Asli vs Nakli Plywood Kaise Pehchane? ISI Mark, Core aur Bill Check (2026)

Nakli plywood ka problem kya hai?

Plywood ek baar furniture mein lag gaya toh 10–20 saal wahi chalta hai. Problem tab hoti hai jab commercial (MR) ply par BWR ya BWP ka stamp laga ke bech diya jaata hai, ya kisi bade brand ka naam copy karke sasta sheet thama diya jaata hai. Shuru mein farak nahi dikhta – 1–2 monsoon ke baad kitchen ke neeche wala cabinet phoolne lagta hai, layers alag hone lagti hain, screw nikalne lagte hain.

Achhi baat ye hai ki kuch simple checks se aap dukaan par hi kaafi had tak pehchan sakte hain.

1. ISI mark aur IS number check karein

Har genuine sheet ke face par brand ke saath ISI mark aur ek IS number print hota hai:

• IS 303 – general purpose plywood (MR aur BWR grade)
• IS 710 – marine plywood (BWP/marine grade)

ISI mark ke neeche ek CM/L licence number bhi hota hai. Ye number BIS ki website par check kiya ja sakta hai ki licence kis company ke naam par hai. Agar stamp dhundhla hai, number nahi hai, ya grade (MR/BWR/BWP) likha hi nahi – toh ruk jaiye.

👉 Waterproof kaam ke liye BWP & marine plywood aur kitchen/wardrobe ke liye BWR plywood dekhein.

2. Edge dekh kar core check karein

Sheet ki side (edge) par saari layers dikhti hain. Dhyan se dekhiye:

• Layers ke beech khali jagah (gaps) ya overlap toh nahi?
• Beech mein patches ya tukde jodkar bhara hua core toh nahi?
• Full-core sheet mein har layer hardwood ki hoti hai – alternate-core mein kuch layers halki lakdi ki hoti hain (ye nakli nahi hai, bas sasta option hai – lekin dukaandar ko saaf batana chahiye).

Gaps wala core screw pakad nahi paata aur beech se bend ho jaata hai.

3. Weight aur surface

• Same thickness aur size ki do sheets uthakar dekhiye – bahut zyada halki sheet mein aksar core kamzor hota hai.
• Face veneer ek jaisa, smooth aur bina bade patch ke hona chahiye.
• Sheet sidhi rakh kar dekhiye – wavy ya twisted sheet se shutter kabhi seedha nahi baithega.

4. Chhota boil test (BWR/BWP ke liye)

Agar aap bada order de rahe hain toh ek chhota offcut maang lijiye aur ghar par paani mein kuch ghante ubaal kar dekhiye. Achhe BWR/BWP plywood ki layers alag nahi honi chahiye. MR (commercial) ply is test mein fail ho sakta hai – aur wo normal hai, kyunki wo dry areas ke liye bana hai.

5. Warranty card aur GST bill zaroor lein

• Branded plywood par aksar 15–25 saal ki warranty aati hai – warranty tabhi valid hoti hai jab GST bill ho.
• Bill par brand, grade, thickness aur quantity likhi honi chahiye.
• Kai brands sheet par QR code ya hologram dete hain jisse authenticity check hoti hai.

6. Bahut sasta = sochne wali baat

Agar kisi brand ka BWP sheet baaki dukaanon se bahut kam rate par mil raha hai, toh ya toh grade alag hai ya sheet genuine nahi hai. Rate compare karte waqt same brand, same grade, same thickness compare karein.
