A useful silk purchase starts with five separate answers: what fibres are in it, how it was made, where the fabric was produced, what a certification covers, and how you will care for the finished item. A colour you love is a good starting point. A clear label and a seller who can explain those five answers help you decide what that colour is worth to you.
You do not need to become a textile expert at the counter. Use the comparison and shopping card below to record the claims that matter. If an important answer remains unclear, pause before paying or having fabric cut.
Read the claim before judging the cloth
Treat the following as different questions:
- Fibre: Is it silk throughout, or a blend? What are the percentages and the other fibres?
- Production: Was the yarn reeled by hand? Was the cloth handwoven or machine-woven? These are separate stages.
- Origin: Where was the yarn produced, where was the fabric woven, and where was a finished garment sewn?
- Certification: Which named scheme and category apply to this particular piece?
- Care: What cleaning, drying and ironing instructions apply to the finished purchase?
“Handwoven” answers a production question; it does not supply fibre percentages. A Thai shop address identifies the seller; it does not trace the yarn. Ask the seller to connect each description to the actual scarf, garment or length of cloth you are considering.
The Royal Peacock scheme is especially useful because it sets out different requirements for Thai silk products. It is administered by the Queen Sirikit Department of Sericulture, usually shortened to QSDS. Its four colours identify named certification categories, including a category specifically for blends. QSDS explains the four-category scheme.
What the four Royal Peacock categories mean
This comparison uses the department's 2024 regulations, available from its current document collection and checked on 6 October 2026. It summarises the distinctions most useful to buyers, rather than reproducing every inspection requirement. Warp means the lengthwise yarns; weft means the yarns running across them.
| Mark and category | Fibre and production requirements in the published rules | The useful follow-up |
|---|---|---|
| Gold: Royal Thai Silk | Thai native-breed silk for both warp and weft; hand-reeling; a traditional handloom with a shuttle passed by hand. | Who made this fabric, and can I match this piece to its certification details? |
| Silver: Classic Thai Silk | Thai native or improved-breed silk in the weft and/or warp; hand-reeling and handloom weaving. | Which yarns and breed were used, and what production details are recorded? |
| Blue: Thai Silk | Genuine silk in both warp and weft. The rules allow Thai-origin or imported silk, with lawful import documentation where applicable; reeling and weaving methods are not prescribed. | Where did the yarn come from, and was the cloth handwoven or machine-woven? |
| Green: Thai Silk Blend | Silk is the main fibre, with other fibres secondary; the percentages of silk and other fibres must be stated clearly. Production method is not prescribed. | What is the complete fibre breakdown, and does the care label suit my intended use? |
All four require production in Thailand. Read the official regulations, particularly clause 11 on PDF pages 3, 7, 11 and 15. The document is in Thai; the comparison above is an English summary.
Two details prevent common misunderstandings. First, the rules for gold, silver and blue permit specified silver or gold decorative yarns within stated limits. Do not turn a Peacock colour into an assumption that every component of an embellished textile is silk. Ask about decoration separately. Second, the green category's wording does not give one universal silk percentage for every product. Read the actual composition.
Older official explanations remain online. For example, the QSDS Nong Khai summary describes limited motor-assisted reeling for silver. The newer regulation says hand-reeling. This guide follows the newer text; if a seller relies on an older certificate or description, ask QSDS to clarify its application to that item.
Use the categories to understand a production claim, then choose for your purpose. A certified blend may be exactly what you want. A gold category does not, by itself, answer whether a scarf feels comfortable on you or whether you can manage its cleaning instructions.
Check the piece, the certificate and the shop separately
Ask to see the item's mark and accompanying identification, rather than relying only on a sign behind the counter. The department says certified fabric receives a Peacock mark with a 2D barcode for tracing its production source. Its English brochure explains scanning the barcode or searching the seal number.
