Walk through Myeongdong or browse a Korean marketplace and you will see enormous quantities of K-pop merchandise that no label ever licensed. It is not hidden, it is not always low quality, and for a buyer the distinction matters for price, for authenticity claims and occasionally for customs.
The identifying marks
Official goods carry a label or agency copyright line, a hologram or authentication sticker on many categories, and a barcode registered to the licensee. Unofficial goods carry none of these. The copyright line printed in small text on the back is the most reliable single check. Hologram stickers are the easiest check on lightsticks and larger merchandise, since the agencies apply them consistently and counterfeit versions rarely reproduce them well.
Where each is sold
Official goods come from the artist's own shop, Weverse, recognized album counters and licensed pop-ups. Unofficial goods dominate tourist districts, open marketplaces and a large share of listings on Korean secondhand platforms, usually described honestly as fan-made or non-official. Prices tell you most of what you need to know, since an official lightstick at a third of its retail price is either used, unofficial, or not going to arrive.
Quality is not the differentiator
Some unofficial goods are genuinely well made and some official merchandise is disappointing. The reason to care is price integrity: unofficial items should cost a fraction of official ones, and paying official prices for unlicensed goods is the actual harm. Sellers of fan-made goods in Korea generally label them clearly as such, so the honesty problem is more common on international resale platforms than on Korean ones.
Customs and trademark exposure
Small quantities of personal-use fan goods pass without issue. Commercial quantities of items reproducing official logos and artist likeness can be seized as counterfeit, which is a real risk for anyone importing to resell rather than to keep. Anyone importing in quantity should also consider that the agency, not customs, is usually the party that initiates enforcement against counterfeit merchandise.

Do photocards have official markings?
Official cards carry a copyright line and album identifier on the back. Fan-made cards typically omit it or use obviously different text.
Is buying unofficial goods wrong?
It is legal in Korea and common. The concern is misrepresentation, not the goods themselves.
Can I resell unofficial goods in the US?
Reselling items reproducing protected logos or likenesses exposes you to trademark claims. Personal collecting does not.
