HS Code 7104Stones; synthetic or reconstructed precious or semi-precious, whether or not worked or graded but not strung, mounted or set; ungraded synthetic or reconstructed precious or semi-precious stones, temporarily strung for convenience of transport

What HS code 7104 covers

Heading 7104 is for stones that people have made. They were not simply dug out of the ground in that form. The official name says "synthetic or reconstructed". Synthetic means grown in a lab. Reconstructed means built up from smaller pieces of real stone.

The stones can be precious or semi-precious. Lab-grown diamonds belong here. So does piezo-electric quartz, a special quartz used in electronics.

The heading is part of Chapter 71, which deals with pearls, precious stones and metals. Some traders write it as HSN 7104. The four digits are the same, and they are used for customs classification.

Subheadings 710410 to 710499: unworked or worked

Each six-digit code answers two things. What is the stone, and how far has it been worked? Here is each code in short form:

• 710410: piezo-electric quartz, plus ungraded man-made stones strung only for transport
• 710421: diamonds, rough or simply sawn
• 710429: all other man-made stones, rough or simply sawn
• 710491: diamonds that are cut, polished or graded, but not strung, mounted or set
• 710499: all other man-made stones that are cut, polished or graded, but not strung, mounted or set

Unworked versus worked stones

"Unworked or simply sawn or roughly shaped" means the stone is still rough. It may have been sawn from a bigger piece, but it is not finished. Rough diamonds go to 710421. Other rough stones go to 710429.

"Worked or graded" means the stone has been cut, polished or sorted by quality. Finished diamonds go to 710491. Other finished stones go to 710499. They must still be loose, not strung, mounted or set.

A stone that is strung only to make it easier to move still counts as a loose stone. Once it is mounted or set into a finished piece, it leaves this heading. Look at HS 7113 for jewellery or HS 7116 for articles made of stones.

Laboratory grown diamonds HS code

Many people ask for the HS code for lab-grown diamonds. Because they are man-made, they sit in heading 7104 and not with mined diamonds.

The split is by how much work has been done. A rough stone fits 710421. National tariffs can add extra digits after the six-digit code, so check your own country's list too.

7104 vs 7102, 7103, 7105 and 7116

Several nearby headings are easy to mix up with 7104. Use this short guide:

• HS 7102 covers diamonds, whether worked or not, but not mounted or set. Think of it as the natural diamond heading.
• HS 7105 covers dust and powder of stone. If the goods are ground into powder, look there.
• HS 7116 covers articles made of pearls or stones, whether natural, synthetic or reconstructed. If the stones have been made into articles, look there.
