Every buyer at a trade fair has seen it: the sample in the booth is a different product than the pallet in your warehouse. Not because of bad faith, usually. Because a booth sample is made by the best hands in the company, chosen from the best run of the year, displayed under the best light, and photographed from the best angle. The production line that will make your order is a different room with different hands, a different shift, and the raw material that was actually available that month. The gap between those two rooms is where most supply problems are born, and it is entirely visible if you ask the right questions at the fair instead of after the delivery.

Question 1: Is this sample what your production line is running right now?

A booth sample can be a hero piece, made for display. That is normal and honest, as long as it is disclosed. The question is not accusatory, it is informational. If the answer is no, follow up with when the production-line equivalent will be available and where it is in the current run. A supplier who can walk you to a production sample that week, taken from an active order, is showing you the real product. A supplier who can only show you the hero piece is showing you a possibility.

Question 2: What is the acceptable color spread within a single run, and how is it measured?

Every batch has a spread, the question is whether the spread is a number or a feeling. A controlled factory states a tolerance, a delta-E value, a light-box comparison, something you can point to. An uncontrolled factory says it looks consistent and hopes you do not compare two units side by side under neutral light. Ask for the number, and ask for the instrument. If the answer is a number, write it down and put it on the spec sheet. If the answer is a feeling, that is the answer.

Question 3: Where does the UV testing come from, and what is the pass condition?

UV resistance is a test, not a promise. ISO 105-B02, a xenon arc lamp, a number of hours, and a grey-scale rating for the color shift after that number of hours. Ask for all four. A supplier who has run the test can tell you the hours, the rating, and the date of the last run. A supplier who has not run the test will tell you it is good quality and move the conversation to price. Both are honest answers, but they are not the same answer.

Question 4: What is your monthly capacity, and what are you actually using right now?

Stated capacity and used capacity are different numbers, and the gap between them is your real lead time. A factory at 90 percent of capacity has a tight schedule and a real reason to miss a date. A factory at 40 percent has room, but also a reason to wonder why. Neither number is good or bad, both are information. Ask both, and the answer to the second one tells you more about the company than the answer to the first.

Question 5: What is your failure rate on orders in your largest markets, and what does a failure look like?

A factory with no failure rate has either no customers or no honesty. Ask for the rate and the shape: is it a color drift on a single container, a packing error, a late shipment, a leaf breakage rate that exceeded the agreed tolerance? The shape of the failure tells you where the factory is weak, and where you should put your inspection energy. A supplier who can name their failure modes is describing a quality system. A supplier who cannot is describing an absence.

Question 6: Will you run a production sample with my order, before full production?

A pre-production sample, or PPS, is a small run of ten to twenty units made on the production line with the production materials, shipped to you before the full run starts. It is the single cheapest piece of insurance in the entire chain. A supplier who says yes without hesitation has one in their routine. A supplier who says it is extra cost or extra time is telling you it is not in their routine, and you should plan the relationship accordingly.

Question 7: Who signs the spec sheet, and what happens if the batch fails it?

A spec sheet with a signature is a document. A spec sheet without one is a conversation. Ask who signs, and ask what the remedy is when the batch does not meet the signed specification: rework, replacement, a credit, a defined window. The clarity of the answer is the clarity of the company. A factory with a documented remedy is a factory that has done this before. A factory with a vague remedy is a factory that has not.

Question 8: May I visit the production floor before I place the order?

This is the final question and the one that matters most, because it is the only one that costs the supplier something. A supplier who says yes, with a date, is showing you that the production floor is a place that can be seen. A supplier who says it is not possible, for security, for the client, for the moment, is showing you that the production floor is a place that prefers to be hidden. Both are real answers. The fair is the cheapest moment to find out which one you got.

Eight questions, twenty minutes at the booth, and you have more signal than most buyers carry into their first container. None of them require a lawyer, a lab, or a visit. They require a pen and the willingness to write the answer down. The fair is a room full of people selling the same forty leaves. The questions are what separate the leaf from the plant.

If you are planning a visit to Canton Fair and want the eight questions adapted to your specific product line, with the tolerance numbers and the UV pass conditions filled in for your SKU, our team will prepare the sheet before your trip and walk you through it at the booth, side by side, with two or three alternative constructions. The questions do the audit. The sample just has to answer them.
