced or zero duty to products from developing countries.
It is not an agreement. It is granted, and it can be withdrawn or revised by the granting country.
2. The document
A non-preferential certificate of origin on the scheme’s prescribed form, or an origin declaration by an approved exporter where the scheme allows it.
3. The schemes worth knowing
The EU scheme
Graduated by product section. A country’s products can graduate out of a section as its competitiveness rises.
The UK scheme
Operates separately since Brexit, with its own country and product gradations.
Others
The United States, Japan, and several smaller economies operate their own schemes.
4. The instability
This is the defining feature and the reason exporters get caught.
Graduation
A country graduates out of a product section without any change on the exporter’s side.
Form revision
The certificate form is revised, and the old form stops being accepted.
Scheme replacement
Schemes are periodically rewritten.
5. A scenario
An exporter had used the GSP form for a product line for six years.
The destination graduated that section for China, and the goods moved to the MFN rate.
The exporter continued issuing GSP forms for three shipments after the change.
The certificates were refused, and the duty was charged at MFN with a delay.
6. What the exporter lost
Not just the preference. The time spent producing documents that had no effect.
7. What to check each year
Whether the product’s section is still eligible.
Whether the form is current.
Whether the scheme is still in force.
8. The record to keep
A row per destination and product section, with the eligibility status and the date last checked.
9. Closing view
GSP documentation looks like FTA documentation and behaves nothing like it.
The FTA is a contract. The GSP is a concession, and concessions are adjusted.
