HS Code 3702.97 – Photographic film; other than for colour photography, in rolls, sensitised, unexposed, of a width not exceeding 35mm and of a length exceeding 30m (other than paper, paperboard or textiles)

HS code 3702.97 is the 6-digit subheading for photographic film, other than for colour photography, in rolls, sensitised, unexposed, of a width not exceeding 35mm and of a length exceeding 30m (other than paper, paperboard or textiles). It is used for bulk 35mm black and white negative film (100ft rolls), bulk 35mm black and white reversal film (50m rolls), motion picture black and white film stock (short ends), microfilm (35mm width) and archival black and white film (bulk).

What HS 3702.97 covers

This HS code pertains to unexposed black and white photographic film in rolls, characterized by a width not exceeding 35mm and a length exceeding 30 meters. This bulk format is primarily utilized by professional darkrooms, film schools, motion picture production houses for specialized effects, and scientific or industrial applications requiring extensive lengths of monochrome film. The trade is driven by a niche but consistent demand from institutions and professionals who value the specific characteristics of black and white film for artistic, archival, or technical purposes. Exporters are typically countries with a strong legacy in photographic chemical manufacturing, while importers include nations with active film preservation efforts, educational programs, or specialized imaging industries. Precise adherence to the non-color and length specifications is paramount for correct customs classification and efficient supply chain management.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
