Our work brings us into contact with different customers and a wide range of valuable dried seafood. Last week, Mr Chan in Kowloon Tong contacted us. A middle-aged man attentive to his health, he takes a keen interest in diet and wellbeing.

Why decide to part with it?

Mr Chan explained that he had accumulated premium dried seafood received from relatives and friends over several years, intending to use it gradually in soups. After a recent health check, however, a nutritionist advised him to change his diet and limit rich, high-purine soups. Mrs Chan was also too busy to manage the lengthy fish-maw soaking process, so the goods remained unused in the refrigerator and moisture-proof box.

Mr Chan took a practical view: "Instead of letting good ingredients go to waste, I'd rather ask Kam Hoi Shing to help me sell them to someone who appreciates them. I can put the money towards a professional massage chair—that is more useful to me."

Professional appraisal: Witnessing top-quality dried goods

At the scheduled time, Mr. Chan brought out two treasures that immediately caught our attention.

The first item was a well-preserved jar of cordyceps. A pronounced fungal aroma emerged when it was opened. Each piece was intact, with a full larval body, short stroma and golden colour—features consistent with a high grade.

The second item was a batch of bright, translucent golden fish maw. Mr Chan had kept it well, with no sign of dampness or mould. Against the light, the pieces were highly translucent, substantial and clearly grained. They had only a light marine aroma, with no strong fishy smell, and were assessed as high-quality aged fish maw.

Our appraisers at Kam Hoi Shing explained the current market trends to Mr. Chan on the spot, and based on the dryness, size, and completeness of the goods, provided a very fair buyback price. After listening to the evaluation analysis, Mr. Chan was very satisfied with our professionalism and transparency and immediately completed the transaction.

📊 Buyback product information and market trend analysis

To make our evaluation criteria clearer to everyone, we have organized the analysis of Mr. Chan's batch of goods into the following table:

Product Category Evaluation Standards and Product Condition Recent Market Trend Analysis
Cordyceps

Condition: Full bodies, clean yellow colour, no breakage and more than 95% dry.


Evaluation: High-grade specification, pronounced aroma and excellent storage condition, with no inserted bamboo supports or signs of added water.

The source notes that climate conditions have affected wild cordyceps supply in recent years. Demand remains strong for large, high-quality specimens, particularly intact stock in its natural condition, and buyback quotations have remained comparatively firm.
Premium fish maw

Condition: Substantial body, intact edges, translucent deep-yellow colour, no oily odour and thoroughly dry.


Evaluation: Well aged, with the changes expected in properly stored fish maw; suitable for soup and actively traded in the resale market.

Demand for fish maw has continued to rise. Compared with newer stock, properly stored aged fish maw generally has a better rehydration yield, smoother texture and milder fishy aroma. Good examples can therefore command a noticeable premium in the buyback market.

💡 Product-related FAQ

Q1: How do I determine how much my fish maw or cordyceps at home is worth?

A: The value of dried seafood depends on many factors. For cordyceps, mainly consider the origin, the strand count (i.e., how many strands per gram, fewer strands mean larger and more valuable), dryness, and completeness; for fish maw, mainly consider the variety (such as white fish maw, croaker fish maw, etc.), thickness, head count, and translucency. The most accurate way is to take a few clear photos and send them to us at Kam Hoi Shing. We will provide you with a free preliminary appraisal.

Q2: If the packaging has been opened, or the original box is missing, do you still accept it?

A: Absolutely! At Kam Hoi Shing buyback, we mainly look at the quality and authenticity of the dried seafood itself, not just the packaging. Like Mr. Chan, even if it's stored in an ordinary transparent bottle, as long as the product is genuine and well-preserved, we will still offer a competitive buyback.

Q3: What is the transaction process? Is it safe?

A: The process is very simple and safe. You can first send photos to us via WhatsApp or WeChat for a preliminary quote. If you feel the price is acceptable, we can arrange for a professional to collect the items at no charge, or meet at a safe public location. After on-site verification, payment is made immediately in cash or via bank transfer, no delays.

If you have unused premium dried seafood at home, consider an appraisal before its condition declines. Kam Hoi Shing provides a professional buyback service with transparent quotations.
