Customs are lying to us and they Declare our parcel is As TOY [Which is Wrong Declaration] but you can check your RTF heli or RTF plane Manual.
In your Manual They Declare This is
"NOT A TOY" .
They also mention This is not For under 14 year age.
That BAN policy is only for "TOYS" which is Appearing in chapter 9501,9502,9503.
Please Note that Many Item is included in the chapter 9503 that all item is NOT A TOY.So you can also prefer AMA Document.
The Policy is For TOYS not For Reduced-size (“scale”) models and similar recreational models.
That Our All heli and plane is comes under Reduced size model..
