HS Code 37.07 – Chemical preparations for photographic uses (other than varnishes, glues, adhesives and similar preparations); unmixed products for photographic uses, put up in measured portions or for retail sale
What HS 37.07 covers
Heading 3707 encompasses chemical preparations specifically formulated for photographic uses, excluding varnishes, glues, adhesives, and similar preparations. It also includes unmixed products intended for photographic uses, provided they are put up in measured portions or for retail sale. This classification is crucial for chemicals like developers, fixers, stop baths, bleaches, and toners, which are essential for traditional silver-halide photography, X-ray imaging, and various industrial photographic processes. The scope is defined by the *intended use* and *presentation* of the chemicals. If a chemical has a general application but is packaged or formulated explicitly for photography, it falls here. Conversely, if a chemical is merely a raw ingredient without photographic specific preparation or packaging, it would likely fall under Chapters 28 or 29. This heading plays a vital role in supporting the analog photography industry, medical imaging, and specialized industrial applications where chemical processing of film or paper is still prevalent. Its significance for trade compliance lies in correctly identifying these specialized chemical mixtures, which often have different regulatory requirements and tariff rates than general-purpose chemicals. This ensures proper classification and adherence to safety and environmental regulations associated with photographic chemicals. As part of Chapter 37, it reinforces the category of goods dedicated to photographic and cinematographic industries.

- Examples
A German chemical manufacturer might export bulk photographic developer concentrates to a large film processing laboratory in Japan, transported by sea freight across major global shipping lanes. Concurrently, a US company could import pre-packaged photographic chemical kits, designed for amateur darkroom enthusiasts, from a specialized supplier in China, typically via containerized ocean shipping. Furthermore, a medical supply distributor in Brazil might import X-ray film processing solutions from a specialized producer in Switzerland, often via air cargo due to the time-sensitive nature of medical supplies.

Codes often confused with 37.07
Common mistake. Common misclassification errors occur when general-purpose chemicals (Chapters 28 or 29) are incorrectly placed here if they are not specifically prepared or packaged for photographic use. For example, sodium thiosulfate in bulk form for general chemical use would be in Chapter 28, but if it's pre-measured and labeled as a photographic fixer, it belongs in 3707. Conversely, varnishes, glues, or adhesives, even if used in conjunction with photography, are explicitly excluded from 3707 and generally fall under Chapter 32 or 35. Another mistake is confusing complex chemical mixtures not elsewhere specified (3824) with 3707; the 'photographic uses' criteria is paramount for 3707.
Top exporters and importers of HS code 3707, 2025
In 2025, the largest exporter of HS code 3707 in UN Comtrade data was Japan, with 51% of world exports; the largest importer in UN Comtrade data was China, with 37% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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. UN Comtrade records Taiwan as "Other Asia, not elsewhere specified". Saudi Arabia's exports under that code are left out: they are far too large to be trade with Taiwan, so mostly undisclosed partners. 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).