The official traceability catalogue describes records including the mark number, producer, fabric details, certification number and production location. It links to the QSDS traceability service. Ask the seller to help compare the returned information with the piece in front of you. A code leading only to a shop's homepage has not completed that comparison. If the service will not load, save the identifiers and resolve the question with QSDS before relying on certification as the reason to buy.
The government's certification-service guidance says the certification mark is to be displayed only on the Thai silk or Thai silk products that have been certified. That is why a shop sign cannot settle the status of every item on its shelves.
There is also a QSDS Certified Thai Silk Shop directory. Its catalogue record showed a system update of 26 February 2026 and an annual update frequency when checked. Those are catalogue details, not proof that each listed shop's certificate, address or opening hours has been rechecked today. Confirm the particular shop's current details and the particular product's certification.
The Peacock producer-certification rules provide a three-year certificate period from the date on the certificate. Read that date and ask about renewal where relevant; do not assume the shop scheme has the same term. This guide has not authenticated an individual shop or an individual piece of cloth.
Ask about the weave without using it as an authenticity test
After the label, look at what you will actually use. With the seller's permission, unfold enough of the cloth to see the pattern repeat, edges and any joins. For a finished garment, check its lining, seams and fastening as well as its outer fabric. For a scarf, try the size and drape without catching it on jewellery.
These checks help you judge condition and suitability. Shine, softness, irregular yarns or a pleasing rustle are not a certificate of fibre content or origin. Do not conduct a burn test, pull out threads or let a dramatic demonstration replace a clear composition statement.
Ask, “What technique makes this pattern?” Then ask which steps were done by hand. That keeps a claim about weaving separate from a claim about yarn preparation or decoration. If the seller gives a village or province name, clarify whether it identifies the weaving location, the maker's home, a design tradition or the shop itself.
For fabric sold by length, note the usable width as well as the length and price. Ask a tailor how much your intended garment needs before cutting. Pattern placement and the design you want are reasons to confirm the requirement together, rather than buying an assumed number of metres.
Make care part of the purchase decision
Ask to see written care instructions while you can still choose another item. “Silk blend” alone does not tell you whether the finished purchase can be washed, and a seller's general advice should be reconciled with its own label.
The Drycleaning & Laundry Institute's silk guidance identifies possible problems from home washing, including shrinkage, dye bleeding, shape changes and altered texture. Use that as a reason to obtain item-specific instructions, not as a universal cleaning recipe.
Ask these questions:
- Is professional cleaning required, or is a specified washing method permitted?
- Do the lining, embroidery, decorative threads and fastenings have the same care requirements as the outer cloth?
- What drying and ironing instructions should I follow?
- If I am buying fabric for tailoring, what preparation should my tailor discuss with you before cutting?
- Can you provide the instructions in writing, in a language I can understand?
For a gift, consider whether the recipient will want the stated upkeep. For something you plan to wear frequently, include cleaning cost and access to a suitable cleaner in your decision. Keep the label with the item and photograph it before removing a tag.

Origin: Yarn source ___; fabric production location ___; finished-item making location ___; supporting label or record ___ .
Certification: Scheme and colour/category ___; item seal or barcode ___; matching producer/product details ___; certificate dates or renewal evidence ___; unresolved questions ___ .
Use and care: Intended use ___; size or usable fabric width and length ___; cleaning, drying and ironing instructions ___; care information supplied in writing ___ .
Purchase: Total price and currency ___; cutting or alteration included ___; return/exchange conditions, especially after cutting or alteration ___; receipt description ___ .
You can show the seller this short request: “Please help me check the silk percentage, other fibres, where this fabric was made, and the care instructions. If this piece is certified, could you show me its mark and matching record? Please include the item description on the receipt.”
Before paying, choose which unanswered details would change your decision. If local yarn, handweaving or a particular certification is why you are paying more, ask for evidence of that specific claim. If your priority is a wearable gift, make sure its size and care requirements work for the recipient. Leave with a purchase you can describe accurately, plus the information needed to look after it.
