The arrangement is an interim, limited-scope deal, not a full free trade agreement. It was negotiated ahead of the comprehensive agreement, and it liberalises a named list of products rather than the whole tariff book. That list is where the value sits: goods outside it are assessed at the ordinary rate whether or not you hold a certificate, so the first question is always whether your HS line is in the schedule at all.
The operating rules come from the Measures on the Administration of Origin of Import and Export Goods under the Early Harvest Arrangement between China and Honduras, issued as GACC Announcement No. 111 of 2024 (published August 19, 2024, effective September 1, 2024). Annex 1 of the announcement is the certificate format itself. Read the 2024 measures as the rulebook; earlier commentary on China–Central America trade does not apply to it.
In China's import declaration system, agreement code 27 identifies this arrangement, and the certificate carries type code HD — which is why the trade simply calls it Form HD. Code 27 belongs on an entry filed into China for goods of Honduran origin; it is not a field your Honduran broker keys in, and it should not appear on a commercial invoice as if Honduras required it.
The certificate is filled in English, carries a unique number, covers one consignment, states the basis on which origin is claimed, and has to be free of alterations and overprinting — the seal and signature must match the specimen the importing side holds. One certificate, one shipment, one entry.
Origin, the hard part. There are two qualifying routes. Wholly obtained or produced in China: grown, harvested, mined, caught, bred or manufactured there with no imported inputs. Or produced exclusively from originating materials — every input is itself Chinese or Honduran origin under the arrangement. Bilateral cumulation applies: Honduran originating materials used in production in China are treated as originating, and the reverse holds as well.
Everything else is excluded by design. There is no regional value content formula to fall back on, no tariff classification change rule, and no tolerance for a small share of non-originating material. The only listed carve-outs are supporting items that do not enter the product: fuel and energy, catalysts and solvents, plant and equipment, gloves, glasses and footwear, tools, dies and moulds, spare parts, and lubricants. Transport packaging and retail packaging are handled separately and do not affect origin either.
Where most applications fail: a product assembled in China from imported modules is not wholly obtained, and it is not made exclusively from originating materials. Under a value-test agreement the same goods might clear at 40% regional content; under this arrangement there is no test to clear. Filing anyway means a false origin declaration, which lands on the exporter and later on your entry.
