Paper
The best-documented westward journey on this list, and a good lesson in legend versus evidence. Tradition credits the court official Cai Lun with paper in 105 CE, but fragments from Gansu are far older, reaching back to the 2nd century BCE.
The famous story says Chinese prisoners taken at the Battle of Talas in 751 taught papermaking to Samarkand. Historians doubt it: no contemporary Arab source describes the battle, and paper was already in use there decades earlier. What is solid is the chain that followed. Abbasid Baghdad had paper mills by 794 to 795, Cairo merchants were wrapping spices in paper by 1035, and the first recorded paper mill on the Iberian Peninsula was at Xàtiva in 1056. Italy's mills followed in the 13th century.

Sericulture
Silk production
Raising silkworms and reeling their cocoons began in China in the Neolithic period. Silk cloth traveled west for centuries before the know-how did, which is what makes the transfer so interesting.
The technique moved in stages. It reached Khotan in the Tarim Basin by the first half of the 1st century CE and was established in India by 140 CE. Byzantium acquired it in the early 550s, when, according to the historian Procopius, monks who had learned the craft in a land he calls Serinda brought silkworm eggs to Emperor Justinian. The hollow canes of later retellings are not in his account. In 1147, after raiding Corinth and Thebes, Roger II of Sicily set up silkworks in Palermo and Calabria, taking the industry into the West.

Compass
The magnetic compass
The first incontestable Chinese reference to a magnetized needle comes from Shen Kuo's Dream Pool Essays in 1088, written for geomancers rather than sailors. Within a few decades Zhu Yu's Pingzhou Table Talks, from 1111 to 1117, describes sailors who look at the south-pointing needle in dark weather.
Europe's first description, Alexander Neckam's of about 1190, actually predates the earliest known Islamic reference, a Persian story collection of 1232. That awkward order is why this entry is genuinely contested. Some historians argue that Arab sailors carried the idea from China to Europe; others propose a separate European invention. Either way, the Chinese evidence comes first by about a century.

Gunpowder
Gunpowder began as a by-product of the search for an elixir of life. Tang-era Daoist texts give the earliest evidence, from 808 and about fifty years later, and the earliest chemical formula for gunpowder appears in the Wujing Zongyao, compiled by Zeng Gongliang between 1040 and 1044.
Westward, the dates bunch up in the 13th century, the age of the Mongol conquests. The Syrian writer Hasan al-Rammah recorded recipes and methods for purifying saltpeter between about 1240 and 1280, and Roger Bacon's descriptions of 1267 are the earliest in the West. The Mongols are the usual suspects as carriers, but no clear transmission route is documented, so the "how" remains an open question even though the Chinese priority is not.

Trebuchet
The traction trebuchet
Before the famous counterweight machines of medieval castles came the traction trebuchet, a long throwing arm hauled down by a crew pulling on ropes. Its first recorded use is in ancient China, probably by the Mohists as early as the 4th century BCE, with descriptions in the Mozi.
It is the clearest military handoff here. By the 6th and 7th centuries, Byzantines, Persians, Arabs and Avars had all adopted it, and whatever the exact route, it was in the eastern Mediterranean by the late 6th century: the Avars and Slavs used traction trebuchets against Thessaloniki in 586. Arab armies took it up in the second half of the 7th century. The later counterweight version has no agreed birthplace, so it is a separate story.

Porcelain
Porcelain is the case where the objects traveled long before the method. Glazed stoneware had become porcelain by the Eastern Han dynasty, and by the late Sui and early Tang potters had achieved the whiteness and translucency the word now implies. By the 9th century Tang wares were being exported to the Islamic world, where they were highly prized.
Europe's first mention is in Marco Polo's 13th-century account, and Florence's Medici porcelain of the 16th century was the first real attempt to copy it, with little success. The recipe itself was cracked at Meissen in Saxony, where the first hard European porcelain was made in 1708. The Jesuit François Xavier d'Entrecolles's letters from 1712 then spread detailed Chinese methods across Europe.

Banknote
Paper money
The westward trip of paper money is documented almost to the year, and it ended badly. Notes called jiaozi began as a private merchant scheme in Chengdu under the Song, and after several issuers went bankrupt the government took over, founding an official note office in 1023.
The Yuan dynasty's notes impressed foreign visitors, Marco Polo's account among them. In 1294 Gaykhatu, the Mongol ruler of the Ilkhanate in Persia, introduced paper money in Tabriz, modeled so closely on Yuan notes that they even carried Chinese words. The experiment collapsed within about two months, and Gaykhatu was overthrown and killed soon after. Include it for what it shows: a transfer that is fully on record can still fail to take root.

Playing card
Playing cards were most likely invented in Tang China around the 9th century, closely tied to woodblock printing, though whether they descend from the old "leaf" game described by the Song scholar Ouyang Xiu is disputed.
The route west runs through Egypt. Cards were spreading across Asia by the 11th century and later reached Egypt, where the Mamluks played with four suits of polo sticks, coins, swords and cups. Europe's cards most likely came from those Mamluk decks, and the earliest European mention, in a Catalan rhyming dictionary of 1371, points to Spain as the entry point. The exact steps between Chinese cards and the Mamluk deck are not recorded, but the direction of travel is clear.
